mysql主从 主库Position不增加

[lly0911]

请教各位大佬，搭建了一套mysql主从，主库中建表，插入数据，主库中Position不增长，导致从库也同步不过去，这是什么情况？忘各位大佬不吝赐教！


mysql> show master status\G

Replicate_Wild_Do_Table:
为空，改下配置文件，设置库

主库的配置以及改了，从库这个参数应该还需要加吗？

主库不加，是你没开 log_bin 吧，看看这个查询的结果是什么
show variables like '%log_bin';

主库肯定开了的，昨天后来把 binlog-do-db这个参数注释掉，重要增加了，然而不明白为什么会这样

mysql> show variables like '%log_bin';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| log_bin | ON |
| sql_log_bin | ON |
+---------------+-------+
2 rows in set (0.01 sec)

那估计是你配置得有问题
这个参数决定那些库要记录 binlog，如果配置错了，那没有配置上的库自然是不记录 binlog 的
如果 所有库都要同步，那通常不设置这个，默认是所有库都要记录的（有需要可以考虑通过设置 Binlog_Ignore_DB 把系统库过滤掉）
一般做主备就不做设置，这样系统库的也过去，这样保持两边完全一样，主库挂了就直接高性用从库就行
