shell腳本檢查網站是否正常

linux系統運維過程中，經常會遇到些問題，有時候問題會比較麻煩，此時shell腳本的優勢就體現出來，下面我來介紹幾種查看網站是否正常的shell腳本

其一

#!/bin/bash
function usage(){
echo $"usage:$0 url"
exit 1
}

function check_url() {

wget --spider -q -o /dev/null --tries=1 -T 5 $1
if [ $? -eq 0 ]
then
echo "$1 is yes."
exit 0
else
echo "$1 is fail."
exit 1
fi
}

其二

#!/bin/bash
. /etc/init.d/functions
num=`curl -I -m 5 -s -w "%{http_code}\n" -o /dev/null 192.168.100.141:8080`
if [ $num -eq 200 ]
then action "ok!" /bin/true
else action "failure" /bin/false
fi

其三

. /etc/init.d/functions
curl -s -o /dev/null 192.168.100.141:8080
if [ $? -eq 0 ]
then action "Web site access is normal" /bin/true
else action "Failure of website access" /bin/false
fi

其四

#!/bin/bash
. /etc/init.d/functions
wget --spider -T 5 -q -t 2 192.168.100.141:8080

if [ $? -eq 0 ]
then action "Web site access is normal" /bin/true
else action "Failure of website access" /bin/false
fi
