A virtual machine or a server that you can install the system onto.
This installation assumes that you have a database system already configured that you will also be using.
- Vmware virtual machine
- Centos 6.5
- Shared Mysql server with our own database
- ssh access to the server
You will need to manually step thru the wizard at the end to configure your mediawiki server.
Possibilities include:
- local users (i.e. only those with local accounts can access the system, you control who can create or self create accounts).
- ActiveDirectory integration
We use ActiveDirectory using the http://www.mediawiki.org/wiki/Extension:LDAP_Authentication. See the https://github.com/narath/medwiki/wiki/ActiveDirectory for some instructions on how to set this up (you will need to get some configuration settings from your ActiveDirectory admin).
We recommend the following permission settings within your wiki
# The following permissions were set based on your choice in the installer
$wgGroupPermissions['*']['createaccount'] = false;
# Disable editing by anonymous users
$wgGroupPermissions['*']['edit'] = false;
# Disable reading by anonymous users
$wgGroupPermissions['*']['read'] = false;
TODO: how to enable LDAP to give you email addresses so that users can receive notifications about watched pages.
If using a remote SMTP server, make sure you have enabled httpd to use network connections in SELinux. This is currently handled by the Puppet script (see task 'Enable Mediawiki to connect to remote smtp service').
Append to the LocalSettings file:
$wgSMTP = array(
'host' => "mail.example.com", // could also be an IP address. Where the SMTP server is located
'IDHost' => "example.com", // Generally this will be the domain name of your website (aka mywiki.org)
'port' => 25, // Port to use when connecting to the SMTP server
'auth' => true, // Should we use SMTP authentication (true or false)
'username' => "my_user_name", // Username to use for SMTP authentication (if being used)
'password' => "my_password" // Password to use for SMTP authentication (if being used)
);
sudo su
mkdir /etc/mediawiki
cd /var/www/mediawiki
mv LocalSettings.php /etc/mediawiki/LocalSettings.php
ln -s /etc/mediawiki/LocalSettings.php LocalSettings.php
cd /etc/mediawiki
git init .
git add .
git commit -m "Initial commit with barebones LocalSettings"
Copy the logo to /var/www/mediawiki/images
Ours is called logo.jpg

I had previously used FileExtension, but it broke recently in uploading Word files, so have not used it. Instead the current file uploading is reasonable once you have done it, so we use this instead.
See the https://github.com/narath/medwiki/wiki/Moving-your-wiki for some tips on moving from your prototype wiki to your production wiki.
The image we use uses SELinux, so you will need to follow the instructions here http://www.mediawiki.org/wiki/Manual:Configuring_file_uploads
Enable some additional file extensions
$wgFileExtensions = array('png','gif','jpg','jpeg','doc','xls','mpp','pdf','ppt','tiff','bmp','docx', 'doc', 'xlsx', 'pptx','ps','odt','ods','odp','odg');
Increase the size of file uploads to 5MB
vim /etc/php.ini
Change
upload_max_filesize = 2M
To
upload_max_filesize = 5M
We use the Mediawiki Foreground Skin to add reponsive layouts to our mediawiki installation.
sudo su
# navigate to the mediawiki skins directory
cd /opt/mediawiki/mediawiki-{version}/skins
# clone foreground skin from github repo
git clone https://github.com/thingles/foreground.git
# change ownership to apache
chown apache:apache /opt/mediawiki/mediawiki-{version}/skins -R
# Add the following lines to LocalSettings.php:
# require_once "$IP/skins/foreground/foreground.php";
vi /opt/mediawiki/mediawiki-{version}/LocalSettings.php
# Optionally, change the default skin to foreground for mobile devices (also in LocalSettings.php)
# if (preg_match("/(mobile|webos|opera mini)/i", $_SERVER['HTTP_USER_AGENT'])) {
# $wgDefaultSkin = 'foreground';
# } else {
# $wgDefaultSkin = 'vector';
# }
In addition to the standard vector and foreground skins we added supplimental styles to support responsive "panels" on the main wiki page. The wiki page https://github.com/narath/mediki/wiki/Additional-Styles---MediaWiki:Common.css shows the styles we used. These styles were added to /index.php/MediaWiki:Common.css page.
We added the Twitter Widget extension (http://www.mediawikiwidgets.org/Twitter) to our mediawiki installation. This extension has a dependency on the Widget extension (http://www.mediawiki.org/wiki/Extension:Widgets).
We first installed the Widget extension. We performed the follow steps starting from the mediawiki home diretory:
cd extensions
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/Widgets.git
cd Widgets
git submodule init
git submodule update
Then we added the follow instruction to the LocalSettings.php file:
require_once "$IP/extensions/Widgets/Widgets.php";
Then we changed the Widget extension file owership and granted read-write access to the web server to the Widgets/compliled_templates directory:
chown -R apache:apache /opt/mediawiki/mediawiki-{version}/extensions/Widgets
chmod -R 755 /opt/mediawiki/mediawiki-{version}/extensions/Widgets/compiled_templates
Then we then configured SELinux to allow the web server to write to the compiled_templates directory:
semanage fcontext -a -t httpd_sys_rw_content_t /opt/mediawiki/mediawiki-{version}/extensions/Widgets/compiled_templates
restorecon -v /opt/mediawiki/mediawiki-{version}/extensions/Widgets/compiled_templates
Next we declared the Twitter Widget by creating a new page called Widget.Twitter and adding the following content:
<noinclude>__NOTOC__
This widget allows you to embed a '''[http://twitter.com/widgets/html_widget Twitter feed]''' (HTML version) on your wiki page.
