IGI (based on EMI) Installation and Configuration

Common Installation

OS installation

Install SL5 using SL5.X repository (CERN mirror) or one of the supported OS (RHEL5 clones).

You may find information on official OS repositories at Repositories for APT and YUM
If you want to set up a local installation server please refer to Mrepo Quick Guide

NOTE: Please check if NTP , cron and logrotate are installed, otherwise install them!

Check the FQDN hostname

Ensure that the hostnames of your machines are correctly set. Run the command:

hostname -f

It should print the fully qualified domain name (e.g. prod-ce.mydomain.it). Correct your network configuration if it prints only the hostname without the domain. If you are installing WN on private network the command must return the external FQDN for the CE and the SE (e.g. prod-ce.mydomain.it) and the internal FQDN for the WNs (e.g. node001.myintdomain).

Disabling SELinux

# disabled - No SELinux policy is loaded.
SELINUX=disabled

... and then reboot the system.

EMI release useful link

If you don't find useful information in this documentation please have also a look to the official EMI documentation:

• EMI 1 product pages
• EMI 1 updates pages
• EMI 2 product pages
• EMI 2 updates pages

Repository Settings

To have more details to the repository have a look to the this link Repository Specifications

If not present by default on your SL5/x86_64 nodes, you should enable the EPEL repository (https://fedoraproject.org/wiki/EPEL)

If not present by default on your SL6/x86_64 nodes, you should enable the EPEL repository (https://fedoraproject.org/wiki/EPEL)

EPEL has an epel-release package that includes the gpg key used for package signing and other repository information, like the .repo files.
Tto use normal tools such as yum to install packages and their dependencies

• for SL5/x86_64 install http://download.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
• for SL6/x86_64 install http://ftp-stud.hs-esslingen.de/pub/epel/6/x86_64/epel-release-6-7.noarch.rpm

By default the stable EPEL repo is enabled. Example of epel-5.repo file:

[extras]
name=epel
mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=epel-5&arch=$basearch
protect=0

IMPORTANT NOTE:

• If present remember to disable the dag.repo if it is enabled.

You need to have enabled only the following repositories: Operating System, EPEL, Certification Authority, EMI, IGI. Please see the table bellow for details:

SL5 x86_64		SL6 x86_64
EMI1	EMI2	EMI2
EPEL 5 repo - please use epel-release-5-4.noarch.rpm	EPEL 5 repo - please use epel-release-5-4.noarch.rpm	EPEL 6 repo - please use epel-release-6-8.noarch.rpm
EMI 1 repos - please use emi-release-1.0.1-1.sl5.noarch.rpm	EMI 2 repos - please use emi-release-2.0.0-1.sl5.noarch.rpm	EMI 2 repos - please install this emi-release-2.0.0-1.sl6.noarch.rpm
EGI trust anchors repo - egi-trustanchors.repo	EGI trust anchors repo - egi-trustanchors.repo	EGI trust anchors repo - egi-trustanchors.repo
IGI (1) repo - igi-emi.repo	IGI (2) repo igi-emi2.repo	IGI (2) repo - igi-emi2.repo

It is strongly recommended the use of the lastest version of the emi-release packages mentioned above as they containing the EMI public key and the yum .repo files, that ensures the precedence of EMI repositories over EPEL.

Example:for EMI 1 case

# rpm --import http://emisoft.web.cern.ch/emisoft/dist/EMI/1/RPM-GPG-KEY-emi
# wget http://repo-pd.italiangrid.it/mrepo/EMI/1/sl5/x86_64/updates/emi-release-1.0.1-1.sl5.noarch.rpm
# yum localinstall emi-release-1.0.1-1.sl5.noarch.rpm

Updating from EMI 1 to EMI 2

For the update to EMI 2 you have to uninstall the old emi-release package and install the new one:

# rpm -e emi-release
# rpm -ivh http://emisoft.web.cern.ch/emisoft/dist/EMI/2/sl5/x86_64/base/emi-release-2.0.0-1.sl5.noarch.rpm

Important note on automatic updates

Several site use auto update mechanism. Sometimes middleware updates require non-trivial configuration changes or a reconfiguration of the service. This could involve service restarts, new configuration files, etc, which makes it difficult to ensure that automatic updates will not break a service. Thus

WE STRONGLY RECOMMEND NOT TO USE AUTOMATIC UPDATE PROCEDURE OF ANY KIND

on the IGI/EMI middleware repositories (you can keep it turned on for the OS). You should read the update information provides by each service and do the upgrade manually when an update has been released!

