线上一个简单检测Ping状态的邮件报警脚本

w5wfwe

Step1.安装sendmail来发邮件
# yum -y install sendmail
# /etc/init.d/sendmail start
# chkconfig sendmail on
Step2.安装邮件客户端
# yum -y install mutt
  2.1添加发件人信息，如下

  # vim /etc/Muttrc
  set charset="utf-8"           #设置发邮件编码

  set envelope_from=yes
  set rfc2047_parameters=yes    #解决附件乱码问题
  set realname="报警"           #发件人别名
  set use_from=yes              #指定是否显示别名
  set from=monitor@test.com     #发送人地址
Step3.Ping主机状态脚本
# vim ping.sh

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

#!/bin/bash # DATE=`date +%F_%H:%M` LOG=/root/ping-monitor/ping.log IP=/root/ping-monitor/ip.txt CLEAN=`cat $LOG | wc -l` for i in $(cat $IP); do         ping -c 2 $i &>/dev/null         if [ $? -eq 0 ];then                 echo "$DATE $i Host ping is success." >> $LOG         else                 echo -e "Date : $DATE\nHost : $i\nProblem : Ping is failed, Please check ! ! !" | mutt -s "Ping" xxx@163.com         fi done #如果日志文件超30条，则清空         if [ $CLEAN -ge 30 ];then                    echo "" > $LOG         fi

Step4.添加任务计划
# crontab -e
*/1 * * * * /bin/bash /root/ping-monitor/ping.sh

对于多个IP，你也可以试试fping命令

[Bash shell] 纯文本查看 复制代码

ping -c 2 $i &>/dev/null
        if [ $? -eq 0 ];then
                echo "$DATE $i Host ping is success." >> $LOG
        else
                echo -e "Date : $DATE\nHost : $i\nProblem : Ping is failed, Please check ! ! !" | 
mutt -s "Ping" [url=mailto:xxx@163.com]xxx@163.com[/url] 
        fi

可以一句搞定：

[Bash shell] 纯文本查看 复制代码

 ping -c 2 $i >/dev/null && echo "$DATE $i Host ping is success." >> $LOG  || echo -e "Date : $DATE\nHost : $i\nProblem : Ping is failed, Please check ! ! !" | mutt -s "Ping" [url=mailto:xxx@163.com]xxx@163.com[/url]
