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;
