slave to let slave know which position on which binlog of the master node to copy data. Therefore, you need to know the master's ip address, user_name, user_passwd, binlog, binlog_position, and how long it takes to connect to the master. 8. enable slave Mysql> start slave; 9. remove the read-only master restriction and perform tests.Mysql> unlock tables; Mysql> use blog;

If MongoDB is just a document-type database, there is no bright spot, however MongoDB's greatest advantage is read-extended, hot-backup, failback, and Auto-sharding (write extension). This section of the series to the end of the introduction of these features.Backup copy realizes the database backup simultaneously, realizes the reading and writing separation, and realizes the load balance of the read operation, namely one main write server, multiple slave backup and read server, and supports the

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

The data synchronization function of mysql not only provides load balancing for database queries to a certain extent, but also provides great help for database redundancy, backup, recovery, and load balancing. The data synchronization function can be implemented through master-slave replication, while master-slave replication is performed asynchronously.
