How to Install Kallithea on OpenSUSE Latest

Kallithea is an open-source source code management software that provides a web interface for managing Git, Mercurial, and Subversion repositories. It is a great option for those who prefer a self-hosted solution for source code management. Here, we will guide you through the installation of Kallithea on the latest version of OpenSUSE.

Prerequisites

Before we proceed with the installation of Kallithea, ensure that you have the following prerequisites:

• A user account with sudo privileges
• OpenSUSE installed and up-to-date
• Python 2.7 or later and Python development files installed
• Git or Mercurial installed
• Apache or Nginx web server installed and running

Once you have taken care of these prerequisites, follow the steps below to install Kallithea:

Step 1: Install Required Packages

First, we need to ensure that all required packages are installed on our system. Use the following command to install the necessary packages:

$ sudo zypper in python-pip python-virtualenv

This command will install pip, a package management system used to install and manage Python packages, and virtualenv, a tool used to create isolated Python environments.

Step 2: Create a Virtual Environment and Install Kallithea

Next, we need to create a virtual environment for Kallithea and install it. Use the following commands to create a virtual environment and install Kallithea:

$ mkdir ~/kallithea
$ cd ~/kallithea
$ virtualenv kenv
$ source kenv/bin/activate
$ pip install kallithea

These commands create a directory called "kallithea" in the home directory and create a virtual environment called "kenv" inside the directory. Once the virtual environment is activated, we install Kallithea using pip.

Step 3: Configure Kallithea

After the installation, we need to configure Kallithea. Firstly, we need to create a configuration file. Use the following command to create a configuration file:

$ kallithea-cli config-create /etc/kallithea/kallithea.ini

This will create a configuration file in the "/etc/kallithea/kallithea.ini" directory.

Next, we need to edit the configuration file to suit our needs. We can use any text editor to edit the file. For example, to use vim, use the following command:

$ sudo vim /etc/kallithea/kallithea.ini

In this file, we can set the database details, secret key, email settings, and other options. Once we have finished editing the file, we need to save and close it.

Step 4: Set up Apache or Nginx

To access Kallithea in a web browser, we need to set up Apache or Nginx. Here, we will show you how to set up Apache.

Open the default Apache configuration file using the following command:

$ sudo vim /etc/apache2/httpd.conf

Add the following lines at the end of the file:

WSGIScriptAlias /kallithea /srv/www/kallithea/kallithea.wsgi
<Directory /srv/www/kallithea>
        WSGIProcessGroup kallithea
        WSGIApplicationGroup %{GLOBAL}
        Order deny,allow
        Allow from all
</Directory>

Save and close the file.

Next, create a file called "kallithea.wsgi" inside the "/srv/www/kallithea/" directory and add the following lines to it:

import sys
sys.path.insert(0, '/home/<YourUserName>/kallithea/kenv/lib/python<version>/site-packages')
from kallithea.webhooks import wsgi_app as application

Replace "" with your username and "" with the version of Python you installed. Save and close the file.

Finally, restart the Apache server using the following command:

$ sudo systemctl restart apache2

You should now be able to access Kallithea in a web browser, using the URL http://localhost/kallithea.
