MySQL is an open-source relational database system. Replication is a process that replicates data from a MySQL database server (master server) to another server (slave server slave.Configure the master server)1. Edit the database configuration file my. cnf, which is usually in the/etc/directory.1. # vi/etc/my. cnfAdd the following code under [mysqld:1. log-bin =

Semi-synchronous replication in MySQL master-slave Replication Experiment MySQL uses the plug-in provided by Google to complete the semi-synchronous replication model; the physical machine is still Windows 7, and the virtual machine is CentOS 7; Master node: 192.168.255.2 Sl

The master-slave replication structure of MySQL is different from the master-slave replication structure. In the master-master replication structure, any changes to the data inventory on one of the two servers will be synchronized to the other, so that the two servers are mutually master-slave, and can provide external

Tags: User name database server password MySQLWe may encounter this problem when we use the MySQL server database, and if one of the MySQL databases goes down, we want to fix it in the shortest possible time and use the database as quickly as we can, but what if we encounter some failures that cannot be quickly repaired?We can imagine that if this is another database that is identical to this database, the

: Indicates whether semi-synchronous replication is enabled only when the current server is used as the slave database. on indicates that the replication is enabled. Note: For slave, only the "rpl_semi_sync_slave_status" status is available. Other statuses are displayed as the master. Because I have configured the dual-master mode, all master and slave nodes exist. Note: Pay attention to the status of the a

MyIsam is relatively simple to publish, just copy all the files in the library. The procedure of copying Innodb is similar to that of MyIsam, except that the table content in the Innodb Engine no longer exists in the same database directory (MyIsam does this). In the Innodb engine, data files are stored in files such as ibdata1, and operation logs are stored in files such as ib_logfile0, ib_logfile1, and ib_logfile2 by default.Innodb replication and p
