We will elaborate in this article on how to Grafana monitoring dashboard on CentOS 8.<\/p>\n

Prerequisites<\/strong><\/h2>\n

You are required to log in as a root user on your system for running all administrative commands.<\/p>\n

Installation of Grafana on CentOS 8 Linux distribution<\/strong><\/h2>\n

Grafana installation complete into the number of steps that are mentioned below:<\/p>\n

Step 1: Add Grafana Yum repository<\/strong><\/h3>\n

To install Grafana using the yum package manager, add the Grafana repository to the local yum repository. For this purpose, open the terminal using the \u2018Activities\u2019 sections and click on the terminal icon from the left sidebar of the CentOS 8 desktop. Now, create a new file \u2018grafana.repo\u2019 in the Yum repository and execute the following commands with administrative privileges on the terminal application:<\/p>\n

$ cat <<EOF | sudo tee \/etc\/yum.repos.d\/grafana.repo<\/pre>\n
[grafana]\r\n\r\nname=grafana\r\n\r\nbaseurl=https:\/\/packages.grafana.com\/oss\/rpm\r\n\r\nrepo_gpgcheck=1\r\n\r\nenabled=1\r\n\r\ngpgcheck=1\r\n\r\ngpgkey=https:\/\/packages.grafana.com\/gpg.key\r\n\r\nsslverify=1\r\n\r\nsslcacert=\/etc\/pki\/tls\/certs\/ca-bundle.crt\r\n\r\nEOF<\/pre>\n
<\/p>\n
Enter the sudo password and the following output shows on the terminal:<\/p>\n
<\/p>\n
Step 2: Update yum repository<\/strong><\/h3>\n
Update the available system packages by using the below-given command:<\/p>\n
$ sudo dnf makecache<\/pre>\n
<\/p>\n
Now, all packages of your system are updated.<\/p>\n
Step 3:\u00a0 Install Grafana using Yum<\/strong><\/h3>\n
Once the grafana repository is added and configured on your system, install the grafana by executing the below-mentioned command:<\/p>\n
$ sudo dnf -y install grafana<\/pre>\n
<\/p>\n
The above command imports the GPG key and installs all required grafana packages on CentOS 8.<\/p>\n
<\/p>\n
Once the installation of grafana is completed, use the below-mentioned command to verify the installation and see the details of grafana package:<\/p>\n
$ rpm -qi grafana<\/pre>\n
<\/p>\n
Step 4: Check the Grafana systemd service\u00a0<\/strong><\/h3>\n
The systemd manages the grafana service on your system. Therefore, enable it by running the \u2018systemctl\u2019 command as follows:<\/p>\n
$ sudo systemctl enable --now grafana-server.service<\/pre>\n
<\/p>\n
Step 5: Start Grafana systemd service<\/strong><\/h3>\n
Now, grafana systemd service is enabled. Start service and then check \u2018running or Active\u2019 status of grafana service by running the below-mentioned commands:<\/p>\n
$ systemctl start grafana-server.service<\/pre>\n
$ systemctl status grafana-server.service<\/pre>\n
<\/p>\n
Step 6: Enable firewall rules<\/strong><\/h3>\n
By default, the grafana service runs on port 3000. So, if firewalld service is running on your system then, run the following command to allow access to port 3000 for grafana service:<\/p>\n
\u00a0$ sudo firewall-cmd --add-port=3000\/tcp --permanent<\/pre>\n
$ sudo firewall-cmd \u2013reload<\/pre>\n
<\/p>\n
To make sure everything is working correctly, use the below-given command:<\/p>\n
$ sudo firewall-cmd --list-all | grep ports<\/pre>\n
<\/p>\n
Step 7: Grafana Configurations<\/strong><\/h3>\n
All grafana configurations related to port and path are stored in the \u2018\/etc\/grafana\/grafana.ini\u2019 configuration file. You can modify \u2018http_port = 3000\u2019\u00a0according to your system requirements. The grafana log is by default written in the \u2018\/var\/log\/grafana\u2019 directory. The grafana SQLite database can be found under \u2018\/var\/lib\/grafana\/grafana.db\u2019.<\/p>\n
Step 8:\u00a0 Launch Grafana on CentOS 8 through Web UI<\/strong><\/h3>\n
Launch the Grafana web user interface on CentOS 8. Open the browser and type the following URL in the address bar:<\/p>\n
http:\/\/localhost:3000<\/pre>\n
Or<\/p>\n
http:\/\/server-ip:3000<\/a><\/pre>\n
The Grafana web UI shows in your browser as follows:<\/p>\n
<\/p>\n
Enter the username=admin and password= admin to access the Grafana dashboard. After that, the following Grafana dashboard display in the browser:<\/p>\n
<\/p>\n
Congratulations! Grafana installation is completed. Now, you can use the grafana monitoring dashboard on CentOS 8 system.<\/p>\n
