What is an Apache Error?

An Apache error is a message generated by the Apache Web Server software and is usually a result of a coding issue or server misconfiguration. Apache errors may include Internal Server Error or 403 Forbidden messages. They can range from minor, easily fixed errors to more serious ones that may require support from a system administrator. Therefore, understanding the causes of Apache errors helps take the necessary steps to resolve the issue.

This article walks through solving the error: No matching DirectoryIndex (index.html) on CentOS 6 and 7 servers, logged in as root.

[SOLVED] Apache Error: No matching DirectoryIndex

General Reason for Apache Error

This error may occur when attempting to access applications that have an index.php file (or another index file), but not an index.html or other specified directory index file. For example, phpMyAdmin includes an index.php file upon installation, but not an index.html file.

Default Apache Configuration

By default, Apache is configured with the following.

<IfModule dir_module>
DirectoryIndex index.html

This configuration means that Apache will only look for directory index files that are named index.html. So, when attempting to access phpMyAdmin, Apache throws the following error.

[autoindex:error] [pid 20115] [client] AH01276: Cannot serve directory /usr/share/phpMyAdmin/: No matching DirectoryIndex (index.html) found, and server-generated directory index forbidden by Options directive

In this case, we want to add index.php to the DirectoryIndex directive. To do this, access the file from the text editor of your choice. This tutorial uses Vim.

vim /etc/httpd/conf/httpd.conf

DirectoryIndex File Changes

Locate the following configuration information within the configuration file.

<IfModule dir_module>
DirectoryIndex index.html

Make the following change to the file to add index.php to the directive.

<IfModule dir_module>
 DirectoryIndex index.html index.php

Save and Exit the File

Save and exit the file once the appropriate changes are made. For Vim, exit and save the file with the :wq command.

Restart Apache

Restart Apache to implement the changes.

systemctl restart httpd

Wrapping Up

Solving the No matching DirectoryIndex Apache error is straightforward with the proper knowledge and understanding of the error's underlying cause. Following this tutorial ensures the error is rectified easily.
