MySQL5.6參數binlog-do-db和log-slave-updates跨庫同步註意事項

fec oca 6.2 warnings 混合 urn 1-1 esc master

MySQL5.6.20上在master主庫配置文件/etc/my.cnf裏指定數據庫同步到slave從庫上使用參數binlog-do-db log-slave-updates 註意事項：

一. master主庫上binlog-format = MIXED為混合模式時

mysql master主庫:/etc/my.cnf 當binlog-format = MIXED 位混合模式時：
1.1配置文件參數：

[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=1

1.2登陸主庫master,切入到ranzhidb庫操作

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
Database changed
mysql> insert into droa_attend (id,account,date,status) values (‘14‘,‘yuyu‘,‘2018-01-20‘,‘rest‘);
Query OK, 1 row affected, 10 warnings (0.00 sec)
mysql> select * from  droa_attend ;

同步成功

1.4登陸master主庫進行跨庫操作
但是登陸master主庫進行跨庫操作的時候,在master主庫ranzhidb.droa_attend表裏面插入一條記錄，但是在master上插入的記錄沒有同步到slave上

同時在master上跨庫操作給同步的數據庫ranzhidb創建管理用戶時，master上創建的用戶是不能同步到slave 上的。
但是在master上切入到ranzhidb庫，給庫ranzhidb創建管理用戶後，創建的用戶是可以同步到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‘;
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

slave上操作：

mysql> select user,host from mysql.user;
+------------+-----------+
| user       | host      |
+------------+-----------+
| testuser03 | %         |
| testuser04 | %         |
| root       | 127.0.0.1 |
| root       | localhost |
+------------+-----------+
4 rows in set (0.00 sec)

txtuser01用戶沒有同步過來

master上操作：

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
Database changed
mysql> grant all on ranzhidb.* to txtuser02@‘%‘ identified by ‘test#558996‘;

mysql> flush privileges;

txtuser02用戶已經同步到slave上了。

二.mysql master主庫:/etc/my.cnf 當binlog-format = MIXED 為混合模式

當master主庫配置文件/etc/my.cnf：指定binlog-format= row 模式，主要參數如下：

[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=1

2.1登陸MySQL主庫master上進行跨庫操作：

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();
+------------+
| database() |
+------------+
| itop       |
+------------+
1 row in set (0.00 sec)

mysql> insert into ranzhidb.droa_attend (id,account,date,status) values (‘15‘,‘fangfang‘,‘2018-01-18‘,‘rest‘);
Query OK, 1 row affected, 10 warnings (0.00 sec)

2.2但是此時在master上跨庫給同步的數據庫ranzhidb創建授權用戶時，授權用戶是沒有同步到slave上的。
master上操作：

+------------+
1 row in set (0.00 sec)
mysql> grant all on ranzhidb.* to ‘testuser02‘@‘%‘ identified by ‘test#558996‘;
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

slave上查看：

mysql> select user,host from mysql.user;
+------+-----------+
| user | host      |
+------+-----------+
| root | 127.0.0.1 |
| root | localhost |
+------+-----------+
2 rows in set (0.00 sec)

主庫上創建的用戶testuser02沒有同步到slave 上

2.3在master上切換到同步數據庫ranzhidb,創建授權用戶

mysql> use ranzhidb;

You can turn off this feature to get a quicker startup with -A

Database changed
