How to install Corteza on nixOS Latest

Corteza is an advanced and configurable open-source digital business platform. This tutorial will guide you through the process of installing Corteza on nixOS Latest.

Prerequisites

Before starting the installation, make sure your system meets the following requirements:

• You have a running nixOS Latest system.
• You have root privileges or sudo access.
• You have an internet connection.

Step 1 - Install Corteza dependencies

Corteza requires several system dependencies to be installed on your nixOS Latest system. Install the following system dependencies using the nix command:

$ sudo nix-env -i python3 python3Packages.pip python3Packages.setuptools python3Packages.dev python3Packages.psycopg2 python3Packages.pillow python3Packages.cryptography python3Packages.git

Step 2 - Install Corteza using pip

Corteza can be installed using pip, Python's package installer. Install Corteza using the following command:

$ sudo pip3 install cortezaproject 

Step 3 - Install and Configure Corteza Database

By default, Corteza uses SQLite as its database. However, you can configure it with other databases such as PostgreSQL, MySQL, or MariaDB.

In this tutorial, we will configure Corteza with PostgreSQL. Install PostgreSQL and create a database for Corteza:

$ sudo nix-env -i postgresql
$ sudo -i -u postgres
postgres$ createdb cortezadb
postgres$ psql cortezadb
cortezadb=# CREATE USER cortezau WITH PASSWORD 'cortezapassword';
cortezadb=# GRANT ALL PRIVILEGES ON DATABASE cortezadb TO cortezau;
cortezadb=# \q
postgres$ exit

Step 4 - Configure Corteza

Corteza configuration files are located at /etc/cortezaproject. Use your preferred text editor to create a configuration file for Corteza:

$ sudo vi /etc/cortezaproject/corteza_config.toml

Add the following configuration to the file, replacing the database connection details with your PostgreSQL credentials:

[database]
engine = "postgresql"
host = "localhost"
port = "5432"
database = "cortezadb"
user = "cortezau"
password = "cortezapassword"

Save and close the file.

Step 5 - Configure Corteza Services

Corteza consists of several services, including the Corteza API, WebSocket server, Notification server, and others. To start these services, create and enable a systemd unit file for each service.

Create a Corteza API systemd unit file:

$ sudo vi /etc/systemd/system/corteza-api.service

Add the following configuration to the file:

[Unit]
Description=Corteza API Service
After=network.target

[Service]
User=root
Group=root
WorkingDirectory=/usr/local/bin
Environment="CORTEZA_CONFIG=/etc/cortezaproject/corteza_config.toml"
ExecStart=/usr/local/bin/corteza-server api

[Install]
WantedBy=multi-user.target

Save and close the file.

Create a WebSocket server systemd unit file:

$ sudo vi /etc/systemd/system/corteza-ws.service

Add the following configuration to the file:

[Unit]
Description=Corteza WebSocket Service
After=network.target

[Service]
User=root
Group=root
WorkingDirectory=/usr/local/bin
Environment="CORTEZA_CONFIG=/etc/cortezaproject/corteza_config.toml"
ExecStart=/usr/local/bin/corteza-server ws

[Install]
WantedBy=multi-user.target

Save and close the file.

Create a Notification server systemd unit file:

$ sudo vi /etc/systemd/system/corteza-notify.service

Add the following configuration to the file:

[Unit]
Description=Corteza Notification Service
After=network.target

[Service]
User=root
Group=root
WorkingDirectory=/usr/local/bin
Environment="CORTEZA_CONFIG=/etc/cortezaproject/corteza_config.toml"
ExecStart=/usr/local/bin/corteza-server notify

[Install]
WantedBy=multi-user.target

Save and close the file.

Step 6 - Start and Enable Corteza Services

Start and enable the Corteza services with the following commands:

$ sudo systemctl daemon-reload
$ sudo systemctl start corteza-api
$ sudo systemctl start corteza-ws
$ sudo systemctl start corteza-notify
$ sudo systemctl enable corteza-api
$ sudo systemctl enable corteza-ws
$ sudo systemctl enable corteza-notify
