[CentOS]Starting Apache server gives error -"Could not reliably determine the server's fully qualified domain name"

Did you ever come a cross a situation of getting this error??

I got :) Actually I have installed Apache on a CentOS server and I wanted to start it. So I used the following command on a Putty, i.e the SSH Client I have used to connect to the server. 

cmd -> sudo service httpd restart

output ->

Stopping httpd:                                 [  OK  ]

Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using 10.157.1.134 for ServerName

                                                           [  OK  ]

So I was unable to start the Apache server. So I checked why I got this error. And I again tired for the command httpd, to check whether the server can identify the service,

cmd -> httpd

output -> httpd: Could not reliably determine the server's fully qualified domain name, using

10.157.1.134 for ServerName

(98)Address already in use: make_sock: could not bind to address [::]:80

(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80

no listening sockets available, shutting down

Unable to open logs

According to the error message I got, it pointed out the error, that is, it can not determine the domain name. So I have checked the Apache httpd.conf  file. 

cmd -> vim /etc/httpd/conf/httpd.conf

And checking through it, I have found out that there was actually no qualified server name under the section #ServerName . So I have added the server name i wanted and it was like this. 

previous -> #ServerName www.example.com:80

new -> ServerName 10.157.1.134:80

And I have tried the Apache restart command again and it  worked as expected. :) 

cmd -> /etc/init.d/httpd restart

output -> 

Stopping httpd:                                          [  OK  ]

Starting httpd:                                            [  OK  ]

Hope this will help some one else too !! :)

cheers!
