Setting up Apache2

sudo gedit /etc/apache2/sites-available/mediawiki.conf

<virtualhost *:80> <Directory/var/www/html> Options Indexes followsymlinks multiviews Allowo Verride all Require all granted </Directory> # the SERVERNAME Directive sets the request scheme, Hostna Me and port that # The server uses to identify itself. This was used when creating # redirection URLs.    In the context of the virtual hosts, the ServerName # specifies what hostname must appear in the request ' s Host:header to # match this virtual host.    The default virtual host (this file) of this # value is not decisive as it's used as a last resort host regardless.    # However, must set it for any further virtual host explicitly. #ServerName www.example.com ServerAdmin [email protected] documentroot/var/www/html # Available Loglevels:    Trace8, ..., Trace1, debug, info, notice, warn, # Error, Crit, alert, Emerg.    # It's also possible to configure the loglevel for particular # modules, e.g. #LogLevel INFO ssl:warn errorlog ${apache_log_dir}/error.log customlog ${apache_log_dir}/access.log Combined # for most CONF  iguration files from conf-available/, which was # enabled or disabled at a global level, it's possible to # include A line for only one particular virtual host. For example the # following line enables the CGI configuration for this host only # after it has been globally Disab    LED with "a2disconf". #Include conf-available/serve-cgi-bin.conf</virtualhost># vim:syntax=apache ts=4 sw=4 sts=4 SR Noet

sudo a2ensite mediawiki.confsudo a2dissite 000-default.confsudo apache2ctl configtestsudo systemctl restart apache2

Setting up the rewrite rules

sudo gedit /var/www/html/.htaccess

## http://www.mediawiki.org/wiki/Manual:Short_URL/Apache# Enable the rewrite engineRewriteEngine On# Short URL for wiki pagesRewriteRule ^/?wiki(/.*)?$ %{DOCUMENT_ROOT}/w/index.php [L]# Redirect / to Main PageRewriteRule ^/*$ %{DOCUMENT_ROOT}/w/index.php [L]

LocalSettings.php

sudo gedit /var/www/html/w/LocalSettings.php

## https://www.mediawiki.org/wiki/Manual:Short_URL$wgScriptPath = "/w";        // this should already have been configured this way$wgArticlePath = "/wiki/$1";$wgUsePathInfo = true;

Step 8-extension:syntaxhighlight

Troubleshooting

After updating to MediaWiki v1.26 and above, some users started reporting problems with the extension.

• Try pointing? $wgPygmentizePath ? In localsettings.php towards a external pygmentize binary.
• See The?phabricator Task?on this for further suggestions and information.

sudo apt install pythoncurl https://bootstrap.pypa.io/get-pip.py -o get-pip.pysudo python get-pip.pysudo pip install Pygmentswhich pygmentize

/usr/local/bin/pygmentize

sudo gedit /var/www/html/w/LocalSettings.php

$wgPygmentizePath = "/usr/local/bin/pygmentize";
