Troubleshoot Apache can't start after enabled LDAP Authentication

You may see the follwing message on Deki VM (8.05.1 I used), and Apache can't start.

dekiwiki:/etc/apache2# /etc/init.d/apache2 start
 * Starting web server (apache2)...
apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
   ...done.

You can consider to move "localhost" entry after "dekiwiki" as described below, in /etc/hosts file.

dekiwiki:/etc/apache2# vi /etc/hosts

#127.0.0.1      localhost
127.0.0.1       dekiwiki.localdomain    dekiwiki        localhost

Then Apache2 can start, in my case.

dekiwiki:/etc/apache2# /etc/init.d/apache2 start
 * Starting web server (apache2)...
   ...done.
