During mysql Master-Slave synchronization, the Master database and Slave database may not be synchronized for various reasons, although there are some solutions on the Internet, it is sometimes difficult to completely solve the problem. Resetting the Master/Slave server may not be the fastest way, but it is the most secure and effective. Under www.2cto.com, We will summarize the steps for resetting the master-slave synchronization to meet your needs.M
MySQL table column replication, MySQL connection time and memory control. There are two table temporary table temp_t, and the positive table table1, are MyISAM, respectively, there are about 28W records. Cron periodically fetches some information from the network every minute and stores it to temp_t (frequent writes). Then cron timed every 10 minutes to copy info
MySQL replication advantages and principles Replication transfers the DDL and DML operations of the primary database to the slave database through binary logs, and rewrites the data from the slave database to ensure data synchronization between the slave database and the primary database. MySQL can replicate data from
Tags: server database binary SQL statement master What is master-slave replication:By copying data from one of the MySQL hosts to a different host, one server acts as the primary server (master) while one or more other servers act as slave servers (slave). When replicating, all writes to the data table must be performed on the primary server. Otherwise, because the primary server does not synchronize data from the server, it can cause master-slave

MySQL master-slave replication is widely used in database backup, failover, data analysis and other occasions.MySQL master-slave replication keeps track of all changes to the database (update, delete, and so on) in the binary log based on the master server. Therefore, to replicate, you must enable binary logging on the primary server. Receive updates from the ser
