NFS：

[root@nfs-server ~]# yum -y install nfs-utils rpcbind
[root@nfs-client ~]# yum -y install nfs-utils rpcbind
[root@nfs-server ~]# mkdir -p /opt/test
[root@nfs-server ~]# ll /opt/
[root@nfs-server ~]# vi /etc/exports
/opt/test 172.24.3.0/24(rw,no_root_squash,no_all_squash,sync,anonuid=501,anongid=501)
[root@nfs-server ~]# exportfs -r
[root@nfs-server ~]# service rpcbind start
[root@nfs-server ~]# service nfs start
[root@nfs-server ~]# chkconfig rpcbind on
[root@nfs-server ~]# chkconfig nfs on
[root@nfs-server ~]# showmount -e 172.24.3.26
Export list for 172.24.3.26:
