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!

为空,改下配置文件,设置库
show variables like '%log_bin';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| log_bin | ON |
| sql_log_bin | ON |
+---------------+-------+
2 rows in set (0.01 sec)
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
