服务器多了，一直苦于apache经常的死掉，虽说WHM中有监控apache的进程，但反应时间超慢，通常要在死掉10分钟以上才会重启apache，而10分钟可要损失N多刀刀哈，昨天终于从google中找到了个好的解决方案，证明确实有效，有需要的朋友可以拿去用哈！

用ssh登入到Server，

cd /home

vi restart.sh

复制上面的代码到restart.sh文件中

chmod 777 restart.sh

改变文件权限为可执行

进入计划任务，定时运行监控脚本

cd /etc/cron.d

vi sa-update

copy下面的代码到计划任务中

* * * * * root /home/restart.sh >/dev/null 2>&1

如果想看到运行效果，你可以将/dev/null 2>&1 改为/home/restart.txt

保存文件

一分钟后你应该可以在/home文件中看到restart.txt文件了

现在你可以不再为httpd经常死掉而烦恼了。
