Edit the httpd.conf file and locate the DirectoryIndex in the back with a index.php.
For example, I changed the DirectoryIndex line to: DirectoryIndex index.html index.htm index.php Index.html.var
Save the edited content and restart Apache to do so.
DirectoryIndex index.html index.htm index.php index.php3
If the above settings still cannot run the first page in sequence, then you have to modify the PHP-related configuration file php.conf
In the/etc/httpd/conf.d/php.conf file
DirectoryIndex index.php
Above is even index.php priority, if the DirectoryIndex index.php removed, then index.html, should also be changed to DirectoryIndex index.html or DirectoryIndex Index.html index.php
The above describes the Apache: Set the first page run indexhtml indexphp order, including the Apache aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
