use a binary log and set a unique ID number.On each slave server, you must set a unique ID number in order to connect to the Maste server(optional) Create an independent user to authenticate the primary server and replicate by accessing the binary logBefore you create a data snapshot or start the replication process, you need to log the master server's binary log location. This information is required at late slave startupIf data already exists on th

You need to understand why your replication behavior lags behind, and then learn how to use the correct method to solve the lag problem. MySQL replication is generally considered very effective. after the master server makes changes, the slave server can make the corresponding changes within several seconds. However, if the synchronization between the two is s

In the previous article "mud: learning the principles of mysql database master-slave synchronous replication", we introduced the basic principles of mysql master-slave replication. In this article, we will test the master-slave synchronous replication function of mysql55. No

Mysql replication is asynchronous. Therefore, after receiving a user's request, the result is returned to the user. And store the information in the memory, and then record it into the binary file. This will Mysql replication is asynchronous. Therefore, after receiving a user's request, the result is returned to the us

Limodou in Soundbreak we play live audio and video 24 hours a day, so we cannot make a convincing test of the new replication feature of MySQL. Through the test, we found that we can use this feature to maintain data synchronization with the backup database server. in this way, when the master server is a source author: Michael Tanoviceanu In Soundbreak, we play live audio and video continuously 24 hours

MySQL'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 the primary server during replicati
