NFS服务器搭建

创建NFS共享目录，

服务端ip：192.168.1.11 主机名：hate

客户端ip：192.168.1.10 主机名：love

[root@hate ~]# mkdir -p /nfs/backup

[root@hate ~]# chmod -R 777 /nfs

修改/etc/exports

/nfs/backup love(rw,async,nohide,no_subtree_check)

注意：这里的解析名一定要用hostname，否则会出现权限的问题

[root@hate ~]# showmount -e

mount clntudp_create: RPC: Program not registered

遇到这个问题时解决办法

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

[root@hate ~]# showmount -e

Export list for hate:

/nfs/backup love
[root@hate ~]# service nfs restart

[root@hate ~]# chkconfig nfs on

客户端192.168.1.10挂载NFS文件系统

[root@love ~]# mkdir /mynfs

手动挂载

[root@love ~]# mount -o rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,actimeo=0,vers=3,timeo=600 hate:/nfs/backup /mynfs

[root@love ~]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/mapper/VolGroup00-LogVol00

45G 9.3G 33G 23% /

/dev/sda1 99M 12M 82M 13% /boot

tmpfs 1014M 0 1014M 0% /dev/shm

hate:/nfs/backup 45G 6.5G 36G 16% /mynfs

实现开机自动挂载

[root@love ~]# vi /etc/rc.local

#!/bin/sh

#

# This script will be executed *after* all the other init scripts.

# You can put your own initialization stuff in here if you don't

# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local

添加如下配置：这样还可以支持RMAN备份。

modprobe hangcheck-timer hangcheck_tick=30 hangcheck_margin=180

/bin/mount -o rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,actimeo=0,vers=3,timeo=600 hate:/nfs/backup /mynfs

重启系统

[root@love ~]# reboot

[root@love ~]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/mapper/VolGroup00-LogVol00

45G 9.3G 33G 23% /
