Here are some quick instructions on how to download and install PmWiki 2.0. Improvements to these instructions would be greatly appreciated. Note that PmWiki 2.0's installation procedure has not been tested on as many platforms as PmWiki 1.0, so there may be some glitches still. (Just report any problems you encounter to the pmwiki-users mailing list? or the PmWiki Issue Tracking System.)
1. Download the latest version of PmWiki from http://www.pmwiki.org/pub/pmwiki-devel/.
2. Extract the tar image using "tar zxvf pmwiki-''version''.tgz" (note that the tar file has to be extracted with the proper permissions set... see the note at the end of this page for more.). This will create a pmwiki-x.y.z directory which contains the PmWiki software. Rename this directory to "pmwiki" by executing "mv pmwiki-x.y.z pmwiki" . The files in this directory include:
COPYING The GNU General Public License
local/ A directory for local configuration scripts
pmwiki.php Main PmWiki script
pub/ Directory of publicly accessible files
css/ Directory for generic .css files
skins/ Directory of layout templates?
sample-config.php A sample configuration file
scripts/ Some scripts that extend the possibilities of PmWiki
wikilib.d/ Directory containing some default PmWiki files
These files need to be placed where they can be accessed by a web server (e.g. in a public_html directory of some sort).
3. Open a web browser to the pmwiki.php script. PmWiki will then attempt to create the wiki.d directory for holding wiki pages with the appropriate ownerships and permissions. This step will likely fail, but if it works then you can proceed to step 4 below.
chmod 2777 ." (note the dot at the end). This will (1) make the directory writable so the web server can create the data directory it needs for the wiki files, and (2) preserve group ownership of the directory so the installer account can manipulate the files created in this directory.
4. If you're running Apache version 2.0.30 or later, you may need to set the AcceptPathInfo directive to "on" for the pmwiki.php script. This can be as simple as adding
AcceptPathInfo on
to either the .htaccess file in the directory containing pmwiki.php or the server's httpd.conf file. If changing the httpd.conf file, don't forget to restart Apache to have the change take effect.
For more on this issue, see AcceptPathInfo?.
5. Check out InitialSetupTasks for other tasks you may want to perform to begin customizing your PmWiki installation. You might also want to peruse the ReleaseNotes for further information.
(Note: It is important that the tar file (*.tar) is unpacked with the proper permissions set. For *nix operating systems, please check your permission mask by typing umask at the command-line. If it says anything other than "2", you'll need to change the permission mask by typing umask 002 at the command-line. Then unpack the tar file. If you do not do this the pmwiki.php script will not be able to make use of other files in the tree.)
