启动tomcat时报错:Address already in use [linux]

测试服务器 
tomcat启动时,访问test.varkj.com :8080/sms/Auth/main时报错,查看日志
INFO [main] org.apache.catalina.startup.Catalina.start Server startup in 25736 ms
SEVERE [main] org.apache.catalina.core.StandardServer.await StandardServer.await: create[localhost:8005]: java.net.BindException: Address already in use
使用su进入,然后在su的环境下使用 ./shutdown.sh 然后退出su环境
然后使用 sudo ./startup.sh 启动服务
