Linux下NFS配置学习(2)

在服务端启动nfs进程(实际上是要启动portmap和nfs进程)

[root@rac1 ~]# /etc/init.d/portmap start

Starting portmap: [ OK ]

[root@rac1 ~]# /etc/init.d/nfs start

Starting NFS services: [ OK ]

Starting NFS quotas: [ OK ]

Starting NFS daemon: [ OK ]

Starting NFS mountd: [ OK ]

Starting RPC idmapd: [ OK ]

再次在客户端连接

[root@rac2 init.d]# mount 192.168.0.5:/disk0 /wyl

mount: 192.168.0.5:/disk0 failed, reason given by server: Permission denied

此报错信息是因为没在server端授权client端来连接,其实道理很简单,必须在服务端来决定哪些IP可以来mount,我的哪个分区可以被mount.

在服务器端编辑/etc/wxports文件

[root@rac1 ~]# vi /etc/exports

/disk0 192.168.0.6(rw)

第一列定义的是服务端哪个分区可以被mount,第二列定义的是哪些客户端IP可以来mount.

注意修改/etc/export后,要重起nfs进程.

vi /etc/exports

/disk0 192.168.0.6(rw)

"/etc/exports" 1L, 24C written

[root@rac1 ~]# more /etc/exports

/disk0 192.168.0.6(rw)

[root@rac1 ~]# /etc/init.d/nfs restart

Shutting down NFS mountd: [ OK ]
