Install Grafana in Linux Systems

1. We will install Grafana from its official YUM or APT repositories, so that you can update it using your default package manager.

Install Grafana on Debian and Ubuntu

$ echo "deb stretch main" | sudo tee -a /etc/apt/sources.list
$ curl | sudo apt-key add -
$ sudo apt-get update
$ sudo apt-get install grafana

Install Grafana on CentOS, RHEL and Fedora

# echo "[grafana]
sslcacert=/etc/pki/tls/certs/ca-bundle.crt" | sudo tee /etc/yum.repos.d/grafana.repo
# yum install grafana

2. After installing Grafana, you can find important files in the following locations:

  • Installs binary to /usr/sbin/grafana-server
  • Installs Init.d script to /etc/init.d/grafana-server
  • Creates default file (environment vars) to /etc/default/grafana-server
  • Installs configuration file to /etc/grafana/grafana.ini
  • Installs systemd service name grafana-server.service
  • The default configuration sets the log file at /var/log/grafana/grafana.log
  • The default configuration specifies an sqlite3 db at /var/lib/grafana/grafana.db
  • Installs HTML/JS/CSS and other Grafana files at /usr/share/grafana

3. Next, start the Grafana service, check if it is up and running, then enable it to auto-start at boot time as follows. By default, the process is run as the grafana user (created during the installation process), and listens on HTTP port 3000.

Start Grafana Server (via Systemd)

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

Start Grafana Server (via init.d)

# service grafana-server start
# service grafana-server status
# sudo update-rc.d grafana-server defaults [On Debian/Ubuntu]
# /sbin/chkconfig --add grafana-server [On CentOS/RHEL/Fedora]

4. If your system has a firewall enabled by default, you need to open the port 3000 in the firewall to allow client requests to the grafana process.

----------- [On Debian/Ubuntu] -----------
$ sudo ufw allow 3000/tcp
$ sudo ufw reload
----------- [On CentOS/RHEL/Fedora] ----------- # firewall-cmd --permanent --add-port=3000/tcp
# firewall-cmd --reload
