index.php not loading by default

问题

I have just installed CentOS, Apache and PHP. When I visit my site http://example.com/myapp/, it says \"forbidden\". By default it\'s not loading the index.php file.

When I visit http://example.com/myapp/index.php, it works fine.

Any idea how to fix that issue?

回答1:

Apache needs to be configured to recognize index.php as an index file.

The simplest way to accomplish this..

1. Create a .htaccess file in your web root.

2. Add the line...

DirectoryIndex index.php

Here is a resource regarding the matter...
http://www.twsc.biz/twsc_hosting_htaccess.php

Edit: I'm assuming apache is configured to allow .htaccess files. If it isn't, you'll have to modify the setting in apache's configuration file (httpd.conf)

回答2:

While adding 'DirectoryIndex index.php' to a .htaccess file may work,

NOTE:

In general, you should never use .htaccess files

This is quoted from http://httpd.apache.org/docs/1.3/howto/htaccess.html
Although this refers to an older version of apache, I believe the principle still applies.

Adding the following to your httpd.conf (if you have access to it) is considered better form, causes less server overhead and has the exact same effect:

<Directory /myapp>
DirectoryIndex index.php
</Directory>

At a guess I'd say the directory index is set to index.html, or some variant, try:

DirectoryIndex index.html index.php

This will still give index.html priority over index.php (handy if you need to throw up a maintenance page)

This might be helpful to somebody. here is the snippet from httpd.conf (Apache version 2.2 windows)

# DirectoryIndex: sets the file that Apache will serve if a directory
# is requested.
#
<IfModule dir_module>
    DirectoryIndex index.html
    DirectoryIndex index.php
</IfModule>

now this will look for index.html file if not found it will look for index.php.

回答5:

Try creating a .htaccess file with the following

DirectoryIndex index.php

Edit: Actually, isn't there a 'php-apache' package or something that you're supposed to install with both of them?

回答6:

I had same problem with a site on our direct admin hosted site. I added

DirectoryIndex index.php

as a custom httd extension (which adds code to a sites httpd file) and the site then ran the index.php by default.

回答7:

For info : in some Apache2 conf you must add the DirectoryIndex command in mods_enabled/dir.conf (it's not located in apache2.conf)

回答8:

After reading all this and trying to fix it, I got a simple solution on ubuntu forum (https://help.ubuntu.com/community/ApacheMySQLPHP). The problem lies with libapache2-mod-php5 module. Thats why the browser downloads the index.php file rather than showing the web page. Do the following. If sudo a2enmod php5 returns module does not exist then the problem is with libapache2-mod-php5. Purge remove the module with command sudo apt-get --purge remove libapache2-mod-php5 Then install it again sudo apt-get install libapache2-mod-php5

回答9:

I had a similar symptom. In my case though, my idiocy was in unintentionally also having an empty index.html file in the web root folder. Apache was serving this rather than index.php when I didn't explicitly request index.php, since DirectoryIndex was configured as follows in mods-available/dir.conf:

DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm

That is, 'index.html' appears ahead of 'index.php' in the priority list. Removing the index.html file from the web root naturally resolved the problem. D'oh!

回答10:

Step by step and Full instruction for Ubuntu 16.04.4 LTS and Apache/2.4.18

"sudo -s"

"cd /etc/apache2/mods-enabled"

"vi dir.conf" and move index.php to right after DirectoryIndex like below and save file then restart apache server.

DirectoryIndex index.php index.html index.cgi index.pl index.xhtml index.htm

"service apache2 restart"

If you do not see dir.conf then you will need to load it (google for how to)

Done.

This post might be old but i am just posting it incase it helps some other person, I would not advise to Create a .htaccess file in your web root and change the index. I feel it is better to follow the steps

1. Go to the conf folder of your apache folder mine is

   C:\Apache24\conf

2. Open the file named

   httpd.conf

3. Go to the section

   <IfModule dir_module>
      DirectoryIndex index.html 
   
    </IfModule>
   

4. Add index.php to it as shown below

    <IfModule dir_module>
     DirectoryIndex index.html index.php
   
   </IfModule>
   

This way, it still picks index.html and index.php as the default index but giving priority to index.html because index.html came before *index.php. By this I mean in you have both index.html and index.php in the same directory, the index.html will be used as the default index except you write **index.php* before index.hml

I hope it helps someone... Happy Coding

This one works like a charm!

First

<IfModule dir_module>
    DirectoryIndex index.html
     DirectoryIndex index.php
</IfModule>

then after that from

<Files ".ht*">
    Require all denied
</Files>

to

 <Files ".ht*">
    Require all granted
</Files>

Same issue for me. My solution was that mod_dir was not enabled and apache2 was not issuing an error when reading the directive in my VirtualHost file:

DirectoryIndex index.html

Using the commands:

sudo a2enmod dir
sudo sudo service apache2 restart

Fixed the issue.
