Ralph is an asset management tool that can help you discover, inventory, and audit your infrastructure. In this tutorial, we will demonstrate how to install Ralph on the latest version of NixOS.
Before we begin, ensure that you have the following:
The first step in installing Ralph on NixOS is to install PostgreSQL. Run the following command to install the PostgreSQL package:
$ sudo nix-env -i postgresql
Next, create the Ralph user and database in PostgreSQL by entering the following commands:
$ sudo su postgres -c "createuser -dralph"
$ sudo su postgres -c "createdb -E UTF8 -O ralph ralph"
Now, install Ralph on your NixOS by running the following command:
$ sudo nix-env -iA nixos-ralph
After successfully installing, we need to configure Ralph. Open the /etc/ralph/ralph.conf file and update the PostgreSQL access credentials to match the credentials you created in step 2.
DATABASES = {
'default': {
'ENGINE': 'ralph.data_center.backends.postgres',
'NAME': 'ralph',
'USER': 'ralph',
'PASSWORD': 'your_password',
'HOST': 'localhost',
'PORT': '',
'CONN_MAX_AGE': 0,
},
}
Save the file when you're done.
Now we need to set up the Ralph database schemas by running the following command:
$ sudo ralph migrate
Finally, start Ralph by running the following command:
$ sudo systemctl enable ralph
$ sudo systemctl start ralph
Congratulations! You have successfully installed Ralph on NixOS. You can now access your Ralph instance by visiting the http://localhost:8000
in your web browser.
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!
