| 导读 | linux系统运维过程中，经常会遇到些问题，有时候问题会比较麻烦，此时的优势就体现出来，下面我来介绍几种查看网站是否正常的shell |
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
