系统环境：Oracle Linux 5.7
服务端：192.168.1.111
客户端：192.168.1.171
一、服务端配置
1.依次启动portmap和nfs服务
service portmap start
service nfs start
[root@OEL-ASM ~]# service portmap status
portmap (pid ) is running...
[root@OEL-ASM ~]# service nfs status
rpc.mountd is stopped
nfsd is stopped
rpc.rquotad is stopped
[root@OEL-ASM ~]# service nfs start
Starting NFS services: [ OK ]
Starting NFS quotas: [ OK ]
Starting NFS daemon: [ OK ]
Starting NFS mountd: [ OK ]
[root@OEL-ASM ~]# service nfs status
rpc.mountd (pid ) is running...
nfsd (pid ) is running...
rpc.rquotad (pid ) is running...
2.将服务端需要共享的目录配置到/etc/exports文件中
例如在/etc/exports配置文件中添加一行：
/usr2/nfs *(rw)
配置/etc/exports文件后重启nfs服务
[root@OEL-ASM /]# mkdir -p /usr2/nfs
[root@OEL-ASM /]# cd /usr2/nfs
[root@OEL-ASM nfs]# ls
[root@OEL-ASM nfs]# pwd
/usr2/nfs
[root@OEL-ASM nfs]# touch
[root@OEL-ASM nfs]# vi
[root@OEL-ASM nfs]# vi
[root@OEL-ASM nfs]# more
Hello, World! one~
[root@OEL-ASM nfs]# more
Hello, World! two.
[root@OEL-ASM nfs]# pwd
/usr2/nfs
[root@OEL-ASM nfs]# ls -lh
total .0K
-rw-r--r-- root root - :
-rw-r--r-- root root - :
[root@OEL-ASM nfs]# vi /etc/exports
[root@OEL-ASM nfs]# more /etc/exports
/usr2/nfs *(rw)
[root@OEL-ASM nfs]# service nfs restart
Shutting down NFS mountd: [ OK ]
Shutting down NFS daemon: [ OK ]
Shutting down NFS quotas: [ OK ]
Starting NFS services: [ OK ]
Starting NFS quotas: [ OK ]
Starting NFS daemon: [ OK ]
Starting NFS mountd: [ OK ]
[root@OEL-ASM nfs]# showmount -e
Export list for OEL-ASM:
/usr2/nfs *
[root@OEL-ASM nfs]# exportfs
/usr2/nfs <world>
二、客户端配置
1.同样启动服务
service portmap start
service nfs start
2.创建挂载目录挂载服务端映射出来的目录
mkdir -p /usr2/nfs_map mount -t nfs 192.168.1.111:/usr2/nfs /usr2/nfs_map
此时就可以在客户端/usr2/nfs_map目录下看到服务端/usr2/nfs目录下的文件了，如下：
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
55G 11G 41G % /
/dev/sda1 99M 23M 71M % /boot
tmpfs 749M 749M % /dev/shm
192.168.1.111:/usr2/nfs
55G 11G 41G % /usr2/nfs_map
# ls -lh
total .0K
-rw-r--r-- root root - :
-rw-r--r-- root root - : # more
Hello, World! one~
# more
Hello, World! two.
