Linux 如何通过某一台服务器调用执行多台远程服务器上的脚本，结果显示在本地？

Posted 2021-01-02 北漂-boy

现在都流行自动化运维了，可能目前技术不够，很多自动化工具还不怎么会用，所以本次只是通过ssh来实现功能。

说明：自己写的一个简单脚本，只是实现了基础功能，还有待优化。

一共三台机器：

master：192.168.4.91

slave1：192.168.4.45

slave2：192.168.4.96

在slave1上远程执行master、slave2上的脚本，结果显示或者放到本地。当然多台系统也行。

一、脚本功能主要是监控系统的一些资源，像cpu，磁盘，网速等等。System_Load.sh

[root@master ~]# cat System_Load.sh

while read line
do
em[$i]=$line
i=`expr $i + 1`
done < /tmp/.value
#echo $i
#i=1
for i in `seq $count`
do
echo "${em[$i]}" > /dev/null
done

if [ $count = 0 ];then

二、拷贝脚本到其他服务器

[root@slave1 monitor]# cat remote_scp.sh
#!/bin/sh
while read user ip
do
user=$user
ip=$ip
remote_cmd=/root/System_Load.sh
scp $remote_cmd $user@$ip:/home/hadoop
done < user_ip.txt

三、用户和IP对应列表

[root@slave1 monitor]# cat user_ip.txt
root 192.168.4.91
root 192.168.4.96
root 192.168.4.45

四、远程执行

[root@slave1 monitor]# cat remote_ssh.sh
#!/bin/sh
while read user ip
do
user=$user
ip=$ip
remote_cmd=/root/System_Load.sh
ssh -n $user@$ip $remote_cmd
done < user_ip.txt

五、结果
