Aqu*_*ion 6 nginx reverse-proxy nginx-reverse-proxy
我在负载均衡器后面有一个 nginx 服务器,nginx 服务器将请求传递到各种服务,但在本例中是一个运行 apache 的 docker 容器。负载均衡器正确设置了 X-Forwarded-For,但当它到达 docker 容器时,X-Forwarded-For 已设置为 LB IP。
我在 nginx 配置中有这个:
/etc/nginx/conf.d/real_ip.conf
set_real_ip_from {{LB IP}};
real_ip_header X-Real-IP;
real_ip_recursive on;

这是虚拟主机:
server {
listen 443 ssl;
listen [::]:443 ssl;
server_name *.domain domain;
include /etc/nginx/snippets/domain_ssl.conf;
add_header X-Nginx-Debug "hi";
proxy_pass_request_headers on;
location / {
proxy_pass_request_headers on;
proxy_pass http://container-php;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Remote-Addr $remote_addr;
proxy_set_header X-Real-IP $http_x_real_ip;
proxy_set_header X-Header-Test "Hello World - $http_x_forwarded_for";
proxy_set_header X-Forwarded-Proto $scheme;
}
}

但我从容器中得到的是:

string(7) "upgrade"

值得注意的是 X-Real-IP、X-Fowarded-For 似乎没有设置,remote_addr 也没有设置。直接从 nginx 提供的文件已正确设置 x-forwarded-for,因此 LB 正在发送正确的标头。
我是不是漏掉了一步?
我最终以一种可行的方式解决了这个问题,但实际上并没有解决根本问题。据我所知,上游 LB 将“X-Forwarded-For”设置为远程地址,而 nginx 神奇地尝试为反向代理正确设置该设置总是出错,并将其设置为 LB 地址或空地址细绳。
相反,我将 LB->Server 位从 HTTP 切换到 PROXY 协议,在 /etc/nginx/proxy_params 中设置以下内容:
proxy_set_header X-Real-IP $proxy_protocol_addr;
proxy_set_header X-Forwarded-For $proxy_protocol_addr;

在conf.d中:
/etc/nginx/conf.d/real_ip.conf
set_real_ip_from {{ LB_IP }};
real_ip_header proxy_protocol;

现在一切正常了。