Tips & Tricks:

• Running the script available at http://forge.cnaf.infn.it/frs/download.php/101/disable_yum.sh (implemented by Giuseppe Platania (INFN Catania) wil disable the yum-autoupdate.

Generic Configuration

Configuration files

IGI YAIM configuration files

YAIM configuration files should be stored in a directory structure. All the involved files HAVE to be under the same folder <confdir>, in a safe place, which is not world readable. This directory should contain:

File or Directory	Scope	Example	Details
<your-site-info.def>	whole-site	ig-site-info.def	List of configuration variables in the format of key-value pairs. It's a mandatory file. It's a parameter passed to the ig_yaim command. IMPORTANT: You should always check if your <your-site-info.def> is up-to-date comparing with the last /opt/glite/yaim/examples/siteinfo/ig-site-info.def template deployed with ig-yaim and get the differences you find. For example you may use vimdiff: vimdiff /opt/glite/yaim/examples/siteinfo/ig-site-info.def <confdir>/<your-site-info.def>
<your-wn-list.conf>	whole-site	-	Worker nodes list in the format of hostname.domainname per row. It's a mandatory file. It's defined by WN_LIST variable in <your-site-info.def>.
<your-users.conf>	whole-site	ig-users.conf	Pool account user mapping. It's a mandatory file. It's defined by USERS_CONF variable in <your-site-info.def>. IMPORTANT: You may create <your-users.conf> starting from the /opt/glite/yaim/examples/ig-users.conf template deployed with ig-yaim, but probably you have to fill it on the base of your site policy on uids/guis. We suggest to proceed as explained here: ”<a href="http://igrelease.forge.cnaf.infn.it/doku.php?id=doc:use_cases:users" title="doc:use_cases:users">Whole site: How to create local users.conf and configure users</a>”.
<your-groups.conf>	whole-site	ig-groups.conf	VOMS group mapping. It's a mandatory file. It's defined by GROUPS_CONF variable in <your-site-info.def>. IMPORTANT: You may create <your-groups.conf> starting from the /opt/glite/yaim/examples/ig-groups.conf template deployed with ig-yaim.
<vo.d>	whole-site	vo.d	In this directory shuld be the VO name files containing the VO configuration It's not a mandatory directory. bus should be useful

Known issues

• BDII_DELETE_DELAY default value is missing for services other than BDII site & top.
  • Workaround - add to your site-info.def BDII_DELETE_DELAY=0

Additional files

Furthermore the configuration folder can contain:

# cat vo.d/lights.infn.it
SW_DIR=$VO_SW_DIR/lights
DEFAULT_SE=$SE_HOST
VOMS_SERVERS="vomss://voms2.cnaf.infn.it:8443/voms/lights.infn.it?/lights.infn.it"
VOMSES="lights.infn.it voms2.cnaf.infn.it 15013 /C=IT/O=INFN/OU=Host/L=CNAF/CN=voms2.cnaf.infn.it lights.infn.it"

The optional folders are created to allow system administrators to organise their configurations in a more structured way.”

NTP Configuration

Check if the NTP is installed in your O.S.
If you have installed the middleware, and you have the package glite-yaim-core in your host you have to get the repo igi-emi.repo and inside it there is a rpm called yaim-addons. Please install it:

wget http://repo-pd.italiangrid.it/mrepo/repos/igi/sl5/x86_64/igi-emi.repo
yum install yaim-addons

After that you can use yaim to configure ntrp:

/opt/glite/yaim/bin/yaim -r -d 6 -s <site-info.def> -n <node_type> -f config_ntp

BDII Site installation and Configuration

Have a look to the section Repository Settings of this documentation and ensure to have the common .repo files.
Before starting the installation procedure remember to clean all yum cache and headers:

yum clean all

CAs installation:

• Install CAs on ALL profiles:

yum install ca-policy-egi-core

Service installation

• Install the BDII_site metapackage, containing all packages needed by this service:

# yum install emi-bdii-site 

Service Configuration

To proper configure the BDII site profile you have to customize this file with you site parameter:

• ig-site-info.def

If you would like to cutomize the BDII_site service you can modify the variables in the service-specific file in the services/ directory. You will find an example in:

/opt/glite/yaim/examples/siteinfo/services/glite-bdii_site

YAIM Verification

• Before starting the configuration PLEASE TEST that you have defined all the mandatory variables and that all configuration files contain all the site-specific values needed:

 /opt/glite/yaim/bin/yaim -v -s <site-info.def> -n BDII_site

SITE_NAME
SITE_LOC
SITE_LAT
SITE_LONG
SITE_WEB
SITE_SECURITY_EMAIL
SITE_SUPPORT_EMAIL
SITE_OTHER_GRID
SITE_BDII_HOST
BDII_REGIONS

Most of those are in the file ig-bdii_site in directory services (the better things is to modify it). Remember in particular to set:

SITE_OTHER_GRID="WLCG|EGI"
SITE_OTHER_EGI_NGI="NGI_IT"

If no errors are reported you can proceed to the configuration, otherwise correct them before continuing.

YAIM Configuration

Please use the debug flag ( "-d 6") to configure the services in order to have detailed information. For your convenience you can save all the configuration information in a log file you can look at any time, separated from the yaimlog default one.

/opt/glite/yaim/bin/yaim -c -d 6 -s <site-info.def> -n BDII_site 2>&1 | tee /root/conf_BDII.`hostname -s`.`date +%Y-%m-%d-%H-%M-%S`.log

StoRM installation and Configuration

Have a look to the section Repository Settings and ensure that you have the common repo files.
Before starting the installation procedure remember to clean all yum cache and headers: has been updated with a Globus version higher and some profile such as StoRM and DPM has problem with this version, so please use the UMD repositories. Have a look to Repository Settings

yum clean all

IMPORTANT NOTES:

• StoRM Backend v. 1.8.2.2 (EMI 1) - If the Storage Area root of a Storage Area residing on a GPFS filesystem is specified as link pointing to the real directory and the link resides on a non GPFS filesystem a sanity check at bootstrap will fail preventing the service to start.
  • As a workaround the user can modify the definition of the Storage Area root to the real directory path rather than the link
• StoRM Backend v. 1.9.0 (EMI 2): - Due to a Known Issue on StoRM backend this release is not suited for GPFS installations.
• YAIM-STORM v, 4.2.1-3 - Starting from this release the XFS file system is managed by StoRM as a standard POSIX file system. All StoRM installations on XFS file system from this release on must specify at YAIM configuration time "posixfs" as file system type. See StoRM System Administration Guide 1.3.3 for more details.
  • Description: Specifying at YAIM configuration time "xfs" as file system type will produce an invalid namespace.xml preventing BackEnd service to boot.
    • As workaround XFS users have to specify "posixfs" as file system type.

StoRM Prerequisites

Host certificate installation:

Hosts participating to the StoRM-SE (FE, BE and GridFTP hosts) must be configured with X.509 certificates signed by a trusted Certification Authority (CA). Usually the hostcert.pem and hostkey.pem certificates are located in the /etc/grid-security/ directory, and they must have permission 0644 and 0400 respectively:

Check existence

[~]# ls -l /etc/grid-security/hostkey.pem
-r-------- 1 root root 887 Mar 1 17:08 /etc/grid-security/hostkey.pem
[~]# ls -l /etc/grid-security/hostcert.pem
-rw-r--r-- 1 root root 1440 Mar 1 17:08 /etc/grid-security/hostcert.pem

Check expiration

[~]# openssl x509 -in hostcert.pem -noout -dates

Change permission: (if needed)

[~]# chmod 0400 hostkey.pem
[~]# chmod 0600 hostcert.pem

ACL SUPPORT

Check ACL:

[~]# touch test
[~]# setfacl -m u:storm:rw test

[~]# getfacl test
  # file: test
  # owner: root
  # group: root
  user::rw-
  user:storm:rw-
  group::r--
  mask::rw-
  other::r--

[~]# rm -f test

Install ACL (eventually):
If the getfacl and setfacl commands are not available on your host:

[~]# yum install acl

Enable ACL (if needed):
To enable ACL, you must add the acl property to the relevant file system in your /etc/fstab file. For example:

[~]# vi /etc/fstab
  ...
  /dev/hda3             /storage         ext3         defaults, acl           1 2
  ...

