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

??? In actual production and development, if multiple nodes coexist, You need to select the master node and implement HA automatic fault tolerance. I have thought about the writing method and shared it with you. The Lease protocol and MysqlACID High Availability primary selection solution are designed. Applicable scenarios: Java language implementation description further optimized ??? The system has many application scenarios similar to the

); (2) Use a Server Load balancer instance as the slave master and only copy the slave database; (3) Use a remote slave for disaster recovery; It should be clear that multiple Slave nodes can be copied from a Master node. Some may wonder if the Slave node can be copied from multiple Master nodes? At least for the time

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,

"commit"), the updates need to be retrieved locally, using the git fetch command. > The above command retrieves the updates for a remote host locally.git fetchCommands are often used to view other people's processes because the code they retrieve does not affect your local development code.By default, git fetch all branches (branch) are retrieved for updates. If you want to retrieve only updates for a particular branch, you can specify
