nginx

mkdir /usr/local/nginx/conf/vhost
vim /usr/local/nginx/conf/nginx.conf
在http代码段增加 include vhost/*.conf

2.虚拟主机

server {
                    listen 80;
                    server_name  域名;
                    index  index.html index.php;
                    root   /data/www/网站目录;              
                    }

写法2：

server{
                    listen 80;
                    server_name 域名;
                    location / {                                               #location设置匹配规则，/匹配任何请求
                                                    root   /data/www/网站目录;
                                                    index  index.html index.php;
                           }
                }

3.反向代理

server {
            listen 80;
            server_name  域名;
            location /{
                        proxy_pass    http://域名或ip;                   #转发请求至此处定义的域名或ip
                        后端服务器获取用户真实IP
                        proxy_set_header Host $host;
                        proxy_set_header X-Real-IP $remote_addr;
                        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                        }
            }

4.负载均衡

upstream  name{
                server   ip:port1;
                server   ip:port2;
                }
                server {
            listen 80;
            server_name  域名;
            location /{
                        proxy_pass    http://name;                          #使用upstream处定义的名字，转发请求          
                        proxy_set_header Host $host;
                        proxy_set_header X-Real-IP $remote_addr;
                        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                        }
            }