Then you need to remount the affected partitions as follows:

 [~]# mount -o remount /storage

EXTENDED ATTRIBUTE SUPPORT

 
[~]# touch testfile
[~]# setfattr -n user.testea -v test testfile
[~]# getfattr -d testfile
  # file: testfile
  user.testea="test"
[~]# rm -f testfile

Install attr (eventually):
If the getfattr and setfattrl commands are not available on your host:

[~]# yum install attr

Enable EA (if needed):
To set extended attributes, you must add the user_xattr property to the relevant file systems in your /etc/fstab file. For example:

[~]# vi /etc/fstab
   ...
   /dev/hda3         /storage       ext3        defaults,acl,user_xattr     1 2
   ...

Then you need to remount the affected partitions as follows:

[~]# mount -o remount /storage

CAs installation:

• Install CAs on ALL profiles:

yum install ca-policy-egi-core

Service installation

* Install the StoRM metapackages, containing all packages needed by these four services. You can install StoRM in one host or in more hosts. The mandatory profiles to install are emi-storm-backend-mp, emi-storm-frontend-mp and emi-storm-globus-gridftp-mp. The other profiles are optional, have a look to the StoRM documentation System Administrator Guide to determinate if you need also emi-storm-gridhttps-mp or checksum.

The most common installation using one host:

yum install emi-storm-backend-mp
yum install emi-storm-frontend-mp
yum install emi-storm-globus-gridftp-mp

Service Configuration

To proper configure the StoRM BackEnd and FrontEnd profiles you have to customize the ig-site-indo.def file with you site parameter:

• ig-site-info.def
  
• ig-users.conf
  
• ig-groups.conf

YAIM Verification

• Before starting the configuration PLEASE TEST that you have defined all the mandatory variables for all the StoRM profiles.

 /opt/glite/yaim/bin/yaim -v -s <site-info.def> -n  se_storm_backend -n se_storm_frontend -n se_storm_gridftp
 

You can find in this documentation: System Administrator Guide all mandatory variables. In the section GENERAL YAIM VARIABLES

If no errors are reported with the verification you can proceed to the configuration, otherwise correct them before continuing with the configuration.

YAIM Configuration

Before configuring please pay attention:

• if you are installing a new StoRM in a new host you can continue
• if you are updating StoRM to a new release please follow this documentation containing useful information for the service upgrade and for the stored data files:
  
  • Upgrade_Instructions_to_StoRM_v18.pdf: Upgrade StoRM istructions.

Please use the debug flag ( "-d 6") to configure the services in order to have detailed information. For your convenience yo can save all the configuration information in a log file you can look at any time, separated from the yaimlog default one.

# /opt/glite/yaim/bin/yaim -c -d 6 -s -n  se_storm_backend -n se_storm_frontend -n se_storm_gridftp 2>&1 | tee /root/conf_StroRM_BE_FE_Gftp.`hostname -s`.`date +%Y-%m-%d-%H-%M-%S`.log

IMPORTANT NOTE The order of the profile is important and must be : -n se_storm_backend -n se_storm_frontend

Service Testing - Reference Card

After service installation to have a look if all were installed in a proper way, you could have a look to Service StoRM Reference Card. In this page you can found were all the log files are written, what daemons are running after installation and any other useful service information.

CREAM CE using DGAS accounting - Installation and Configuration

Have a look to the section Repository Settings and ensure that you have the common repo files.
Before starting the installation procedure remember to clean all yum cache and headers:

# yum clean all

The CREAM CE Services were tested with gLite WN SL5/SL6 x86_64 and also with ig_WN SL5/SL6 x86_64.

