test mysql replication

First, Mysql 5.6 new features....Improvements to replication features⒈ supports multi-threaded replication, (slave-parallel-workers=0 0: Disables multithreading;) it actually turns on the corresponding independent thread for each database. That is, each library has a separate (SQL thread), if the online business, only one database or most of the pressure on the i

If both Slave_IO_Running and Slave_ SQL _Running are yes, the configuration is successful. Test Create a database on

The master server transfers the data to the slave server for hot backup or warm backup, or stop the service for cold backup when backup is required. 4) provides high availability and Failover functions to ensure that the s

Master-slave replication for mysql and master-slave replication for mysql Perform the following steps for master-slave replication: Assume that the two master-slave mysql servers are deployed on the same machine on different ports

Tagged: Server server multithreading MySQL styleGtid,global Transaction Identifiers, the global transaction identifier consists of a unique identifier for the server's UUID and transaction ID number. After MySQL 5.6, the transaction header records the server UUID, which is very simple to track.Uuiduniversally unique Identifier, globally unique identifier. A is master,b, C is slave, and when a goes down, B

Asynchronous replication: MySQL natively supports one-way, asynchronous replication. Asynchronous replication means there is a delay in copying data from one machine to another-most importantly this means that the data cannot be copied/applied to the slave at the same time when the application's transaction commit has

. The slave server needs to configure the security function on mysql5.6, which means the information is usually contained on the master server. Information or logs should be in a table. Let's get started with configuration. Here is an example! First, you need to download the mysql test version. Click this link to download. We need a sandbox environment for the slave server and two master servers. I will not
