MySQL错误2026-SSL连接错误-Ubuntu 20.04 [英] MySQL ERROR 2026 - SSL connection error - Ubuntu 20.04

问题描述

我最近将本地计算机操作系统从Ubuntu 18.04升级到20.04，我在CentOS(AWS)上运行MySQL服务器.每当我尝试连接到MySQL服务器时，升级后都会引发SSL连接错误.

I've recently upgraded my local machine OS from Ubuntu 18.04 to 20.04, I'm running my MySQL-server on CentOS (AWS). Post upgrade whenever I'm trying to connect to MySQL server it is throwing SSL connection error.

$ mysql -u yamcha -h database.yourproject.com -p --port 3309

ERROR 2026 (HY000): SSL connection error: error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol

但是，如果我同时传递-ssl-mode = disabled 选项，则可以远程连接.

But if I pass --ssl-mode=disabled option along with it, I'm able to connect remotely.

$ mysql -u yamcha -h database.yourproject.com -p --port 3309 --ssl-mode=disabled

查询:

1. 如何在不通过-ssl-mode = disabled
的情况下进行连接
2. 如何在Django应用程序中传递此-ssl-mode = disabled 选项，目前，我已按如下所示对其进行了定义，但仍然遇到相同的错误.

1. How to connect without passing --ssl-mode=disabled
2. How to pass this --ssl-mode=disabled option in my Django application, currently I've defined it as shown below, but I'm still getting the same error.

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'yamcha',
        'USER': 'yamcha',
        'PASSWORD': 'xxxxxxxxxxxxxxx',
        'HOST': 'database.yourproject.com',
        'PORT': '3309',
        'OPTIONS': {'ssl': False},
    }

推荐答案

Ubuntu 20已提高了安全级别.我可以连接允许tls 1的唯一方法.

Ubuntu 20 has improved the security level. The only way i could connect whas allowing the tls 1 .

编辑此文件:

/usr/lib/ssl/openssl.cnf

并放在文件的开头:

openssl_conf = default_conf

在该文件的末尾:

[ default_conf ]

ssl_conf = ssl_sect

[ssl_sect]

system_default = ssl_default_sect

[ssl_default_sect]
MinProtocol = TLSv1
CipherString = DEFAULT:@SECLEVEL=1
