How to Install Tracim on Arch Linux

Tracim is an open-source web-based application for collaborative document editing and management. It is developed and maintained by the Tracim team and is available for free on Github. In this guide, we will walk you through the steps to install Tracim on Arch Linux.

Prerequisites

Before proceeding with the installation, you should ensure that:

You have a user account with sudo privileges.
You have installed the latest version of Python in your system.
You have installed a web server and a database server.

Step 1: Install Required Dependencies

The first step is to install dependencies that are required by Tracim. Open terminal and run the following command:

sudo pacman -S python python-pip python-virtualenv python-wheel python-setuptools python-psycopg2 rabbitmq redis

Step 2: Create a Virtual Environment

Next, we will create a virtual environment for the Tracim application. A virtual environment is an isolated environment that has its own version of Python packages installed. This step will help to ensure that Tracim works optimally and does not interfere with other Python applications installed on the system.

To create a virtual environment, follow these steps:

Run the following command to create a directory for the virtual environment:
```
mkdir ~/tracim && cd ~/tracim
```
Create a virtual environment using Python virtualenv:
```
virtualenv -p /usr/bin/python3 venv
```
Activate the virtual environment using the following command:
```
source venv/bin/activate
```

Step 3: Install Tracim

To install Tracim, follow the steps below:

Clone the Tracim repository:

git clone https://github.com/tracim/tracim.git

Change directory to the cloned Tracim directory:
```
cd tracim/
```
Install required packages using the following command:
```
pip install -r requirements.txt
```

Step 4: Configure RabbitMQ and Redis

Tracim requires RabbitMQ and Redis to function properly. To configure these services, follow the steps below:

Create a new user for RabbitMQ:

sudo rabbitmqctl add_user tracim_user tracim_password

Set permissions for the Tracim user:

sudo rabbitmqctl set_permissions -p / tracim_user ".*" ".*" ".*"

Start the RabbitMQ server:
```
sudo systemctl start rabbitmq
```
Enable RabbitMQ to start on system boot:
```
sudo systemctl enable rabbitmq
```
Start the Redis server:
```
sudo systemctl start redis
```
Enable Redis to start on system boot:
```
sudo systemctl enable redis
```

Step 5: Configure Tracim

To configure Tracim, follow these steps:

Copy the example configuration file:

cp settings/tracim_cfg.example.yml settings/tracim_cfg.yml

Edit the configuration file to input database credentials:
```
vim settings/tracim_cfg.yml
```

Configure the database by running the following commands:

python manage.py db init
python manage.py db migrate
python manage.py db upgrade

Step 6: Run Tracim

To start the Tracim application, follow these steps:

Start a Celery worker for Tracim:
```
celery -A tracim worker -l info
```
In another terminal, start the Flask development server:
```
python manage.py runserver
```
Open a web browser and navigate to http://localhost:5000 to access the Tracim server.

Congratulations! You have successfully installed Tracim on your Arch Linux system. Enjoy using it!
