Robs DiracServer Install Guide
This is a WIP guide for setting up a server version of DIRAC mainly for testing/development when install scripts aren't being your friend. (This is also a training exercise to make sure I know how things tie together)
I'm assuming that you're installing DIRAC into: /opt/dirac/DIRAC and that you've followed other tutorials on how to ensure your system is compatible and you have the required pre-requisits
Contents
Get DIRAC
Firstly lets grab DIRAC and any extra modules you want and put them in place:
git clone DIRAC and switch to the branch we're interested in (the latest in the v6r12 series here):
git clone https://github.com/ic-hep/DIRAC.git /opt/dirac/DIRAC git --git-dir=/opt/dirac/DIRAC/.git --work-tree=/opt/dirac/DIRAC checkout rel-v6r12 /opt/dirac/DIRAC/Core/scripts/dirac-deploy-scripts.py
The final line here deploys the scripts used by DIRAC which will become useful later on and creates a useful .bashrc
Web interface (optional but highly recommended)
git --git-dir=/opt/dirac/Web/.git --work-tree=/opt/dirac/Web checkout v1r3p7
GridPPDIRAC extensions
git clone https://github.com/ic-hep/GridPPDIRAC.git /opt/dirac/GridPPDIRAC git --git-dir=/opt/dirac/GridPPDIRAC/.git --work-tree=/opt/dirac/GridPPDIRAC checkout master
Setup Grid Certificates
Create the folder:
mkdir -p /opt/dirac/etc/grid-security
and copy your hostcert.pem and hostkey.pem to this folder and make the following symlinks:
ln -sf /etc/grid-security/certificates /opt/dirac/etc/grid-security/certificates ln -sf /etc/grid-security/vomsdir /opt/dirac/etc/grid-security/vomsdir
or, configure your certificates to be installed in this directory.
Run install script
You now need to create a config file which will be used to install DIRAC:
LocalInstallation

}
Setting Up the external Dependencies
The external dependencies are often troublesome/time-consuming to compile as it requires compiling static versions of very large projects and is often fought with difficulties.
It is heavily recommended to just install the version which has been provided by the DIRAC developers.
For our example the latest externals correspond to the ones available through the v6r12p32. version6 release12 patch32
The dirac-install script doesn't always determine the latest patch-level correctly and would pull in the Externals corresponding to v6r12p0.
/opt/dirac/scripts/dirac-install -t server -B -X -r v6r12p32 /opt/dirac/etc/dinstall.cfg
