Question

I'm doing static code analysis with sonarqube, but installion was failed. when i type on browser

http://localhost:9000/sonar.  

This site can’t be reached

localhost refused to connect. Search Google for localhost 9000 sonar

I install by using this site..

terminal :

   naveen@naveen-Inspiron-3542:~$ telnet localhost 9000

Answer 1

You already have something else on port 9000 that isn't sonar when you telnet in , it will need to be stopped before anything else can bind to that port.

use losf to find out which process it is

lsof -i:9000

for more info on lsof see this, its not installed by default on a lot of distros.

Answer 2

If i was you ,first i will delete every thing and download another version on SQ. Then follow the same set of procedures to host the server. It dont take much time.
