nfs:centos 6.6 预装好了

服务端：

[root@203-test shared]# vim /etc/exports
/opt/shared 172.16.1.0/24(rw,sync,no_root_squash)

说明：/opt/shared 为共享的目录位置； *(rw,no_root_squash) *为任意IP都可以访问 rw为可进行读写访问 no_root_squash 为拥有这个目录所有者的权限。

[root@203-test shared]# service nfs restart

客户端：

mount -t nfs -o rw 192.168.109.130:/opt/shared /opt/shared 命令完成挂载(远端/opt/shared 挂载到本地/opt/shared)

要想每次启动机器的时候自动挂载，可使用命令 vi /etc/fstab 编辑，在最后面加上 192.168.109.130:/var/ftp /nfs/ftp nfs defaults 0 0 ，保存退出。这样在每次启动的时候就会自动挂载 192.168.109.130:/var/ftp 这个NFS 共享了。

用 mount 方式挂载 NFS 并不是个很可靠的方式，当遇到断网或挂载时 NFS 服务器重启，都会导致客户端上的 NFS 无法访问的问题。但这也是能解决的，使用 autofs 服务的方式挂载就不会有这个问题了。回头找时间把这个经验也分享出来。

<span style="font-size:10px;">#umount /data1/logs/web1logsumount.nfs: /data1/logs/web1logs: device is busyumount.nfs: /data1/logs/web1logs: device is busy</span>

方法一：
fuser -m -v /data/
          用户进程号权限   命令
/data/:   root 2798    ..c.. bash
          root 2996    ..c.. su
如上所示，有两个进程占用了，将其kill掉，再重新取消挂载。
kill -9 2798 2996
umount /data1/logs/web1logs

方法二：
umount -l /data1/logs/web1logs

方法三：
fuser -km /data1/logs/web1logs
