====== Apache - Troubleshooting - apr_sockaddr_info_get() failed ======

===== Error =====

<code bash>
service apache2 restart
</code>

returns:

<code>
AH00557: apache2: apr_sockaddr_info_get() failed for blogs
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1. Set the 'ServerName' directive globally to suppress this message
</code>

===== Fix =====

This error is usually harmless.


A quick solution to this problem:

<code bash>
sudo vi /etc/apache2/apache2.conf
</code>


<file bash /etc/apache2/apache2.conf>
# Insert at the end of the file
ServerName localhost
</file>

<WRAP info>
**NOTE:**  Sometimes a complex **/etc/hosts** file is required that includes all your virtual hosts.

<file bash /etc/hosts>
172.0.0.1 localhost.localdomain localhost
127.0.1.1 blogs
</file>


</WRAP>

----

===== Restart Apache =====

<code bash>
service apache2 restart
 * Restarting web server apache2 [ OK ]
