nginx虚拟主机配置及负载均衡示例

两个虚拟主机(纯静态-html 支持) - Two Virtual Hosts, Serving Static Files

http {
    server {
        listen          80;
        server_name     www.domain1.com;
        access_log      logs/domain1.access.log main;
        location / {
            index index.html;
            root  /var/www/domain1.com/htdocs;
        }
    }
    server {
        listen          80;
        server_name     www.domain2.com;
        access_log      logs/domain2.access.log main;
        location / {
            index index.html;
            root  /var/www/domain2.com/htdocs;
        }
    }
}

虚拟主机标准配置(简化) - A Default Catchall Virtual Host

http {
    server {
        listen          80 default;
        server_name     _ *;
        access_log      logs/default.access.log main;
        location / {
            index index.html;
            root  /var/www/default/htdocs;
        }
    }
}

在父文件夹中建立子文件夹以指向子域名 - Wildcard Subdomains in a Parent Folder

这是一个添加子域名(或是当DNS已指向服务器时添加一个新域名)的简单方法。需要注意的是，我已经将FCGI配置进该文件了。如果你只想使服务器为静态文件服务，可以直接将FCGI配置信息注释掉，然后将默认主页文件变成index.html。

这个简单的方法比起为每一个域名建立一个 vhost.conf 配置文件来讲，只需要在现有的配置文件中增加如下内容：

This is just a really easy way to keep adding new subdomains, or to add new domains automatically when DNS records are pointed at the server. Note that I have included FCGI here as well. If you want to just serve static files, strip out the FCGI config and change the default document to index.html. Rather than creating a new vhost.conf file for every domain, just create one of these:

server {
        # Replace this port with the right one for your requirements
        # 根据你的需求改变此端口
        listen       80;  #could also be 1.2.3.4:80 也可以是1.2.3.4:80的形式
        # Multiple hostnames seperated by spaces.  Replace these as well.
        # 多个主机名可以用空格隔开，当然这个信息也是需要按照你的需求而改变的。
        server_name  star.yourdomain.com *.yourdomain.com www.*.yourdomain.com;
        #Alternately: _ *
        #或者可以使用：_ * (具体内容参见本维基其他页面)
        root /PATH/TO/WEBROOT/$host;
        error_page  404              http://yourdomain.com/errors/404.html;
        access_log  logs/star.yourdomain.com.access.log;
        location / {
            root   /PATH/TO/WEBROOT/$host/;
            index  index.php;
        }
        # serve static files directly
        # 直接支持静态文件 (从配置上看来不是直接支持啊)
        location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|html)$ {
            access_log        off;
            expires           30d;
        }
        location ~ .php$ {
          # By all means use a different server for the fcgi processes if you need to
          # 如果需要，你可以为不同的FCGI进程设置不同的服务信息
          fastcgi_pass   127.0.0.1:YOURFCGIPORTHERE;
          fastcgi_index  index.php;
          fastcgi_param  SCRIPT_FILENAME  /PATH/TO/WEBROOT/$host/$fastcgi_script_name;
          fastcgi_param  QUERY_STRING     $query_string;
          fastcgi_param  REQUEST_METHOD   $request_method;
          fastcgi_param  CONTENT_TYPE     $content_type;
          fastcgi_param  CONTENT_LENGTH   $content_length;
          fastcgi_intercept_errors on;
        }
        location ~ /\.ht {
            deny  all;
        }
     }

一个简单的负载均衡的示例，把www.domain.com均衡到本机不同的端口，也可以改为均衡到不同的地址上。

http {
    upstream myproject {
        server 127.0.0.1:8000 weight=3;
        server 127.0.0.1:8001;
        server 127.0.0.1:8002;
        server 127.0.0.1:8003;
    }

    server {
        listen 80;
        server_name www.domain.com;
        location / {
            proxy_pass http://myproject;
        }
    }
}
