MySQL用source命令导入不记入binlog中【原创】

试验环境，MySQL主主复制

主库10.72.16.112

从库10.72.16.50

一直有个疑问，利用sql_log_bin=0可以临时在客户端停止将操作记入binlog中，如果使用source命令导入批量SQL会有同样的效果吗。今天有事就测试了一把

对hch库的tb1表进行试验，原数据情况如下，主从数据都是一致的

主库
root@localhost:mysql.sock [hch]>select * from tb1;

+----+-------+

| id | cname |

+----+-------+

|   | php   |

|   | java  |

|   | go    |

|   | test  |

|   | test1 |

|   | test2 |

|   | test3 |

|   | test4 |

|   | test5 |

|  | test6 |

|  | test7 |

|  | test8 |

+----+-------+

 rows in set (0.10 sec)

从库
mysql> select * from hch.tb1;
+----+-------+
| id | cname |
+----+-------+
|  1 | php   |
|  2 | java  |
|  3 | go    |
|  4 | test  |
|  5 | test1 |
|  6 | test2 |
|  7 | test3 |
|  8 | test4 |
|  9 | test5 |
| 10 | test6 |
| 11 | test7 |
| 12 | test8 |
+----+-------+
12 rows in set (0.01 sec)

编写sql文件

insert into tb1(cname) values('test3');

insert into tb1(cname) values('test4');

insert into tb1(cname) values('test5');

insert into tb1(cname) values('test6');

insert into tb1(cname) values('test7');

insert into tb1(cname) values('test8');

在主库上做试验

# 临时关闭sql_log_bin参数

root@localhost:mysql.sock [hch]>show variables like "sql_log_bin";

+---------------+-------+

| Variable_name | Value |

+---------------+-------+

| sql_log_bin   | ON    |

+---------------+-------+

 row in set (0.39 sec)

root@localhost:mysql.sock [hch]>set sql_log_bin=;

Query OK,  rows affected (0.00 sec)

root@localhost:mysql.sock [hch]>show variables like "sql_log_bin";

+---------------+-------+

| Variable_name | Value |

+---------------+-------+

| sql_log_bin   | OFF   |

+---------------+-------+

 row in set (0.00 sec)

# 执行导入sql命令

root@localhost:mysql.sock [hch]>source sql.sh;

Query OK,  row affected (0.08 sec)

Query OK,  row affected (0.03 sec)

Query OK,  row affected (0.06 sec)

Query OK,  row affected (0.00 sec)

Query OK,  row affected (0.00 sec)

Query OK,  row affected (0.03 sec)

# 主库查询执行结果

结论，可以看出设置sql_log_bin=0，用source命令导入SQL也可以不记入binlog中。
