The difference between reset slave and reset Master The syntax for RESET slave is as follows: RESET SLAVE [All] [channel_option] Channel_option:For CHANNEL CHANNELAmong them, Channel_option is mainly aimed at multi-source replication introduced by 5.7.6. RESET SLAVE The official explanation is as follows RESET SLAVE makes the SLAVE forget its replication position in the master ' s binary log. This sta

MySQL Master-Slave replication (Master-slave) practice, mysqlmaster-Slave The master-slave replication function provided by the MySQL database can easily implement multiple automatic data backups and expand the database. Multiple data backups not only enhance data security, but also further improve database load performance by implementing read/write splitting. T

Some time ago, the company's projects were too busy to write a blog. Today, I want to write an article. I have explained the basic operations of apsaradb for redis in the previous section. Now I will continue to explain the advanced sections of apsaradb for redis, including master-slave replication and read/write splitting. 1. What is Master slave? This is what we call

code) master Page . a master page is a feature of ASP.net that is specifically designed to standardize Web page layouts . It defines fixed content and declares parts of a Web page that can be inserted into custom content. If you use the same master page throughout your site, you can make sure you get the same layout. Best of all, if you modify the definition of

Mysql master-slave replication, mysql master-slave Master-slave replication: There are two ways to start master-slave replication from MySQL5.6: Log-based (binlog); GTID-based (global transaction identifier ); 1. Log-based master-slave replication principle: Mysql Replicatio

1. In the primary database server, add a user with access to the main library from the server: GRANT REPLICATION SLAVE on *.* to ' test ' @ '% ' identified by ' test '; (% to allow all IP, can set specified from server IP) After adding a user: Mysql-h127.0.0.1-utest-ptest can be used on the server; To test whether you have access to the primary database 2. In the main repository configuration file plus:#master ConfigServer-id = 1Log-bin = Mysql-bi

Why is there a master-master replication of mysql. In some highly available environments, mysql Master/Slave cannot meet some practical needs. For example, if there is a bottleneck for access to some websites with high traffic, two or more mysql servers will be used for load balancing, and the database data of these mysql servers must be consistent,

MySQL ReplicationMySQL replication refers to the transfer of DDL and DML operations on the main library to the library from the binary log, keeping the master and the data from the library in syncMySQL Master-slave Architecture: Advantages: Can cut the library when failure, read and write separation, perform other business from the library such as backup.1:master

MySQL replication is a master-slave synchronization solution for multiple MySQL databases. It features Asynchronization and is widely used in various scenarios that require higher performance and reliability for MySQL. Another technique corresponding to this is the synchronized MySQL cluster, but because of its complexity, there are fewer users.MySQL officially provides the scenario for using replication: Replication principles MySQL replication
