主库运行show master status可以看到当前二进制日志的信息,如:
-
mysql> show master status \G
-
*************************** 1. row ***************************
-
File: mysql-bin-3306.000009
-
Position: 35946018
-
Binlog_Do_DB:
-
Binlog_Ignore_DB:
-
Executed_Gtid_Set:
Binlog_Do_DB:由数据库参数binlog_do_db列出的数据库填充。
Binlog_Ignore_DB:由数据库参数binlog_ignore_db填充,如果以上任何配置中都不存在值,那么所有数据库中的写入活动都会被列入二进制日志中。
Executed_Gtid_Set:是MySQL5.6.6的新特性,显示在主库上执行全局事务标识符
在从库上执行show slave status
-
mysql> show slave status \G
