Sorry! :/ thanks for spotting!

Pasting db setup here to make it easier to find:

sudo apt-get install mariadb-server
sudo sed -i -e 's/bind-address/#bind-address/g' /etc/mysql/my.cnf
sudo service mysql restart

Two remarks, from when I used this script to install the new wikidata-constraints wiki on labs (woo!):

  1. On line 12, mysql-client was not installed because it conflicted with mariadb-server-10.0. I first tried removing mariadb-server because I didn’t know what it was, which was a stupid solution; the correct solution, I think, is to remove mysql-client from the package list. mariadb-client-core-10.0, which is pulled in by mariadb-server, provides a /usr/bin/mysql, but apparently does not provide a mysql-client package that apt is aware of.
  2. I had to change $wgScriptPath from "/wiki" to "" in LocalSettings.php, since line 23 clones MediaWiki directly into the Apache DocumentRoot, not into wiki/. ("/" as $wgScriptPath does not work, by the way.)

Apart from those minor issues, this worked pretty well, so thanks for putting this document together!

One more small goodie for LocalSettings.php:

$wgUsePrivateIPs = true;
$wgSquidServers = [ 'IP HERE' ];

Without that, all anonymous edits will be credited to the proxy’s IP (not sure if that’s public, so I replaced it with IP HERE above).
