Linux脚本实战之SSH执行远端脚本

• 一、系统环境
• 二、脚本要求
• 三、脚本内容
• • 四、执行脚本
  • 1.在本机执行效果
  • 2.远程主机上执行脚本效果

一、系统环境

[root@tianyi ~]# cat /etc/redhat-release 
CentOS Linux release 8.0.1905 (Core) 
[root@tianyi ~]# 

二、脚本要求

1.编写脚本名为ssh_connect.sh脚本
2.通过该脚本连接主机，在本端执行远程主机下的脚本

三、脚本内容

#!/bin/bash
##########################################################
#File Name:ssh_connect.sh
#Version:V1.0
#Created Time:2021-09-22 11:02:17
#Description:
##########################################################

ip_list=("192.168.200.135" "192.168.3.111")
user="root"
remote_commod="/root/ssh_connect.sh"
for ip in ${ip_list[*]}
do
  if [ $ip = "192.168.200.135" ];then
        echo "ssh connetc successful"
   else
       echo "failed!"
fi
  ssh $user@$ip "/root/scripts/ipcheck.sh"
done

四、执行脚本

1.在本机执行效果

[root@control scripts]# ./ssh_connect.sh 
ssh connetc successful
192.168.200.130 is Error!
192.168.200.131 is Error!
192.168.200.132 is Error!
192.168.200.133 is Error!
192.168.200.134 is Error!
192.168.200.135 is OK!
192.168.200.136 is Error!
192.168.200.137 is Error!
192.168.200.138 is Error!
192.168.200.139 is Error!
192.168.200.140 is Error!
failed!
ssh: connect to host 192.168.3.111 port 22: Connection refused
[root@control scripts]# 

2.远程主机上执行脚本效果

[root@node1 scripts]# ./ipcheck.sh 
192.168.200.130 is Error!
192.168.200.131 is Error!
192.168.200.132 is Error!
192.168.200.133 is Error!
192.168.200.134 is Error!
192.168.200.135 is OK!
192.168.200.136 is Error!
192.168.200.137 is Error!
192.168.200.138 is Error!
192.168.200.139 is Error!
192.168.200.140 is Error!
