Installing PmWiki on Arch Linux

In this tutorial, we will guide you through the process of installing PmWiki on Arch Linux. PmWiki is a flexible and lightweight wiki system designed to be easy to install and customize.

Prerequisites

Before we begin, make sure you have the following requirements:

  • An Arch Linux installation with root privileges
  • A web server installed and configured (Apache or Nginx)
  • PHP installed and configured

Step 1: Download PmWiki

First, let's download the latest stable release of PmWiki from their official website using the following command:

$ wget https://www.pmwiki.org/pub/pmwiki/pmwiki-latest.tgz

Step 2: Extract the Archive

Next, extract the downloaded archive using the following command:

$ tar -xzf pmwiki-latest.tgz

This will create a pmwiki-x.y.z directory containing all the necessary PmWiki files.

Step 3: Install PmWiki

The next step is to install PmWiki into your web server's document root. You can do this by copying the contents of the pmwiki-x.y.z directory to your web server's document root.

$ cp -R pmwiki-x.y.z/ /var/www/html/pmwiki

Step 4: Set Permissions

In order for PmWiki to be able to save data, we need to set the correct file permissions. Change the ownership of the pmwiki directory to the web server user and group.

$ chown -R http:http /var/www/html/pmwiki

You may also need to adjust the permissions to allow PmWiki to write to certain directories. In general, it is recommended to set the uploads/ directory to be writable by the web server:

$ chmod -R 775 /var/www/html/pmwiki/uploads/

Step 5: Configure PmWiki

Next, we need to configure PmWiki by editing the pmwiki.php configuration file. Change to the pmwiki directory and copy the sample configuration file to pmwiki.php.

$ cd /var/www/html/pmwiki
$ cp pmwiki.php.sample pmwiki.php

Now edit pmwiki.php and adjust the configuration settings as needed. Some key settings to configure are:

  • $WikiTitle - The title of your wiki
  • $DefaultGroup and $DefaultName - The default group and page of your wiki
  • $EnableUpload - Whether to allow file uploads
  • $DefaultPasswords['admin'] - The password for the admin account

You can find more information about configuring PmWiki in the official documentation.

Step 6: Access PmWiki

Finally, you can access PmWiki by visiting the URL http://your-server/pmwiki/. You should see the PmWiki installation screen.

Follow the prompts to complete the installation process. Once installed, you can start editing pages and customizing your wiki.

Conclusion

In this tutorial, we have shown you how to install PmWiki on Arch Linux. By following these instructions, you should now have a working PmWiki installation on your Arch Linux system.
