今天在测试使用sqlyog或者navicat 去 连接MySQL8.0 的时候，出现如下报错提示：

ERROR 2059 (HY000): Authentication plugin 'caching_sha2_password' cannot be loaded: ÕÒ²»µ½Ö¸¶¨µÄÄ£¿é¡£

看样子是验证插件问题的，排查下:

代码语言：javascript复制
SELECT `user`, `host`, `authentication_string`, `plugin` FROM mysql.user;
 ------------------ ----------- ------------------------------------------------------------------------ ----------------------- 
| user             | host      | authentication_string                                                  | plugin                |
 ------------------ ----------- ------------------------------------------------------------------------ ----------------------- 
| archiver         | %         | $A$005$==t@l=SP'G{U[1})D8yLwA6ti2uHtmUKNuHxQSUggrBRMBR2CheCw0Oxad9 | caching_sha2_password |
| mysql.infoschema | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE                              | mysql_native_password |

 ------------------ ----------- ------------------------------------------------------------------------ -----------------------

修改arhiver账号的密码验证插件类型：

代码语言：javascript复制
ALTER USER 'archiver'@'%' IDENTIFIED WITH mysql_native_password BY 'archiver';

flush privileges;

再次看下，

代码语言：javascript复制
SELECT `user`, `host`, `authentication_string`, `plugin` FROM mysql.user;
 ------------------ ----------- ------------------------------------------------------------------------ ----------------------- 
| user             | host      | authentication_string                                                  | plugin                |
 ------------------ ----------- ------------------------------------------------------------------------ ----------------------- 
| archiver         | %         | *13D295FD7B8108ABBC89FCDDD342FFBFF5DA803C                              | mysql_native_password |
| mysql.infoschema | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE                              | mysql_native_password |
| mysql.session    | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE                              | mysql_native_password |

 ------------------ ----------- ------------------------------------------------------------------------ -----------------------

我们再用sqlyog 连接，发现是可以使用了。。

flush plugin privileges rows set
