    #如果不是域名访问，就直接返回444错误
    server {

	    return       444;

Nginx共用一个端口指向不同程序

#主要通过域名判断
    server {
        listen 80;
        server_name 域名1;
        access_log /data/wwwlogs/v.4xx.me_nginx.log combined;
        index index.html index.htm index.jsp;
        root /data/wwwroot/v.4xx.me;    #可不需要
        
        #error_page 404 /404.html;
        #error_page 502 /502.html;
        location ~ {
            proxy_pass http://127.0.0.1:8080;
            include proxy.conf;
        }
    }
    server {
        listen 80;
        server_name 域名2;
        access_log /data/wwwlogs/v.4xx.me_nginx.log combined;
        index index.html index.htm index.jsp;
        root /data/wwwroot/v.4xx.me;    #可不需要
        
        #error_page 404 /404.html;
        #error_page 502 /502.html;
        location ~ {
            proxy_pass http://127.0.0.1:8080;
            include proxy.conf;
        }
    }

Nginx负载均衡配置

#tomcat例子，php同理
upstream tomcats {
         # session共享
         session_sticky cookie=SESSION.V.4XX.ME fallback=on mode=insert option=direct;
         server 127.0.0.1:9001 weight=1;
         server 192.168.128.1:80 weight=1;  #weight权重，可负载内网机器
   	}

server {
        listen       80;
        server_name  域名;
        location / { 
        	session_sticky_hide_cookie upstream=tomcats;    # session共享
            proxy_pass http://tomcats;
            include proxy.conf;
        }
    }

Nginx开启Https

#需要nginx先安装了ssl相关模块

#php typeoch博客的配置，用的fastcgi_pass unix:/dev/shm/php-cgi.sock;
server {
  listen 80;
  listen 443 ssl http2;
  ssl_certificate /usr/local/tengine/conf/ssl/4xx.me_ssl.crt;       #ssl证书路径
  ssl_certificate_key /usr/local/tengine/conf/ssl/4xx.me_ssl.key;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers EECDH+CHACHA20:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;
  ssl_prefer_server_ciphers on;
  ssl_session_timeout 10m;
  ssl_session_cache builtin:1000 shared:SSL:10m;
  ssl_buffer_size 1400;
  add_header Strict-Transport-Security max-age=15768000;
  ssl_stapling on;
  ssl_stapling_verify on;
  server_name 4xx.me;
  access_log /data/wwwlogs/4xx.me_nginx.log combined;
  index index.html index.htm index.php;
  root /data/wwwroot/4xx.me;
  if ($ssl_protocol = "") { return 301 https://$host$request_uri; }     #http请求自动301跳转到https

  if (!-e $request_filename) {  #重定向
        rewrite ^(.*)$ /index.php$1 last;
    }
  location ~ [^/]\.php(/|$) {
      fastcgi_pass unix:/dev/shm/php-cgi.sock;
      fastcgi_index index.php;
      
    fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;

    fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
    fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

    fastcgi_param  REMOTE_ADDR        $remote_addr;
    fastcgi_param  REMOTE_PORT        $remote_port;
    fastcgi_param  SERVER_ADDR        $server_addr;
    fastcgi_param  SERVER_PORT        $server_port;
    fastcgi_param  SERVER_NAME        $server_name;

    # PHP only, required if PHP was built with --enable-force-cgi-redirect
    fastcgi_param  REDIRECT_STATUS    200;

      set $path_info "";
	  set $real_script_name $fastcgi_script_name;
	  if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
	          set $real_script_name $1;
	          set $path_info $2;
	     }
      fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
      fastcgi_param SCRIPT_NAME $real_script_name;
      fastcgi_param PATH_INFO $path_info;
    }

  location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|mp4|ico)$ {

#java tomcat配置
server {
  listen 80;
  listen 443 ssl http2;
  ssl_certificate /usr/local/tengine/conf/ssl/4xx.me_ssl.crt;       #ssl证书路径
  ssl_certificate_key /usr/local/tengine/conf/ssl/4xx.me_ssl.key;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers EECDH+CHACHA20:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;
  ssl_prefer_server_ciphers on;
  ssl_session_timeout 10m;
  ssl_session_cache builtin:1000 shared:SSL:10m;
  ssl_buffer_size 1400;
  add_header Strict-Transport-Security max-age=15768000;
  ssl_stapling on;

  server_name 域名;
  access_log /data/wwwlogs/4xx.me_nginx.log combined;
  index index.html index.htm index.jsp;
  root /data/wwwroot/4xx.me;
  if ($ssl_protocol = "") { return 301 https://$host$request_uri; }     #http请求自动301跳转到https

   #error_page 404 /404.html;
    #error_page 502 /502.html;
    location ~ {
        proxy_pass http://127.0.0.1:8080;
        include proxy.conf;
    }

}

禁止通过IP访问

#如果不是域名访问，就直接返回444错误
    server {  
	    listen       80  default_server;  
	    server_name  _;  
	    return       444;  
	} 

设置访问流量并发速率，可防御少量ddos、cc流量攻击

limit_req_zone $binary_remote_addr zone=qpscon:10m rate=10r/s;   #1秒接收10个请求
server {
    listen       80;
    server_name  域名;
    location / { 
        limit_req zone=qpscon burst=10 nodelay; #burst 突发流量时10个请求缓冲
        proxy_pass http://tomcats;
        include proxy.conf;
    }
}

php tomcat配置上边的例子中有，就不在赘述了
