IGI Installation and Configuration Guide for gLite 3.2 SL5 x86_64

This document is a complete guide for the installation and the configuration of INFNGRID profiles aligned with gLite middleware version 3.2 on SL5 (or RHEL5 clones) for x86_64 architecture (no i386 profiles have been deployed up to now).

Currently only few profiles have been ported to SL5 x86_64 and integrated in INFNGRID release. At the following link you can find the current status of gLite and INFNGRID porting:

If you find errors in this document please open a ticket to the "Release & Documentation" group using the INFNGRID trouble ticketing system.

Released profiles:

IMPORTANT NOTE: Please be aware that the profile ig_GRIDFTP is obsoleted by the ig_SE_storm_gridftp, and an updgrade is not possible, only fresh installations of the ig_SE_storm_gridftp

Here below an updated lists of currently deployed profiles with related metapackage and nodetype names:

Please keep in mind the difference between the following three concepts because of their different scopes and uses:

  • profile => we use this word to //generically// call a service
  • metapackage => we use this word during //installation// phase
  • nodetype => we use this word during //configuration// phase

Please also refer to these gLite official guides:

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 repositories at [http://igrelease.forge.cnaf.infn.it/doku.php?id=doc:tips:repos][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).

Repository Settings

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

With standard installation of SL5 it's possible that you have the EPEL repository enabled. Please disable it:

# mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.disabled

otherwise you'll get the following error:

Missing Dependency: libcares.so.0()(64bit) is needed by package glite-security-gss-2.0.0-3.sl5.x86_64 (glite-generic_sl5_x86_64_release)

because of the presence of newer version of c-ares (1.4.0-1.el5). The middleware needs the 1.3.0-4.sl5 !

Remeber to enabled the dag.repo :

With standard installation of SL5 it's possible that you have the DAG repository. Please check if it is enabled, if no please enabled it:

cat /etc/yum.repos.d/dag.repo

.... enabled=1 ....

Common repositories

Each profile needs a set of common repositories:

Common repositories *x86_64*
dag.repo
ig.repo
egi-trustanchors.repo

In order to have a working IGI service you have to download also the gLite repo files. In the table bellow you'll find the match from metapackages to profiles.

Profile-specific repositories

Furthermore each profile needs a set of repositories that contain the profile-related middleware. Look at the table below to know what specific repositories your profile needs:

Metapackages Profile-specific repositories *x86_64*
ig_ARGUS glite-argus.repo
ig_BDII_top glite-bdii_top.repo
ig_BDII_site glite-bdii_site.repo
ig_CREAM
ig_CREAM_LSF
glite-cream.repo
ig_CREAM_torque glite-cream_torque.repo
ig_FTA_oracle glite-fta_oracle.repo
ig_FTM glite-ftm.repo

ig_WN, ig_WN_noafs
ig_WN_LSF, ig_WN_LSF_noafs
glite-wn.repo
ig_WN_torque, ig_WN_torque_noafs glite-wn_torque.repo

Then update your host:

yum clean all

CAa installation:

Install CAs on ALL profiles:

yum install ca-policy-egi-core

Metapackage installation

Please consider that x86_64 WN profiles has to be installed using the “groupinstall” yum command as follows:

 yum groupinstall <WN_profile>  

where <WN_profile> could be one of: ig_WN, ig_WN_noafs, ig_WN_torque, ig_WN_torque_noafs, ig_WN_LSF, ig_WN_LSF_noafs or

 yum groupinstall <UI_profile>  

where <UI_profile> could be one of: ig_UI, ig_UI_noafs

If you are installing any othere profiles use:

 yum install <metapackage> 

Where <metapackage> is one of those reported on the table above ( Metapackages column).

IMPORTANT NOTE: When you are installing ig_CREAM or ig_CREAM_LSF or ig_CREAM_torque adding an exclude line to the .repo file, e.g. in /etc/yum.repos.d/slc5-updates.repo or /etc/yum.repos.d/sl5-security.repo

exclude=c-ares

Special cases

CE and Batch Server configuration (access to log files)

It doesn't matter what kind of deployment you have, batch-system master on a different machine than the CE (CREAM, TORQUE or LSF) or on the same one, you have to be sure that you provide access to the batch system log files: You must set up a mechanism to ''transfer'' accounting logs to the CE:

  • 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

CREAM_torque (multiple CEs and single Batch Server)

This configuration requires particular attention both during the metapackage installation and during the nodetype configuration.

Install the first CE (that will act also as Batch Server) following the usual procedure:

yum install ig_CREAM_torque

Install the other secondary CEs without batch server software as follows:

yum install ig_CREAM glite-TORQUE_utils

Standalone TORQUE_server

You should use the following .repo files, glite-torque_server.repo & glite-torque_utils.repo

yum install glite-TORQUE_server glite-TORQUE_utils

for the CEs (creamCEs), add the glite-torque_utils.repo file and:

yum install ig_CREAM glite-TORQUE_utils

Please pay attention also to the configuration for this special case

Batch system installation (only for WN)

LSF server/client installation must be done *manually*, whereas Torque server/client installation is included in the metapackage.

