1、准备AIX服务器

默认安装完AIX5.3后，先停止nfs和portmap两个进程，然后删掉一些和NFS有关的文件

# stopsrc -g nfs
0513-044 The biod Subsystem was requested to stop.
0513-044 The nfsd Subsystem was requested to stop.
0513-044 The rpc.mountd Subsystem was requested to stop.
0513-044 The rpc.lockd Subsystem was requested to stop.
0513-044 The rpc.statd Subsystem was requested to stop.
#-g表示停止一组nfs相关的进程

# stopsrc -s portmap
0513-044 The portmap Subsystem was requested to stop.
#cd /etc
# rm -rf sm sm.bak state xtab rmtab

2、配置AIX的NFS服务器

可以直接手动配置/etc/exports或使用smit工具配置，因为AIX的NFS和Linux的配置文件内容不同，所以建议使用smit工具来配

这是我通过smit配置好的/etc/exports文件内容：
# cat /etc/exports
/mnt -sec=sys:krb5p:krb5i:krb5:dh:none,rw,root=192.168.3.160,access=192.168.3.161:192.168.3.160#

我将/mnt目录共享出去，设置只允许192.168.3.160可以对共享目录写操作，能够访问的服务器有192.168.3.161和192.168.3.160，sec是数据加密方法。配置完后，使用exportfs命令将/etc/exports的内容更新至/etc/xtab文件中，/etc/xtab文件是NFS读取的内容，所以这步很关键，如果不用这个命令，其它的节点是无法正确挂载NFS共享目录的：

# exportfs -a

这里要注意一下：NFS客户端的IP地址要写到/etc/hosts文中，并要指定机器名，否则是无法挂载AIX上的NFS共享目录

3、启动NFS并测试

# startsrc -s portmap
0513-059 The portmap Subsystem has been started. Subsystem PID is 233644.
# startsrc -g nfs
0513-059 The biod Subsystem has been started. Subsystem PID is 245894.
0513-059 The nfsd Subsystem has been started. Subsystem PID is 213136.
0513-059 The rpc.mountd Subsystem has been started. Subsystem PID is 172270.
0513-059 The nfsrgyd Subsystem has been started. Subsystem PID is 217294.
0513-059 The gssd Subsystem has been started. Subsystem PID is 221400.
0513-059 The rpc.lockd Subsystem has been started. Subsystem PID is 217296.
0513-059 The rpc.statd Subsystem has been started. Subsystem PID is 221402.
#

在AIX上查看NFS的共享目录

# showmount -e localhost
export list for localhost:
/mnt (everyone)
#

在Linux上查看AIX的NFS共享目录：

test01:~ # showmount -e 192.168.3.162
Export list for 192.168.3.162:
/mnt (everyone)
test01:~ #

Linux系统挂载NFS目录

test01:~ # mount 192.168.3.162:/mnt /mnt。
