MetaBase Mysql8.0连接不上

• MySQL 8 默认使用 caching_sha2_password 认证方式

• 查询用户认证方式， caching_sha2_password 、mysql_native_password

SELECT user, host, plugin FROM mysql.user

• 修改认证方式

ALTER USER 'your_db_user'@'%' IDENTIFIED WITH mysql_native_password BY 'your_db_password';

FLUSH PRIVILEGES;

sudo systemctl restart mysql

• 或新建用户解决

CREATE USER 'metabase_user'@'%' IDENTIFIED WITH mysql_native_password BY 'your_password';
GRANT ALL PRIVILEGES ON your_database_name.* TO 'metabase_user'@'%';
FLUSH PRIVILEGES;

• 最后，在jdbc连接串种加入 ssl-mode=DISABLED
