How To Install mod_cluster on Fedora 34
Introduction
In this tutorial we learn how to install mod_cluster on Fedora 34.
What is mod_cluster
Mod_cluster is an httpd-based load balancer. Like mod_jk and mod_proxy, mod_cluster uses a communication channel to forward requests from httpd to one of a set of application server nodes. Unlike mod_jk and mod_proxy, mod_cluster leverages an additional connection between the application server nodes and httpd. The application server nodes use this connection to transmit server-side load balance factors and lifecycle events back to httpd via a custom set of HTTP methods, affectionately called the Mod-Cluster Management Protocol (MCMP). This additional feedback channel allows mod_cluster to offer a level of intelligence and granularity not found in other load balancing solutions.
We can use yum or dnf to install mod_cluster on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install mod_cluster.
Install mod_cluster on Fedora 34 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh

Fedora Modular 34 - x86_64 68 kB/s | 6.5 kB 00:00
Fedora 34 - x86_64 - Updates 3.5 kB/s | 6.2 kB 00:01
Fedora Modular 34 - x86_64 - Updates 17 kB/s | 5.9 kB 00:00
Metadata cache created.
After updating yum database, We can install mod_cluster using dnf by running the following command:
sudo dnf -y install mod_cluster
Install mod_cluster on Fedora 34 Using yum
