Page Linking Help Needed
Hi, is there a plugin that automatically links key words to other Wiki pages? At the moment I am manually creating links but I'm sure there must be another way?

Any help would be much appreciated!

Mediawiki Appliance Version 1.13.20 Problems
Downloaded rPath Mediawiki Appliance, Running it on VMwear PLayer but can't find the localsettings.php file to edit.

Can't find much documentation. Any help or documentation would be great!

Extension Licensing Guidelines
I was wondering if there were licensing guidelines for extensions. I am combined several extensions with MediaWiki and noticed that some of the extensions have licenses that are incompatible with other extensions (e.g. Affero v.3 with a majority of extensions under GPL v.2). There are also several extensions that have no license indicated--is there a default license if you are coding for combination with MediaWiki? I was wondering if there was already guidance or if there could be some written on these topics. Thanks.

mySQL database username

 * MediaWiki version: 1.15.1
 * PHP version: 5.2.9
 * MySQL version: 5.1.33

I am configuring MediaWiki, except the one part I am having problems with is when it is asking me for a database username and password and confirm password. Below that is the superuser account, which is root.

>>>''Granting user permissions... Query "GRANT DELETE,INSERT,SELECT,UPDATE,CREATE TEMPORARY TABLES ON `wikidb`.* TO 'username'@'%' IDENTIFIED BY 'password' " failed with error code "Can't find file: 'user' (errno: 2) (localhost)".'' <<<<

But it will not let me continue the configuration unless I specify a user and password since it will not let me leave it blank.

I am installing on Windows XP, just need some help with this issue. I am not very familiar with databases, i know the root user account info, but it is asking for a username and password and confirm password.

Any help would be much appreciated.

Installation of Mediawiki without web forms

 * MediaWiki version: 1.15.2
 * PHP version: 5.2.12
 * MySQL version: 5.2.12

Since I have, generated all in one place, the answers requested on the MediaWiki install form, I would like to install new instances of MediaWiki
 * without using the form manually
 * without driving the form programatically (with, say, )
 * without hacking
 * without reverse-engineering my own install script which calls into parts of MediaWiki to set it up

Isn't there a stable, maintained entrypoint for this? Shouldn't there be?

P.S. Apologies in advance if the answer to this is addressed elsewhere, or is otherwise obvious

Install failing to connect to MySQL instance

 * MediaWiki version: 1.15.2
 * PHP version: 5.3.2
 * MySQL version: 5.1.45
 * URL: Sorry, it's on my laptop, not the web. :-(

I'm having a problem installing MediaWiki on Windows 7. I did it all OK last week on Windows XP. (They are both in VMs under VMware Fusion on my MacBook.) The problem is in connecting to MySQL: "Attempting to connect to database server as root...failed with error [2002] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond."

The full install output is:

I am setting the passwords correctly. MySQL is running OK and I can connect to it using the same password I am giving MediaWiki. I have tried opening a firewall hole for the MySQL port and TCP/IP is enabled. In attacking the problem I have uninstalled and reinstalled MySQL several times and PHP once... I'm about out of ideas. :-(

Site config

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

Contact e-mail: 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.

Copyright/license: No license metadata Public Domain GNU Free Documentation License 1.2 (Wikipedia-compatible) GNU Free Documentation License 1.3 A Creative Commons license - choose A notice, icon, and machine-readable copyright metadata will be displayed for the license you pick.

Admin username: Password: Password confirm: 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.

The password cannot be the same as the username.

Object caching: No caching DBA (not recommended) Memcached Memcached servers: An object caching system such as memcached will provide a significant performance boost, but needs to be installed. Provide the server addresses and ports in a comma-separated list.

MediaWiki can also detect and support eAccelerator, Turck MMCache, APC, and XCache, but these should not be used if the wiki will be running on multiple application servers.

DBA (Berkeley-style DB) is generally slower than using no cache at all, and is only recommended for testing.

E-mail, e-mail notification and authentication setup

E-mail features (global): Enabled Disabled 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: Enabled Disabled 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: Disabled Enabled for changes to user discussion pages only Enabled for changes to user discussion pages, and to pages on watchlists (not recommended for large wikis) 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: Disabled Enabled 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: MySQL PostgreSQL SQLite Database host: If your database server isn't on your web server, enter the name or IP address here.

Database name: DB username:Check username DB password:and password DB password confirm: 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: Use superuser account Superuser name: Superuser password: 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.

MySQL specific options Database table prefix: 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. Storage Engine Select one: InnoDB MyISAM InnoDB is best for public web installations, since it has good concurrency support. MyISAM may be faster in single-user installations. MyISAM databases tend to get corrupted more often than InnoDB databases.

Database character set Select one: MySQL 4.1/5.0 binary MySQL 4.1/5.0 UTF-8 MySQL 4.0 backwards-compatible UTF-8 This option is ignored on upgrade, the same character set will be kept.

WARNING: If you use backwards-compatible UTF-8 on MySQL 4.1+, and subsequently back up the database with mysqldump, it may destroy all non-ASCII characters, irreversibly corrupting your backups!.

In binary mode, MediaWiki stores UTF-8 text to the database in binary fields. This is more efficient than MySQL's UTF-8 mode, and allows you to use the full range of Unicode characters. In UTF-8 mode, MySQL will know what character set your data is in, and can present and convert it appropriately, but it won't let you store characters above the Basic Multilingual Plane.

After installing XAMPP and starting the 3 servers, I extracted the files from the Mediawiki .tar file (mediawiki-1.15.3), placed them into a folder I named "Mediawiki" and moved the folder in the htdocs folder. Then I changed the attributes of the config folder in the Mediawiki folder with 'chmod' to allow everything (chmod a+w config). I defined a new database and allowed all the privileges to it. - All these procedures I performed according to the instructions at the site: http://techjournal.318.com/web-development/installing-mediawiki-on-mac-os-x/ When browsing to the http://localhost/mediawiki/config/index.php, I fed all the parameters required but still received the message: "Something's not quite right yet; make sure everything below is filled out correctly"
