I'm trying to setup nginx on Ubuntu 11.04. I have followed the roughly the directions found here: http://library.linode.com/frameworks/sinatra/debian-6-squeeze . I know it is for Debian, but I basically took those steps and then googled "How to do x in ubuntu 11.04" Although, I did pull the init scripts from their library.
Starting nginx: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()
The command: 'sudo lsof -i:80' returns nothing running on port 80.
How do I troubleshoot this or any ideas on what maybe going wrong?
I saw Nginx + uWSGI on a fresh Ubuntu install - bind error port 80 and tried restarting the computer and running it once and I get the same error. After running it once, I then ran the lsof command.
UPDATE
