# /etc/init.d/httpd restart

# adduser argo

# cvmfs_server mkfs  argo

Before you can install anything, call `cvmfs_server transaction`
to enable write access on your repository. Then install your
software in /cvmfs/argo. as user argo.
Once you're happy, publish using `cvmfs_server publish`

For client configuration, have a look at 'cvmfs_server info'

If you go for production, backup you software signing keys in /etc/cvmfs/keys/!

#  cvmfs_server transaction

#  ls  /cvmfs/
argo.

  • Increase ulimit adding
