MySQL8.0提示 caching_sha2_passwor‘ cannot be loaded

ERROR 2059 (HY000): Authentication plugin 'caching_sha2_password' cannot be loaded: ?ò2?μ????¨μ??￡?é?￡

看样子是验证插件问题的，排查下:

SELECT `user`, `host`, `authentication_string`, `plugin` FROM mysql.user;

+------------------+-----------+------------------------------------------------------------------------+-----------------------+

修改arhiver账号的密码验证插件类型：

ALTER USER 'archiver'@'%' IDENTIFIED WITH mysql_native_password BY 'archiver';

flush privileges;

再次看下，

SELECT `user`, `host`, `authentication_string`, `plugin` FROM mysql.user;

+------------------+-----------+------------------------------------------------------------------------+-----------------------+

| user             | host      | authentication_string                                                  | plugin                |
