Linux系统挂载AIX NFS服务器的配置

  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
