Mediawiki

https://www.mediawiki.org/wiki/Manual:Running_MediaWiki_on_Debian_or_Ubuntu

Install the LAMP stack - Apache, MySQL etc

sudo apt-get install apache2 mysql-server php php-mysql libapache2-mod-php php-xml php-mbstring

and additional bits for mediawiki

sudo apt-get install php-apcu php-intl imagemagick inkscape php-gd php-cli php-curl php-bcmath git

Secure mysql

sudo mysqladmin -u root password <password>

sudo mysql_secure_installation

Set up noip

Will need to install 'make'

sudo apt install build-essential

Download the DUC and save the file to: /usr/local/src

Open terminal and execute the following:

cd /usr/local/src

tar xzf noip-duc-linux.tar.gz

cd noip-2.1.9-1

make

make install

If the install did not create configuration file then run. You need username/password for noip and port 80 need to be forwarded to the machine

/usr/local/bin/noip2 -C

To start at boot time, create a service by creating a file /lib/systemd/system/noip.service containing

[Unit]

Description=NOIP dynamic dns updater

After=multi-user.target

[Service]

Type=forking

ExecStart=/usr/local/bin/noip2 -c /usr/local/etc/no-ip2.conf

sudo systemctl enable noip.service

CREATE DATABASE bradnor;

USE bradnor;

CREATE USER 'mediawiki'@'localhost' IDENTIFIED BY '<password>';
