It is used by the world's highly trafficked websites, including Twitter, Tumblr, Amazon Web Service, and GoDaddy to spread incoming requests across multiple endpoints. Mysql -uroot -p -h10.10.10.HAProxy (High Availability Proxy) is an intelligent software solution that offers load balancing and a high level of uptime performance for TCP- and HTTP-based applications. Output at the second hit : Enter password: Mysql -uroot -p -h10.10.10.7 -e "show variables like 'wsrep_node_name' " mysql -uroot -p -h10.10.10.7 -e "show variables like 'wsrep_node_name' " use the below command, So we can easily differentiate between servers.

HAProxy: haproxy 10.10.10.7 Step 1 – Install HAProxy There are 3 Galera running with mysql and listening on port 3306 and one HAProxy server. Which will balance load and transfer requests to different-2 servers based on IP address and port numbers.īelow is our network server. This will configure a Layer 4 Load Balancing (Transport Layer). This article will help you to setup HAProxy load balancing environment on Ubuntu, Debian and LinuxMint. Our Setup will be in top of the Galera cluster with mysql Galera Cluster and to achieve this you should allow the access permeation in the Galera Cluster server by using the below command, also you have to confirm mysql service is running all the service mysql> GRANT ALL PRIVILEGES ON *.* TO WITH GRANT OPTION Then we need some high availability environment that can easily manage with single server failure. This is not possible with single server setup.

Nowadays maximizing Database up-time is very crucial for heavy traffic DB. HAProxy is a very fast and reliable solution for high availability, load balancing, It supports TCP and HTTP-based applications.
