Install by RPM Package (Red Hat Linux)
This article explains how to install stable versions of
fluent-package rpm packages, the stable Fluentd distribution packages maintained by Fluentd Project and calyptia-fluentd which is maintained by Calyptia, Inc..Fluentd is written in Ruby for flexibility, with performance-sensitive parts in C. However, some users may have difficulty installing and operating a Ruby daemon.
That is why Fluentd Project provides the stable distribution of Fluentd, called
fluent-package (formerly known as td-agent). The differences between Fluentd and fluent-package can be found here.Our Calyptia also knows that Fluentd is written in Ruby for flexibility, with performance-sensitive parts in C. However, some users may have difficulty installing and operating a Ruby daemon. And
td-agent is still seated on Ruby 2.7 due to compatibility reasons and Ruby versioning policy, calyptia-fluentd uses Ruby 3 instead of Ruby 2.7 for now.That is why Calyptia, Inc. provides the alternative stable distribution of Fluentd, called
calyptia-fluentd. The differences between td-agent and calyptia-fluentd are bundled and running Ruby versions for now.This installation guide is for
fluent-package v5 and calyptia-fluentd v1. fluent-package v5 and calyptia-fluentd use fluentd v1 in the core. See fluent-package-v5-vs-td-agent or td-agent-v2-vs-v3-vs-v4 for the comparison and supported OS.NOTE:
- About deprecated Treasure Agent (td-agent) 3 will not be maintained anymore, see Install by DEB Package v3.
fluent-packagewill be shipped in two flavors - normal release version and LTS (Long Term Support) version. See Scheduled support lifecycle announcement about Fluent Package about difference between this two flavors.
It is highly recommended to set up
ntpd on the node to prevent invalid timestamps in the logs. See Pre-installation Guide.Download and execute the install script with
curl:# fluent-package 5 (LTS)
$ curl -fsSL https://toolbelt.treasuredata.com/sh/install-redhat-fluent-package5-lts.sh | sh
# fluent-package 5
$ curl -fsSL https://toolbelt.treasuredata.com/sh/install-redhat-fluent-package5.sh | sh
Executing this script will automatically install
fluent-package on your machine. This shell script registers a new rpm repository at /etc/yum.repos.d/fluent-package.repo (or /etc/yum.repos.d/fluent-package-lts.repo) and installs fluent-package.We use
$releasever for repository path in the script and $releasever should be the major version only like "7". If your environment uses some other format like "7.2", change it to the major version only or set up .repo file manually.For Amazon Linux 2023:
# fluent-package 5 (LTS)
$ curl -fsSL https://toolbelt.treasuredata.com/sh/install-amazon2023-fluent-package5-lts.sh | sh
# fluent-package 5
$ curl -fsSL https://toolbelt.treasuredata.com/sh/install-amazon2023-fluent-package5.sh | sh
For Amazon Linux 2:
# fluent-package 5 (LTS)
$ curl -fsSL https://toolbelt.treasuredata.com/sh/install-amazon2-fluent-package5-lts.sh | sh
# fluent-package 5
$ curl -fsSL https://toolbelt.treasuredata.com/sh/install-amazon2-fluent-package5.sh | sh
