Virgo CVMFS client installation instructions

1. Client installation

The Virgo CVMFS client is the same software which is packed with the standard CVMFS distribution. In order to get a functional environment please follow the official CVMFS documentation found at link, up to the (experiment-specific) steps requiring creating and editing of the default.local file.

2. Public keys installation

The public keys needed for the access to the virgo.ego-gw.it CVMFS repository can be installed using this .rpm package contained in this repo at link. Download the linked file and install it via:

	rpm -i <path-to-the-rpm-file>/cvmfs-virgo.ego-gw.it-pub-key.rpm

The installed keys can be found at /etc/cvmfs/keys/virgo.ego-gw.it.pub.

To uninstall them it is enough to run:

	rpm -e cvmfs-virgo.ego-gw.it-pub-key

3. Virgo specific settings

Once the CVMFS client and the public keys .rpm have been correctly installed one can proceed with the creation of the file /etc/cvmfs/config.d/virgo.ego-gw.it.local.

The file must include several lines:

1. CVMFS_SERVER_URL=http://cvmfs-virgo.cr.cnaf.infn.it/cvmfs/virgo.ego-gw.it: to define the CNAF stratum-1 endpoint
2. CVMFS_PUBLIC_KEY=/etc/cvmfs/keys/virgo.ego-gw.it.pub: to point to the public keys installed with the .rpm
3. CVMFS_HTTP_PROXY="http://local.proxy:port": to specify the local proxy to be used. Note that for machines external to a CC, hence not backed with a proxy, the option "|DIRECT" can be appended to connect to the stratum-1 directly.

4. Test

In order to test the setup and automatically mount the configured repository, please perform the following operations.

# cvmfs_config setup
# cvmfs_config chksetup
OK
# service autofs restart
Redirecting to /bin/systemctl restart autofs.service
# cvmfs_config probe virgo.ego-gw.it
Probing /cvmfs/virgo.ego-gw.it... OK

At that point you should be able to perform an ls of the repo mountpoint obtaining similar output:

# ls /cvmfs/virgo.ego-gw.it/
