====== MediaWiki VPS Install ======

<note>
--- //John Pumford-Green 27/04/23 06:21//

I have recenlty rebuilt the VPS install during a hardware upgrade, 
and the ''Mediawiki'' install is no longer in place.

The following guide would allow it to be re-installed should I decide 
to.

</note>

To compare ''mediawiki'' with ''dokuwiki'' I installed ''mediawiki'' 
on my little shack server. 

I followed the instructions here

[[https://www.mediawiki.org/wiki/Manual:Running_MediaWiki_on_Debian_or
_Ubuntu]]

and did a few tweaks etc. to get things running.

I forgot to document the tweaks!

So I thought there would be no harm in installing it on my VPS to run 
alongside the main ''dokuwiki'' site, with a view to deciding whether 
to switch to ''mediawiki'' later.

Here are my steps to install mediawiki on the VPS machine, which 
already has a fully configured and working webserver & PHP. The main 
addition will be setting up a SQL server (probably MariaDB).

==== Installing pre-requisites ====

<code bash>sudo apt-get install apache2 mariadb-server php php-mysql 
libapache2-mod-php php-xml php-mbstring</code>

<code bash>wget 
https://releases.wikimedia.org/mediawiki/1.38/mediawiki-1.38.1.tar.gz<
/code>

<code bash>tar zxvf mediawiki-1.38.1.tar.gz</code>

<code bash>sudo mkdir /var/www/html/mediawiki</code>

<code bash>sudo mv mediawiki-1.38.1/* /var/www/html/mediawiki</code>

That has installed a SQL server and the ''mediawiki'' files into the 
webserver root. Next is to configure the SQL database to hold the 
wiki.

==== SQL Configuration ====

<code sql>
gm4slv@gm4slv:~$ sudo service mysql start
gm4slv@gm4slv:~$ sudo mysql -u root -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 36
Server version: 10.3.34-MariaDB-0+deb10u1 Debian 10

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input 
statement.

MariaDB [(none)]> CREATE USER 'new_mysql_user'@'localhost' IDENTIFIED 
BY 'mwPass';
Query OK, 0 rows affected (0.018 sec)

MariaDB [(none)]> quit;
Bye

</code>

=== Create the database and grant the user access ===

<code sql>
gm4slv@gm4slv:~$ sudo mysql -u root -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 37
Server version: 10.3.34-MariaDB-0+deb10u1 Debian 10

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input 
statement.

MariaDB [(none)]> CREATE DATABASE my_wiki;
Query OK, 1 row affected (0.003 sec)

MariaDB [(none)]> use my_wiki;
Database changed
MariaDB [my_wiki]> GRANT ALL ON my_wiki.* TO 
'new_mysql_user'@'localhost';
Query OK, 0 rows affected (0.001 sec)

MariaDB [my_wiki]> quit;
Bye
</code>

Browse to [[https://gm4slv.org.uk/mediawiki]] and got an error 
message that there was a PHP component missing ''intl''


<code bash>
sudo apt-get install php-intl
</code>

<code bash>
sudo service apache2 restart
</code>

Browse to ''mediawiki'' again and all seems well. The message now is 
that LocalSettings.php is missing, which is created at the next step, 
following the on screen link.

{{:public:computers:screenshot_2022-06-29_15.43.11.png?direct&400|}}

Configure the SQL access: 

<code>
Database Username : new_mysql_user
Database Password : mwPass
</code>

Complete the questions, select the required extensions etc. and 
download the ''LocalSettings.php'' file. Then upload the file to the 
VPS and put it in ''/var/www/html/mediawiki''

==== Tweaks ====

=== File uploads ===

Make sure ''images'' directory has ''ugo+rwx'' permissions

=== Logo ===


Somehow upload a ''logo.png'' into ''images'' and edit 
''LocalSetting.php'' to point at the log:

<code php>
$wgLogos = [
        '1x' => "$wgResourceBasePath/images/logo.png",


        'icon' => "$wgResourceBasePath/images/logo.png",
];
</code>


=== Image thumbnails & pdf ===

''to be continued''


<code bash>sudo apt install ghostscript imagemagick xpdf-utils </code>

add to LocalSettings.php:

<code php>
$wgPdfProcessor = '/usr/bin/gs';
$wgPdfPostProcessor = $wgImageMagickConvertCommand; // if defined via 
ImageMagick
// $wgPdfPostProcessor = '/usr/bin/convert';  // if not defined via 
ImageMagick
$wgPdfInfo = '/usr/bin/pdfinfo';
$wgPdftoText = '/usr/bin/pdftotext';


$wgFileExtensions[] = 'pdf';

</code>

Now upload a ''pdf'' file and  it should appear in the file brower.

Try putting it in a page with the <gallery> funtion

<code html>

<gallery>
File:Blog.pdf|page=1
</gallery>

</code>
