标签：var bubuko 远程脚本 average 监控 host add 功能

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
#!/bin/bash
echo -e "\033[31msystem time: `date "+%Y-%m-%d %H:%M:%S"`\033[0m"
count=`ifconfig |grep Ethernet |grep ‘^e‘ |awk ‘{print $1}‘|wc -l`
for i in `ifconfig |grep Ethernet |grep ‘^e‘ |awk ‘{print $1}‘`
do
if [ $count -gt 1 ];then
em1=$i
em2=$i
else
em1=$i
fi
done
Hostname=`hostname`
em1_ip=`ifconfig $em1 |grep "inet addr" |awk ‘{print $2}‘|awk -F: ‘{print $2}‘`
echo -e "Hostname:"$Hostname "${em1}_IP:" $em1_ip

#system load and process number

total_process=$(ps -ef |wc -l)
echo "load_average: ${load_average}"
echo "running_process: ${running_process}"
echo "total_process: ${total_process}"

Host_running_time=$(uptime |sed ‘s/^.*up//‘ | awk -F "," ‘{print $1,$2}‘)
User_connection_number=$(uptime |cut -d , -f 3)
echo -e "Host_running_time:\t${Host_running_time}\t"
echo -e "User_connection_number:${User_connection_number}"

echo -e "Total_Mem: ${Total_Mem}M\t\t" "Usage_Mem: ${Usage_Mem}M\t"
echo -e "Free_Mem: ${Free_Mem}M\t\t" Mem_Usage_Percent: ${Mem_Usage_Percent}%

echo -e "Swap_Free_Mem: ${Swap_Free_Mem}M\t\t" Swap_Mem_Usage_Percent: ${Swap_Mem_Usage_Percent}%

#Disk monitoring

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
