Linux系统下启动Tomcat有时报Address already in use<null...的问题

Linux系统下启动Tomcat有时报Address already in use<null...的问题

 

我知道是端口被占用，可是第壹次启动就是成功的，再关闭后，重启就报错，具体错误码信息如下：

那是因为你的tomcat已经启动了tomcat自带的关闭脚本，有时候关闭看上去成功了，其实并没有关闭。可以使用如下命令查看进程列表：

1

ps -ef | grep java

如果java进程还在，就用如下命令把它们全部手动关闭掉，再启动tomcat就可以解决了。

1

kill -9 pid

其中PID要替换成进程号才行，另外，使用命令ps -ef|grep java可以同时看到五六个进程，需要逐个把它们关闭，然后再重新启动tomcat就不会报上面那个错误了。
