使用nginx反向代理能够有效的将我们的域名绑定到我们的某个项目上，下面以自己的域名绑定项目作为演示。域名为：www.xlecho.com(真实有效能够访问)

刚开始的时候，我看了很多的博客和视频，配置了如下的配置文件。【注意这个无法成功】

user  www www;
worker_processes auto;
error_log  /www/wwwlogs/nginx_error.log  crit;
pid        /www/server/nginx/logs/nginx.pid;
worker_rlimit_nofile 51200;

events
    {
        use epoll;
        worker_connections 51200;
        multi_accept on;
    }

http
    {
        include       mime.types;
      #include luawaf.conf;

      include proxy.conf;

        default_type  application/octet-stream;

        server_names_hash_bucket_size 512;
        client_header_buffer_size 32k;
        large_client_header_buffers 4 32k;
        client_max_body_size 50m;

        sendfile   on;
        tcp_nopush on;

        keepalive_timeout 60;

        tcp_nodelay on;

        fastcgi_connect_timeout 300;

        fastcgi_busy_buffers_size 128k;
        fastcgi_temp_file_write_size 256k;
      fastcgi_intercept_errors on;

        gzip on;
        gzip_min_length  1k;
        gzip_buffers     4 16k;
        gzip_http_version 1.1;
        gzip_comp_level 2;
        gzip_types     text/plain application/javascript application/x-javascript text/javascript text/css application/xml;
        gzip_vary on;
        gzip_proxied   expired no-cache no-store private auth;
        gzip_disable   "MSIE [1-6]\.";

        limit_conn_zone $binary_remote_addr zone=perip:10m;
      limit_conn_zone $server_name zone=perserver:10m;

        server_tokens off;
        access_log off;

      upstream uicps  {
          server 106.12.81.219:10080;
      #   server www.163.com;
      }

server
    {
        listen 888;
        server_name www.xlecho.com;
        index index.html index.htm index.php;
        root  html;

      location / {
        proxy_pass  http://uicps;

        #Proxy Settings
        proxy_redirect     off;
        proxy_set_header   Host     106.12.81.219:10080;  #           $host;不能使用$host变量
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
        proxy_max_temp_file_size 0;
        proxy_connect_timeout      90;
        proxy_send_timeout         90;
        proxy_read_timeout         90;
        proxy_buffer_size          4k;
        proxy_buffers              4 32k;
        proxy_busy_buffers_size    64k;
        proxy_temp_file_write_size 64k;
   }


    }
include /www/server/panel/vhost/nginx/*.conf;
}

错误的原因

在于nginx的版本，很多的nginx的版本原始配置文件设置监听的端口是888，所以一开始我就误以为访问到我自己的项目就直接是通过888端口的，谁知道一直无法访问。（测试的时候用了1.14/1.15/1.8配置文件默认配置888）

这种其实也可以访问，只是需要在配置好的域名后面加上888端口号

正确的配置
