批量远程执行命令

在一台机器上远程到多台机器上执行多条命令，怎么实现呢？

写一个登录到多台机器并执行命令的脚本文件remote-exec-command.sh

vim /usr/local/sbin/expect/remote-exec-command.sh#!/usr/bin/expectset host [lindex $argv 0]set command [lindex $argv 1]set user "root"set passwd "root"spawn ssh $user@$hostexpect {"yes/no" {send "yes\r";exp_continue}"password:" {send "$passwd\r"}}expect "]*"send "$command\r"expect "]*"expect eof

写一个远程机器的ip列表集合文件

vim /tmp/desip.txt192.168.221.20192.168.221.30

写一个调用remote-exec-command.sh这个脚本的文件exec.sh

vim /usr/local/sbin/expect/exec.sh#!/bin/bashfor ip in `cat /tmp/desip.txt`; do        ./remote-exec-command.sh $ip "who;ifconfig"done

执行exec.sh

[root@localhost expect]# bash exec.sh spawn ssh root@192.168.221.20root@192.168.221.20's password: Last login: Sun Mar 18 16:47:04 2018 from 192.168.221.10[root@apenglinux-002 ~]# who;ifconfigroot     tty1         2018-03-03 10:46root     pts/0        2018-03-18 13:29 (192.168.221.10)root     pts/1        2018-03-18 10:01 (192.168.221.1)root     pts/2        2018-03-18 16:59 (192.168.221.10)ens33: flags=4163
