【问题描述】：

Tomcat 不工作，但 apache 工作。在 CentOs 6.x 上

我通过Can't access tomcat server on centOS VPS安装了jdk、tomcat和几个步骤。
我可以访问 Apache 页面，但 tomcat 不能。

Apache :http://182.162.94.35/（可以看到示例页面）

Tomcat：http://182.162.94.35:8080（错误）

我不知道是什么问题...人们说通常我需要将tomcat的端口8080更改为另一个，所以我尝试了但还是一样。

这里是 catalina.log...

我也看到了这些错误...

有谁可以解决这个问题...？谢谢。

【问题讨论】：

可能有另一个 tomcat 实例正在运行。尝试将其关闭或将连接器端口 =”8080” 更改为 server.xml 中的其他端口。
@singhr 嗨...我试过了，但遇到了同样的问题。
我明白了。您是否重新启动了tomcat和apache？需要在apache之前启动tomcat。

【解决方案1】：

很明显，您的日志显示问题是由于端口繁忙造成的。因此，正如您自己所说，您应该更改端口。我确定您没有更改端口是正确的。

请查看以下链接：“http://www.mkyong.com/tomcat/how-to-change-tomcat-default-port/”并确保应用您的更改。您可以通过查看日志文件来验证这一点。
