批量检查多个网站地址是否正常
要求:shell数组方法实现,检测策略尽量模拟用户访问思路
http://www.etiantian.org
http://www.taobao.com
http://oldboy.blog.51cto.com
http://10.0.0.7
思路:
1.url列表作为数组
2.check_url
3.判断输出。
解答:
脚本如下:
[root@db02 oldboy26]# cat ms6.sh #!/bin/bash [ -f /etc/init.d/functions ] && source /etc/init.d/functions #define array url list array=( http://www.etiantian.org http://www.taobao.com http://oldboy.blog.51cto.com http://10.0.0.7 ) #check_url wait(){ echo -n "wait 3s" for((i=0;i<3;i++)) do echo -n "." sleep 1 done echo } check_url(){ wget -T 5 -t 2 --spider $1 &>/dev/null RETVAL=$? if [ $RETVAL -eq 0 ];then action "check $1" /bin/true else action "check $1" /bin/false fi return $RETVAL } main(){ wait for((i=0;i<${#array[@]};i++)) do check_url ${array[i]} done } main 验证: [root@db02 oldboy26]# sh ms6.sh wait 3s... check http://www.etiantian.org [ OK ] check http://www.taobao.com [ OK ] check http://oldboy.blog.51cto.com [ OK ] check http://10.0.0.7 [FAILED] [root@db02 oldboy26]#
如何实现只检测一个url
[root@db02 oldboy26]# cat ms6-01.sh #!/bin/bash [ -f /etc/init.d/functions ] && source /etc/init.d/functions #check_url wait(){ echo -n "wait 3s" for((i=0;i<3;i++)) do echo -n "." sleep 1 done echo } check_url(){ wget -T 5 -t 2 --spider $1 &>/dev/null RETVAL=$? if [ $RETVAL -eq 0 ];then action "check $1" /bin/true else action "check $1" /bin/false fi return $RETVAL } main(){ wait check_url $1 } main $* 验证: [root@db02 oldboy26]# sh ms6-01.sh http://oldboy.blog.51cto.com wait 3s... check http://oldboy.blog.51cto.com [ OK ] [root@db02 oldboy26]# sh ms6-01.sh http://abc.134.com wait 3s... check http://abc.134.com [FAILED] [root@db02 oldboy26]#
