Install Latest Grafana on CentOS 8
There are different methods on how to install latest Grafana on CentOS 8. These include;
- Installing Grafana automatically via YUM package manager
- Installing Grafana manually via RPM package manager
- Installing Grafana via Grafana Standalone Binary
In this guide, we are going to learn how to install Grafana using all these three methods.
Runs system update
To begin with, update your system packages.
Installing Grafana automatically via YUM Package Manager
To install Grafana automatically via YUM package manager, there are two ways;
- Create the Grafana repos and install directly from these repos.
- Download Grafana RPM binary and install it using YUM package manager.
Installing Grafana from YUM repository
To install Grafana from YUM repository, you need to create YUM repos as follows
Well, there are two kinds repos; Enterprise and Open-source software (OSS) repos. Our demo involves the use of the later.
cat > /etc/yum.repos.d/grafana.repo << 'EOL' [grafana] name=grafana baseurl=https://packages.grafana.com/oss/rpm repo_gpgcheck=1 enabled=1 gpgcheck=1 gpgkey=https://packages.grafana.com/gpg.key sslverify=1 sslcacert=/etc/pki/tls/certs/ca-bundle.crt EOL
Once the repos are in place, run the command below to install latest Grafana on CentOS 8.
dnf install grafana -y
Instead of creating Grafana repos as shown above, you would simply download latest stable release Grafana RPM binary from Grafana downloads page and install it using YUM package manager.
Obtain the download link of the latest stable release version and pull the RPM binary using wget. Grafana 6.7.1 is the current stable release as of this writing.
Once the download completes, install it as follows;
dnf install grafana-6.7.1-1.x86_64.rpm
You can as well install it directly without having to download it;
dnf install https://dl.grafana.com/oss/release/grafana-6.7.1-1.x86_64.rpm
dnf localinstall https://dl.grafana.com/oss/release/grafana-6.7.1-1.x86_64.rpm
Installing Grafana manually via RPM package manager
To manually install Grafana via RPM package manager, you have to download the latest RPM binary installer from the Grafana downloads page.
Install required dependencies;
dnf install initscripts urw-fonts -y
Then install Grafana as follows;
rpm -Uvh grafana-6.7.1-1.x86_64.rpm
Installing Grafana via Grafana Standalone Binary
Grafana has a ready made standalone Linux binary tarball that can simply downloaded and installed on an appropriate Grafana directory.
Download the latest standalone binary tarball from Downloads page.
Once the download completes, you can extract the tarball to an appropriate directory. For example, to extract Grafana files to
tar xzf grafana-6.7.1.linux-amd64.tar.gz --strip-components=1 -C /usr/local/grafana
You should now have your Grafana and its configuration files on
bin conf LICENSE NOTICE.md public README.md scripts tools VERSION
Note that no initialization scripts are installed with this method.
