Mediawiki

Install on Ubuntu

• ASSUMPTION: MySQL is already installed
• install the following packages:

apt-get install imagemagick php5-cli php5-fpm php5-mysql

• If you are running nginx under a separate deploy user, you will need to edit /etc/php5/fpm/pool.d/www.conf and change the user for listen.owner and listen.group

Upgrade from tarball

• read all Release Notes
• download new tarball from http://www.mediawiki.org/wiki/Download
• unpack in deploy@linode2:wiki/
• copy over LocalSettings.php (which is a pointer to ~/wiki/var/LocalSettings.php)
• make images point to ../var/images
• in extensions, make links to folders in ~/wiki/var/extensions
• make a link to your ../var/my-logo-image.png file (and make sure $wgLogo matches in LocalSettings.php)
• run the database update script:

php maintenance/update.php

Increase the maximum upload file size

• Edit /etc/php5/apache2/php.ini to change this line:

; Maximum allowed size for uploaded files.
upload_max_filesize = 200M

• restart apache

Allow additional file types for upload

• Edit /etc/mediawiki/LocalSettings.php and add something like this:

$wgFileExtensions = array('png', 'gif', 'jpg', 'jpeg', 'doc', 'xls', 'pdf', 'txt');

Add your own logo image

• create a 135x135-pixel logo image and save as png
• copy the png file to /var/lib/mediawiki1.10/skins/common/images
• edit /etc/mediawiki1.10/LocalSettings.php to include this line:

$wgLogo = "/mediawiki/skins/common/images/mylogo.png";

Clean up the navigation sidebar

• log in as the admin user
• edit the wiki page http://localhost/mediawiki/index.php/MediaWiki:Sidebar

Lowercase Page Titles

• This helps you fix the titles of pages like "iPhone" that mediawiki automatically converts to "IPhone".
• install and enable the ParserFunctions extension:

apt-get install mediawiki-extensions (if not already installed)
mwenext ParserFunctions.php

• open the page Template:Lowercase_title for editing.
• add this code:

<span>{{DISPLAYTITLE:{{#if:{{NAMESPACE}}|{{NAMESPACE}}:|}}{{lcfirst:{{PAGENAME}}}}}}</span><noinclude>
{{documentation}}
</noinclude>

This can be found on Wikipedia: http://en.wikipedia.org/w/index.php?title=Template:Lowercase_title&action=edit

• add this line to the top of each affected page:

{{lowercase title}}

Syntax highlighting

Use the GeSHi extension included with mediawiki-extensions: http://www.mediawiki.org/wiki/Extension:SyntaxHighlight_GeSHi

Custom edit buttons

• download the icons you want to use: http://commons.wikimedia.org/wiki/Mediawiki_edit_toolbar
• download the icons in the images tree and find out where they ended up
• open the MediaWiki:Common.js page on your wiki for editing and add something like this

if (mwCustomEditButtons) {
 
   mwCustomEditButtons[mwCustomEditButtons.length] = {
     "imageFile": "images/2/23/Button_code.png",
     "speedTip": "inline <code> tag",
     "tagOpen": "<code>",
     "tagClose": "</code>",
     "sampleText": "Insert code here"};
 
  mwCustomEditButtons[mwCustomEditButtons.length] = {
     "imageFile": "images/3/3c/Button_pre.png",
     "speedTip": "block <pre> tag",
     "tagOpen": "<pre>\n",
     "tagClose": "\n</pre>",
     "sampleText": "Insert code here"}
}

• hold down the shift key and hit refresh on the browser to get the page to completely reload

Delete History

• Make sure the php5-cli package is installed.
• cd to /usr/share/mediawiki/maintenance
• run this:

sudo php deleteOldRevisions.php --delete

Back up the wiki

Use a command like this to dump the wiki database to a flat file:

/usr/bin/mysqldump --opt -u barney -pXXXXXXXX wikidb > /backup/wikidb.sql

May need this command in mysql to get it to work:

grant lock tables on *.* to barney@localhost;
flush privileges;

OLD