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 Scope Details
<your-site-info.def> whole-site 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 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: Whole site: How to create local users.conf and configure users.
<your-groups.conf> whole-site 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.

Additional files

Furthermore the configuration folder can contain:

Directory Scope Details
services/ service-specific It contains a file per nodetype with the name format: ig-node-type.
The file contains a list of configuration variables specific to that nodetype.
Each yaim module distributes a configuration file in =/opt/glite/yaim/examples/siteinfo/services/[ig or glite]-node-type.
It's a mandatory directory if required by the profile and you should copy it under the same directory where <your-site-info.def> is.
 
nodes/ host-specific It contains a file per host with the name format: hostname.domainname.
The file contains host specific variables that are different from one host to another in a certain site.
It's an optional directory.
vo.d/ VO-specific It contains a file per VO with the name format: vo_name, but most of VO settings are still placed in ig-site-info.def template. For example, for ”lights.infn.it”:
# 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"

It's an optional directory for “normal” VOs (like atlas, alice, babar), mandatory only for “fqdn-like” VOs. In case you support such VOs you should copy the structure vo.d/<vo.specific.file> under the same directory where <your-site-info.def> is.

group.d/ VO-specific It contains a file per VO with the name format: groups-<vo_name>.conf.
The file contains VO specific groups and it replaces the former <your-groups.conf> file where all the VO groups were specified all together.
It's an optional directory.

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

IMPORTANT NOTE:
If your site has the intention to support more VOs than the default ones, you should have a look at Whole site: How to enable a VO, specially for the enmr.eu VO, once the configuration finished you should follow "extra_configuration".

Default files

Variables that contain a meaningful default value are distributed under ''/opt/glite/yaim/defaults/'' directory and that don't need to be changed unless you are an advanced user and you know what you are doing. The files are:

  • ''ig-site-info.pre'';
  • ''ig-site-info.post'';
  • ''<node-type>.pre'', ''glite-<node-type>.pre'', ''ig-<node-type>.pre'';
  • ''<node-type>.post'', ''glite-<node-type>.post'', ''ig-<node-type>.post''.

In case you really need to change these variables, you don't need to modify the value in these files if you don't want to edit them. You can just add the same variable in site-info.def since this will overwrite the variables declared in these files. See the configuration flow in YAIM in the next section.

Configuration flow

This is the order in which the different configuration files are sourced (''<confdir>'' refers to the path of the configuration folder which is the path of ''<your-site-info.def>''):

  1. defaults ''.pre'' files in ''/opt/glite/yaim/defaults/'';
  2. ''<confdir>/<your-site-info.def>'';
  3. service-specific files in ''<confdir>/services/'';
  4. defaults ''.post'' files in ''/opt/glite/yaim/defaults/'';
  5. node-specific files in ''<confdir>/nodes/'';
  6. VO-specific files in ''<confdir>/vo.d/'';
  7. function files in ''/opt/glite/yaim/node-info.d/'';
  8. VO-specific group settings in ''<confdir>/group.d/*''.

Configuration variabiles

General

In the documentation you could find all the INFNGRID variables and some important gLite variables that can be configured in ''<your-site-info.def>'' are listed in alphabetically sorting (links to gLite variables are also listed):

  • C = compulsory, if you are going to configure that type of node;
  • O = optional.

For the other gLite variables please consider the official "site-info.def" information at "YAIM 4 guide for sysadmins".

[configuration]
EGI = FALSE
OSG = FALSE
manual = True
manual_file = /opt/glite/yaim/config/>file_containing_your_sites.conf>
output_file = /opt/glite/etc/gip/top-urls.conf
cache_dir = /var/cache/glite/glite-info-update-endpoints 

The file containing the list of sites "known" to the BDII_top is updated every hour by the cron-job /etc/cron.hourly/glite-info-update-endpoints.

CREAM CE

Configuration file:

Specific variables are in:

  • ''/opt/glite/yaim/examples/siteinfo/services/glite-creamce''

Please copy and edit that file in your ''/services'' directory (have a look to Yaim configuration files").

