环境：

centos6.5

nginx：1.10

openssl:1.0.1e-15

测试样例一：

web访问 https协议的URL https://test.xx.com/demo

nginx 开启证书配置，代理后端非安全协议的url，例如：http://xx.xx.com/xx

server {

listen 443;

server_name test.xxxx.com;

ssl on;

ssl_certificate /etc/nginx/key_file/xxxx.crt;

ssl_certificate_key /etc/nginx/key_file/xxxx.key;

ssl_session_timeout 5m;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;

ssl_session_cache shared:SSL:50m;

ssl_prefer_server_ciphers on;

access_log /var/log/nginx/test.access.log;

error_log /var/log/nginx/test.error.log;

index index.html index.htm index.php index.jsp;

location /demo{

proxy_pass http://x.x.x.x/demo;

proxy_redirect off;

client_max_body_size 8m;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_connect_timeout 60s;

}

前端访问 https://test.xx.com/demo

这种模式在普通的后端server可以正常访问页面（数据转发之类的），但在负责多样式的页面调试会出现相关样式调用错误。

测试样例二：

web访问 https协议的URL https://test.xx.com/demo

nginx 开启证书配置，代理后端安全协议的url，例如：https://xx.xx.com/xx

server {

listen 443;

server_name test.xxxx.com;

ssl on;

ssl_certificate /etc/nginx/key_file/xxxx.crt;

ssl_certificate_key /etc/nginx/key_file/xxxx.key;

ssl_session_timeout 5m;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;

ssl_session_cache shared:SSL:50m;

ssl_prefer_server_ciphers on;

access_log /var/log/nginx/test.access.log;

error_log /var/log/nginx/test.error.log;

index index.html index.htm index.php index.jsp;

location /demo{

proxy_pass https://x.x.x.x/demo;

proxy_redirect off;

client_max_body_size 8m;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_connect_timeout 60s;

}

这种模式比较消耗后端性能。

此时：后端server https://172.10.18.34:8443/mpweb访问正常，

前端访问 https://test.xxxx.com/demo报502 错误，查访问日志

在代理与后端server之间的ssl协议会话的时候，出现一下错误：

[error] 7957#7957: *720292 SSL_do_handshake() failed (SSL: error:100AE081:elliptic curve routines:EC_GROUP_new_by_curve_name:unknown group error:1408D010:SSL routines:SSL3_GET_KEY_EXCHANGE:EC lib) while SSL handshaking to upstream, client: x.x.x.x, server: test.huiepay.com, request: "GET /favicon.ico HTTP/1.1", upstream: "https://172.10.18.34:8443/favicon.ico", host: "test.xxxx.com", referrer: "https://test.xxxx.com/mpweb"

通过测试样例一可以得出，排除后端server问题，依然是代理错误。

通过elliptic curve routines:EC_GROUP_new_by_curve_name:unknown group”根据这个报错信息判断是的可以判断出： openssl什么版本
