• 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 | +----+-------+ | 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

    # 主库查询执行结果

    ERROR:

    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。
