Starting apache fails (could not bind to address 0.0.0.0:80)

Question

Update: Already fixed, it seems that one of VirtualHosts configurations files was wrong in sites-enabled.

I have Ubuntu 11.10

When I run the command to start apache2:

sudo /etc/init.d/apache2 start 

I get the following error message:

Starting web server apache2
apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName (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 Action 'start' failed.

I run this command in order to get the process that is using the port 80:

sudo netstat -ltnp | grep ':80' 

Which returns this output:

tcp6       0      0 :::80                   :::*                    LISTEN      1176/ 

To know which process is I run this command:

ps -wlp1176 

That returns:

F S   UID   PID  PPID  C PRI  NI ADDR SZ WCHAN  TTY          TIME CMD 5 D    33  1176     1  0  80   0 -     0 exit   ?        00:00:00 apache2 

But if I try to kill the process:

sudo kill -9 1176 

It doesn't kill it, if I run again the netstat command still appears listening and apache start fails.

Any suggestions?

Answer 1

Worked for me running this command:

fuser -k -n tcp 80 

Answer 2

It may be skype or nginx using the port 80.

Try shutting down skype, or running: sudo /etc/init.d/nginx stop
