NFS简介

NFS就是Network File System的缩写，它最大的功能就是可以通过网络，让不同的机器、不同的操作系统可以共享彼此的文件。​NFS服务器可以让PC将网络中的NFS服务器共享的目录挂载到本地端的文件系统中，而在本地端的系统中来看，那个远程主机的目录就好像是自己的一个磁盘分区一样，在使用上相当便利．由於在工作中非常實用,此處將其寫成了兩個腳本,以便於後續使用時候查看.

服务|客户端shell脚本

服務端:

服務端將對應內容寫到/etc/exports中,並重啓nfs-kernel-server即可;

#!/bin/bashusage()
{echo "usage:$0 usable_ip share_pathbash nfs_mount.sh 127.0.0.1 /home/user/dir1"
}main()
{# back up fstabuser=xgBAKCUP=/home/$user/backup/nfsif [ ! -d $BAKCUP ];thensudo mkdir -p $BAKCUPficp /etc/exports ${BAKCUP}/exports.$(date +'%Y%m%d%H%M')# prepare dirif [ ! -d $2 ];thensudo mkdir -p $2fisudo touch  $2/nfs-test.txt# install nfs-commondpkg -l | grep nfsif [ $? -ne 0 ];thenapt-get install -y nfs*if [ $? -ne 0 ];thenecho "install nfs* failed!"exit 1fifidpkg -l | grep rpcbindif [ $? -ne 0 ];thensudo apt-get install -y rpcbindif [ $? -ne 0 ];thenecho "install rpcbind failed!"exit 1fifi#mount_strcat /etc/exports | grep $2if [ $? -ne 0 ];thenmount_str=$2'  '$1'(rw,sync,no_subtree_check)'sudo echo $mount_str >> /etc/exportsfi# check if mount successsudo service nfs-kernel-server restart
}main $1 $2

客戶端:

將相應內容寫到/etc/fstab中,並mount即可;

#!/bin/bash# author: xg
# email : 
# function： nfs客户端挂载

{echo "usage:$0 nfs_server_ip share_path local_pathbash nfs_mount.sh ip /home/user/dir1 /home/user/dir2"
}main()
