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;
