java - 无法联系本地主机 :8005. 关闭 tomcat 时 Tomcat 可能无法运行错误

Question

您好，我正在尝试关闭和启动 tomcat 服务器。但是我在运行 shutdown.sh 时出现以下错误。请检查以下错误并建议我完成。

错误:

Answer 1

有一些应用程序在端口 8005 上运行，因此 tomcat 无法在该端口上绑定(bind)网络。您的 shutdown.sh 将抛出异常，因为服务器尚未启动(因为启动服务器时出现问题)

• 解决方案 1(推荐):将/opt/tomcat8/conf/server.xml 中的端口从 8005 更改为 8006
• 解决方案 2:请通过 netstat -tulnp | 检查哪个应用程序正在使用 8005 | grep 8005 并将其关闭。
