Manual:Short URL/Apache/ja

These instructions help setup Short URLs on Apache. The LiteSpeed webserver is Apache compatible and can be configured in relatively the same way. For information on what Short URLs are or to get instructions on configuration for other servers see Manual:Short URL. If you don't know what webserver you're using since you're using some sort of web hosting service, it's very likely that your host is using Apache.

Plan
Before starting, you need to decide on the name of your virtual "short url" path.

In this manual we'll recommend/assume the following. Remember to use your own paths if they are different.
 * The MediaWiki directory is located at:
 * The desired short url format is:

These following instructions have been included in an automated wizard (requires MediaWiki 1.17 or later):
 * http://shorturls.redwerks.org/

If you just want your wiki configured quickly or you find the guide confusing then you may want to try that tool first. Please note, however, that it will not work on firewalled or private wikis. In the latter case, you can still try it out by making your wiki temporarily public by setting  to. Remember to change it back to  once you are done.

Otherwise, follow along.

Find the right file
The recommended way to set up short URLs in Apache is by editing the Apache config files. This requires that you have access to the server configuration. If you are on a shared host, you most likely don't and will need to use a  file instead. Using  files is less efficient and doesn't give you as much control when it comes to fancy setups with multiple domains but they are powerful enough to set up most short url configurations. LiteSpeed users should use the  method.

Use the instructions of one of the following two sections, depending on whether you have root access or need to use  instead.

Find the Apache configuration file (root access)
The correct config file to edit for root configs may be in one of a number of places.

Most linux distributions setup Apache with set of  folders setup. The correct config file to edit is the one in  where the configuration for your wiki has been setup. If you haven't set one up and are using the default  for your wiki setup then you can edit.

Don't forget to enable overrides by. It is disabled by default in Ubuntu 12.04 and Ubuntu 12.10.

If your distribution does not have those directories, then you should edit the Apache configuration file directly. This file should be at. Note that it used to be named, if you have a   and no   then   is the one you want to edit.

If your Apache config isn't in any of these spots you should consult the documentation for whatever system you used to install Apache, and find the location of the Apache configuration file.

If you're on a shared host without access to Apache config files you'll have to use a .htaccess file instead.

In an Apache config file you will likely have a VirtualHost block containing your wiki. If you do have one then that is the location where your rewrite rules will go. RewriteRule config does not inherit so don't put these config options in the global config if you are using a VirtualHost.

After you've setup the config as below inside Apache you're going to need to restart Apache to make it apply the new config.
 * If you are using Plesk or cPanel it should have a method of restarting the server.
 * From the command line the command is usually something like,  ,   or as on the latest Fedora releases  . These commands need to be run as root, usually by prefixing them with.

Where to put .htaccess
If you're using a  file you'll need to edit or create the file. Find the path that contains both your script path and your virtual path. Usually this means the top directory of your site, but let's look at a few examples:

Note that if you want to make a redirect from the main domain to your wiki's Main Page (e.g. http://example.org/ &rarr; http://example.org/wiki/Main_Page ). Then you always have to set up the .htaccess file in the top level, even if the other directories are nested deeper.

Setting up the rewrite rules
The first rule you'll need inside of your config is one to enable the rewrite engine:

Now we need a rule to make your article path a virtual path pointing to index.php. Be sure to replace  and   with the paths you choose in the beginning (if different).

If you are using a root url instead of a normal short url you will need to use the following instead (to ensure that existing files and directories are not seen as article, e.g. "/index.php" "/images" etc.):

Optionally, you can include a rule to show the Main Page on the path itself, to simplify navigation when people visit urls without a page title specified:

The end result should look something like this:

LocalSettings.php
We need to make the following configurations in LocalSettings.php:

If you get an "Internal error" page saying "Redirect loop detected!" after you finish configuration you may be using something other than mod_php. If so you need to explicitly turn on short urls using the following line in your LocalSettings.php:
