Configure SQUID in /etc/squid/squid.conf with:
# squid listen ports http_port 3128 # set up file system (use aufs or ufs) and directory for caching files, 50000 is disk space in MB which can be used for caching files. cache_dir aufs /var/spool/squid 50000 16 256 # maximum object size maximum_object_size 4096 MB # memory cache cache_mem 4096 MB # Add your local network to your ACLs and other rights depend on your security level. At least to give access for cvmfs clients. acl local_net src network_addr/mask_addr http_access allow local_net
wget http://cvmrepo.web.cern.ch/cvmrepo/yum/cernvm.repo -O /etc/yum.repos.d/cernvm.repo yum install -y cvmfs-keys cvmfs cvmfs-init-scripts
Create directory on local disk where CVMFS client will store data.
mkdir /scr/cvmfs
Edit /etc/cvmfs/default.local. Define some variables:
CVMFS_REPOSITORIES - repositories to include, like atlas.cern.ch or cms.cern.ch.
CVMFS_HTTP_PROXY - URL of your SQUID server
CVMFS_CACHE_BASE - path to data dir
CVMFS_QUOTA_LIMIT - maximum size in MB for cached data. (see http://cernvm.cern.ch/portal/cvmfs/examples)
Bellow is config file we use at ISMA for Belle.
CVMFS_REPOSITORIES=belle.cern.ch CVMFS_HTTP_PROXY=http://wwproxy.grid.isma:3128 CVMFS_CACHE_BASE=/scr/cvmfs CVMFS_QUOTA_LIMIT=2000
Add line to /etc/fstab
belle.cern.ch /cvmfs/belle.cern.ch cvmfs ro
Start service
service cvmfs start
Mount FS
mkdir -p /cvmfs/belle.cern.ch mount -a -t cvmfs
Try ls -l /cvmfs/belle.cern.ch - it should work.
