FreeBSD配置简单计划任务监控网站

配置每天8点到21点（需要24小时待命的无视这个）每隔5分钟执行一次检测

/etc/crontab新增一条：

*/5 8-21 * * * root /usr/jobdir/job.sh

这里我使用了curl，也可以使用ping，curl需要到/usr/ports/ftp/curl下进行make安装

crontab中要注意path变量（系统能否找到curl? curl路径  /usr/local/bin ），用户权限等问题

[personball@freebsd ~]$ cd /usr/jobdir/
[personball@freebsd /usr/jobdir]$ ls
URL.list	alive.sh	job.sh
[personball@freebsd /usr/jobdir]$

job.sh

#!/bin/bash
#FileName: job.sh
#Author: personball
#Date: 2012-8-13

while read url
do
./alive.sh $url &
done
exit 0

alive.sh

#!/bin/bash
#FileName:alive.sh
#Author:personball
#Date:2012-8-13

if [ $# -ne 1 ]
then
echo "Usage:$0 URL"
exit 1
fi

url=$1
curl -I --connect-timeout 60 -m 60 $url >/tmp/alive.$$ 2>/dev/null  #检测目标
if grep 'HTTP/1.1 200 OK' /tmp/alive.$$ &>/dev/null
then
echo $1" OK!" >>/var/log/alive.log
else
echo $1" Sick!">>/var/log/alive.log
#curl -I ''$1"_is_sick" &>/dev/null  #短信报警
fi
exit 0
