How to Install Redmine on nixOS

Redmine is a popular web-based project management tool with numerous features. In this tutorial, we will cover how to install Redmine on nixOS Latest. Please follow the steps below to accomplish the task.

Prerequisites

• A running nixOS Latest system
• Root access to the system or a user with sudo privileges
• Basic command-line skills

Step 1: Update the System Packages

Before installing Redmine, update the system packages by running the following command.

sudo nixos-rebuild switch

Step 2: Install PostgreSQL Database

Redmine requires PostgreSQL to store and fetch data from the database. To install PostgreSQL, run the following command.

sudo nix-env -i postgresql

Step 3: Create PostgreSQL User and Database

After installing PostgreSQL, create a new PostgreSQL user and database for Redmine by running the following command.

sudo su postgres -c "createuser -d -P redmine"
sudo su postgres -c "createdb -O redmine redmine"

You can set the PostgreSQL user and database name to whatever you want.

Step 4: Install Redmine

To install Redmine, we will use the nix package manager. To install Redmine, run the following command.

sudo nix-env -i redmine

Step 5: Configure Redmine

After the installation, you need to configure Redmine by creating a configuration file. Run the following command to create a configuration file.

sudo touch /etc/nixos/redmine.nix

Edit the configuration file with your favorite text editor:

sudo nano /etc/nixos/redmine.nix

And paste the following code.

{ config, lib, pkgs }: {

  services.redmine = {
    enable = true;

    # Replace 'redmine' with your desired hostname.
    virtualHost = "redmine.example.com";

    # Replace 'postgresql-server' with your PostgreSQL service name.
    database = "postgresql-server";
    databaseName = "redmine";
    databaseUser = "redmine";
    databasePassword = "your-password";

    # Replace the email section with your SMTP server details to be able to send emails.
    email = {
      enable = true;
      smtpAddress = "smtp.gmail.com";
      smtpPort = 587;
      domain = "example.com";
      username = "[email protected]";
      password = "your-email-password-here";
    };

    # Replace the secret key base section with a randomly generated key.
    secretKeyBase = "helloworld";
  };
}

Replace the fields with your respective values. For example, you can use a website like PasswordGenerator.net to generate a password for the PostgreSQL user.

After making the necessary changes, save and close the file.

Step 6: Activate the Redmine Service

Activate the Redmine service by running the following command.

sudo nixos-rebuild switch

The service should be up and running. You can access it in your web browser by navigating to the hostname you set in the configuration file.
