MediaWiki Installation

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.

• Don't forget security updates! Keep an eye on the low-traffic release announcements mailing list.

An error occured while writing the config/LocalSettings.php file. Check user rights and disk space then try again.

Something's not quite right yet; make sure everything below is filled out correctly.

Installation successful!

To complete the installation, please do the following:

1. Download config/LocalSettings.php with your FTP client or file manager
2. Upload it to the parent directory
3. Delete config/LocalSettings.php
4. 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.
