How to change Group Replication Mode in MySQL In this blog, we will see How to change the mode in which a group is running in, either single or multi-primary. For this we will use two functions group_replication_switch_to_multi_primary_mode() & group_replication_switch_to_single_primary_mode(). These functions used to change a group’s mode can be run on any member. In
Deploying MySql Group Replication in Single-Primary Mode Group Replication is provided as a plugin to MySQL Server. MySQL Group Replication enables you to create elastic, highly-available, fault-tolerant replication topologies and Group Replication guarantees that the database service is continuously available. Groups can operate in a single-primary mode with the automatic primary election, where only one
How To Bootstrap MySQL Router For InnoDB ReplicaSet In the previous blog, we saw How to Configure InnoDB ReplicaSet Click here to read more & How to perform Switchover/Failover in MySql InnoDB ReplicaSet Click here to read more. We will use the same configuration to install and bootstrap mysql router. Bootstrap MySQL Router against an InnoDB ReplicaSet
How to perform Switchover/Failover in MySql InnoDB ReplicaSet In the previous blog, we saw Part I: How to Configure InnoDB ReplicaSet MySQL Click here to read more. We will use the same configuration to perform Switchover & Failover in InnoDB ReplicaSet. Below are the setup information. Hostname IP Role Server_ID Port Installation Link test-machine01 192.168.114.177
How to Configure InnoDB ReplicaSet mysqlshell AdminAPI includes support for InnoDB ReplicaSet, which enables you to create and administer a set of MySQL instances running asynchronous GTID-based replication. An InnoDB ReplicaSet consists of a single primary and multiple replicas. InnoDB ReplicaSet Prerequisites Only instances running MySQL version 8.0 and later are supported. Only GTID-based replication is supported, binary log file
Asynchronous Replication Automatic Failover in MySQL MySQL 8.0.22 supports an asynchronous connection failover mechanism. This feature allows a replica/slave to automatically failover to a new source/master, in case its existing source/master fails. When the existing connection source/master fails, the replica first retries the same connection for the number of times specified by the MASTER_RETRY_COUNT. The
How to Setup MySQL Master-Master Replication (Circular Replication) Master-Master Replication (Circular Replication) also known as ring topology in MySQL, this setup requires two or more MySQL servers which act as a master. All masters receive writes and generate binlogs. Below points should be considered while doing the master-master setup. You need to set an auto-increment
MySQL Multi-Source Replication – GTID Based Sources In this blog post, we will see How to setup MySQL Multi-Source Replication – GTID Based Sources. For this demonstration, we will be using the below configuration. We have already set up 2 mysql instance in test-machine01 server running on port 3306 (Server_ID : 1) & 3307 (Server_ID
Create MySQL Instance Replica using Clone Command MySQL 8 has recently released clone plugin which makes cloning process very easy and handy to perform. In this blog we will see How to install and perform clone of mysql instance. I will clone complete mysql instance server_id 3 into server_id 4, Please note in server_id 4
MySql Semisynchronous Replication In the previous blog, we saw How to create MySql GTID-based Master Slave Replication – Single DB, Click here to read more. We will use the same configuration to convert it from asynchronous to semisynchronous. MySQL replication by default is asynchronous. MySQL 8.0 supports an interface to semisynchronous replication that is implemented by plugins. Step 1.
