Nginx 重定向 www.错误的虚拟主机

Question

嗯，我有个问题……

浏览器将我的 3 个虚拟站点 www.site1.com www.site2.com www.site3.com 重定向到 www.site1.com，只有当我使用 http://site3.com / http://site2.com 时它才能正常工作并正确重定向。

更简单地说，我的问题是 http:// 正确重定向到我的虚拟实体， www 没有。

www.site2.com -> www.site1.com     (redirects to wrong vhost)
http://site2.com -> www.site2.com  works!

我的设置是 Nginx + Gunicorn + Django，但我坚信这是我的 Nginx 配置中的问题。

Nginx.conf

user www-data;
worker_processes 4;
pid /run/nginx.pid;

events {
        worker_connections 768;
        # multi_accept on;
}

http {

        ##
        # Basic Settings
        ##

        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;



        include /etc/nginx/mime.types;
        default_type application/octet-stream;

        ##
        # Logging Settings
        ##

        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;

        ##
        # Gzip Settings
        ##

        gzip on;
        gzip_disable "msie6";

    text/javascript;



        ##
        # Virtual Host Configs
        ##


        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;
}

Answer 1

我不会清理和验证您的配置文件，但它们包含几个问题，您应该 DRY 解决它们。

关于您的实际问题。

1. 您尚未配置任何重定向，因此 nginx 很乐意将这些子域重定向到您的默认服务器。
2. 您尚未配置默认服务器，而 nginx 只是使用第一个定义的服务器作为默认服务器（在您的情况下，site 因为site2 和site3 紧随其后；简单排序）。李>

实际的解决方案是为每个服务器配置您希望发生的重定向。这个 sn-p 是在 from another answer of mine 上针对类似问题拍摄的。

server {
    #listen 80 is default
    server_name www.example.com;
    return 301 $scheme://example.com$request_uri;
}

server {
    #listen 80 is default
    server_name example.com;
    ## here goes the rest of your conf...
}

Answer 2

你需要

server {
    listen       80;
    server_name  mysite1.com;
    return       301 http://www.mysite1.com$request_uri;
}

server {
    listen      80;
    server_name www.mysite1.com;
    # other stuff... 

}

这会重定向non-www to www 和www to www。您需要为这 3 个域中的每一个域进行此配置..
