How To Install Grafana on CentOS 7

In this tutorial, we will show you how to install Grafana on CentOS 7. For those of you who didn’t know, Grafana is an open-source data visualization and tracking suite. It offers support for Graphite, Elasticsearch, Included, Prometheus, and a lot more databases. The application gives a beautiful dashboard and metric analytics, with the capability to control and create your own dashboard for your own apps or infrastructure performance monitoring.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Grafana on the CentOS 7 server.

Prerequisites

• A server running one of the following operating systems: CentOS 7.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Grafana on CentOS 7

Step 1. First, let’s start by ensuring your system is up-to-date.

yum clean all
yum -y update

Step 2. Install Grafana on CentOS 7.

First, Add a new Grafana repository:

cat <<EOF | sudo tee /etc/yum.repos.d/grafana.repo
[grafana]
name=grafana
baseurl=https://packagecloud.io/grafana/stable/el/6/$basearch
repo_gpgcheck=1
enabled=1
gpgcheck=1
gpgkey=https://packagecloud.io/gpg.key https://grafanarel.s3.amazonaws.com/RPM-GPG-KEY-grafana
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
EOF

Now we can start Grafana installation with the following command:

yum install grafana

After the installation process is finished, execute the following commands to start your Grafana service:

systemctl daemon-reload
systemctl start grafana-server
systemctl enable grafana-server

Step 3. Configure Firewall for Grafana.

By default, Grafana is running on port 3000. In case your server is using a firewall, open the port using the command below:

firewall-cmd --permanent --zone=public --add-port=3000/tcp
firewall-cmd --reload

Step 4. Accessing Grafana.

Grafana will be available on HTTP port 3000 by default. Open your favorite browser and navigate to http://your-domain.com:3000 and complete the required steps to finish the installation. If you are using a firewall, please open port 3000 to enable access to the control panel.
