How to Install Grafana on OpenBSD

Grafana is a popular open source platform that allows you to visualize and analyze data from various sources. In this tutorial, we will guide you on how to install Grafana on OpenBSD.

Prerequisites

Before starting, make sure that your system meets the following requirements:

OpenBSD installed and up-to-date
Access to a terminal with sudo privileges
A web browser
wget should be installed

Step 1 — Installing Dependencies

Before you can install Grafana, you will need to install some dependencies. Open a terminal and use the following command to install the required packages:

sudo pkg_add -v wget fontconfig

Step 2 — Downloading and Installing Grafana

Use the following command to download the latest package of Grafana:

wget https://dl.grafana.com/oss/release/grafana-7.3.3.linux-amd64.tar.gz

Once the download is complete, extract the package using the following command:
```
tar -zxvf grafana-7.3.3.linux-amd64.tar.gz
```
Now, move the extracted directory (grafana-7.3.3) to the /usr/local directory using the following command:
```
sudo mv grafana-7.3.3 /usr/local/
```

Step 3 — Starting and Enabling Grafana

Use the following command to start Grafana:

sudo /usr/local/grafana-7.3.3/bin/grafana-server

Open a web browser and navigate to http://127.0.0.1:3000. Grafana's login page will appear.
Note: By default, the Grafana login username and password is "admin". You will be prompted to change the password on login.

Finally, to start Grafana automatically on system boot, create a systemd service for it. First, create a new file /etc/rc.d/grafana with the following contents:

#!/bin/sh
#
# /etc/rc.d/grafana
#
start_daemon() {
    /usr/local/grafana-7.3.3/bin/grafana-server
}
stop_daemon() {
    pkill grafana-server
}
case "$1" in
    start) start_daemon;;
    stop) stop_daemon;;
    restart) stop_daemon; sleep 1; start_daemon;;
esac

Make the file executable:
```
chmod +x /etc/rc.d/grafana
```
Now enable the Grafana service to start at boot:
```
sudo rcctl enable grafana
```

Conclusion

Grafana is now installed and ready to use on your OpenBSD system. You can begin exploring the software's features, importing data sources, and displaying insights using custom dashboards.
