Imperial Dirac server

Prerequisites

• A host machine with SL6.
• >2GB free in /opt.
• A host certificate.
• No mysql or mysql-libs package on the machine (/etc/my.cnf conflicts with dirac settings).
• A link to the documentation.
• Sign up with the diracgrid-forum.

Now you need to work out which version to install; this can be found in the tags list on GitHub.

Installing the server

Following the steps here to some degree.

[root ~]# wget http://repository.egi.eu/sw/production/cas/1/current/repo-files/EGI-trustanchors.repo -O /etc/yum.repos.d/EGI-trustanchors.repo
[root ~]# yum install ca-policy-egi-core
[root ~]# useradd -s /bin/bash -d /home/dirac dirac
[root ~]# mkdir -p /opt/dirac/etc/grid-security/
[root ~]# cp /etc/grid-security/host*.pem /opt/dirac/etc/grid-security
[root ~]# chown -R dirac:dirac /opt/dirac
[root ~]# su - dirac
[dirac ~]$ ln -s /etc/grid-security/certificates  /opt/dirac/etc/grid-security/certificates
[dirac ~]$ mkdir ~/DIRAC
[dirac ~]$ cd ~/DIRAC
[dirac DIRAC]$ wget https://github.com/DIRACGrid/DIRAC/raw/integration/Core/scripts/install_site.sh

This is the initial preparation done, the next steps actually install the server components.

# This step takes quite a while (~10 minutes)
[dirac DIRAC]$ ./install_site.sh full.cfg
# Eventually it fails with a python error ending with: Requirement.parse('WebOb>=1.2'))
# Edit /opt/dirac/versions/v6r11p8_1407412493/Linux_x86_64_glibc-2.12/lib/python2.6/site-packages/WebTest-2.0.14-py2.6.egg/EGG-INFO/requires.txt to erase the WebOb line.
# Then start it again...
[dirac DIRAC]$ ./install_site.sh full.cfg
