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

Question

I tried to restart my Apache server on CentOS 5.0 and got this message:

httpd: Could not reliably determine the server\'s fully qualified domain name,

Answer 1

Make sure you're editing the right httpd.conf file, then the error about unreliable server's domain name should be gone (this is the most common mistake).

To locate your httpd.conf Apache configuration file, run:

apachectl -t -D DUMP_INCLUDES

Then edit the file and uncomment or change ServerName line into:

ServerName localhost

Then restart your apache by: sudo apachectl restart
