我按规矩设置了主服务器和从服务器。我LOAD DATA FROM MASTER;在从服务器上运行了初始程序，运行正常。但是当我将数据插入主服务器时，数据根本没有复制到从服务器上。我已经尝试重新启动主服务器和从服务器的 mysqld 进程，并在从服务器上执行“从服务器停止/从服务器启动”。发生了什么？

有人知道哪里可能出错了吗？用户“复制”具有完全权限（在主服务器和从服务器上都运行了该权限）；
grant replication slave on *.* to replication@'%' identified by 'hidden';
GRANT ALL PRIVILEGES ON pchelp.* TO replication;
再次，LOAD DATA FROM MASTER;命令运行正常..我不明白。
答案1
或者binlog_do_db可能binlog_ignore_db不会按照您想象的方式工作。 以下是 Baron Schwarz 解释的原因。我的猜测是，在编写该命令之前，您要么写了 ，USE mysql要么写了USE test。由于这两个数据库被忽略，因此您在使用该数据库时运行的任何语句（即使它们写入另一个数据库）都将被忽略。
主服务器甚至没有将该INSERT语句写入二进制日志的一个提示来自SHOW MASTER STATUS\G命令的输出。语句之前和之后均有提示INSERT：
Position: 106
从属设备也具有相同的立场，这解释了为什么它认为自己工作正常：
Read_Master_Log_Pos: 106
建议：删除binlog_do_db和binlog_ignore_db配置选项。如果需要过滤，请在从属服务器上执行。
