Linux下檢測Apache運行狀態的腳本

定時檢測apache是否啟動，如果沒啟動，自動啟動該服務
#!/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

此腳本加入到計劃任務中，實現定時檢測服務的運行狀況。

在/etc/crontab中加入以上代碼，重啟crond服務以後，即可實現每分鐘檢測一下服務的運行狀況。
