Suddenly, my server is down without any conf or something

I did not do anything on my server (vps account on linode.com) such as configuration or something. But, suddenly my server is down. When i try to start apache, i saw this error开发者_运维问答 message: ( Starting web server: apache2(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 failed! )

I did try to start apache with some way and i face now "Starting web server: apache2 failed!"

Thanks for your help, Erman

This probably means another server (probably apache itself) is running on same port. If you have shell access to server, try to determine which process is using port 80. (netstat --listen perhaps, do some google) and then kill the process by kill command.

Have you tried linode.com support? This is probably your best bet.

You could also try restarting all of your services (not just Apache, but everything that is available to you to restart).
