shell编程笔记2–ns挂载

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/bash

usage()

  echo "usage:
  $0


main()

  # back up fstab
  user=xg
  BAKCUP=/home/$user/backup/nfs
  if [ ! -d $BAKCUP ];then
    sudo mkdir -p $BAKCUP
  fi
  cp /etc/exports $BAKCUP/exports.$(date +%Y%m%d%H%M)

  # prepare dir
  if [ ! -d $2 ];then
    sudo mkdir -p $2
  fi
  sudo touch  $2/nfs-test.txt
  
  # install nfs-common
  dpkg -l | grep nfs
  if [ $? -ne 0 ];then
    apt-get install -y nfs*
    if [ $? -ne 0 ];then
      echo "install nfs* failed!"
      exit 1
    fi
  fi
  dpkg -l | grep rpcbind
  if [ $? -ne 0 ];then
    sudo apt-get install -y rpcbind
    if [ $? -ne 0 ];then
      echo "install rpcbind failed!"
      exit 1
    fi
  fi

  #mount_str
  cat /etc/exports | grep $2
  if [ $? -ne 0 ];then
    mount_str=$2  $1(rw,sync,no_subtree_check)
    sudo echo $mount_str >> /etc/exports
  fi
  
  # check if mount success
  sudo 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
# date: 2019-09-29 18:30

usage()

  echo "usage:
  $0


main()

  # back up fstab
  user=xg
  BAKCUP=/home/$user/backup/nfs
  if [ ! -d $BAKCUP ];then
    sudo mkdir -p $BAKCUP
  fi
  cp /etc/fstab $BAKCUP/fstab.$(date +%Y%m%d%H%M)

  # install nfs-common
  dpkg -l | grep nfs-common
  if [ $? -ne 0 ];then
    sudo apt-get install -y nfs-common
    if [ $? -ne 0 ];then
      echo "install nfs-common failed!"
      exit 1
    fi
  fi

  # append to /etc/fstab
  cat /etc/fstab |grep $1
  if [ $? -ne 0 ];then
    mount_str=$1:$2    $3    nfs    rw,async,vers=3,rsize=524288,wsize=524288,acdirmin=5,acdirmax=8,hard,proto=tcp        0       0
    sudo /bin/bash -c "/bin/echo $mount_str  
  fi

  # mkidr $3
  if [ ! -d $3 ];then
    sudo mkdir $3
  fi

  # mount -a
  sudo mount -a
  if [ $? -ne 0 ];then
    echo "mount -a error!"
    exit 1
  fi

  # check if mount success
  df -h $2
  if [ $? -ne 0 ];then
    echo "df -h failed!"
    exit 1
  fi  


main $1 $2 $3
