Can't write config file, aborting

In order to configure the wiki you have to make the config subdirectory writable by the web server. Once configuration is done you'll move the created LocalSettings.php to the parent directory, and for added safety you can then remove the config subdirectory entirely.

To make the directory writable on a Unix/Linux system:

	cd /path/to/wiki
	chmod a+w config

Afterwards retry to start the setup.

Site config

Preferably a short word without punctuation, i.e. "Wikipedia".
Will appear as the namespace name for "meta" pages, and throughout the interface.

Displayed to users in some error messages, used as the return address for password reminders, and used as the default sender address of e-mail notifications.

Language:

Select the language for your wiki's interface. Some localizations aren't fully complete. Unicode (UTF-8) is used for all localizations.

A notice, icon, and machine-readable copyright metadata will be displayed for the license you pick.

An admin can lock/delete pages, block users from editing, and do other maintenance tasks.
A new account will be added only when creating a new wiki database.

Shared memory caching:

"; aField( $conf, "Shm", "Turck MMCache", "radio", "turck" ); echo "
"; aField( $conf, "Shm", "APC", "radio", "apc" ); echo "
"; aField( $conf, "Shm", "eAccelerator", "radio", "eaccel" ); echo "

Using a shared memory system such as Turck MMCache, APC, eAccelerator, or Memcached will speed up MediaWiki significantly. Memcached is the best solution but needs to be installed. Specify the server addresses and ports in a comma-separated list. Only use Turck shared memory if the wiki will be running on a single Apache server.

E-mail, e-mail notification and authentication setup

E-mail features (global):

Use this to disable all e-mail functions (password reminders, user-to-user e-mail, and e-mail notifications) if sending mail doesn't work on your server.

User-to-user e-mail:

The user-to-user e-mail feature (Special:Emailuser) lets the wiki act as a relay to allow users to exchange e-mail without publicly advertising their e-mail address.

E-mail notification about changes:

For this feature to work, an e-mail address must be present for the user account, and the notification options in the user's preferences must be enabled. Also note the authentication option below. When testing the feature, keep in mind that your own changes will never trigger notifications to be sent to yourself.

There are additional options for fine tuning in /includes/DefaultSettings.php; copy these to your LocalSettings.php and edit them there to change them.

E-mail address authentication:

If this option is enabled, users have to confirm their e-mail address using a magic link sent to them whenever they set or change it, and only authenticated e-mail addresses can receive mails from other users and/or change notification mails. Setting this option is recommended for public wikis because of potential abuse of the e-mail features above.

Database config

Database type: $errs[DBpicktype]\n"; ?>

If your database server isn't on your web server, enter the name or IP address here.

If you only have a single user account and database available, enter those here. If you have database root access (see below) you can specify new accounts/databases to be created. This account will not be created if it pre-exists. If this is the case, ensure that it has SELECT, INSERT, UPDATE, and DELETE permissions on the MediaWiki database.

Superuser account: checked="checked" /> Use superuser account

If the database user specified above does not exist, or does not have access to create the database (if needed) or tables within it, please check the box and provide details of a superuser account, such as root, which does.

If you need to share one database between multiple wikis, or between MediaWiki and another web application, you may choose to add a prefix to all the table names to avoid conflicts.

Avoid exotic characters; something like mw_ is good.

Database charset

Select one:

EXPERIMENTAL: You can enable explicit Unicode charset support for MySQL 4.1 and 5.0 servers. This is not well tested and may cause things to break. If upgrading an older installation, leave in backwards-compatible mode.

The username specified above (at "DB username") will have its search path set to the above schemas, so it is recommended that you create a new user. The above schemas are generally correct: only change them if you are sure you need to.

Installation successful!

To complete the installation, please do the following:

Download config/LocalSettings.php with your FTP client or file manager
Upload it to the parent directory
Delete config/LocalSettings.php
Start using your wiki!

If you are in a shared hosting environment, do not just move LocalSettings.php remotely. LocalSettings.php is currently owned by the user your webserver is running under, which means that anyone on the same server can read your database password! Downloading it and uploading it again will hopefully change the ownership to a user ID specific to you.

EOT; } else { echo "

Installation successful! Move the config/LocalSettings.php file into the parent directory, then follow this link to your wiki.
