現(xiàn)在都流行自動化運維了，可能目前技術(shù)不夠，很多自動化工具還不怎么會用，所以本次只是通過ssh來實現(xiàn)功能。

說明：自己寫的一個簡單腳本，只是實現(xiàn)了基礎(chǔ)功能，還有待優(yōu)化。

一共三臺機(jī)器：

master：192.168.4.91

slave1：192.168.4.45

slave2：192.168.4.96

在slave1上遠(yuǎn)程執(zhí)行master、slave2上的腳本，結(jié)果顯示或者放到本地。當(dāng)然多臺系統(tǒng)也行。

一、腳本功能主要是監(jiān)控系統(tǒng)的一些資源，像cpu，磁盤，網(wǎng)速等等。System_Load.sh

二、拷貝腳本到其他服務(wù)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、用戶和IP對應(yīng)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、遠(yuǎn)程執(zhí)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
