mysql multi master replication

library to be used as a synchronous backup of offsite data. Starting with the 5.7 version of MySQL to support multi-source master-slave replication (multi-source Replication) is to send multiple d

MySQL replication is primarily replicated from the primary master. What is master-slave replication Master-slave replication means that there is a single device to do as the primary s

course, the use of improper words will be problematic, first to match two instances read and write objects are not cross. (The only synchronized table), followed by the selection of the appropriate storage engine, myism than InnoDB theoretically more suitable for this application. Using the process again for the two mysqld instances on slave, use only one of the native other library tables (non-synchronous) write operations. OK, this solution has passed the test.

The ultimate goal of data replication is to synchronize the data of one server with the data of another server, which can achieve data redundancy or load balancing of services. A master server can connect multiple slave servers, and the slave server can act as the master server in turn. The master-slave server can be l
