Mysql8.0开始默认采用新的caching_sha2_password的身份验证方式，常规老接口会因此无法连接数据库。
为继续使用老的身份验证方式，需显式指定身份验证方式为 mysql_native_password，如下：
代码语言：txt复制ALTER USER 'ingp_auth'@'%' IDENTIFIED WITH mysql_native_password BY 'password^kAuAaj*Y';
flush privileges;查询目前已有用户的身份验证方式：
代码语言：txt复制mysql> select host,user,plugin,authentication_string from mysql.user;
