无法在Linux上使用spring boot启动tomcat

问题描述：

突然间我无法启动我的嵌入式tomcat。

Suddenly I cant start my embedded tomcat.

我得到：

[main] ERROR o.a.coyote.http11.Http11NioProtocol - Failed to start end point associated with ProtocolHandler ["http-nio-86"]
java.net.SocketException: Permission denied

我尝试更改tomcat端口，
我尝试设置权限：chmod 777 src / -R

I tried changing tomcat port, I tried setting permissions: chmod 777 src/ -R

我使用linux Mint 17

I use linux Mint 17

我不知道该怎么办...

I have no idea what to do...

这是堆栈跟踪：

Linux不允许普通用户绑定到< = 1024的TCP端口。讨论了here 。你试图绑定到86，因此它失败了权限被拒绝。最快和最安全的解决方案是使用大于1024的值配置端口。

Linux doesn't allow a normal user to bind to a TCP port that's <= 1024. There's a discussion of the reasons for that here. You're attempting to bind to 86 and, therefore, it's failing with "Permission denied". The quickest and safest solution is to configure the port with a value that's > 1024.

当您使用Boot的嵌入式Tomcat实例时，端口配置为 application.properties 使用 server.port 属性。

As you're using Boot's embedded Tomcat instance, the port's configured in application.properties using the server.port property.
