And store the information in the memory, and then record it into the binary file, this will cause the slave server to lag behind the master server, but this is also good, if you have an error operation, in this time, it is OK to back up data from the server immediately, which requires the mysql administrator to grasp.

Label:MySQL master-slave Replication Principle IntroductionFirst, the principle of replicationMySQL replication tracks all changes to the database (updates, deletions, and so on) based on the primary server in the binary log. Each slave server receives a saved update from the primary server that the primary server has logged to the binary log so that the server can perform the same updates to its copy of th

Note that if you do not want to clear the log file, you need to record the log_file and log_pos of the current master, and specify these two parameters or the slav

, therefore, we recommend that you specify log_bin (the relay_log of the slave server has the same problem ). Note: sync_binlog, innodb_flush_log_at_trx_commit, and innodb_support_xa are all set for security purposes and are not required for replication. Then set the slave server configuration file (default:/etc/my. cnf ): [mysqld]server_id = 200log_bin = mysql-binlog_bin_index =

batch read range falls in the red area and the end point falls in the green area. The start and end points of the batch read range are in the green area, but the red area is covered in the middle. The batch read range falls in the red area. In the preceding 5th cases, a transaction is split into three segments for synchronization. Because there is no transaction header or tail mark in the middle segment, the replica program cannot judge it during rea

consider a common markup SQL solution for decoupling from the MySQL configuration. To put it simply, a special mark SQL statement is inserted when the database is synchronized for replication to mark the change from the replication program. The Mark SQL will enter the binlog. When the replication program reads data, i

cannot be modified. You can also disable the write operation from the beginning. You can also set the super_read_only parameter when the server is started and start the group copy plug-in. Once the group is successfully copied, the value of super_read_only is automatically adjusted. In multi-master mode, the super_read_only parameter is not set for all nodes. in single-master mode, super_read_only is set for all nodes except the master node. If, unfo
