How to Install Vigil on Fedora CoreOS Latest

Vigil is a server monitoring tool that provides real-time alerting, reporting, and graphing capabilities. In this tutorial, we will go through the steps to install Vigil on Fedora CoreOS latest.

Step 1: Install Rust

Rust is a programming language that is used to build Vigil. Therefore, we need to install Rust before installing Vigil. Here's how to install Rust on Fedora CoreOS:

Run the following command to download and install Rustup:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Follow the instructions to complete the Rust installation.

Step 2: Install Vigil

Now that Rust is installed, we can proceed to install Vigil:

Run the following command to download and install Vigil:
```
cargo install vigil-server
```
Vigil should now be installed. To verify the installation, run the following command to start Vigil:
```
vigil-server
```
You should see output similar to the following:
```
INFO: Started HTTP server: 127.0.0.1:3030
INFO: Started WebSocket server: 127.0.0.1:8080
```
With Vigil running, you can now open a web browser and navigate to http://localhost:3030 to access the Vigil web interface.

Step 3: Start Vigil on Boot

To start Vigil automatically when the system boots up, we need to create a systemd service file:

Run the following command to create the vigil.service file:
```
sudo vi /etc/systemd/system/vigil.service
```

Paste the following contents into the vigil.service file:

[Unit]
Description=Vigil Server

[Service]
User=vigil
Group=vigil
ExecStart=/usr/local/cargo/bin/vigil-server
Restart=always

[Install]
WantedBy=multi-user.target

Save and close the file.
Run the following command to reload the systemd configuration:
```
sudo systemctl daemon-reload
```
Finally, run the following command to start the Vigil service:
```
sudo systemctl start vigil
```
You can now check the status of the Vigil service by running the following command:
```
sudo systemctl status vigil
```

Conclusion

Congratulations! You have successfully installed and started Vigil on Fedora CoreOS latest. You can now use Vigil to monitor your servers and receive real-time alerts when something goes wrong.