CREAM CE Prerequisites

Host certificate installation:

• All nodes except UI, WN and BDII require the host certificate/key files to be installed*
• Contact your national Certification Authority (CA) to understand how to obtain a host certificate if you do not have one already.

Once you have obtained a valid certificate:

• hostcert.pem - containing the machine public key
• hostkey.pem - containing the machine private key

make sure to place the two files in the target node into the /etc/grid-security directory and check the access right for hostkey.pem is only readable by root (0400) and that the public key, hostcert.pem, is readable by everybody (0644).

Check existence

[~]# ls -l /etc/grid-security/hostkey.pem
-r-------- 1 root root 887 Mar 1 17:08 /etc/grid-security/hostkey.pem
[~]# ls -l /etc/grid-security/hostcert.pem
-rw-r--r-- 1 root root 1440 Mar 1 17:08 /etc/grid-security/hostcert.pem

Check expiration

[~]# openssl x509 -in hostcert.pem -noout -dates

Change permission: (if needed)

[~]# chmod 0400 hostkey.pem
[~]# chmod 0600 hostcert.pem

Batch System:

• If you will use LSF (licences are needed) - The server/client installation must be done manually. Have a look to Platform LSF documentation,
• TORQUE server/client installation is done through the use of the -torque- metapackages, see bellow

Access to batch system log files

• through NFS (don't forget to set $BATCH_LOG_DIR and $DGAS_ACCT_DIR in <your-site-info.def> configuration file)
• through a daily cron job to the directory defined in $BATCH_LOG_DIR and $DGAS_ACCT_DIR in <your-site-info.def> configuration file

CAs installation:

• Install CAs on ALL profiles:

yum install ca-policy-egi-core

Middleware installation

• Install the CREAM CE metapackages, containing all packages needed. Have a look to the CREAM CE documentation before starting to install :System Administrator Guide.

# yum install xml-commons-apis 
# yum install emi-cream-ce

Batch System Utilities installation

After the installation of the CREAM CE metapackage it is necessary to install the batch system specific metapackage(s):

• If you are running Torque, and your CREAM CE node is the torque master, install the emi-torque-server and emi-torque-utils metapackages:

# yum install emi-torque-server
# yum install emi-torque-utils

• If you are running Torque, and your CREAM CE node is NOT the torque master, install the emi-torque-utils metapackage:

# yum install emi-torque-utils

IMPORTANT NOTE FOR TORQUE:

After the Torque installation you should have the version 2.5.7-7. Please check that munge is installed and enabled.

# rpm -qa | grep munge
# munge-libs-0.5.8-8.el5
# munge-0.5.8-8.el5

To enable munge on your torque cluster:

• Install the munge package (if it is not installed) on your pbs_server, submission hosts and all worker node hosts in your cluster.
  
• On one host generate a key with /usr/sbin/create-munge-key
  
• Copy the key, /etc/munge/munge.key to your pbs_server, submission hosts and all worker node hosts on your cluster.
  Pay attenction the ownership of that file must be:
  -r-------- 1 munge munge 1024 Jan 03 09:57 munge.key
• Start the munge daemon on these nodes. *service munge start && chkconfig munge on*
  

• If you are running LSF, install the emi-lsf-utils metapackage:
  

     # yum install emi-lsf-utils
     

DGAS_sensors installation & upgrade

Extended Release Notes:

• v. 4.0.13

IGI Release supports the use of DGAS as accounting system - please install also DGAS sensors on the CREAM node:

# yum install igi-dgas_sensors

Upgrade:

• in case of an upgrade from a version < 3 - please follow section 3.1.1.2 Upgrade from a previous release from DGAS Sensors 4.0 guide
• in case of an upgrade from 4.0.x to 4.0.13, after the updated packages are installed just restart the services:
  

     # service dgas-urcollector restart
     # service dgas-pushd restart
     

You can found more documentation at DGAS Sensors 4.0 guide and on DGAS Sensors Service Reference Card

Middleware Configuration

YAIM Verification

• Before starting the configuration PLEASE TEST that you have defined all the mandatory variables for all the CREAM CE profiles.

