 本人遇到的错误总结

错误1 Can't connect to Mysql server on....(10060)

是因为没有开放远程端口  参考 https://www.cnblogs.com/wintest/p/11442920.html 

或 https://blog.csdn.net/wrs120/article/details/78771468

错误2 1251-Client does not support authentication protocol requested by server

是因为插件问题，参考这篇文章：https://my.oschina.net/u/3295928/blog/1811804
