How do i set up the server's fully qualified domain name?

Question

When i try to restart apache issueing /etc/init.d/apache2 restart i get the following messages:

root@server:~# /etc/init.d/apache2 restart
 * Restarting web server apache2                                                                                                                             apache2: apr_sockaddr_info_get() failed for server

root@server:~# hostname -f
hostname: Name or service not known
root@server:~# cat /etc/hosts
127.0.0.1     localhost localhost.localdomain
108.1.*.*     eins
root@server:~#

Note:the two asterisk at the end of ip in /etc/hosts are added by me at the time of posting. Note2: let's say my domain name is www.xyz.net

I would like to know exactly what i must do step by step please. Thank's very much!

Answer 1

Just edit the blank httpd.conf for Apache with the following:

sudo gedit /etc/apache2/httpd.conf

Add the line:

ServerName localhost

Save and quit and restart Apache:

sudo /etc/init.d/apache2 restart

That will take care of it.

Answer 2

Edit you hosts file

sudo nano /etc/hosts

look if you ip 127.0.1.1 as the good name of the server

127.0.1.1      srv-web-01

and restart your Apache

sudo service apache2 restart

Answer 3

1) Edit the file: vi /etc/apache2/apache.conf 2) Write in the last line (to see your-machine-name write: cat /etc/hostname): ServerName your-machine-name 3)service apache2 reload

enjoyit!
