HA Galera Cluster with HAProxy and Keepalived: Simplifying the Setup
When managing a database cluster in production, ensuring high availability and load balancing is critical. Initially, we used GLB (Global Load Balancer) on each webserver to balance connections to our four Galera MySQL servers. GLB worked fine, but maintaining it across multiple webservers quickly became cumbersome. So we decided to simplify and centralize our setup…
Setting Up VRRP and Keepalived for Load Balancer Redundancy with HAProxy
To ensure high availability and redundancy in our load-balancing environment, we can leverage VRRP (Virtual Router Redundancy Protocol) with Keepalived. By configuring VRRP across two servers, we can assign virtual IPs (VIPs) that automatically migrate between servers in the event of a failure. This setup enables seamless failover, with each server acting as both a…
Understanding VRRP: Ensuring Network Resilience through Redundancy
The Virtual Router Redundancy Protocol (VRRP) is a network protocol designed to increase the availability of routing paths in a network. By creating a virtual router, VRRP allows multiple routers to work together, ensuring that if the primary router fails, a backup router can take over seamlessly. This failover capability is essential in networks where…
