DIRAC Operations Tutorial

Plan of the tutorial

In VirtualBox Preferences -> Network -> Host-only Networks add vboxnet0 interface
Import SLC6_tutorial_0.4.ova VM image (http://diracgrid.org/files/tutorial/SLC6_tutorial_0.4.ova)
In VM Settings General -> Advanced set Shared Clipboard and Drag'n'drop to bidirectional
In VM Settings Network Adapter 1 set to NAT, Adapter 2 set to Host-only Adapter Name: vboxnet0
In VM Settings Shared Folders it can be convenient to define one shared folder

Start the VM and login as root, the su dirac
Check the host accessibility by ssh:

$ ifconfig

Note the IP address of the eth1 interface, e.g. 192.168.56.101 From the host terminal do:

$ ssh [email protected]

Edit /etc/hosts. Add

192.168.56.101 dirac.cern.ch dirac
Remove firewall restrictions in the VM - run as root:

$ system-config-firewall-tui
Follow instructions in /home/dirac/Tutorial/README file to prepare the host
Copy generated CA certificates to /opt/dirac/etc/grid-security/certificates
Copy generated host certificates to /opt/dirac/etc/grid-security
Do:

$ export X509_CERT_DIR=/opt/dirac/etc/grid-security/certificates
Hint: make a copy of the resulting /opt/dirac directory. If something goes wrong it will help to restart from this point.

Edit install_minimal.cfg configuration file
Install minimal set of the DIRAC services with:

$ ./install_site install_minimal.cfg

Hint: Populate /opt/dirac/.installCache with files in /home/dirac/Externals
Install /opt/dirac/sbin/runsvdir-start script
Make DIRAC services start at boot time. Add file /etc/init/dirac.conf containing:

start on runlevel [123456] stop on runlevel [0]

respawn exec /opt/dirac/sbin/runsvdir-start
Reboot the VM
