我有一台配备OpenSSl 1.0.2j的centos 7服务器。 Nginx正在使用HTTP / 2,但haproxy失败。
当我尝试运行卷曲(已经是版本7.51)一旦启用alpn h2我有以下错误:
curl --http2 -I https://domain:port/file.htm
curl: (16) Error in the HTTP2 framing layer
如果我禁用了h2,curl工作正常但当然只连接http 1.1:
curl --http2 -I https://domain.com:port/file.htm
HTTP/1.1 200 OK
Server: nginx/1.11.6

这里我放了haproxy设置(假设只设置为https模式)

另外我看到另一个网站告诉haproxy不支持Http / 2.
https://istlsfastyet.com/#server-performance
有什么问题? Haproxy?
Centos 7 openssl支持?
感谢您的阅读。帮助世界为http / 2准备haproxy。
我想添加另一个相关的问题。
“在Web服务器上设置haproxy时,haproxy将进行ALPN协商”。
如果我们可以在两个级别和不同的服务器中使用haproxy会发生什么。
Server 01 - Level 01 - Haproxy ( listen ssl)
Server 02 - Level 02 - Haproxy ( listen ssl)
Server 03 - Level 03 - Nginx ( listen no ssl )
在这个模型中,谁做过Alpn谈判?
在我的测试中,我试图从SSL创建代理到另一个SSL服务器。
谢谢大家。
Brqx / Ricardo。
答案 0 :(得分:3)
在Web服务器上预先设置haproxy时,haproxy将进行ALPN协商。这意味着只有haproxy知道协商了哪个协议(http/1.1
或h2
)。我相信你看到一个错误,因为haproxy正在协商h2
,然后将明文HTTP / 2流量发送到不期望它的服务器。
正如您所希望的“The complete guide to HTTP/2 with HAProxy and Nginx”网站所指出的那样,您解决的问题是您为两个端口列出了Nginx:一个用于HTTP / 1.1,另一个用于HTTP / 2:
listen 80 default_server;
listen 81 default_server http2 proxy_protocol; ## Needed when behind HAProxy with SSL termination + HTTP/2 support
然后,在haproxy中,您声明两个后端:
backend nodes-http
server node1 web.server:80 check
backend nodes-http2
mode tcp
server node1 web.server:81 check send-proxy
并根据协商的ALPN协议指示流量:
use_backend nodes-http2 if { ssl_fc_alpn -i h2 }
