本文介绍了一款用于自动监控Apache服务器状态并实现自动重启的Shell脚本。该脚本适用于root用户，能够实时监测Apache服务运行情况，一旦发现服务异常，立即尝试重启。若重启失败，则会终止进程再次启动，确保服务的高可用性。

在这里插入图片描述

自动监控apache服务状态并重启的shell脚本

if [ ${num} -lt 1 ] ;then

  echo $curdate" this timestamp is for the forum's conection full" >> /home/opp/mon.log 2>&1 &
  killall -9 /opt/lampp/bin/httpd
  sleep 3
  /opt/lampp/lampp start >> /home/opp/mon.log 2 >&1 &

目的：
1.监控apache服务器的状态
2.当发现apache down机就自动重启apache服务
3.重启apache不成功，杀死该进程。并重新启动
4.记录日志
