  • MediaWiki will be installed on Linux (Fedora) in /opt/mediawiki directory with Apache web server and MariaDB database server. Suppose you have root access to the server. MediaWiki will be used "pretty URL" Short URL page address. Download latest MediaWiki tarball and unpack to /opt directory.
$ tar -xzf mediawiki-*.tar.gz -C /opt/
$ chown -R root:root /opt/mediawiki-*/
$ ln -s /opt/mediawiki-*/ /opt/mediawiki

$ wget -nc -P /etc/httpd/conf.d/
$ systemctl restart httpd.service
  • You can create your database and user in setup process by running the supplied configuration script (see bellow), but prefer create wiki MariaDB database and user manually (or using phpMyAdmin). It will be more general, useful especially in the future (backup, moving or reinstall wiki). Warning: delete .mysql_history file after running these commands (history store the password).
$ mysql -h localhost -u root
MariaDB [(none)]> CREATE DATABASE my_wiki;
MariaDB [(none)]> CREATE USER 'wikiuser'@'localhost' IDENTIFIED BY 'sql_wiki_passwd';   # change password
MariaDB [(none)]> GRANT ALL PRIVILEGES ON my_wiki.* TO 'wikiuser'@'localhost' WITH GRANT OPTION;

  • Press on continue and you will begin the installation of MediaWiki. Only now MediaWiki installer store settings in LocalSettings.php file and populate my_wiki MariaDB database.
  • Download generated file LocalSettings.php and move this file to the main wiki directory /opt/mediawiki.
$ mv LocalSettings.php /opt/mediawiki
$ chmod 600 /opt/mediawiki/LocalSettings.php   # contains $wgDBpassword
$ chown apache:apache /opt/mediawiki/LocalSettings.php


The LocalSettings.php file provides local configuration settings (based on the DefaultSettings.php file) of a MediaWiki.

$wgServer               = "";
$wgLogo                 = "$wgScriptPath/images/strela_logo.png";
$wgFavicon              = "$wgScriptPath/images/strela_icon.png";
$wgShowExceptionDetails = true;

Short URL

$wgScriptPath  = "/mediawiki";
$wgArticlePath = "/wiki/$1";
$wgUsePathInfo = true;
$ wget


File uploads

Uploaded files will be distributed into sub-directories of $wgUploadDirectory (/opt/mediawiki/images/) based on the first two characters of the md5 hash of the filename ($IP/images/a/ab/foo.jpg). If $wgHashedUploadDirectory is false, all images are uploaded in $wgUploadDirectory itself ($IP/images/foo.jpg)

$ chown -R apache:apache /opt/mediawiki/images/
$ chmod -R 755 /opt/mediawiki/images/
$wgEnableUploads       = true;
$wgFileExtensions[]    = "svg";

$wgAllowExternalImages = true;

MediaWiki supports SVG image rendering automatically be rendered as a PNG file. Direct SVG display is not supported in MediaWiki by default, unless you install NativeSvgHandler extension

$wgGroupPermissions['*']['createaccount'] = false;   # restrict account creation
$wgGroupPermissions['*']['edit']          = false;   # restrict anonymous editing
$wgEnableEmail                            = true;

  • Backup MediaWiki (MySQL database + images + LocalSettings.php + others) script Execute as root user (needed permissions to read LocalSettings.php file)
$ wget



Ensure that your "fresh install" consists of the same version of MediaWiki

  1. Backup Backup the database and MediaWiki files
  2. Install Re-create the database, user and permissions
    • create database username: wikiuser with database password: 'sql_wiki_passwd'
    • create database name: strela_wiki with all privileges for wikiuser
$ mysql -u root -p
MariaDB [(none)]> CREATE DATABASE strela_wiki;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON strela_wiki.* TO 'wikiuser'@'localhost' IDENTIFIED BY 'sql_wiki_passwd';
  1. Move
    1. Modify (created file) / copy (previous wiki settings) file LocalSettings.php
      $ chmod 600 LocalSettings.php; chown apache:apache LocalSettings.php
    2. Import the MediaWiki files (copy all MediaWiki files, images/math, images/thumb, images/tmp)
      $ chown -R apache:apache images/; chmod -R 755 images/
    3. Import the database backup
      $ mysql --user=wikiuser --password strela_wiki < strela_wiki-dump_YYYY-MM-DD.sql
    4. Update the database
      $ php /opt/mediawiki/maintenance/update.php
