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="/"; 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;
