16.1.1.10. Setting the Master Configuration on the Slave

To set up the slave to communicate with the master for replication, you must tell the slave the necessary connection information. To do this, execute the following statement on the slave, replacing the option values with the actual values relevant to your system: 

mysql> CHANGE MASTER TO
    ->     MASTER_HOST='master_host_name',
    ->     MASTER_USER='replication_user_name',
    ->     MASTER_PASSWORD='replication_password',
    ->     MASTER_LOG_FILE='recorded_log_file_name',
    ->     MASTER_LOG_POS=recorded_log_position;

Note

Replication cannot use Unix socket files. You must be able to connect to the master MySQL server using TCP/IP.

The following table shows the maximum allowable length for the string-valued options.

Option Maximum Length
MASTER_HOST 60
MASTER_USER 16
MASTER_PASSWORD 32
MASTER_LOG_FILE 255
