错误 002061 - 身份验证插件“caching_sha2_password”报告错误：身份验证需要安全连接

Question

RDS 上的 MySQL 版本 - 8.0.23 我正在将本地数据库复制到 AWS RDS MySQL 实例。但我收到此错误：

2021-11-11T22:43:09.091947Z 378 [ERROR] [MY-010584] [Repl] Slave I/O for channel '': error connecting to master 'replicator@localhost:3306' - retry-time: 60 retries: 1 message: Authentication plugin 'caching_sha2_password' reported error: Authentication requires secure connection.

我尝试将主数据库用户密码格式更改为 mysql 本机密码。但这没有帮助。我该怎么做才能解决这个问题？

Answer 1

请使用 GET_MASTER_PUBLIC_KEY=1 运行更改主命令

Answer 2

在mysql复制数据库中做了主/从。我也有一个错误，我暂时忽略了，就像这样

CHANGE MASTER TO GET_MASTER_PUBLIC_KEY=1;

Answer 3

自 MySQL 服务器 8.0.11 起

缓存_sha2_密码

用作默认身份验证方法。不过，您可以使用该插件

mysql_native_password

使用旧方法登录。

Answer 4

如其他答案中所写，使用

GET_MASTER_PUBLIC_KEY=1

。
完整的连接字符串是：

CHANGE REPLICATION SOURCE TO
SOURCE_HOST='master_ip_number',
SOURCE_USER='replica_user',
SOURCE_PASSWORD='p4zzw0rd',
SOURCE_LOG_FILE='binlog.000007',
SOURCE_LOG_POS=7777,
GET_MASTER_PUBLIC_KEY=1;

您将从大师处通过以下命令获得

SOURCE_LOG_FILE

和

SOURCE_LOG_POS

：

SHOW MASTER STATUS;

Answer 5

原因：caching_sha2_password必须使用ssl模式，但{--ssl-mode}禁用ssl模式。

解决：将 {--ssl-mode} 从 {DISABLED} 更改为 {REQUIRED} mysql -hsqlip --ssl-mode=必需-utest -p123
