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 | +----+-------+ | 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 (0.10 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 | +---------------+-------+ 1 row in set (0.39 sec) root@localhost:mysql.sock [hch]>set sql_log_bin=0; Query OK, 0 rows affected (0.00 sec) root@localhost:mysql.sock [hch]>show variables like "sql_log_bin"; +---------------+-------+ | Variable_name | Value | +---------------+-------+ | sql_log_bin | OFF | +---------------+-------+ 1 row in set (0.00 sec) # 执行导入sql命令 root@localhost:mysql.sock [hch]>source sql.sh; Query OK, 1 row affected (0.08 sec) Query OK, 1 row affected (0.03 sec) Query OK, 1 row affected (0.06 sec) Query OK, 1 row affected (0.00 sec) Query OK, 1 row affected (0.00 sec) Query OK, 1 row affected (0.03 sec)
对比主从之间的对比结果

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。
