Open Event Server is an open-source platform for managing events. This tutorial will guide you through the installation of Open Event Server on Debian Latest using the command line.
First, we need to install the necessary dependencies. Open the terminal and type the following command:
sudo apt-get update
This command will update the package lists on your system. Next, we will install the dependencies required by Open Event Server. Run the following command:
sudo apt-get install -y git python3 python3-dev python3-pip nginx redis-server postgresql libpq-dev
Next, we will clone the Open Event Server repository from GitHub. Type the following command in the terminal:
git clone https://github.com/fossasia/open-event-server.git
This command will create a new directory named “open-event-server” in your current directory and download the source code from the GitHub repository.
To keep the dependencies of Open Event Server separate from the rest of the system, we will create a new virtual environment. Go to the directory where you cloned the repository and type the following command:
python3 -m venv env
This command will create a new virtual environment named “env” in your current directory.
Next, activate your virtual environment by running the following command:
source env/bin/activate
Now, you should see “(env)” at the beginning of your terminal prompt, indicating that you are in the virtual environment.
Before we can run Open Event Server, we need to install its dependencies. To do this, run the following command:
pip3 install -r requirements.txt
This command will install all the dependencies listed in the requirements.txt file in the Open Event Server directory.
Open Event Server requires PostgreSQL as the backend database. We need to create a new PostgreSQL database and user for Open Event Server.
First, log in to the PostgreSQL console by typing the following command:
sudo -u postgres psql
Next, create a new database and user by running the following commands:
CREATE DATABASE open_event;
CREATE USER open_event_user WITH PASSWORD 'password';
GRANT ALL PRIVILEGES ON DATABASE open_event TO open_event_user;
Replace “password” with a strong password for the open_event_user user. These commands will create a new database named “open_event” and a new user named “open_event_user”. We also grant all privileges to the new user on the new database.
Once you have done this, exit the PostgreSQL console by typing:
\q
Open Event Server requires several environment variables to be set. To do this, create a new file named .env in the Open Event Server directory and add the following lines:
FLASK_ENV=development
FLASK_APP=manager.py
SECRET_KEY=your-secret-key-here
DATABASE_URL=postgresql://open_event_user:password@localhost/open_event
REDIS_URL=redis://localhost:6379/0
Replace “your-secret-key-here” with a long, random string to use as the app secret key. Replace “password” with the password you set for the open_event_user user in Step 5.
Open Event Server requires a database to be initialized to work. To do this, run the following command:
flask db upgrade
This command will create the necessary tables in your PostgreSQL database.
We are now ready to start the Open Event Server. To do this, run the following command:
python3 manager.py runserver
This command will start the server on port 5000.
To access the Open Event Server from a web browser, we need to configure Nginx. First, create a new configuration file:
sudo nano /etc/nginx/sites-enabled/open-event
Paste the following configuration into the file:
server {
listen 80;
server_name example.com; # replace with your domain name
location / {
proxy_pass http://localhost:5000; # Open Event Server runs on port 5000
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
location /static {
alias /path/to/open-event-server/static/; # replace with your absolute path to Open Event Server static folder
}
}
Replace “example.com” with your own domain name, and replace “/path/to/open-event-server/static/” with the absolute path to the static folder in the Open Event Server directory.
Save and close the file.
Next, test the Nginx configuration by running the following command:
sudo nginx -t
If everything is working, reload the Nginx configuration by running the following command:
sudo service nginx reload
Open a web browser and navigate to http://example.com/, replacing “example.com” with your domain name. You should now see the Open Event Server login page.
Congratulations! You have successfully installed Open Event Server on Debian Latest.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