For Torque:

 /opt/glite/yaim/bin/yaim -v -s <site-info.def> -n  creamCE -n TORQUE_server -n TORQUE_utils -n DGAS_sensors
 

For LSF:

 /opt/glite/yaim/bin/yaim -v -s <site-info.def> -n  creamCE -n LSF_utils -n DGAS_sensors
 

You can find in this documentation: YAIM CREAM CE Variables all mandatory variables.

If no errors are reported with the verification you can proceed to the configuration, otherwise correct them before continuing with the configuration.

Configuration Suggestions:

Blparser:
We suggest to use the new Blparser runs on the CREAM CE machine and it is automatically installed when installing the CREAM CE. The configuration of the new BLAH Blparser is done when configuring the CREAM CE (i.e. it is not necessary to configure the Blparser separately from the CREAM CE).

To use the new BLAH blparser, it is just necessary to set:

BLPARSER_WITH_UPDATER_NOTIFIER=true

ARGUS:
If you have an ARGUS server installed in your site or in central site we suggest to use it. Please set the proper variables:

USE_ARGUS=yes

In this case it is also necessary to set the following yaim variables:

• ARGUS_PEPD_ENDPOINTS The endpoint of the ARGUS box (e.g."https://cream-43.pd.infn.it:8154/authz")
• CREAM_PEPC_RESOURCEID The id of the CREAM CE in the ARGUS box (e.g. "http://pd.infn.it/cream-18")

If instead gJAF should be used as authorization system, yaim variable USE_ARGUS must be set in the following way:

USE_ARGUS=no

DGAS_sensors: For DGAS_sensors you should customize the services file. You can find in this path an example:

 /opt/glite/yaim/examples/siteinfo/services/dgas_sensors 

YAIM Configuration

Please use the debug flag ( "-d 6") to configure the services in order to have detailed information. For your convenience yo can save all the configuration information in a log file you can look at any time, separated from the yaimlog default one.

IMPORTANT NOTE:
For Torque was found an error in starting pbs_server so if you are configuring the PBS server NODE before launching yaim remember to start pbs_server:

/etc/init.d/pbs_server start

For Torque:

# /opt/glite/yaim/bin/yaim -c -d 6 -s  <site-info.def>  -n  creamCE -n TORQUE_server -n TORQUE_utils -n DGAS_sensors 2>&1 | tee /root/conf_CREAM_Torque_DGAS.`hostname -s`.`date +%Y-%m-%d-%H-%M-%S`.log

For LSF:

# /opt/glite/yaim/bin/yaim -c -d 6 -s  <site-info.def>  -n  creamCE -n LSF_utils -n DGAS_sensors 2>&1 | tee /root/conf_CREAM_LSF_DGAS.`hostname -s`.`date +%Y-%m-%d-%H-%M-%S`.log

IMPORTANT NOTE FOR TORQUE:
After the Torque installation you should have the version 2.5.7-7 (SL5) or 2.5.7-9 (SL5) Please remember to copy the munge key from the batch master to the WN just installed # scp <batch master host>:/etc/munge/munge.key /etc/munge For more details please read Deployment Notes of TORQUE WN config - it applies to all versions >= 2.5.7-1

Service Configuration

YAIM Verification

• Before starting the configuration PLEASE TEST that you have defined all the mandatory variables for all the WN profiles (WN_torque, WN_torque_noafs, WN_LSF, WN_LSF_noafs)

• For Torque:
  

  # /opt/glite/yaim/bin/yaim -v -s <your-site-info.def> -n  WN_torque 

  or

  # /glite/yaim/bin/yaim -v -s <your-site-info.def> -n  WN_torque_noafs 

• For LSF:
  

  # /opt/glite/yaim/bin/yaim -v -s <your-site-info.def> -n  WN_LSF

  or

  # /opt/glite/yaim/bin/yaim -v -s <your-site-info.def> -n  WN_LSF_noafs

• For Other Batch System:
  

  # /opt/glite/yaim/bin/yaim -v -s <your-site-info.def> -n  WN

You can find all mandatory variables in this documentation: YAIM WN Variables

If no errors are reported during verification you can proceed with the configuration, otherwise correct them before continuing.

YAIM Configuration

• Please use the debug flag ( "-d 6") to configure the services in order to have detailed information.
• For your convenience you can save all the configuration information in a log file for each configuration separately, different from the default yaimlog, that contins all the history of all configurations.

