1.MySQL High-availability backgroundsThe master-slave replication of a database is a useful feature, but it is difficult to ensure its high availability. Implements MySQL master-slave replication high-availability tools, common are:

1. IntroductionAs one of the most widely used databases in the world, MySQL is one of the reasons why it is free. But what is not to be overlooked is that its own function is indeed very powerful. With the development of technology, in the actual production environment, the single MySQL database server can not meet the actual demand. At this point the database cluster is a good solution to this problem. Wit

Set add New item do not initialize entire snapshotThe publisher often creates new tables or other database objects, such as stored procedures or functions, that you need to initialize if you want to add these new items to an existing subscription. But the default setting is to initialize all items of the entire snapshot. This is expensive for large snapshots.The following setting

Sometimes we need to copy the table structure of a table intact to generate a new table. MYSQL provides two convenient methods.

The MySQL BINLOG and show processlist commands were originally two transactions that could not be reached by the client. However, in the recent troubleshooting, it was found that there was a serious
IntroductionGtid is a global transaction ID that has been successfully executed based on the original MySQL server, combined with the server ID and transaction ID. This global transaction ID is unique not only on the original server, but also on all MySQL servers where the master-slave relationship exists. It is this feature that makes MySQL master-slave

First, IntroductionIn the master-slave copy of the previous article: http://www.cnblogs.com/lay2017/p/9043985.htmlWe learned that MySQL writes logs through master, slave reads and executes the log content to achieve slave data consistent with master. So based on this principle, we can realize the replication function of two master.Broadly as follows:1, both master open Log-bin write log2, ID to repeat3. Con

Data from one master library can be synchronized to multiple repositories, and the repository itself can be configured as the main repository for other servers.Main applications:1) Data distribution2) Load Balancing3) Pseudo backup. Add more secure technical supplements based on backup4) High availability and failover. Avoid MySQL single point of failure5) Upgrade test. Before upgrading
Label:1 Replication OverviewMySQL's built-in replication capabilities are the foundation for building large, high-performance applications. The distribution of MySQL data across multiple systems is done by copying data from one of the MySQL hosts to the other host (slaves) and re-executing it again. One server acts as
