监测的应用接口： 新闻接口、天气接口
处理方法：应用接口不可用时自动重启tomcat，并发送告警邮件给相关人员
#!/bin/bash #--------------------------------------------------------- # 功能说明： # 监控指定http服务是否可用，如果不可用立即重启tomcat # # 使用说明： # 1. 将此脚本放置在/home/opentsp/crontab/目录下。 # 2. 修改脚本执行权下为可执行权限。 # 3. 添加到定时任务中，定时执行时间（建议为20分钟） # 4. 修改邮件发送人员信息列表（当服务重启时发邮件给相关人员） # - 周凌飞(2014-08-13) #--------------------------------------------------------- export lc_all=zh_cn.utf-8 #网站地址、参数 server_name="趣驾云接口服务" url_2="http://127.0.0.1/get_rss_news?p=%7b%27chid%27:%27tiyu%27%7d" keyworld_2='' url_3="http://127.0.0.1/get_json_weather?p=%7blon:116.407617,lat:39.993956,date:1%7d" keyworld_3='temperature' #邮件发送列表 mail_ary=( xxxxxxxxx@navinfo.com xxxxxxxxx@navinfo.com xxxxxxxxx@navinfo.com ) #接口调用失败的处理方法 function dofail(){ local ipinfo=$(ifconfig |sed -n '2p'|awk '{print substr($2,6)}'); # 发送邮件 for _v in ${mail_ary[*]} ; do echo "[$server_name 异常] - [$(date -d "0 min" +"%y-%m-%d %h:%m:%s")] - [请求地址: $1] - [请求返回码: $2]" | mail -s ${ipinfo}服务异常 ${_v} done # 写入日志 echo "[error] - [$(date -d "0 min" +"%y-%m-%d %h:%m:%s")] - 返回码[$2] - 重启tomcat服务" >> detect-http.log # 关闭tomcat sh /home/opentsp/crontab/ibr-shutdown.sh exit; } #请求超时时间设置 time_out=40 function docheck(){ local url_x=$1; local keyworld_x=$2; http_status_code=`curl -m $time_out -o /dev/null -s -w "%{http_code}" "${url_x}"` if [ $http_status_code != 200 ];then #请求失败 echo "-> fail - 返回码${http_status_code}"; dofail ${url_x} ${http_status_code}; else #服务器正常响应，检查返回内容 if curl -m ${time_out} -s ${url_x} | grep -q ${keyworld_x};then echo "-> success"; else echo "->> fail"; # 返回内容错误处理 dofail ${url_x} ${http_status_code}; fi fi } # #检查 - 新闻 docheck ${url_2} ${keyworld_2} #检查 - 天气 docheck ${url_3} ${keyworld_3}</pre> <p>将以上代码放入到linux的定时任务中即可，定时任务时间建议为20分钟一次。</p> <p>The above is the detailed content of How to use Crontab to regularly monitor and maintain Tomcat applications in Linux.
