How to Fix “Could not reliably determine the server’s fully qualified domain name”

Question :
How to fix “Could not reliably determine the server’s fully qualified domain name” when starting apache httpd service ?

[root@centos64 ~]# service httpd start
Starting httpd: httpd: apr_sockaddr_info_get() failed for centos64.ehowstuff.local
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
                                                           [  OK  ]

Answer :

Step 1:

Update /etc/hosts and do server’s ip address resolvable to the fully qualified domain name(fqdn) or hostname.

[root@centos64 ~]# vi /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.2.62 centos64.ehowstuff.local

Step 2:

Restart apache httpd service :

[root@centos64 ~]# service httpd restart
Stopping httpd:                                            [  OK  ]
Starting httpd:                                            [  OK  ]
