Installing Mediawiki 1.31.3 on OpenBSD 6.5

Introduction

We'll install a mediawiki that uses sqlite.

Prerequisites

Make sure you have a server, a domain (we'll use w2.mgk.ro). Make sure you have followed the OpenBSD Post Install Steps.

Install PHP

pkg_add -r php%7.3 php-gd%7.3 php-intl%7.3 php-pdo_sqlite%7.3 pecl73-imagick

Enable required PHP extensions by:

ln -sf /etc/php-7.3.sample/imagick.ini /etc/php-7.3/
ln -sf /etc/php-7.3.sample/gd.ini /etc/php-7.3/                       
ln -sf /etc/php-7.3.sample/intl.ini /etc/php-7.3/
ln -sf /etc/php-7.3.sample/opcache.ini /etc/php-7.3/
ln -sf /etc/php-7.3.sample/pdo_sqlite.ini /etc/php-7.3/ 

Configure files

Create site directories:

domain="w2.mgk.ro"
mkdir -p -m 775 /var/www/src /var/www/sites /var/www/sites/${domain} /var/www/sites/${domain}/{data,images}
mkdir /var/www/htdocs/${domain}
chown :staff /var/www/src /var/www/sites /var/www/sites/${domain}
chown :wheel /var/www/htdocs/${domain}
chown :www /var/www/sites/${domain}/{data,images}
chmod +t /var/www/sites/${domain}/images
chmod 775 /var/www/sites/w2.mgk.ro/mediawiki*  

Download mediawiki, with extensions and skins:

cd /var/www/src
ftp https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.3.tar.gz
ftp https://extdist.wmflabs.org/dist/extensions/MobileFrontend-REL1_31-289f540.tar.gz
ftp https://extdist.wmflabs.org/dist/skins/MinervaNeue-REL1_33-1903d1a.tar.gz

Extract mediawiki, extensions and skins:

tar -xzf mediawiki-1.31.3.tar.gz -C /var/www/sites/${domain}
tar -xzf MobileFrontend-REL1_31-289f540.tar.gz -C /var/www/sites/${domain}/mediawiki-1.31.3/extensions
tar -xzf MinervaNeue-REL1_33-1903d1a.tar.gz -C /var/www/sites/${domain}/mediawiki-1.31.3/skins

Create site links in htdocs:

ln -sf ../../sites/${domain}/mediawiki-1.31.3 /var/www/htdocs/${domain}/w

Enable services

rcctl enable php73_fpm
rcctl start php73_fpm
rcctl enable httpd
rcctl start httpd

Configure web server

Add aram to the www group:

usermod -G www aram

Create empty httpd.conf file and configure permissions:

touch /etc/httpd.conf
chown root:staff /etc/httpd.conf 
chmod 664 /etc/httpd.conf

Run the MediaWiki installer

Use this initial config:

server "w2.mgk.ro" {
	listen on * port 80
	root "/htdocs/w2.mgk.ro"
	directory no index

	location "/w/*.php" {
		fastcgi socket "/run/php-fpm.sock"
	}
	location "/w/mw-config/*.php" {
		fastcgi socket "/run/php-fpm.sock"
	}
	location "/w/" { directory index index.php }
	location "/w/mw-config/*" { directory index index.php }
	location "/w/mw-config/images/*" { pass }

	location "/w/resources/assets/*" { pass }
	location "/w/resources/lib/*" { pass }
	location "/w/resources/src/*" { pass }
	location "/w/skins/*" { pass }
	location "/w/extensions/*" { pass }

	location "/images/deleted/*" { block }
	location "/images/*" { pass }

	location "/" {
		block return 301 "http://$SERVER_NAME/w/mw-config"
	}
	location "/*" { block }
}

Enable and start PHP and httpd:

rcctl enable php73_fpm
rcctl start php73_fpm
rcctl enable httpd
rcctl start httpd

Visit http://w2.mgk.ro/ and run the installer. Use /sites/w2.mgk.ro/data for the SQLite data directory. Download LocalSettings.php and upload it to /var/www/htdocs/${domain}/w

scp LocalSettings.php w2.mgk.ro:/var/www/htdocs/w2.mgk.ro/w

The wiki should now work with traditional (long) URLs.

Enable short URLs

Use this httpd.conf to enable short URLs and disable access to the installer.

server "w2.mgk.ro" {
	listen on * port 80
	root "/htdocs/w2.mgk.ro"
	directory no index

	location "/w/*.php" {
		fastcgi socket "/run/php-fpm.sock"
	}
	location "/wiki/*" {
		fastcgi param SCRIPT_FILENAME "/htdocs/w2.mgk.ro/w/index.php"
		fastcgi socket "/run/php-fpm.sock"
	}
	location "/w/" { directory index index.php }

	location "/w/resources/assets/*" { pass }
	location "/w/resources/lib/*" { pass }
	location "/w/resources/src/*" { pass }
	location "/w/skins/*" { pass }
	location "/w/extensions/*" { pass }

	location "/images/deleted/*" { block }
	location "/images/*" { pass }

	location "/" {
		block return 301 "http://$SERVER_NAME/wiki/Main_Page"
	}
	location "/*" { block }
}

Then edit LocalSettings.php to enable short URLs:

$wgScriptPath = "/w";
$wgScriptExtension = ".php";
$wgArticlePath = "/wiki/$1";
$wgUsePathInfo = true;

Restart httpd:

doas rcctl restart httpd  

You are now done.

Enable mobile support

Edit LocalSettings.php to enable it (append it at the bottom):

wfLoadExtension( 'MobileFrontend' );
$wgMFAutodetectMobileView = true;
$wgMFDefaultSkinClass = 'SkinVector';
