NFS Network File System C / S // more suitable for local area network,
rpc 111 remote procedure call mechanism
S: set up a shared directory
C: Mount the use of the shared directory mount

Installation yum -y install nfs-utils rpcbind
Establishing a mount point [root @ yum ~] # mkdir / data
Edit [root @ yum ~] # vim / etc / exports

Installation [root @ www ~] # yum -y install nfs-utils
