解决方法：

根据上述的主从同步信息，

Relay_Log_File: mysql-relay-bin.000486
Relay_Log_Pos: 212230586

在从库上使用mysqlbinlog将日志文件解析出来，命令如下：

mysqlbinlog  --no-defaults -v -v --base64-output=DECODE-ROWS mysql-relay-bin.000486 > /tmp/mysql-relay-bin.000486

在解析出来的文件中找到对应的POS点: 212230586

发现在执行 revoke语句 删除用户权限。

查看从库上的用户库，发现没有用户 f_common。 所以就出现问题了。

问题原因已经清楚了，后续就自己处理了。
