Linux高阶—shell远程批处理脚本（七）

目录

介绍：简单、实用的批处理脚本

案例一：批量下发远程执行命令

案例二：批量下发文件

expect是处理交互式命令的命令，它可以将类似ssh登录，ftp登录等等需要交互式的场景自动输入登录账号密码， 使其完成自动化运行。

#Remote execution tool
vim remote.sh 

#!/bin/bash
_work_dir=/root/tmp
#Build workdir directory
    if [ ! -d ${_work_dir} ]
    then
        mkdir ${_work_dir}
    fi
_log_dir=/root/tmp/log
#Build log directory
    if [ ! -d ${_log_dir} ]
    then
        mkdir ${_log_dir}
    fi
	
touch ${_log_dir}/check.log 
_check_msg=${_log_dir}/check.log

function info() {
    echo -e "33[32m [INFO] 33[0m$@ "
}
function warn() {
    echo -e "33[31m [WARN] 33[0m$@"
}

      continue
   fi
  done

#remote common_user.exp
vim common_user.exp

#!/usr/bin/expect -f
set timeout 5

set host_name  [lindex $argv 0]
set host_ip    [lindex $argv 1]
set host_un    [lindex $argv 2]
set host_pw    [lindex $argv 3]
set CMD        [lindex $argv 4]

set login_flag 1

spawn ssh ${host_un}@${host_ip}

 expect {
   "yes/no" {send "yesr"; exp_continue}
   "password:" {send "${host_pw}r"}
   "Password:" {send "${host_pw}r"}
 }
 expect {
   "${host_name}" {set login_flag 0 ;send "${CMD}r"}
   expect eof
 }
send "exitr"
expect eof
exit $login_flag


#remote root_user.exp
vim root_user.exp

#!/usr/bin/expect -f
set timeout 5

set host_name  [lindex $argv 0]
set host_ip    [lindex $argv 1]
set host_un    [lindex $argv 2]
set host_pw    [lindex $argv 3]
set root_pw    [lindex $argv 4]
set CMD        [lindex $argv 5]

set login_flag 1

spawn ssh ${host_un}@${host_ip}

 expect {
   "yes/no" {send "yesr"; exp_continue}
   "password:" {send "${host_pw}r"}
   "Password:" {send "${host_pw}r"}
 }
 expect {
   "${host_name}" {set login_flag 0 ;send "su -r"; exp_continue}
   "password:" {send "${root_pw}r"}
   "Password:" {send "${root_pw}r"}
 }
 expect {
   "*${host_name}*#" {set login_flag 0 ;send "${CMD}r"}
   expect eof
 }
send "exitr"
expect eof
exit $login_flag

执行结果如下：
