This tutorial will guide you through the installation process for the Calagator event aggregator on NixOS Latest.
Before you start, make sure you have the following:
To ensure that the system is up to date, update the package index and upgrade the system packages by running the following command:
sudo nixos-rebuild switch
To install Calagator, we need to install the following dependencies:
To install these dependencies using the Nix package manager, create a new Nix file called calagator.nix
:
sudo nano /etc/nixos/calagator.nix
Paste the following code into the file:
{ pkgs }:
with pkgs;
let
rubyPackages = ruby_2_6;
nodePackages = nodejs-10_x;
in
buildEnv {
name = "calagator-env";
paths = [
postgresql
rubyPackages
nodePackages
];
buildInputs = [
zlib
openssl
readline
libxml2
libxslt
imagemagick
curl
git
gcc
make
postgresql
nodejs-10_x
];
}
Save and close the file.
Now, run the following command to install the dependencies:
sudo nix-env -i -f /etc/nixos/calagator.nix
We will now download the latest version of Calagator and configure it.
Create a new directory for Calagator:
sudo mkdir /var/www/calagator
Clone the Calagator repository:
sudo git clone https://github.com/calagator/calagator.git /var/www/calagator
Create a new configuration file:
sudo cp /var/www/calagator/config/settings.yml.example /var/www/calagator/config/settings.yml
Edit the configuration file:
sudo nano /var/www/calagator/config/settings.yml
Set the following variables to match your configuration:
database: calagator
username: your_username
password: your_password
host: 127.0.0.1
port: 5432
environment: production
Save and close the file.
Run the following commands to install the Calagator dependencies:
cd /var/www/calagator
sudo gem install bundler
sudo bundle install --without development test --jobs $(nproc)
sudo npm install -g phantomjs-prebuilt
sudo npm install -g coffee-script
sudo npm install
sudo chmod -R 777 tmp/
Create a new PostgreSQL database and user for Calagator:
sudo su postgres
createdb calagator
createuser --createdb --encrypted --pwprompt calagator
Enter a password for the calagator
user and remember it.
Update the PostgreSQL configuration file:
sudo nano /var/lib/pgsql/data/pg_hba.conf
Add the following lines to the file:
local calagator calagator trust
host calagator calagator 127.0.0.1/32 md5
Save and close the file.
We will now migrate the database schema:
cd /var/www/calagator
sudo RAILS_ENV=production bundle exec rake db:migrate
Finally, start the Calagator server:
cd /var/www/calagator
sudo RACK_ENV=production sudo shotgun -s thin -o 0.0.0.0 -p 3000 config.ru
You should now be able to access Calagator at http://localhost:3000
.
Calagator is now installed and running on your NixOS Latest system. You can configure it further by following the official Calagator documentation.
