NFS服务端：
1：查看NFS进程
# lssrc -g nfs
Subsystem Group PID Status
biod nfs 184502 active
nfsd nfs 120418 active
rpc.mountd nfs 108260 active
rpc.lockd nfs 153268 active
rpc.statd nfs 87628 active
nfsrgyd nfs inoperative
gssd nfs inoperative
注：AIX5.3支持NFS v2，v3，v4三个版本，默认使用NFS v3。nfsrgyd和gssd这两个守护进程是v4新增加的程。
实例：
将134.160.46.138的/usr2/crnop/data/cdl，只读权限，共享134.160.46.162/usr2/crnop/data/cdl138
2：配置共享目录
编辑/etc/exports
#vi /etc/exports
/usr2/crnop/data/cdl -ro,access=XXX(客户端主机名)
注释：
access：只允许134.160.46.162访问/usr2/crnop/data/cdl目录，其他机器不允许访问 ro：/usr2/crnop/data/cdl目录被设置为只读，若无任何参数，则默认为rw
3:使用命令
# exportfs -a
读取/etc/exports文件，才能把内容共享出去，使其他机器的用户可以使用本机的文件。
4：添加hosts文件
#vi /etc/hosts
134.160.46.162 xxx
4:查看NFS服务端是否共享该目录
#showmount -e
export list for HUNCRNOPAPP:
/usr2/crnop/data/cdl vnode1
5：启动NFS
# mknfs -N

二：客户端挂载NFS服务器中的共享目录
1：添加hosts内容
#vi /etc/hosts
134.160.46.138 yyy
2:挂载共享目录
错误挂载格式：
[root@vnode1 ~]# mount -t nfs 134.160.46.138:/usr2/crnop/data/cdl /usr2/crnop/data/cdl138
报错信息：
"mount.nfs: Remote I/O error
解决方法：
aix nfs share to linux
mount报错
解决办法：mount加选项-o nfsvers=3或者-o nfsvers=2
正确挂载：
[root@vnode1 ~]# mount -t nfs -o nfsvers=3 134.160.46.138:/usr2/crnop/data/cdl /usr2/crnop/data/cdl138
3：查看是否挂载：
[root@vnode1 ~]# mount |grep nfs
