Go Revel框架端口9000已在使用中

Question

I'm following along with the Go Revel framework nicely until I go to run the test app:

$ revel run myapp

which gives me the all the correct output but also gives the following error:

ERROR 2013/09/30 19:51:41 harness.go:167: Failed to start reverse proxy: listen tcp 
<nil>:9000: address already in use

When I run this:

$ sudo lsof -n -i4TCP:9000 | grep LISTEN

I get this:

COMMAND   PID USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
php-fpm 11007 root   11u  IPv4 0xffffff801441dde0      0t0  TCP localhost:cslistener (LISTEN)
php-fpm 11008 _www    0u  IPv4 0xffffff801441dde0      0t0  TCP localhost:cslistener (LISTEN)
php-fpm 11009 _www    0u  IPv4 0xffffff801441dde0      0t0  TCP localhost:cslistener (LISTEN)
php-fpm 11010 _www    0u  IPv4 0xffffff801441dde0      0t0  TCP localhost:cslistener (LISTEN)

I have a PHP-NGINX app running on port 80 and don't want to lose that but have no idea whether this means this PHP app is blocking my Go app from running.

Can anyone chime in?

I'm running on MacOS X 10.7.5.

You can change the port of a revel application with either:

1. Editing the config/app.conf file and setting

   http.port = 8888
   

2. Running your revel application with a parameter specifying the port. You'll also need to specify either dev or prod to state your environment:

   revel run myapp dev 8888
