ELB nginx-重定向循环

ELB nginx-重定向循环

我在 nginx 后面有一个 nodejs 应用程序(在本地运行良好),其配置如下:

00_elastic_beanstalk_proxy.conf

upstream nodejs {
    server 127.0.0.1:8081;
    keepalive 256;
}

server {
    listen 8080;
    return 301 https://$host$request_uri;

    location / {
        proxy_pass  http://nodejs;
        proxy_set_header   Connection "";
        proxy_http_version 1.1;
        proxy_set_header        Host            $host;
        proxy_set_header        X-Real-IP   $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    gzip on;
    gzip_comp_level 4;
    gzip_types text/html text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascrip$

}

https配置文件

server {
    listen   443;
    server_name  localhost;
    ssl                  on;
    ssl_certificate  /etc/pki/tls/certs/server.crt;
    ssl_certificate_key  /etc/pki/tls/certs/server.key;
    ssl_session_timeout  5m;
    ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers  ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
    ssl_prefer_server_ciphers   on;
    location / {
        proxy_pass  http://nodejs;
        proxy_set_header   Connection "";
        proxy_http_version 1.1;
        proxy_set_header        Host            $host;
        proxy_set_header        X-Real-IP   $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

我接手了某人的工作,但不确定哪部分是由亚马逊 ELB 生成的。

nginx 和 node 应用程序都已启动,我得到了: __url__ 将您重定向过多次。

答案1

负载均衡器正在通过 HTTP 转发请求,从而创建重定向循环。

我通过在重定向周围添加对 $http_x_forwarded_proto 标头的检查来修复此问题:

if ($http_x_forwarded_proto != "https") { 
    return 301 https://$host$request_uri; 
}
