Linux NFS 服务部署

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

二、客户端配置

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.
