====== DokuWiki on openSUSE ======

First, it is quite simple to install DokuWiki on openSUSE (or SLES/SLED). Download the tarball from http://download.dokuwiki.org and unpack it into ''/srv/www/htdocs''. Then rename the folder you created by unpacking to ''dokuwiki'' and that's nearly all. When you do it on your own PC, you can invoke DokuWiki by entering ''http://localhost/dokuwiki/install.php'' (or replace ''localhost'' by the name of the host you installed it on) as URL in your browser. The invoked ''install.php'' will tell you what is wrong, for example the data dir is not writeable by the web server and so on.

Second, to do all this manually is annoying. So I decided to use openSUSE's build service (see http://en.opensuse.org/Build_Service for details) and put DokuWiki into an rpm package that can be installed on all available openSUSE and SLE versions. When you want to install it from there, you may add ''http://download.opensuse.org/repositories/home:/werfl/<your openSUSE version>'' as installation repository. Unfortunately, it needs apache to run, since this is the only httpd I use myself and where I know how to write the needed config file...

===== What did I do to create this rpm package? =====

First, I had to put the DokuWiki files where they belong according to openSUSE's policy (''/srv/www/dokuwiki''). Then, I had to add an apache configuration file that defines an alias ''/dokuwiki'' for this place and contains all the lines from the ''.htaccess'' files in the tarball. Downloading, creating the config, and repacking for creation of the rpm is all done by a shell script.

On **2012-11-16** I edited the script so that the config files are now in ''/etc/DokuWiki'', and the ''conf'' directory inside the DokuWiki source tree is a symbolic link to the new location.

On **2015-07-02** I edited the script again so that the scripts now stay with "/usr/bin/php" instead of my modification "/usr/bin/php5". Plus the generated Apache config file contains code for Apache 2.2 and 2.4 now.

Well, that's about all. With a fast internet connection, the script runs in less that a minute for me :-). The resulting file is used by the build process as well as the following ''spec'' file:

%description
DokuWiki is a standards compliant, simple to use Wiki, mainly aimed at creating
documentation of any kind. It is targeted at developer teams, workgroups and small
companies. It has a simple but powerful syntax which makes sure the datafiles
remain readable outside the Wiki and eases the creation of structured texts.
All data is stored in plain text files - no database is required.

Read the DokuWiki Manual to unleash the full power of DokuWiki.

You can use the ''spec'' file and the tarball that is produced by the shell script to build DokuWiki locally. Just save the ''spec'' file as ''/usr/src/packages/SPECS/DokuWiki.spec'', put the tarball into ''/usr/src/packages/SOURCES/'' and start ''rpmbuild -ba /usr/src/packages/SPECS/DokuWiki.spec''. The resulting rpm will appear in ''/usr/src/packages/RPMS/noarch/'' (plus a source rpm in ''/usr/src/packages/SRPMS/'').
