Amazon EC2 - httpd error on start port 80 - (98)Address already in use: make_sock

Question

I'm unable to get httpd running on my AWS linux instance.

I keep getting the following error whenever I try to start the service.

$ service httpd start

Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

I tried everything I can think of.

-checked port 80, but don't show any running processes

$ netstat -tulpn | grep :80

(No info could be read for "-p": geteuid()=222 but you should be root.)

-checked to see if I had any other entries listening for port 80

$ grep -r Listen /etc/httpd
/etc/httpd/conf/httpd.conf:# Listen: Allows you to ...
/etc/httpd/conf/httpd.conf:# Change this to Listen ...
/etc/httpd/conf/httpd.conf:#Listen 12.34.56.78:80
/etc/httpd/conf/httpd.conf:Listen 80

-tried uninstalling , re-installing with yum installer

I'm fairly new to Linux and setting up servers so I apologize if I'm missing something simple. Any ideas?

Edit: Yikes, I was running ssh on port 80. Thanks you all

Solution

Your netstat -tulpn | grep :80 command clearly shows that you have a service already listening on port 80 :

tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      -
tcp        0      0 :::80                       :::*                        LISTEN      -

Identify this service by running :

sudo netstat -anp | grep :80

Then, Kill/Stop that service and restart httpd.

You have a running process on port 80. Please run and provide result for netstat -anp | grep :80

netstat does show a process running on port 80. Run with sudo to see which process.

Ok, I didn't know I had to run sudo to see the processes. Thanks for that.

[Justin Maat]

Thank you both. I didn't realize I had a process running on the port.
