MySQL5.6.20上在master主库配置文件/etc/my.cnf里指定数据库同步到slave从库上使用参数binlog-do-db log-slave-updates 注意事项：
一. master主库上binlog-format = MIXED为混合模式时
mysql master主库:/etc/my.cnf 当binlog-format = MIXED 位混合模式时：
1.1配置文件参数：
[root@cacti etc]# egrep "binlog-format|server-id|log-bin|binlog-do-db|log-slave-updates" /etc/my.cnf
binlog-format = MIXED
server-id = 1131053306
log-bin = /data/mysql/binlog/mysql-bin.log
binlog-do-db=ranzhidb
log-slave-updates=11.2登陆主库master,切入到ranzhidb库操作
mysql> use ranzhidb;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

14 rows in set (0.00 sec)同时在master上跨库操作给同步的数据库ranzhidb创建管理用户时，master上创建的用户是不能同步到slave 上的。
但是在master上切入到ranzhidb库，给库ranzhidb创建管理用户后，创建的用户是可以同步到slave 上的
演示：
master上操作：
mysql> use itop;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql>
mysql>
mysql> grant all on ranzhidb.* to txtuser01@'%' identified by 'test#558996';

5 rows in set (0.00 sec)
mysql> txtuser02用户已经同步到slave上了。
二.mysql master主库:/etc/my.cnf 当binlog-format = MIXED 为混合模式
当master主库配置文件/etc/my.cnf：指定binlog-format= row 模式，主要参数如下：
[root@cacti etc]# egrep "binlog-format|server-id|log-bin|binlog-do-db|log-slave-updates" /etc/my.cnf
binlog-format = row
server-id = 1131053306
log-bin = /data/mysql/binlog/mysql-bin.log
binlog-do-db=ranzhidb
log-slave-updates=12.1登陆MySQL主库master上进行跨库操作：
mysql> use itop
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> select database();
+------------+
