In this tutorial, we will guide you through the installation process of Shield on the latest version of NixOS. Shield is a popular open-source tool used for backing up and restoring data for cloud-native environments. It provides a simple and secure way to protect databases, file systems, and other cloud resources.
Before we begin, make sure you have the following requirements in place:
Shield requires some dependencies to be installed first. Open your terminal window and run the following command to install the necessary dependencies:
$ sudo nix-env -i -f '<nixpkgs>' libgit2 libressl
This command uses the "nix-env" tool to install the required dependencies, "libgit2" and "libressl".
Next, we need to get the Shield source code from its Github repository. Run the following command in your terminal window to clone the Shield repository:
$ git clone https://github.com/starkandwayne/shield /tmp/shield
This command clones the Shield source code from the Github repository and stores it in the "/tmp/shield" directory.
With the Shield source code in place, we can now build and install it. Run the following commands in your terminal window to compile and install Shield:
$ cd /tmp/shield
$ nix-shell
$ make
$ sudo make install
The first command navigates to the "/tmp/shield" directory, where the Shield source code is stored. The "nix-shell" command starts the nix environment with all the necessary dependencies installed. The "make" command compiles the Shield source code, and the "sudo make install" command installs it on your system.
Once Shield is installed, we need to configure it to work correctly on our system. Run the following commands in your terminal window to create the Shield configuration file and edit it:
$ sudo mkdir /etc/shield
$ sudo touch /etc/shield/shield.yml
$ sudo nano /etc/shield/shield.yml
The first command creates a new directory to store the Shield configuration files. The second command creates a new empty configuration file. The third command opens the configuration file in the "nano" text editor, where you can add your desired configuration settings.
There are many configuration options available for Shield. You can refer to the official documentation for a complete list of available options.
With the Shield installation and configuration complete, we can now start the Shield service. Run the following command in your terminal window to start Shield:
$ sudo systemctl start shield
This command starts the Shield service on your system. If you want Shield to start automatically upon system boot, run the following command:
$ sudo systemctl enable shield
In this tutorial, we have guided you through the installation process of Shield on the latest version of NixOS. With Shield installed, you can now use it to backup and restore your cloud resources efficiently and securely.
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!
