試驗環境，MySQL主主復制

主庫10.72.16.112

從庫10.72.16.50

一直有個疑問，利用sql_log_bin=0可以臨時在客戶端停止將操作記入binlog中，如果使用source命令導入批量SQL會有同樣的效果嗎。今天有事就測試了一把

對hch庫的tb1表進行試驗，原數據情況如下，主從數據都是一致的

主庫
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)

從庫
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)

編寫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');

在主庫上做試驗

# 臨時關閉sql_log_bin參數 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)# 執行導入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)

對比主從之間的對比結果

# 主庫查詢執行結果 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 | | 13 | test3 | | 14 | test4 | | 15 | test5 | | 16 | test6 | | 17 | test7 | | 18 | test8 | +----+-------+ 18 rows in set (0.00 sec)# 從庫執行查詢結果 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 (0.11 sec)

結論，可以看出設置sql_log_bin=0，用source命令導入SQL也可以不記入binlog中。
