Install on Redhat / CentOS

Fluent Bit is distributed as td-agent-bit package and is available for the latest stable CentOS system. The following architectures are supported

  • x86_64

  • aarch64 / arm64v8

Configure Yum

We provide td-agent-bit through a Yum repository. In order to add the repository reference to your system, please add a new file called td-agent-bit.repo in /etc/yum.repos.d/ with the following content:

[td-agent-bit]
name = TD Agent Bit
baseurl = https://packages.fluentbit.io/centos/7/$basearch/
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://packages.fluentbit.io/fluentbit.key
enabled=1

note: we encourage you always enable the gpgcheck for security reasons. All our packages are signed.

Updated key from March 2022

From the 1.9.0 and 1.8.15 releases please note that the GPG key has been updated at so ensure this new one is added.

The GPG Key fingerprint of the new key is:

C3C0 A285 34B9 293E AF51  FABD 9F9D DC08 3888 C1CD
Fluentbit releases (Releases signing key) <releases@fluentbit.io>

The GPG Key fingerprint of the old key is:

F209 D876 2A60 CD49 E680 633B 4FF8 368B 6EA0 722A

Install

Once your repository is configured, run the following command to install it:

$ yum install td-agent-bit

Now the following step is to instruct Systemd to enable the service:

$ sudo service td-agent-bit start

If you do a status check, you should see a similar output like this:

$ service td-agent-bit status
Redirecting to /bin/systemctl status  td-agent-bit.service
● td-agent-bit.service - TD Agent Bit
   Loaded: loaded (/usr/lib/systemd/system/td-agent-bit.service; disabled; vendor preset: disabled)
   Active: active (running) since Thu 2016-07-07 02:08:01 BST; 9s ago
 Main PID: 3820 (td-agent-bit)
   CGroup: /system.slice/td-agent-bit.service
           └─3820 /opt/td-agent-bit/bin/td-agent-bit -c etc/td-agent-bit/td-agent-bit.conf
...

The default configuration of td-agent-bit is collecting metrics of CPU usage and sending the records to the standard output, you can see the outgoing data in your /var/log/messages file.

The previous key is still available at and may be required to install previous versions.
