Mediawiki 1.23.0 is the first stable release of the new MediaWiki 1.23 release series. This is a Long Term Support release (LTS) and will be supported until May 2017.

# apt-get install apache2 mysql-server php5 php5-common libapache2-mod-php5 php5-cli php5-mysql php5-curl php5-gd php-apc php5-intl
If using SSL on Apache:

These are needed for email messages (password reset etc):

Installation
Download the Mediawiki 1.23.0 package and extract it:
# wget http://download.wikimedia.org/mediawiki/1.23/mediawiki-1.23.0.tar.gz # tar xvfz ./mediawiki-1.23.0.tar.gz
Change the name as you need:
# mv ./mediawiki-1.23.0 ./wiki
Stop the webserver (Apache2 in our case):
# service apache2 stop
Backup the database (!):
# mysqldump -uroot -p wiki_db >/root/wiki_backup.sql
Configuration
Rename the current Mediawiki folder to wiki-1.21.10:
# mv /var/www/wiki /var/www/wiki-1.21.10
Move the new Mediawiki v1.23 folder to the webserver’s root /var/www/:
# mv ./wiki/ /var/www/
Change to webserver’s root directory:
# cd /var/www/
Copy files:
# cp ./wiki-1.21.10/LocalSettings.php ./wiki/ # cp ./wiki-1.21.10/logo.png ./wiki/ # cp ./wiki-1.21.10/favicon.ico ./wiki/
Copy extensions and images (assuming you have checked the compatibility of any installed extensions):
# cp -R ./wiki-1.21.10/extensions/ ./wiki/ # cp -R ./wiki-1.21.10/images/ ./wiki/
Make the LocalSettings.php configuration file readable by the webserver:
# chown -R root:root ./wiki/ # chown root:www-data ./wiki/LocalSettings.php
Make the cache directory writeable by the webserver group:
# chown root:www-data ./wiki/cache # chmod 0775 ./wiki/cache
Perform the database upgrade. This will insert missing tables, update existing tables, and move data around as needed:
# php5 ./wiki/maintenance/update.php --quick
Start the webserver:
# service apache2 start
