No matching directoryindex index html found and server generated directory index forbidden

How to Solve Error Message AH01276: Cannot serve directory /: No matching DirectoryIndex (index.html,index.php) found, and server-generated directory index forbidden by Options directive

This article will discuss about how to solve an error message as exist in the title of this article itself. Basically, the context of this article is troubleshooting to solve why a web-based application using Yii framework is not working. The actual error message exist as follows :

AH01276: Cannot serve directory /folder-path-root-web-location/: No matching DirectoryIndex (index.html,index.php) found, and server-generated directory index forbidden by Options directive

The error above exist after searching the cause in the error log file of Apache Webserver. It is because in the default root folder of the web-based application using Yii framework there is no file with the name of ‘index.html’ or ‘index.php’. Actually, there is a reason for Apache Webserver looking for the ‘index.html’ or ‘index.php’ file for initial execution of the web-based application. The reason is available in the Apache Webserver’s virtual host web-based application configuration. The configuration itself can exist in the main Apache Webserver’s file configuration. But it can also exist in other file configuration focusing on the virtual host definition. The following is the configuration lines for virtual host definition in order to inform Apache Webserver about how to access the web-based application :

 ServerName localhost.webapps.web ServerAdmin webmaster@localhost.webapps.web DocumentRoot /var/www/html/webapps DirectoryIndex index.html index.php Options -Indexes +FollowSymLinks +MultiViews AllowOverride All Require all granted ErrorLog /var/www/html/webapps/logs/localhost.webapps.web-error.log CustomLog /var/www/html/webapps/logs/localhost.webapps.web-access.log combined 

As it is exist from the above line of configuration, there is a line as follows :

DirectoryIndex index.html index.php

The above line configuration means that index.html and index.php will be an index file in the root directory of the web-based application. So, the solution is simple. Just point of the root directory folder of the web-based application which contains the index.html or the index.php file. In the context of web-based application using Yii framework, it exist in the ‘web’ folder. So, change the DocumentRoot entry into the following line :

DocumentRoot /var/www/html/webapps/web

Make sure there is a file with the name of ‘index.html’ or ‘index.php’. Just check inside of the folder. Finally, don’t forget to restart the Apache Webserver’s service.

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.

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.

Исправляем 403 Forbidden в Apache на CentOS

Маленькая, но полезная заметка. Однажда, в один прекрасный день у нас перестала работать подмапленная в web — доступ директория (смонтирована она была через /etc/fstab ). Браузер возвращал 403 Forbidden Error. Не долго думая, смотрим, что происходит в логах при обращении к web. В режиме реального времени можно посмотреть командой:

tail -f /var/log/httpd/error_log

Итак, у нас там было следующее:

AH01276: Cannot serve directory /var/www/html/merion_directory/: No matching DirectoryIndex (index.html,index.php) found, and server-generated directory index forbidden by Options directive

Хм. Дело в том, что у нас там просто выводится список папок, по файлам. Следовательно, сервак просто не может отрисовать эту структуру. Погнали исправлять

Воркэраунд

Лезем в конфигурационный файл нашего Apache:

vim /etc/httpd/conf/httpd.conf

И в общей области, где идут настройки директорий добавляем следующее:

 Options Indexes FollowSymLinks 

Где merion_directory — ваша директория в корне веб — сервера /var/www/html/, при обращении к которой вы получаете 403. Конфигурация проста — мы просто говорим апачу, что у нас там каталог файлов и его нужно «отрисовать» даже несмотря на то, что у нас там нет никаких index.html или index.php. По окончанию настройки ребуетаем Apache:

Или через systemctl. Ребутаем браузер (Ctrl + F5). Профит!
