MySQL replication is primarily replicated from the primary master. What is master-slave replication Master-slave replication means that there is a single device to do as the primary server, one or more servers as from the server. No data is written from the server, and the source of the data is the primary server. Th

time, the entire syntax of the SQL statement is recorded during statement-based replication, while row-based replication records the value of now () updated to the database.For example, run the following statement on the master server:Mysql> update user set createtime = now () where sid = 16;If now () returns the value 20:46:35Statement-based replication records

--i/o thread. The I/O thread opens a normal connection on master and then starts Binlog dump process. Binlog dump process reads the event from the binary log of master, and if it has been followed by master, it sleeps and waits for master to produce a new event. The I/O thread writes these events to the relay log.The SQL slave thread handles the final step of the process. The SQL thread reads events from the log, updating the slave data so that it is consistent with the data in master. As long a

from a master server and then parses and applies them to itself. (3) In a simple replication environment, only two mysql-running hosts are required. You can even start two mysqld instances on one physical server host. One works as the master and the other acts as the slave to complete the replication environment. Howe

the mysql service; 4. Run the linux Command to go to mysql and check whether the slave is correctly started. If an exception occurs during startup, ensure that the Server Load balancer instance is started properly; 5. The newly added database is in the master-master replication chain for testing; 5. How to remove a database from an existing Master: 1. modify the

log content from the specified location (or from the beginning of the log) to the designated log file;2. When Master receives a request from an IO thread from Slave, the IO thread that is responsible for the replication reads the log information from the specified log at the specified location based on the requested information and returns the IO thread to the Slave side. In addition to the information contained in the log, the return information inc
