---+ IGI (based on gLite 3.2) Installation and Configuration
---++ 
---++ *Installation*
---+++ OS installation

Install SL5 using [[href="http://linuxsoft.cern.ch/scientific/5x/][ SL5.X repository (CERN mirror)]] or one of the supported <acronym title="Operating System">OS</acronym> (RHEL5 clones).

You may find information on official repositories at [[href="http://igrelease.forge.cnaf.infn.it/doku.php?id=doc:tips:repos][Repositories for APT and YUM]] <br /> If you want to set up a local installation server please refer to [[http://igrelease.forge.cnaf.infn.it/doku.php?id=doc:tips:mrepo][Mrepo Quick Guide]]

*NOTE*: Please check if <em> =NTP= </em>, <em> =cron= </em> and <em> =logrotate= </em> are installed, otherwise install them!

---++++ Check the FQDN hostname

Ensure that the hostnames of your machines are correctly set. Run the command:
<pre> hostname -f</pre>

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 [[http://wiki.italiangrid.org/twiki/bin/view/IGIRelease/RepositoriesSpecifications][Repository Specifications]]

With standard installation of SL5 it's possible that you have the EPEL repository enabled. Please disable it:
<pre># mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.disabled
</pre>

otherwise you'll get the following error:
<pre>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)
</pre>

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** |
| [[http://repo-pd.italiangrid.it/mrepo/repos/sl5/x86_64/dag.repo][dag.repo]] |
| [[http://repo-pd.italiangrid.it/mrepo/repos/sl5/x86_64/ig.repo][ig.repo]] |
| [[http://repo-pd.italiangrid.it/mrepo/repos/sl5/x86_64/egi-trustanchors.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:

Then update your host:
<pre>yum clean all
</pre>

---+++ CAa installation:

Install CAs on ALL profiles:
<pre>yum install ca-policy-egi-core
</pre>

---+++ Metapackage installation

Please consider that x86_64 WN profiles has to be installed using the &ldquo;groupinstall&rdquo; yum command as follows:
<pre> yum groupinstall &lt;WN_profile&gt;  </pre>

where &lt;WN_profile&gt; could be one of: ig_WN, ig_WN_noafs, ig_WN_torque, ig_WN_torque_noafs, ig_WN_LSF, ig_WN_LSF_noafs or
<pre> yum groupinstall &lt;UI_profile&gt;  </pre>

where &lt;UI_profile&gt; could be one of: ig_UI, ig_UI_noafs

If you are installing any othere profiles use:
<pre> yum install &lt;metapackage&gt; </pre>

Where =&lt;metapackage&gt;= is one of those reported on the table above ( _Metapackages_ column).

To have more details to the repository have a look to the this link [[http://wiki.italiangrid.org/twiki/bin/view/IGIRelease/RepositoriesSpecifications][Repository Specifications]]

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

 You need to have enabled only the above repositories (Operating System, EPEL, Certification Authority, EMI):
| *Common repositories *x86_64** |
| [[http://repo-pd.italiangrid.it/mrepo/repos/emi/sl5/x86_64/epel.repo][epel.repo]] |
