Question

Why is apache pointing to other IP address?

Hy, my apache2 server is not responding. When I access my server, it gives me an error, and when I try to start the server via ssh it also gives an error too.

service apache2 start
[....] Starting web server: apache2Action 'start' failed.
The Apache error log may have more information.
 failed!

When I write tail /var/log/apache2/error.log.1, it returns my that message, between others:

[Fri Mar 10 11:25:03 2017] [error] [client 62.210.170.90] File does not exist: /var/www/mysql

The problem is that i don’t recognize this IP 62.210.170.90, and I don’t know why it’s registered in the log file.

This and other IP’s adresses are appearing at the log, and it’s not mine.

What can be happening?

Thx.

Well, for some reason i don’t really no, the error.log wais saying that apache2 was unable to access the errorlog file. I created the errorlog empty file at the local it seemed to be pointed (another one at /var/www/logs/error_log) and the server could now restart. Now the problem is solved.

To see what’s going on, if you can run:

tail -50 /var/log/apache2/error.log

… and paste the output in to a code block, we can take a look for you.

The error you’re seeing in line you pasted simply states that /var/www/mysql doesn’t exist as a file, which is why it was logged. As far as what was trying to access it, other that the IP logged, it’s hard to say without more information.

[....] Restarting web server: apache2Action 'start' failed.

When I type “tail /var/log/error.log.1”, i get this:

[Thu Mar 09 22:25:36 2017] [error] [client 151.80.134.210] File does not exist: /var/www/mysql

apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

That’s it. I believe it’s something malicious that cracked my server. I don’t recognize anyone of theses IP addresses.

Hope this information is helpful.
