In this tutorial, we are going to learn how to install and configure Filebeat on CentOS 8. Filebeat is one of the Elastic Stack beats, the data shippers for Elasticsearch.
Filebeat is a lightweight shipper for forwarding and centralizing log data. Installed as an agent on your servers, Filebeat monitors the log files or locations that you specify, collects log events, and forwards them either to Elasticsearch or Logstash for indexing.
Install and Configure Filebeat on CentOS 8
I assume that you have a running Elastic Stack to which you will ship data to for processing using Filebeat. If not, follow the following guides to learn how to install and configure ES.
Install Elastic Stack Repos on CentOS 8
Filebeat is not available on the default CentOS 8 and therefore you need to install Elastic Stack repos.
Install Elastic Stack repo GPG signing key
sudo rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch
Next, install Elastic Stack repo on CentOS 8;
cat > /etc/yum.repos.d/elasticstack.repo << EOL [elasticstack] name=Elastic repository for 7.x packages baseurl=https://artifacts.elastic.co/packages/7.x/yum gpgcheck=1 gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch enabled=1 autorefresh=1 type=rpm-md EOL
Once the repos are in place, you can install Filebeat by running the command below;
dnf install filebeat
Install Filebeat using RPM Package
Should you choose to install Filebeat on CentOS 8 using the RPM package, simply grab the link to the latest stable release version of the filebeat RPM package from Filebeat download's page and run either of the command below;
dnf install https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-7.7.1-x86_64.rpm
wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-7.7.1-x86_64.rpm rpm -vi filebeat-7.7.1-x86_64.rpm
dnf localinstall filebeat-7.7.1-x86_64.rpm
Start and enable Filebeat to run on system boot;
systemctl enable --now filebeat
To check the status;
systemctl status filebeat

Filebeat is now ready to read logs and event data and ship them to the
Elasticsearch, the search and analytics engine, or to
Logstash, for further processing and transformation before being stashed to Elasticsearch.
Follow the link below to learn how to configure Filebeat to collect and ship logs from the system to Elastic stack.
That marks the end of our guide on how to install and configure Filebeat on CentOS 8 for shipping system logs to be processed on an Elastic Stack server.
