**nginx.conf配置**

建议：自行找到对应
    worker_processes  auto;    #工作进程：根据硬件调整
    
    worker_connections  1024;    #工作进程的最大连接数量
    
    
    #配置多站点    http中加入此行
    include /路径/*.conf;    ＃主要是加入此行，如有则忽略
    
    
    #在新建的.conf加入server
    server
    {
            listen 80;
            server_name 域名;
            location / {
    	        root    地址;
                index  index.html;
            }
            error_page 404 /404.html;
    		location = /40x.html{
                root   html;
    		}
            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
                root   html;
            }
    }

反向代理和网址

#反向代理
    server {
            listen       80;
            server_name  域名;
            location / {
    	        proxy_pass   http://127.0.0.1:8096;
            }
            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
                root   html;
            }
     }
     
     
    #网站
    server {
            listen       80;
            server_name  域名;
            root	F:/resources;
            index  index.html index.htm;
     }

跨域

#nginx设置允许跨域
    #*代表接受任意域名的请求
    add_header Access-Control-Allow-Origin *;
    #是否允许发送Cookie
    add_header Access-Control-Allow-Credentials 'true';
    #请求类型
    add_header Access-Control-Allow-Methods 'GET,POST,OPTIONS';
    #预检请求
    add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';
    #自定义请求头无法操作
    add_header Access-Control-Expose-Headers 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range';

注：目标URL就是在Tomcat上域名/IP

Nginx反爬虫处理

1.进入到nginx安装目录下的conf目录，将如下代码保存为 agent_deny.conf
    
    #禁止Scrapy等工具的抓取
    if ($http_user_agent ~* (Scrapy|Curl|HttpClient)) {
         return 403;
    }
    #禁止指定UA及UA为空的访问
    if ($http_user_agent ~* "FeedDemon|Indy Library|Alexa Toolbar|AskTbFXTV|AhrefsBot|CrawlDaddy|CoolpadWebkit|Java|Feedly|UniversalFeedParser|ApacheBench|Microsoft URL Control|Swiftbot|ZmEu|oBot|jaunty|Python-urllib|lightDeckReports Bot|YYSpider|DigExt|HttpClient|MJ12bot|heritrix|EasouSpider|Ezooms|^$" ) {
         return 403;             
    }
    #禁止非GET|HEAD|POST方式的抓取
    if ($request_method !~ ^(GET|HEAD|POST)$) {
        return 403;
    }
    # 禁止百度及谷歌等
    if ($http_user_agent ~* "qihoobot|Baiduspider|Googlebot|Googlebot-Mobile|Googlebot-Image|Mediapartners-Google|Adsbot-Google|Feedfetcher-Google|Yahoo! Slurp|Yahoo! Slurp China|YoudaoBot|Sosospider|Sogou spider|Sogou web spider|MSNBot|ia_archiver|Tomato Bot”)  {
        return 403;
    }
    2.然后，在网站相关配置中的 server段插入如下代码：
    
    include agent_deny.conf;
    
    3.保存后，执行如下命令，平滑重启nginx即可：
    
    /usr/local/nginx/sbin/nginx -s reload

负载均衡

upstream配置：
    
    在http配置下增加upstream配置即可：
    
    upstream nodes {
    #监控server的80端口，weigh为权重，2每访问两次，3访问一词
    
    server 192.168.0.1:8080 weigh=2;
    
    server 192.168.0.2:8080;
    
    }
    
    
    #server配置
    location / {  
            proxy_pass http://nodes;  
            index  index.html index.htm;  
    }
