mysql 错误 2026 RHEL 6

Question

我在 RHEL6 上将 mysql 升级到 5.7.21。我创建了我的自签名证书并在 my.cnf 中添加了正确的路径，但是，现在我在尝试连接时收到 ERROR 2026通常情况下。只有当我明确指定 SSL_DISABLED 时，我才能连接。我已 双重检查密钥文件中是否出现 RSA。相关文件是：

[root@my-DB1 log]# mysql -u myuser -p
Enter password:
ERROR 2026 (HY000): SSL connection error: SSL is required but the server doesn't                                                                                         support it

知道我错过了什么吗？

Answer 1

重新生成证书，同时记住所有 3 个证书的 CN 应该不同。更改了新生成证书的所有权以匹配 mysql:mysql 。重新启动 mysql，此错误消失。