• For Torque:
  

   # /opt/glite/yaim/bin/yaim -c -d 6 -s  <your-site-info.def>  -n  WN_torque 2>&1 | tee /root/conf_WN_torque.`hostname -s`.`date +%Y-%m-%d-%H-%M-%S`.log

  or

   # /opt/glite/yaim/bin/yaim -c -d 6 -s  <your-site-info.def>  -n  WN_torque_noafs 2>&1 | tee /root/conf_WN_torque_noafs.`hostname -s`.`date +%Y-%m-%d-%H-%M-%S`.log

 WARNING: /var/lib/torque/mom_priv/config already exists, YAIM will not touch it
 WARNING: Batch server defined in BATCH_SERVER variable is different 
 WARNING: from the batch server defined under /var/lib/torque/mom_priv/config
 WARNING: Remove /var/lib/torque/mom_priv/config and reconfigure again to use the new value! 

• For LSF:
  

   # /opt/glite/yaim/bin/yaim -c -d 6 -s  <your-site-info.def> -n  WN_LSF 2>&1 | tee /root/conf_WN_LSF`.hostname -s`.`date +%Y-%m-%d-%H-%M-%S`.log

  or

• For Other Batch System:

 /opt/glite/yaim/bin/yaim -c -d 6 -s    -n  WN 2>&1 | tee /root/conf_WN.`hostname -s`.`date +%Y-%m-%d-%H-%M-%S`.log

Known Issues

• ig_WN SL6 version:
  • misses the dependency on HEP_OSLib, available from linuxsoft/wlcg. One has to install the latest version available there.
  • in SL6 there is no portmap daemon. It should be replaced with rpcbind in the yaim configuration function config_nfs_sw_dir_client. It should be fixed in a future version of the yaim-addons package.

HLR Server Installation and Configuration NEW Update

Extended Release Notes:

• v. 4.0.15
• v. 4.0.13

HLR Prerequisites

Hardware Requirements

• The HLR Server host should be a real or virtual node having an optimal disk access.
• The suggested requirements are:
  • CPU: 4/8 cores
  • Memory: 8/16GB RAM
  • Disk: minimum 200 GB of space for a first level HLR. (if you have an old HLR server please check your database actual dimension and redouble the partition size)
  • Network: open port TCP 56568 for inbuond connectivity

Co-Hosting

• Due to its critical nature the HLR Server should be installed as a stand-alone service.

Virtual vs. Physical

• If you will use a virtual host ensure you are not using Virtio to access to the mysql storage DB.
• Please use a physical disk partition for the filesystem hosting the DB

Operating System

• HLR Server 4.0 is supported on Scientific Linux 5, x86_64 and Scientific Linux 5, x86_64

Host certificate installation:

• The HLR host must be configured with X.509 certificates signed by a trusted Certification Authority (CA).
• The hostcert.pem and hostkey.pem certificates are located in the /etc/grid-security/ directory, and they must have permission 0644 and 0400 respectively:
• Check existence
  

     # ls -l /etc/grid-security/hostkey.pem
     -r-------- 1 root root 887 Mar 1 17:08 /etc/grid-security/hostkey.pem
     # ls -l /etc/grid-security/hostcert.pem
     -rw-r--r-- 1 root root 1440 Mar 1 17:08 /etc/grid-security/hostcert.pem
     

• Check expiration
  

  [~]# openssl x509 -in hostcert.pem -noout -dates

• Change permission: (if needed)
  

     # chmod 0400 hostkey.pem
     # chmod 0600 hostcert.pem
     

Middleware Installation

• Have a look to the section Repository Settings and ensure that you have the common repo files.
• You can use any of the group of repositories reccomended for SL5/x86_64 (EMI 1 or EMI 2) section or SL6/x86_64 (EMI 2) section.
• Before starting the installation procedure remember to clean all yum cache and headers:
  

  # yum clean all

CAs installation:

• Install CAs on ALL profiles:
  

  # yum install ca-policy-egi-core

HLR Server installation

• Have a look to the HLR documentation before starting the installation: HLR Server 4.0 Guide.
• Install the HLR metapackages, containing all packages needed:
  

  # yum install igi-hlr

Middleware Configuration

Verification

• Before starting the configuration PLEASE TEST that you have defined all the mandatory variables for all the HLR profile
  

  # /opt/glite/yaim/bin/yaim -v -s <your-site-info.def> -n  HLR 

• If no errors are reported during verification you can proceed to the configuration, otherwise correct them before continuing.

