This guide intends to teach you to Set up Grafana visualization and analytics software on Rocky Linux 9.
Grafana is an open-source solution for running data analytics with the help of metrics that give us an insight into the complex infrastructure and massive amount of data that our services deal with, with the use of customizable dashboards.
Grafana connects with every possible data source such as Graphite, Prometheus, Influx DB, ElasticSearch, MySQL, PostgreSQL, etc. The solution’s open-source nature helps us write custom plugins to connect with any data source of our choice.
Steps To Set up Grafana on Rocky Linux 9
To complete this guide, you must log in to your server as a non-root user with sudo privileges and set up a basic firewall. For this purpose, you can visit this guide on Initial Server Setup with Rocky Linux 9.
Grafna Installation on Rocky Linux 9
First, you need to update your local package index with the following command:
sudo dnf update
You can install Grafana in a few ways on your server. In this guide, you will learn to install Grafana by using an RPM package.
sudo wget https://dl.grafana.com/oss/release/grafana-VERSION.x86_64.rpm
sudo wget https://dl.grafana.com/oss/release/grafana-9.1.6-1.x86_64.rpm
Install Grafana on Rocky Linux 9
Then, use the following command to install Grafana:
sudo dnf install grafana-9.1.6-1.x86_64.rpm
Manage Grafana Service
Once the installation is complete, reload the system daemon with the command:
sudo systemctl daemon-reload
Now start and enable the Grafana service by running the commands below:
# sudo systemctl start grafana-server # sudo systemctl enable grafana-server
Verify your Grafana service is active and running on Rocky Linux 9:
sudo systemctl status grafana-server
Output ● grafana-server.service - Grafana instance Loaded: loaded (/usr/lib/systemd/system/grafana-server.service; enabled; v> Active: active (running) since Thu 2022-09-22 04:09:53 EDT; 11s ago Docs: http://docs.grafana.org Main PID: 5010 (grafana-server) Tasks: 7 (limit: 23609) Memory: 39.7M CPU: 942ms CGroup: /system.slice/grafana-server.service └─5010 /usr/sbin/grafana-server --config=/etc/grafana/grafana.ini
Configure Firewall For Grafana
The Grafana server listens on port 3000 by default, you can verify this with the command below:
sudo ss -plunt|grep grafana
Output tcp LISTEN 0 4096 *:3000 *:* users:(("grafana-server",pid=5010,fd=8))
At this point, you need to allow traffic for Grafana on port 3000 through the firewall on Rocky Linux 9. To do this, run the following command:
sudo firewall-cmd --add-port=3000/tcp --permanent
Now reload the firewall to apply the new rules:
sudo firewall-cmd --reload
Note: You can customize Grafana by editing the configuration file at /etc/grafana/grafana.ini to suit your preference.
Access Grafana Dashboard
At this step, you can access the Grafana web interface on Rocky Linux 9 by typing your server’s IP address in your web browser followed by 3000:
You will see the Grafana login screen. At this window, enter admin for the username and password and click Log in.
Then, change the default password of Grafana and click submit.
At this point, you will see the Grafana welcome dashboard screen:
The Grafana dashboard is pretty equipped with various features and is continually evolving which helps us make sense of complex data. From displaying graphs to heatmaps, histograms, Geo maps, and so on.
At this point, you have learned to Set up Grafana on Rocky Linux 9.
