如何在 MySQL 5.7 服务器上禁用 ssl 插件？

  • 772

MySQL 服务器上新引入的 SSL 连接现在默认安装在 CentOS 6.7 默认代表上。

只需删除证书文件就可以使用 Docs 解决它：

“如果服务器在数据目录中没有找到有效的证书和密钥文件，它会继续执行，但不会启用安全连接。” 参考：http ://dev.mysql.com/doc/refman/5.7/en/secure-connections.html

但我想完全禁用 MySQL 服务器上的 SSL 连接插件，因为我想通过删除我不使用的所有内容来优化 MySQL 服务器的性能，这包括这个插件。

如何在 MySQL 社区服务器上禁用 SSL？

centos mysql
