Install and Configure Grafana in RHEL 7

Install and Configure Grafana in RHEL 7

Step 1 – Download & Install Grafana
Download Grafana RPM file RPM for Linux from https://grafana.com/grafana/download?platform=linux

# RHEL 7

Step 2 – Understand Grafana Installation details in RHEL/CENTOS

  1. Installs binary to /usr/sbin/grafana-server
  2. Copies init.d script to /etc/init.d/grafana-server
  3. Installs default file (environment vars) to /etc/sysconfig/grafana-server
  4. Copies configuration file to /etc/grafana/grafana.ini
  5. Installs systemd service (if systemd is available) name grafana-server.service
  6. The default configuration uses a log file at /var/log/grafana/grafana.log
  7. The default configuration specifies an sqlite3 database at /var/lib/grafana/grafana.db

Step 3 – Start the server (init.d service)

[code]$ sudo service grafana-server start[/code]

This will start the grafana-server process as the grafana user, which is created during package installation. The default HTTP port is 3000, and default user and group is admin.

Step 4 – Configure the Grafana server to start at boot time

[code]$ sudo /sbin/chkconfig –add grafana-server
$ sudo systemctl enable grafana-server.service
$ systemctl daemon-reload
$ systemctl start grafana-server
$ systemctl status grafana-server[/code]

Step 5 – Grafana server Environment file
The systemd service file and init.d script both use the file located at /etc/sysconfig/grafana-server for environment variables used when starting the back-end. Here you can override log directory, data directory and other variables.

Step 6 – Grafana server Log
By default Grafana will log to /var/log/grafana

Step 7 – Grafana Database
The default configuration specifies a sqlite3 database located at /var/lib/grafana/grafana.db. Please backup this database before upgrades.

You can also use MySQL or Postgres as the Grafana database, as detailed on
http://docs.grafana.org/installation/configuration/#database

Step 8 – Grafana configuration
The configuration file is located at /etc/grafana/grafana.ini. Go the Configuration page for details on all those options. You can add following data sources

  1. Graphite
  2. InfluxDB
  3. OpenTSDB
  4. Prometheus

Step 9 – Server side image rendering
Server side image (png) rendering is a feature that is optional but very useful when sharing visualizations, for example in alert notifications.

[code]$ sudo yum install fontconfig -y
$ sudo yum install freetype* -y
$ sudo yum install urw-fonts -y[/code]