Variable name Type Descpription >= ig-yaim version
ACCESS_BY_DOMAIN C By default the cream db is installed on localhost and accessible only from localhost. Setting ACCESS_BY_DOMAIN to true, you allow the cream db to be accessed from all computers in your domain. >= 4.0.5-4
BATCH_CONF_DIR C LSF settings: path where lsf.conf is located >= 4.0.5-4
BLAH_JOBID_PREFIX C This parameter sets the BLAH jobId prefix (it MUST be 6 chars long, begin with cr and terminate by '_'). It is important in case of more than one CE connecting to the same blparser. In this case, it is better that each CREAM_CE has its own prefix. The default value for this variable (as specified in opt/glite/yaim/defaults/glite-creamce.pre) is "cream_" >= 4.0.5-4
BLPARSER_HOST C to refer to the host where the Blah Log Parser is running or where the blparser is running (i.e. the variable xxx_BLPserver of blah.config). In this machine batch system logs must be accessible >= 4.0.5-4
BLP_PORT C to refer to the the port where Blah Log Parser is running (i.e. the variable xxx_BLPport of blah.config, GLITE_CE_BLPARSERxxx_PORT1 of blparser.conf) >= 4.0.5-4
CREAM_CE_STATE C This is the value to be published as GlueCEStateStatus instead of Production. The default value for this variable (as specified in opt/glite/yaim/defaults/glite-creamce.pre) is "Special" >= 4.0.5-4
CREAM_DB_USER C Database user to access cream database (different by root). Yaim will create this user and grant him the access rights >= 4.0.5-4
CEMON_HOST O Cream CE host name. In a more complex layout, the ce-monitor can be installed in a host different from the cream-ce host. In that case you need to put the right ce-monitor hostname in this variable. >= 4.0.5-4
CREAM_PORT C to refer to the parser listening cream port (i.e. the variable GLITE_CE_BLPARSERxxx_CREAMPORT1 of blparser.conf) >= 4.0.5-4
JOB_MANAGER C The name of the job manager used by the gatekeeper. For CREAM please define: pbs, lsf, sge or condor >= 3.0.1-0

DGAS services on CE ( CE CREAM )

Variable name Type Descpription >= ig-yaim version
''DGAS_ACCT_DIR'' C Path for the batch-system log files.
- for torque/pbs:
DGAS_ACCT_DIR=/var/torque/server_priv/accounting
- for LSF:
DGAS_ACCT_DIR=lsf_install_path/work/cluster_name/logdir
4.0.8-3
''DGAS_IGNORE_JOBS_LOGGED_BEFORE'' O Bound date on jobs backward processing.
The backward processing doesn't consider jobs prior to that date.
Use the format as in this example:
DGAS_IGNORE_JOBS_LOGGED_BEFORE="2007-01-01"
Default value: ''2008-01-01''
4.0.2-9
''DGAS_JOBS_TO_PROCESS'' O Specify the type of job which the CE has to process.
ATTENTION: set "all" on "the main CE" of the site (the one with the best hardware), "grid" on the others.
Default value: ''all''
4.0.2-9
''DGAS_HLR_RESOURCE'' C Reference Resource HLR hostname. There is no need to specify the port as in the previous yaim versions (default value "''56568''" will be set by yaim). 4.0.2-9
''DGAS_USE_CE_HOSTNAME'' O Only for LSF. Main CE of the site.
ATTENTION: set this variable only in the case of site with a single LSF Batch Master (no need to set this variable in the Torque case) in which there are more than one CEs or local submission hosts (i.e. host from which you may submit jobs directly to the batch system.).
In this case, ''DGAS_USE_CE_HOSTNAME'' parameter must be set to the same value for all hosts sharing the "lrms" and this value can be arbitrary chosen among these submitting hostnames (you may choose the best one).
Otherwise leave it commented.
For example:
DGAS_USE_CE_HOSTNAME="my-ce.my-domain"
4.0.2-9
''DGAS_MAIN_POLL_INTERVAL'' O UR Box parse interval, that is if all jobs have been processed: seconds to wait before looking for new jobs in UR Box. default value "5" 4.0.11-4
''DGAS_JOB_PER_TIME_INTERVAL'' O Number of jobs to process at each processing step (several steps per mainPollInterval, depending on the number of jobs found in chocolateBox). default value "40" 4.0.11-4
''DGAS_TIME_INTERVAL'' O Time in seconds to sleep after each processing step (if there are still jobs to process, otherwise start a new mainPollInterval). default value "3" 4.0.11-4
''DGAS_QUEUE_POLL_INTERVAL'' O Garbage clean-up interval in seconds. default value "2" 4.0.11-4
''DGAS_SYSTEM_LOG_LEVEL'' O The "systemLogLevel" parameter defines the log verbosity from 0(no logging) to 9(maximum Verbosity) default value "7" 4.0.11-4

FTS

GLEXEC_wn

Functional Description:

  • The gLExec system, used in combination with the LCAS site-local authorization system and the LCMAPS local credential mapping service, provides an integrated solution for site access control to grid resources. With the introduction of gLExec, the submission model can be extended from the traditional gatekeeper models, where authorization and credential mapping only take place at the site’s ‘edge’. Retaining consistency in access control, gLExec allows a larger variety of job submission and management scenarios that include per-VO schedulers on the site and the late binding of workload to job slots in a scenario where gLExec in invoked by pilot jobs on the worker node. But it is also the mapping ingredient of a new generation of resource access services, like CREAM.
