java - Cant start tomcat with spring boot on linux

in Technique[技术] by (71.8m points)

Suddenly I cant start my embedded tomcat.

I get:

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

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

I use linux Mint 17

I have no idea what to do...

This is the stacktrace:

    [main] ERROR o.a.coyote.http11.Http11NioProtocol - Failed to start end point associated with ProtocolHandler ["http-nio-86"]

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.

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