Linux下關閉tomcat報錯，具體如下：

Using CATALINA_BASE:   /home/alpha/apache-tomcat-7.0.62
Using CATALINA_HOME:   /home/alpha/apache-tomcat-7.0.62
Using CATALINA_TMPDIR: /home/alpha/apache-tomcat-7.0.62/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /home/alpha/apache-tomcat-7.0.62/bin/bootstrap.jar:/home/alpha/apache-tomcat-7.0.62/bin/tomcat-juli.jar

報錯原因：

        tomcat埠被佔用，或者tomcat在沒開啟的時候就關閉，導致報錯；

解決方案：

        1.使用命令：ps aux | grep tomcat      檢視tomcat的所有程序號

        2.使用命令：kill -9 程序號    依次關閉佔用埠的程序，然後重新啟動tomcat

     3.如果第二步不好使，則使用命令：sudo su -        獲取超管許可權，再使用命令：/home/alpha/apache-tomcat-7.0.62/bin/startup.sh  （即你的tomcat的startup.sh檔案的位置），執行即可啟動tomcat成功。
