Linux挂载

设备：两台centos6OS安装的时候选择的是"BasicServer"软件配置包。

首先，让两台机器都安装NFS的软件包，如下显示的是服务器端：

[root@roothomes/home]$yum-yinstallnfs-utilsrpcbind

###(建立挂载的目录，并且挂载目录。)

[root@roothomes/etc]$mkdir/opt/centos6

[root@roothomes/etc]$cd/opt/centos6/

[root@roothomes/opt/centos6]$mkdirthisISnfsFile

[root@roothomes/opt/centos6]$ls

###备注:/opt/centos6表示nfs共享的目录192.168.1.0-192.168.1.254区间的IP可以访问，访问权限是自读，root用户

###(启动对应的服务)

[root@roothomes/opt/centos6]$chkconfignfson

安装完毕！

[root@vmBS00~]#serviceiptablesstop

###查看是否能访问nfs服务

[root@vmBS00~]#showmount-e192.168.1.75

Exportlistfor192.168.1.75:

/opt/centos6192.168.1.0/24

[root@vmBS00~]#mount-tnfs192.168.1.75:/opt/centos6//opt/centos6/

[root@vmBS00~]#ls/opt/centos6/

thisISnfsFile

###配置开机自动挂载

[root@vmBS00~]#vi/etc/fstab

###添加#192.168.1.75:/opt/centos6//opt/centos6/nfsnodev,ro,rsize=32768,wsize=3276800
