2059 - Authentication plugin 'caching sha2 password' cannot be loaded: X00gg

这个错误通常出现在 MySQL 数据库的版本升级或者安装了新的版本时。它表示 MySQL 无法加载“caching sha2 password”身份验证插件。这是因为在 MySQL 8.0 版本中，它采用了新的加密算法“caching_sha2_password”，取代了以前版本中的“mysql_native_password”。

要解决这个问题，你可以尝试以下两种方法：

1. 更新 MySQL 客户端库版本。你可以下载 MySQL 8.0 版本的客户端库，然后将其替换掉旧版本的客户端库。

2. 修改 MySQL 用户的身份验证方式。你可以在 MySQL 中创建一个新用户，然后将其身份验证方式设置为“mysql_native_password”，这样就可以避免使用“caching_sha2_password”插件。具体方法可以参考 MySQL 官方文档。

2059 - Authentication plugin 'caching sha2 password' cannot be loaded: @X00eg

回答: 错误代码2059表示无法加载认证插件'caching sha2 password'。这是因为Navicat客户端不支持mysql8新的加密方式，而你的数据库版本是8.0.31，导致连接时出现了这个错误。[1][2]解决这个问题的方法是修改mysql的加密方式为原来的mysql_native_password。如果你是通过Docker部署的数据库，可以通过以下步骤进行修改：
1. 进入mysql容器：`docker exec -it mysql /bin/bash`
2. 进入mysql：`mysql -u root -p`
3. 修改加密规则（如果是远程连接，将'localhost'替换为'%'）：`ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '你的数据库密码';`
4. 刷新权限：`FLUSH PRIVILEGES;`[3]这样就可以解决2059错误了。
