MariaDB, as a branch of Mysql, is already widely used in open source projects, such as hot OpenStack, so the cluster deployment is essential to ensure high availability of the service while increasing the load capacity of the system.MariaDB Galera Cluster IntroductionThe MariaDB cluster is a MariaDB synchronous multi-h

High MySQL Availability Based on MHA and Galera Cluster MHA: Master HA is an open-source MySQL high-availability program. It provides the automatic master failover function for the MySQL Master-slave replication architecture. When MHA detects a master node failure, it will escalate the slave node with the latest data to the new master node. During this period, MHA will obtain additional information on the s
