3. Configure master-Slave synchronization:

#在MDB上执行

Mysql-uxxx-pxxx-h127.0.0.1-e "Show master status \g;"

View current Binlog values and POS values

For example:

#在SDB上执行

mysql-uxxx-pxxx-h127.0.0.1

>slave stop;

>change Master to master_log_file= ' mysql-bin.000001 ', master_log_pos=582783685;

Prompt to execute after OK

>slave start

See if syncing

>show slave status \g;
