Question

我在服务器上安装了tomcat7。我们里面有一个应用程序。现在应用程序崩溃了。当我们尝试登录时，没有创建会话。所以我想删除TOMCAT7主文件夹下temp内的文件。

现在我的问题，

删除临时文件夹是否安全？
删除后会有任何问题吗？

这是日志catalina.log

Answer 1

好像另一个应用程序正在使用该端口。如果应用程序已绑定到端口，则另一个应用程序无法使用/绑定到同一端口。检查哪个应用程序绑定到该端口。试试这个：

netstat -ntl | grep :8080

查看已经使用8080的进程。

如果要更改Tomcat的端口，请检查目录 TOMCAT_HOME \ conf 中的文件 server.xml ，如果 8080，将提及端口地址，尝试将其更改为 8081 或其他任何内容并启动服务器并点击localhost：8081进行检查。

在 server.xml 中，代码如下所示：

<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />

此外，如果您想知道哪个进程正在使用该端口，请尝试以下方法：

netstat -aon | findstr 0.0:8080

这将在最后一栏中为您提供进程ID。然后从任务管理器中找到具有该进程ID的进程，您将知道正在使用该端口的进程。