HLR Server Configuration

• Please use the debug flag ( "-d 6") to configure the services in order to have detailed information.
• For your convenience you can save all the configuration information in a log file for each configuration separately, different from the default yaimlog, that contins all the history of all configurations.
  

   # /opt/glite/yaim/bin/yaim -c -d 6 -s  <site-info.def>  -n  HLR 2>&1 | tee /root/conf_igi-HLR.`hostname -s`.`date +%Y-%m-%d-%H-%M-%S`.log

Known Issue - IMPORTANT NOTE

After configuration please change into the file /etc/cron.d/dgas the command from /usr/sbin/dgas-hlr-translatedb to /usr/sbin/dgas-hlr-populateJobTransSummary like the example below:

cat /etc/cron.d/dgas 
# Cron file created by YAIM - don't modify it!
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/

# Update hlr database
*/4 * * * * root /usr/sbin/dgas-hlr-populateJobTransSummary > /dev/null 2>&1

This fix will be provide with the new yaim in next release.

Post installation and configuration

• After the installation and configuration of the HLR Server services, you should register all the resources of the CEs attached to your HLR Server. Please use thecommand below for each CE:
  

  # dgas-hlr-addadmin -Sa  <CE_DN>

• Where <CE_DN> is something like "/C=IT/O=INFN/OU=Host/L=Padova/CN=prod-ce-01.pd.infn.it"

Update From a previous release < 4.0:

• IMPORTANT NOTE: some of the operations described bellow (like "translate DB", the start of hlrd or "populateJobTransSummary") can take a lot of time, from minutes to hours or days (!) depending on how big the DB is. Please plan carefully an upgrade!

• Back up the old databases :
  • on HLR Server stop the dgas services and make a dump of the databases:
    • Stop the services :
      

      # /etc/init.d/glite-dgas-hlrd stop 

    • Check disk space
      • Ensure you have enough space in the disk:
        

        # df -h

      • You should have the space to contain the hlr and hlr_tmp database dump. (Mount an external partition or NFS partition if you don't have enough free space)
    • Make the dump :
      

               mysqldump --user=root --password hlr > /data/hlr.sql
               mysqldump --user=root --password hlr_tmp > /data/hlr_tmp.sql
               

• Installation :
  • Install again the host with SL5 or SL6, x86_64 distribution or install a new host where the HLR Server will be installed.
  • Following the instructions in the previous section install the HLR Server and configure it using yaim.
• Stop the HLR server process:
  

  # /etc/init.d/dgas-hlrd stop

• Restore the dump :
  

     # mysql -u root -p hlr_tmp < /data/hlr_tmp.sql
     # mysql -u root -p hlr < /data/hlr.sql
     

• execute translate DB
  

  # nohup /usr/sbin/dgas-hlr-translatedb -D & 

• Start dgas services :
  

  # /etc/init.d/dgas-hlrd start 

• Execute populateJobTransSummary:
  • The new HLR version need to polulate the JobTransSummary
    

    # /usr/sbin/dgas-hlr-populateJobTransSummary 

• Restart dgas services :
  

  # /etc/init.d/dgas-hlrd restart 

• Change the into the file */etc/cron.d/dgas the command from /usr/sbin/dgas-hlr-translatedb to /usr/sbin/dgas-hlr-populateJobTransSummary

Post Update Procedure

After the update of the HLR Server , you should register again all the resources of the CE attached to your HLR Server. Please use this command below for each CE:

# dgas-hlr-addadmin -Sa  <CE_DN>

Where <CE_DN> is something like "/C=IT/O=INFN/OU=Host/L=Padova/CN=prod-ce-01.pd.infn.it"

Update From a previous release >= 4.0.13:

• Just update the packages:
  

  # yum update
