Manual:Running MediaWiki on Gentoo Linux

= Prerequisites = It is possible to have connection problems when you emerge something.

Try to add one line for mirror list into your /etc/make.conf like following: GENTOO_MIRRORS="ftp://ftp.heanet.ie/pub/gentoo/ http://ftp.easynet.nl/mirror/gentoo/"

You can get possible mirros and test them by accessing http://www.gentoo.org/main/en/mirrors.xml

emerge sync emerge ufed -uD Note: ufed is the Gentoo Linux USE flags editor ufed (check useflags, you'll need mod_php, plus gd if you want thumbnails) the option -uD means update and check the dependence tree thoroughly.
 * Optional, suggested


 * Needed for support of mathematical formulas

emerge imagemagick (ImageMagick can also make thumbnails if you do not want to include gd [a library] support in php). If you have done this it is a good ideea to add suport for imagemagick in the USE flags.

To add LaTeX support do: emerge tetex After that you should see the programs latex and dvips available on the command line.

Finally do: emerge dev-lang/ocaml

You can find additional info here about installing support for mathematical formulas in mediwiki.

Remember to -p them first! if you already have them, you probably don't need them again!. For example type 'emerge -p mysql' to see what would happen emerge mysql -uD emerge apache -uD USE="session" emerge php -uD Note: I encountered a problem when merge php,  ERROR: media-video/nvidia-kernel-1.0.5336-r4 failed. I checked it out from http://forums.gentoo.org/ and found it is not a simple problem. I suggest to use 'USE="session" emerge php ' instead of 'USE="session" emerge php -uD'
 * Required packages...

(check useflags with ufed. php has many use flags options.. use emerge -pv php to see them all.) NOTE!! by default, some (if not all) php ebuilds disable sessions, which will break logins. add sessions by appending 'session' to the mod_php USE line in /etc/portage/package.use) (probably required) (so try the following) USE="session" emerge mod_php -uD

Another NOTE: you can also add 'session' in the USE flags permenently with ufed. I have not encountered yet problems with this setting. Also make sure that mysql suport in added in USE when emerging php (stating the obvious but it doesn't hurt :))

Configure Apache
start web server by apache2 Stop it by apache2ctl stop

(get services going by default) rc-update add apache2 default

(turn on services) /etc/init.d/apache2 start

Add PHP Support
apache2 uses modules to dynamically load and unload extra functionalities. php support is one of them. There is no mod_php module in apache server after the default installation. We need to add mod_php into apache. Edit the configuration file of apache2

easy way to add php support
vi /etc/conf.d/apache2 APACHE2_OPTS="-D SSL -D PHP4" /etc/init.d/apache2 restart
 * 1) APACHE2_OPTS="-D SSL"

complex way to do things
vi /etc/apache2/conf/apache2.conf You will see module list in apache2.conf LoadModule access_module                modules/mod_access.so LoadModule auth_module                   modules/mod_auth.so LoadModule auth_anon_module              modules/mod_auth_anon.so LoadModule auth_dbm_module               modules/mod_auth_dbm.so

Add mod_php into it by one more line: LoadModule php4_module   extramodules/libphp4.so Consequently add .php file name handling capability by adding AddType application/x-httpd-php .php AddType application/x-httpd-php .phtml AddType application/x-httpd-php .php3 AddType application/x-httpd-php .php4 AddType application/x-httpd-php-source .phps save apache2.conf and restart apache server apache2ctl restart or /etc/init.d/apache2 restart We now have an apache server with php support.

Configure MySQL
Refer to http://meta.wikimedia.org/wiki/MySQL_config for details

Intialize the mysql database ebuild /var/db/pkg/dev-db/mysql-VERSION/mysql-VERSION.ebuild config Start the server /etc/init.d/mysql start Choose a password: /usr/bin/mysqladmin -u root password 'PASSWORD' Test it mysqlshow -p

Let it run automatically each time your machine is powered up rc-update add mysql default

= Get Mediawiki = Run the following command to install mediawiki:

emerge mediawiki

Unpack
using tar -xvvzf filename (don't put it into your webroot, alias the directory, conditional to php being operational) cp it into /var/www/localhost if you like, where the default www root(htdocs) is located.

Set Permissions
user should be apache, group should be apache. You should not give anybody access to this directory.. or at least LocalSettings.conf as it contains passwords! Just let user apache do it.

Mediawiki 1.3.2 needs to write confi directory during initialization. cd /var/www/localhost/mediawiki chmod a+w config

Alias Directory
edit your /etc/apache2/conf ... commonapache2.conf? file apache configuration

You do NOT want mediawiki in a world readable directory, when php isn't running, so this is usefull: (this is using apache2, so the php4 module is called sapi_apache2.c )    Alias /mediawiki/ /var/www/localhost/mediawiki-1.3.3/ Alias /mediawiki /var/www/localhost/mediawiki-1.3.3 Alias /wiki_persistant/ /var/www/localhost/wiki_persistant/ Alias /wiki_persistant /var/www/localhost/wiki_persistant

 Order deny,allow Allow from all 

 Options +includes Order deny,allow Allow from all  
 * 1)       AllowOverride All

Setup Rewrite Rules
I have no idea how to do these, see Rewrite Rules

Restart apache
/etc/init.d/apache2 restart

= Run the Configuration Web Page = yes, you have to config that directory manually...

= MediaWikis running on Gentoo =
 * http://gentoo-wiki.com A little surprise for me when I found it. :-)
 * http://escargot.icehouse.net/mediawiki  (the page upgrade from 1.2 to 1.3 was origionally written with a gentoo box)  and this user is silly enough to be willing to provide _limited_ tech support if you bother to User:AaronPeterson (he prefers telephone, because he types too much!)
