Installing HAProxy on CentOS 8

HAProxy is a free, open-source load balancer and proxy server software that provides high availability, load balancing, and proxying for TCP and HTTP applications. It distributes incoming requests to a set of backend servers based on a configured load balancing algorithm, enabling optimal utilization of server resources.

To install HAProxy on CentOS 8, follow these steps:

sudo dnf update -y

sudo dnf install haproxy -y

Edit the HAProxy configuration file /etc/haproxy/haproxy.cfg to define your backend servers and load balancing algorithm:

sudo vi /etc/haproxy/haproxy.cfg

Here's an example configuration:

global
    log /dev/log local0
    log /dev/log local1 notice
    chroot /var/lib/haproxy
    stats socket /run/haproxy/admin.sock mode 660 level admin expose-fd listeners
    stats timeout 30s
    user haproxy
    group haproxy
    daemon

defaults
    log global
    mode http
    option httplog
    option dontlognull
    timeout connect 5000
    timeout client 50000
    timeout server 50000

frontend myfrontend
    bind 192.168.1.10:80
    mode http
    default_backend mybackend

backend mybackend
    mode http
    balance roundrobin
    server server1 192.168.1.11:80 check
    server server2 192.168.1.12:80 check

Save the file and exit.

sudo systemctl start haproxy
sudo systemctl enable haproxy

HAProxy should now be installed and running on your CentOS 8 system. You can access the HAProxy statistics page by visiting http://your-server-ip:8080/stats in a web browser, replacing your-server-ip with the IP address of your server.
