nginx为反向代理服务器，可以反向代理不同域名转向不同的具体服务器。可以用于负载压力或是同一台机器使用不同域名进行访问。
以下片段是服务器配置：

#proxy server 在这里配置一个代理名称，最重要的是server指向的地址。
如下：
upstream webvoc.com{
server 115.28.213.130:8080 weight=2;
}
名称为webvoc.com的域名指向了115.28.213.130:8080的实际地址。
weight=2向的反向代理权重，当多个负载服务器工作时，可以加大转向某个服务器的机率。
upstream www.webvoc.com{
server 115.28.213.130:8080 weight=2;
}
表明使用www.webvoc.com指向同一个网站。
server{
listen 80;
server_name webvoc.com;

access_log /tmp/vm_access.log;

server:是一个完整的服务器转向规则说明：
listen：是要侦听的端口号，如果使用域名访问，这里可全部设置为80端口。
server_name：这个就是上面提到upstream后面的名字。一般情况下和域名相同，但是可以不一致。
这个nginx配置中，有一个站点为PHP站点，直接使用nginx作解析。配置代码如下：
server {
listen 8011;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root /usr/local/www;
index index.php;
}
location /svn {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Proto https;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:8099/svn/;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/local/www;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root /usr/local/www;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
