Linux Shell脚本实现检测tomcat

Linux Shell脚本检测tomcat并自动重启

后台运行命令 sh xxx.sh &

查看后台任务:jobs

召唤到前台:fg jobs编号

可以删掉while循环的代码放到crontab里面定时执行，可以将脚本直接后台运行，

#!/bin/bash while [ true ] do url=”https://www.jb51.net/”; httpOK=`curl –connect-timeout 10 -m 60 –head –silent $url | awk NR==1{print $2}`; if [ $httpOK == “200” ];then tomcat6=`ps -ef | grep tomcat | awk NR==1{print $1″ “$2;}`; user=`echo $tomcat6 | awk NR==1{print $1}`; pid=`echo $tomcat6 | awk NR==1{print $2}`; if [ $user != “tomcat” ]; then service tomcat6 start; else kill -9 $pid;sleep 5s;service tomcat6 start;service tomcat6 start;service tomcat6 status; fi; fi; sleep 5m; done;
