Installing Kallithea on Clear Linux Latest

Kallithea is a free and open-source software for managing Git, Mercurial, and Subversion repositories. This tutorial will guide you through the installation of Kallithea on Clear Linux Latest.

Prerequisites

Before starting the installation process, ensure that:

You have a clear Linux installation running. You can download the latest Clear Linux ISO image from their official website.
You have root access to your system.
You have an active internet connection.

Step 1: Update the system

It is always good to start with updating the system. Open the terminal and run the following command:

sudo swupd update

This command will update the system to the latest version.

Step 2: Install PostgreSQL

Kallithea requires a PostgreSQL database to store its data. To install PostgreSQL on Clear Linux, run the following command in the terminal:

sudo swupd bundle-add postgresql

After the installation is complete, start the PostgreSQL server by running the following command:

sudo systemctl start postgresql

Step 3: Install Kallithea

Once PostgreSQL is installed and running, it's time to install Kallithea. To do that, run the following command in the terminal:

sudo swupd bundle-add kallithea

This will install Kallithea and all its dependencies.

Note: If you want to install Kallithea without Mercurial, use the following command instead:

sudo swupd bundle-add kallithea-hgless

Step 4: Configure Kallithea

After installing Kallithea, you need to configure it to work with PostgreSQL.

First, create a new PostgreSQL user for Kallithea using the following command:
```
sudo su - postgres -c 'createuser -P kallithea'
```
This will prompt you to set a password for the new user. Choose a secure password and remember it.
Once the user is created, create a new PostgreSQL database for Kallithea using the following command:
```
sudo su - postgres -c 'createdb -O kallithea kallithea_db'
```
The next step is to configure Kallithea to use the PostgreSQL database. Open the Kallithea configuration file /etc/kallithea/kallithea.ini using your favorite text editor:
```
sudo nano /etc/kallithea/kallithea.ini
```
Look for the [server:main] section in the configuration file and add the following lines to it:
```
[server:main]
database = postgresql://kallithea:<password>@localhost/kallithea_db
```
Note: Replace <password> with the password you set for the kallithea PostgreSQL user in the previous step.
Save and close the configuration file.

Step 5: Start Kallithea

After configuring Kallithea, start the Kallithea service by running the following command in the terminal:

sudo systemctl start kallithea

You can now access Kallithea by opening a web browser and entering the Clear Linux IP address followed by port 5000 (default Kallithea port) in the address bar:

http://<Clear_Linux_IP>:5000

You should now see the Kallithea login page. You can login as an administrator using the default credentials:

Username: admin
Password: admin
