- First version: https://wiki.heatsynclabs.org/wiki/MediaWiki_On_Lightsail
- See Also: MediaWiki_On_Lightsail, a copy of HSL install.
- I feel like I got really far with this, even building in automated backup to S3, but I can't find the documentation.

MediaWiki Supporting Software
First, the basics. You'll need all of these:
$ sudo apt install mariadb-server php php-mysql libapache2-mod-php php-xml php-mbstring
Next, the enhancements. These will give MediaWiki extra capabilities. See Optional Packages
$ sudo apt install php-apcu php-intl imagemagick php-cli php-curl git
Configure PHP
There are a couple settings that are worth checking in PHP:
$ cd /etc/php/7.3/apache2/ $ grep memory_limit php.ini $ grep upload_max_filesize php.ini
128 megs should be fine for memory.
I'm torn on filesize. I'm trying to fit on a $5/mo machine with a 40 Gig HDD. Most things other than video for use on the web can be under 2 megs (the default size). I feel like the best answer may be a plugin to store large files in S3 at 1/4th the price. It's not a one-way-door, though. I'm leaving mine at 2 megs for now.
Make sure the PHP plugins are enabled:
$ sudo phpenmod apcu $ sudo phpenmod curl $ sudo phpenmod intl $ sudo phpenmod mbstring $ sudo phpenmod xml $ sudo systemctl restart apache2
Configure MariaDB
It's time to stop generically referring to MariaDB as MySQL. MySQL is a once-great project that is no longer trustworthy. MariaDB is the leading Open Source RDBMS.
If you haven't done anything with it yet, there will be no password.
$ sudo mariadb -u root
Pick a username for MediaWiki to use (I'm using wiki_wiki as an example).
Pick a database name (I'm using hsl_wiki as an example).
Pick a password other than "CHANGE THIS PASSWORD".
MariaDB> create database deadmandao_wiki; MariaDB> grant all on deadmandao_wiki.* to 'wiki_wiki'@'localhost' identified by 'CHANGE THIS PASSWORD'; MariaDB> flush privileges;
Then you can verify it worked if you like. (there won't be any tables, but it shouldn't give you an auth error)
$ mariadb -u wiki_wiki -p MariaDB> show tables in deadmandao_wiki; MariaDB> exit
