Nginx重定向www。错误的Vhost

Question

嗯我有问题......

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，它才能正常工作并重定向正确。

更简单地说我的问题是http：//正确地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配置中的一个问题。

的 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

我不打算清理和验证您的配置文件，但它们包含几个问题，您应该DRY出来。

关于你的实际问题。

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（在您的情况下为site，因为site2和site3来自该服务器之后;简单的排序）。

实际的解决方案是配置您希望为每台服务器进行的重定向。这个代码段是from another answer of mine在类似的问题上进行的。

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... 

}

重定向non-www to www和www to www。你需要为这3个域中的每个域配置此配置..
