Cant start tomcat with spring boot on linux

Question

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"]

Answer 1

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.