Created by [http://www.mediawikiwidgets.org/User:Sergey_Chernyshev Sergey Chernyshev]
== Using this widget ==
For information on how to use this widget, see [http://www.mediawikiwidgets.org/Twitter widget description page on MediaWikiWidgets.org].
== Copy to your site ==
To use this widget on your site, just install [http://www.mediawiki.org/wiki/Extension:Widgets MediaWiki Widgets extension] and copy [{{fullurl:{{FULLPAGENAME}}|action=edit}} full source code] of this page to your wiki as '''{{FULLPAGENAME}}''' article.
</noinclude><includeonly><a class="twitter-timeline" href="" data-widget-id="<!--{$id|escape:'html'}-->"></a>
<!--{counter name="twittercounter" assign="twitblogincluded"}--><!--{if $twitblogincluded eq 1}--><script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+"://platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script><!--{/if}--></includeonly>
Finally, we are able to embed the Twitter widget on any page with the following syntax:
{{#widget:Twitter|user=perfplanet|id=573172210619322368}}
We added the TopTenPages extension (http://www.mediawiki.org/wiki/Extension:TopTenPages) to our mediawiki installation.
We manually created the file TopTenPages.php in the /opt/mediawiki/mediawiki-{version}/extensions directory with the following contents:
<?php
# To install the extension, add to your LocalSettings.php:
# require_once("$IP/extensions/TopTenPages.php");
/*
Syntax:
<TopTenPages/>
<TopTenPages>5</TopTenPages>
<TopTenPages offset="1"/>
{{Special:TopTenPages}}
{{Special:TopTenPages/-/5}}
{{Special:TopTenPages/1/5}}
*/
$wgExtensionCredits['specialpage'][] = array(
'name' => 'TopTenPages',
'version' => '0.3.2',
'author' => array(
'Timo Tijhof',
'Sascha',
),
'url' => 'https://www.mediawiki.org/wiki/Extension:TopTenPages',
'description' => 'Shows most viewed pages.',
);
$wgAutoloadClasses['SpecialTopTenPages'] = __DIR__ . '/SpecialTopTenPages.php';
$wgSpecialPages['TopTenPages'] = 'SpecialTopTenPages';
$wgSpecialPageGroups['TopTenPages'] = 'other';
$wgExtensionFunctions[] = 'efTopTenPages';
# When including, always start the list numbering at one, even if offset was set.
# Defaults to false so that if (for example) offset is 1, the list will be numbered 2, 3, 4 ...
$wgttpAlwaysStartAtOne = false;
function efTopTenPages() {
global $wgParser;
$wgParser->setHook( 'TopTenPages', 'efTopTenPagesRender' );
}
/**
* The callback function for converting the input text to HTML output.
*/
function efTopTenPagesRender( $text, array $args, Parser $parser, PPFrame $frame ) {
if (array_key_exists('offset', $args)) {
$offset = (int) $args['offset'];
} else {
$offset = 0;
}
if ($text > 0){
$limit = (int) $text;
} else {
$limit = 10;
}
return $parser->recursiveTagParse( "{{Special:TopTenPages/$offset/$limit}}", $frame );
}
We added the following lines to the /opt/mediawiki/mediawiki-{version}/LocalSettings.php file:
require_once("$IP/extensions/TopTenPages.php");
$wgttpAlwaysStartAtOne = true;
The TopTenPages widget can now be added to any page by adding the <TopTenPages/> tag.
We use Google Calendar for this through the mediawiki HTMLet extension. HTMLets allow you to inject pre-defined HTML widgets into your mediawiki content.

Our backup script backups several disparate artifacts. We first perform a mysqldump of the mediawiki database, then we create a tarball which includes the mysqldump data, the entire mediawiki application, as well as the mediawiki configuration files located under the /etc/mediawiki directory.
The backup script then compresses the resulting tarball and gives it a date-stamped filename, for example, backup-201403111314.tgz. Then the compressed backup file is uploaded to our Amazon S3 bucket. The opensource AWS tools scripts are used to upload the backup file to Amazon S3, http://timkay.com/aws/. A sample backup script can be found here: https://github.com/narath/medwiki/wiki/Mediawiki-sample-backup-script.
We created a Google Group, [email protected], which you can subscribe to to receive information about vurnerabilities and security updates for the following brigopedia components:
- CentOS
- Mediawiki
It would nice to be able to subscribe to mailing lists for these items, as well, but we were not able to locate lists for these extensions:
- LDAPAuthentication
- VisualEditor
- Widgets extension
I'd welcome your thoughts and feedback on this. Just post your thoughts in the issues and I should see it there.
