Could not reliably determine the server's fully qualified domain name

Question

I have just installed Apache 2.2.17, and I am using it for the first time.

Now when I try to start the server using the command service httpd start it gives me the message:

httpd: Could not reliably determine the server's fully qualified domain name, using ::1 for ServerName

Now I think I have to set ServerName and the IP address as I search through Google. But I don't know in which file I have to set.

How can I fix this problem?

On my RPi I had to put the httpd.conf file in /etc/apache2/conf.d for it to work. – samkass Apr 12 '13 at 02:25
Using Ubuntu 13.04, I had to put it into /etc/apache2/conf.d/httpd.conf as well, nothing else worked... – user1853181 Jan 30 '14 at 14:13
Thank you this resolved my issue as well. I recently set the actual hostname in /etc/hosts and this broke apache until I set ServerName localhost in the global context. Now the vhost is working again and the SSL cert is being served properly. – AaronM Oct 12 '15 at 16:07
In my case I edited ```/etc/apache2/apache2.conf``` – Vagabond Jan 27 '21 at 14:32

Yes, you should set ServerName:

http://wiki.apache.org/httpd/CouldNotDetermineServerName

http://httpd.apache.org/docs/current/mod/core.html#servername

You can find information on the layouts used by the various httpd distributions here:

http://wiki.apache.org/httpd/DistrosDefaultLayout

In your case the file to edit is /etc/httpd/conf/httpd.conf

I was NOT getting the ServerName wrong. Inside your VirtualHost configuration that is causing this warning message, it is the generic one near the top of your httpd.conf which is by default commented out.

Change

#ServerName www.example.com:80

to:

  ServerName 127.0.0.1:80

Under Debian Squeeze;

Edit Apache2 conf file : vim /etc/apache2/apache2.conf
Insert the following line at the apache2.conf: ServerName localhost
Restart Apache2: apache2ctl restart or /etc/init.d/apache2 restart

Should work fine (it did solve the problem in my case)

tks noodl for the link on the different layouts. :)

Another option is to ensure that the full qualified host name (FQDN) is listed in /etc/hosts. This worked for me on Ubuntu v11.10 without having to change the default Apache configuration.

" To solve this problem You need set ServerName.

1: $ vim /etc/apache2/conf.d/name For example set add ServerName localhost or any other name:

2: ServerName localhost Restart Apache 2

3: $ service apache restart For this example I use Ubuntu 11.10.1.125"

FQDN means the resolved name over DNS. It should be like "server-name.search-domain".

The warning you get just provides a notice that httpd can not find a FQDN, so it might not work right to handle a name-based virtual host. So make sure the expected FQDN is registered in your DNS server, or manually add the entry in /etc/hosts which is prior to hitting DNS.

If you are using windows there is something different sort of situation

First open c:/apache24/conf/httpd.conf. The Apache folder is enough not specifically above path

After that you have to configure httpd.conf file.

Just after few lines there is pattern like:

#Listen _____________:80
Listen 80

Here You have to change for the localhost.

You have to enter ipv4 address for that you can open localhost.

Refer this video link and after that just bit more.

Change your environment variables:

Image for Environment USER Variables in System setting

In which you have to enter path:

c:apache24/bin

and
same in the SYSTEM variables

Image is for system variables path

If any query feel free to ask.

Two things seemed to do it for me:

Put all aliases for 127.0.0.1 in /etc/hosts in a single line (e.g. 127.0.0.1 localhost mysite.local myothersite.local
Set ServerName in my httpd.conf to 0.0.0.0 (localhost or 127.0.0.1 didn't work for me)

Editing /etc/hosts got rid of long response times and setting the ServerName got rid of OP's warning for me.

If you are using windows, remove comment on these lines and set them as:

Line 227 : ServerName 127.0.0.1:80 
Line 235 : AllowOverride all 
Line 236 : Require all granted

Worked for me!

I had another service running on port 80 (organizr) so I had to modify the listener port (line 60). Also added firewall rule but not required. ``` Listen 4444 ``` I had to do some digging to find an answer.

Here's my two cents. Maybe it's useful for future readers.

I ran into this problem when using Apache within a Docker container. When I started a container from an image of the Apache webserver, this message appeared when I started it with docker run -it -p 80:80 my-apache-container.

However, after starting the container in detached mode, using docker run -d -p 80:80 my-apache-container, I was able to connect through the browser.

I am using ubuntu 22.04

I installed the apache2 at the location '/usr/local/apache2'

I just edited the '/usr/local/apache2/conf/httpd.conf' file.

run the following commands

cd /usr/local/apache2/conf

sudo nano httpd.conf

find this comment

#ServerName www.example.com:80, in my case it is at line 197

after that add this

ServerName localhost

don't modify anything else in this file!

Thank you!

Try to do it.

hostnamectl set-hostname youfirstdomain.com

vi /etc/hosts

add this line

0.0.0.0 youfirstdomain.com

Instead of 0.0.0.0 put your IP address of the server

sudo systemctl restart apache2
