Linux下检测Apache运行状态的脚本

定时检测apache是否启动，如果没启动，自动启动该服务

#!/bin/sh
check_services()
{
echo "Check services..."
services=""
if [ -z "`ps -A|grep httpd`" ]
then
services="$services httpd"
fi
}

start_services()
{
echo "Start services..."
for start_services in `echo $services`
do
/etc/init.d/$start_services start
done
echo
}

check_services
echo
echo "Check services succeed!"
echo
start_services
echo
echo "Start services succeed!"
echo

此脚本加入到计划任务中，实现定时检测服务的运行状况。

*/1 * * * * root /user/bin/httpcheck.sh

在/etc/crontab中加入以上代码，重启crond服务以后，即可实现每分钟检测一下服务的运行状况。
