This page covers all steps to manually install and configure MediaWiki.
MediaWiki can be difficult to install if you do not have any experience with Apache (web server software), PHP and MySQL/MariaDB (database). The Appendices section below offers easier alternatives to manual installation.
The Appendices section below also provides installation notes for specific system configurations.
Check the installation requirements
Check that your system meets the installation requirements.
Make sure to also check the Release notes of the MediaWiki version that you plan to install.
Download the MediaWiki software
Download the MediaWiki tar file from the official download page.
Generally, if you're using a production environment, you want to be running the latest stable release, which is MediaWiki 1.39.0.
Extract the MediaWiki software
The downloaded file is in
.zip or in
.tar.gz file format.
You need to uncompress this archive file before use.
You can uncompress the file locally (and then upload via FTP to the server) or directly on your server.
On Linux and Mac OS X, you can uncompress the file using the command:
tar -xf mediawiki-*.tar.gz
chown -R <new_owner_user> <mediawiki_folder>
Upload files to your web server
If you have not already uploaded the files to your web server (or copied, if your web server software runs locally on your
localhost), do so now.
Upload the files to your web server's web directory either by:
- directly copying the unzipped folder or
- by using an FTP client such as FileZilla (Windows, OSX and Linux) or Cyberduck (Windows and OSX).
- by using software already provided by your hosting service, such as the cPanel File Manager
If your upload tool has a "change file names to lowercase" option, then you must disable this.
If you use the Apache HTTPD web server, the correct directory is specified in your
httpd.conf file in the
By default, this is
The exact location of the Apache server settings and directories file
httpd.conf depends on your operating system.
In Debian and Ubuntu, the file for Apache server settings and directories is
In Red Hat and Fedora, the file is
Rename the uploaded folder to whatever you would like to have in the URL.
If your web server is running as
http://localhost for example, renaming to
/w/ directory would mean you would access your wiki at
Set up the database
MediaWiki's installation script will ask you for a database name and database username, so MediaWiki can store the content of the wiki.
If you already have a database server and know the password for the "root" (admin) user, skip to the #Run the installation script section below.
If you don't know the password for the root user, for example if you are on a hosted server, you will have to create a new database before you run the MediaWiki installation script in the next section.
SQLite, MariaDB/MySQL, and PostgreSQL are supported databases. If you're unsure which database to choose, use MariaDB.
After finishing the database setup, continue with #Run the installation script below.
No further setup is required for SQLite if the
pdo-sqlite module for PHP is installed on the system.
On the SQLite installation page, choose a database name (which can be anything) and the SQLite database directory. For the database directory, the installer will attempt to use a subdirectory outside of the document root and create it if needed. If this directory is not safe (for example, web-readable), change it manually to avoid making it accessible to everyone on the web.
- Use a control panel software offered by your Hosting service (example: PhpMyAdmin)
- Use ssh to log into your host and type the commands below into a MySQL prompt. See the corresponding documentation of your hosting provider. Alternatively, contact your hosting provider to have them create an account for you.
The following commands create a database named
my_wiki, a user named
wikiuser, and set permissions for the user on that database.
CREATE DATABASE my_wiki; CREATE USER 'wikiuser'@'localhost' IDENTIFIED BY 'database_password'; GRANT ALL PRIVILEGES ON my_wiki.* TO 'wikiuser'@'localhost' WITH GRANT OPTION;
Only if your database is not running on the same server as your web server, you need to give the appropriate web server hostname (
mediawiki.example.com in the example below):
GRANT ALL PRIVILEGES ON my_wiki.* TO 'wikiuser'@'mediawiki.example.com' IDENTIFIED BY 'database_password';
If you are using PostgreSQL, you will need to either have a database and user created for you, or supply the name of a PostgreSQL user with "superuser" privileges to the configuration form.
Often, this is the database user named
The following commands on a Linux command-line, as the postgres user, create a database user named
wikiuser, and a database named
my_wiki owned by the user named
createuser -S -D -R -P -E wikiuser (then enter the database password) createdb -O wikiuser my_wiki
or as superuser (default postgres) execute the following commands at the database prompt:
CREATE USER wikiuser WITH NOCREATEDB NOCREATEROLE NOSUPERUSER ENCRYPTED PASSWORD 'database_password'; CREATE DATABASE my_wiki WITH OWNER wikiuser;
Beware of the list of known issues when running MediaWiki with PostgreSQL.
Run the installation script
Next, complete the installation of MediaWiki by going to the URL of your MediaWiki installation in your web browser: Follow the instructions in Manual:Config script.
Keep up to date!
Once installed, make sure you stay up to date with releases, and keep your server secure!
Alternatives to manual installation
Instead of manually installing MediaWiki, alternative options might be easier:
- Hosting services which provide automatical installation of applications such as MediaWiki may offer outdated versions or have other issues. If you encounter problems, it does not mean that you cannot install MediaWiki. It means that you should install MediaWiki manually.
See also the comparison of distribution options.
The pages listed on Manual:OS specific help give more detailed installation instructions aimed at specific systems.
However, by and large these per-system docs are less maintained and might not always be up to date. First consult Installing MediaWiki (this page) before looking at per-system installation documentation.
