Python 连接到rabbitmq SSLError:[SSL:SSLV3警报握手失败]SSLV3警报握手失败（\u SSL.c:1108）

我正在尝试使用SSL连接rabbitmq，端口61613上的加密连接工作得很好，但我无法使用Let's Encrypt连接到加密端口61614

我使用以下代码简单地连接到TLS 61614 rabbitmq stomp：

hostname='rabbitmq.DOMAIN.NAME'
context = ssl.create_default_context(ssl.Purpose.SERVER_AUTH)

with socket.create_connection((hostname, 61614 )) as sock:
    with context.wrap_socket(sock, server_hostname=hostname) as ssock:
        print(ssock.version())

结果：

SSLError: [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:1108)

使用openssl进行测试：

openssl s_client -connect rabbitmq.DOMAIN.NAME:61614

结果是：

有什么建议可以解决吗？

openssl s_客户端的输出显示与Python的输出基本相同的错误：

但这也表明TLS握手的主要部分起了作用，即它获得了证书、密码等，并且还表明服务器似乎要求客户端证书：

Acceptable client certificate CA names
C = US, O = Let's Encrypt, CN = Let's Encrypt Authority X3
CN = ************************
Client Certificate Types: ECDSA sign, RSA sign, DSA sign

但是您的

openssl s_客户机

和Python代码都不提供任何客户机证书。很可能由于缺少客户端证书，服务器最终放弃了TLS握手，从而导致握手失败

---

因此，您需要更改服务器配置，不请求任何客户机证书，或者需要通过提供预期的客户机证书来匹配服务器对客户机证书的要求-无论这是什么（检查您的服务器）。

我刚刚忘了在rabbitmq.conf中添加以下内容：

ssl_options.depth  = 2

现在一切都正确了

谢谢你的帮助

ssl_options.depth  = 2
