Setting up Linode (Ubuntu 10.04 32bit) nginx not starting. 98: address already in use

Question

Hello having a little issue with setting up linode via Railscast instructions of Ep. #335

My Configuration for this server is: Ubuntu 10.04 LTS Disk Image 32bit

I can get this far:

Running both of these work as expected.

apt-get -y update

apt-get -y install curl git-core python-software-properties

When I get to the nginx steps:

add-apt-repository ppa:nginx/stable

apt-get -y update

apt-get -y install nginx

Up to this point all seems to be working properly.

It is here:service nginx start

that I get the following in response:

 * Starting nginx nginx
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()

I have tried stopping, restarting and reloading nginx but I cannot get anything to change. Any suggestions would be greatly appreciated. Thanks in advance.

It seems like you have something else running or blocking that port. try running: sudo netstat -pan | grep ":80"

which should give you a hint on what is running on there. Maybe its a uwsgi/apache2/tomcat etc. Could be a lot running there.

EDIT:

i now know whats the problem as i had it myself now on a debian server.

listen   80; ## listen for ipv4
listen   [::]:80 default ipv6only=on; ## listen for ipv6

You should comment the first or the second line (depends on if you want to listen of ipv6 or ipv4. That was the problem i had.

Things i'd try: 1. sudo service nginx restart 2. Then try to reconfigure the nginx to use some other port if that works perfectly you should digg more into it. 3. post output of sudo netstat -tulpean – Julian Hille Feb 19 '13 at 23:06
sorry Stack Over Flow cut me off. It returned: `udp 0 0 66.xxx.xxx.xxx:xxxxx 80.xxx.xxx.xx:xxx ESTABLISHED xxxx/ntpd` – samuelkobe Feb 19 '13 at 23:09
did you really used: ":80" ?? ```sudo netstat -pan | grep ":80"``` use everything in between the ``` – Julian Hille Feb 19 '13 at 23:11

I changed the port to 81 to test and it still says the address is already in use – samuelkobe Feb 19 '13 at 23:58
That was it. Much appreciated. I know this TY is long over due. – samuelkobe May 02 '13 at 22:48

I don't know if this is the proper solution, but it worked for me after I commented the line:

listen 80;

in /etc/nginx/sites-enabled/default
