apache服务监控脚本-自动重启apache
日期：2014-05-16 浏览次数：21209 次
[root@localhost shell]# vi apache_monitor.sh
#!/bin/bash
while [ 1 ]
do
wget http://127.0.0.1/a.html > /dev/null 2>&1
if [ $? -ne 0 ]
then
service apache restart >/dev/null 2>&1
else
wt=`cat a.html`
if [ $wt != 'OK' ]
then
service apache restart > /dev/null 2>&1
fi
fi
sleep 2
done
[root@localhost shell]# cat /www/a.html
OK
[root@localhost ~]# lsof -i:80
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
httpd 32105 root 3u IPv4 409340 TCP *:http (LISTEN)
httpd 32109 daemon 3u IPv4 409340 TCP *:http (LISTEN)
httpd 32111 daemon 3u IPv4 409340 TCP *:http (LISTEN)
httpd 32113 daemon 3u IPv4 409340 TCP *:http (LISTEN)
[root@localhost ~]# killall httpd
[root@localhost ~]# lsof -i:80
[root@localhost ~]# lsof -i:80 在我杀死httpd进程的大概一两秒时间内，apache服务没有起来，但是很快就可以了，
如果是在实际生产中，可以把脚本中的sleep时间改成1.

我擦，发现爆表了，忘记了，脚本还没有完善，需要把这东西全干掉
而且我还想要记录apache的重启时间和次数，所以还需要更改脚本
#!/bin/bash
while [ 1 ]
do
wget http://
