MySQL Cluster: use MariaDB-Galera integrated version of MariaDBCentOSMysql cluster under CentOS6 BitsCN.com Speaking of mysql clusters, it is estimated that many people will first think of mysql's built-in replication or mysql-mmm. Mysql-mmm is actually based on the built-in replication of mysql, but the encapsulation is better, but it is still difficult to configure, and it is powerless to dynamically increase or decrease the master node. By chance,

Unlike the standard MySQL server and MySQL cluster, the MYSQL/MARIADB galera cluster has some small differences in boot mode. Galera need to start a node in the cluster as a reference point, the remaining nodes to join the formation of the cluster. This process is called cluster boot. Booting is an initial step that directs the database node as the primary node, and the other nodes synchronize the data as a

Install the MARIADB version of the package with the Galera cluster feature first:Official Document: https://mariadb.com/kb/en/mariadb/getting-started-with-mariadb-galera-cluster/The replication implemented by Galera cluster differs from the traditional way of replicating MySQL, where traditional replication is done by reading the transactions in the binary log of

Galera is a synchronous multi-master cluster for MYSQL/INNODB databases. Some features and benefits of Galera are: Synchronous replication. Multi Master topology. Read/write to any cluster node. Automatic membership control. Data consistency between replica nodes. Read and Write nodes scalability. Distributed transactions and lock tables. The motivation to implement

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-host cluster. It only supports the XTRADB/INNODB storage engine (although there are support for MyISAM experiments-see WSREP_REPLICATE_M

#Galera集群特点 No delay between clusters, synchronous replication. While Master-slave master-slave asynchronous replication, there is a delay. Active-active Multi-master, the cluster internal server is written at the same time, must wait for all the databases in the cluster to complete the data write, the feedback is complete, so there is no data loss situation. The cluster node automatically fails over, and if a single node fails in the

Percona XtraDB Cluster how to install two Cluster nodes on one server I think it makes no sense to run two or more Percona XtraDB Cluster (PXC) nodes on a single physical server, except for educational and testing purposes, however, this method is still useful in this case. The most popular implementation method seems to be server virtualization, such as using stray boxes. However, in the same way, you can
