title: restart the apache server though putty
body: <p>I am new in linux. I have the server details. I am accessing this server through putty. I want to restart the server. After login the server I typed &quot; sudo apachectl restart&quot; after that it asked the password and after giving that I got &quot;apache2: Could not reliably determine the server's fully qualified domain name, using 202.136.40.61 for ServerName&quot;. For kind information,I have not the superuser's password. So shall I restart the server?</p>
