代理后的Nginx：避免自动重定向到内部端口

我有一个设置，其中haproxy在example.com:80上侦听，并将HTTP请求代理给在服务器20080上侦听的nginx实例

nginx所做的只是从

/usr/share/nginx/html

提供静态文件

例如，

http://example.com/doc/

映射到

/usr/share/nginx/html/doc/

但是，

http://example.com/doc

（不带尾随斜杠）导致301重定向到

http://example.com:20080/doc/

：

$ curl -i http://example.com/doc
HTTP/1.1 301 Moved Permanently
Server: nginx/1.0.15
Date: Tue, 09 Dec 2014 15:10:44 GMT
Content-Type: text/html
Content-Length: 185
Location: http://example.com:20080/doc/

请注意，nginx在URL中包含了端口20080。但是，这是不需要的，因为该站点面向公众的URL是

http://example.com/

因此重定向应该是

http://example.com/doc/

向nginx解释这一点最简单的方法是什么

/etc/nginx/nginx.conf

：

user              nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
    access_log  /var/log/nginx/access.log  main;
    sendfile        on;
    keepalive_timeout  65;
    include /etc/nginx/conf.d/*.conf;
}

server {
    listen       20080 default_server;
    include /etc/nginx/default.d/*.conf;

    root /usr/share/nginx/html;
    index index.html;

    location /doc/ {
        auth_basic "Restricted";
        auth_basic_user_file /etc/nginx/htpasswd/doc;
    }
}

/etc/nginx/conf.d/default.conf

：

user              nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
    access_log  /var/log/nginx/access.log  main;
    sendfile        on;
    keepalive_timeout  65;
    include /etc/nginx/conf.d/*.conf;
}

server {
    listen       20080 default_server;
    include /etc/nginx/default.d/*.conf;

    root /usr/share/nginx/html;
    index index.html;

    location /doc/ {
        auth_basic "Restricted";
        auth_basic_user_file /etc/nginx/htpasswd/doc;
    }
}

文件是CentOS nginx软件包版本1.0.15中的默认文件。这是一个旧版本，但我无法控制CentOS或其软件包版本。

配置您的HAProxy，或使用

端口输入重定向关闭指令。
