Or install manually using rpm.

$ sudo yum install initscripts fontconfig $ sudo rpm -Uvh grafana-2.1.3-1.x86_64.rpm

Install via YUM Repository

Add the following to a new file at /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

There is also a testing repository if you want beta or release candidates.

baseurl=https://packagecloud.io/grafana/testing/el/6/$basearch

Then install Grafana via the yum command.

$ sudo yum install grafana

RPM GPG Key

The RPMs are signed, you can verify the signature with this public GPG key. Package details

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

Start the server (init.d service)

You can start Grafana by running:

$ sudo service grafana-server start

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.

To configure the Grafana server to start at boot time:

$ sudo /sbin/chkconfig –add grafana-server

Start the server (via systemd)

$ systemctl daemon-reload $ systemctl start grafana-server $ systemctl status grafana-server

Enable the systemd service to start at boot

sudo systemctl enable grafana-server.service

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. Logging

By default Grafana will log to /var/log/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 the configuration page. Configuration

The configuration file is located at /etc/grafana/grafana.ini. Go the Configuration page for details on all those options. Adding data sources
