##定义QQ邮箱的账号和密码，你需要修改成你自己的账号和密码（请不要把真实的用户名和密码放到网上公开，否则你会死的很惨）
    sendqqmail('[email protected]','aaaaaaaaaa','[email protected]',to,subject,content)
if __name__ == "__main__":
    main()
    
    
#####脚本使用说明######
#1. 首先定义好脚本中的邮箱账号和密码
#2. 脚本执行命令为：python mail.py 目标邮箱 "邮件主题" "邮件内容"

vim mail.sh

log=$1
t_s=`date +%s`
#时间戳1
t_s2=`date -d "2 hours ago" +%s`
#时间戳2（两个小时之前的时间）
#定义该时间戳的目的是保证第一次执行该脚本时v大于一小时
#因为只有发生故障的时候才会执行该脚本，所以第一次执行必须要报警
if [ ! -f /tmp/$log ]
then
    echo $t_s2 > /tmp/$log
fi
#创建记录时间戳的日志文件
t_s2=`tail -1 /tmp/$log|awk '{print $1}'`
echo $t_s>>/tmp/$log
v=$[$t_s-$t_s2]
#两个时间戳的间隔时间
echo $v
#计时器：
if [ $v -gt 3600 ]
then
#如果时间间隔大于3600s，则启动报警系统
    ./mail.py  $1  $2  $3
    echo "0" > /tmp/$log.txt
#$log.txt为计数器文件：
else
    if [ ! -f /tmp/$log.txt ]
    then
        echo "0" > /tmp/$log.txt
