#### 1.sendfile ####

Syntax:  sendfile on|off;
    Default: sendfile off;
    Context: http, server, location, if in location

引读：`--with-file-aio`异步文件读取

#### 2.tcp\_nopush ####

Syntax: tcp_nopush on | off;
    Default:tcp_nopuush off;
    Context:http,server,location

作用：sendfile开启的情况下，提高网络包的传输效率

#### 3.tcp\_nodelay ####

Syntax:  tcp_nodelay on | off;
    Default: tcp_nodelay on;
    Context: http, server, location

作用：keepalive连接下，提高网络包的传输实时性

#### 4.gzip压缩 ####

Syntax: gzip on | off;
    Default: gzip off;
    Context: http, server, location, if in location

作用：压缩传输

压缩级别

Syntax: gzip_comp_level level;
    Default: gzip_comp_level 1;
    Context: http,server,location

Syntax:  gzip_http_version 1.0|1.1;
    Default: gzip_http_version 1.1;
    Context: http, server, location

扩展nginx压缩模块

http\_gzip\_static\_modult -预读gzip功能

http\_gunzip\_module -应用支持gunzip的压缩方式

server {
        listen       80;
        server_name  localhost;
        
        sendfile on;
        #charset koi8-r;
        access_log  logs/static_access.log  main;
        
        location ~ .*\.(jpg|gif|png)$ {
            gzip on;
            gzip_http_version 1.1;
            gzip_comp_level 2;
            gzip_types text/plain application/javascript application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;
            root  /usr/local/nginx/html/code/images;
        }
    
        location ~ .*\.(txt|xml)$ {
            gzip on;
            gzip_http_version 1.1;
            gzip_comp_level 1;
            gzip_types text/plain application/javascript application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;
            root  /usr/local/nginx/html/code/doc;
        }
        
        location ~ .*\.(htm|html)$ {
            expires 24h;
            root /usr/local/nginx/html/code;
        }
        location ~ ^/download {
            gzip_static on;
            tcp_nopush on;
            root /usr/local/nginx/html/code;
        }
    }

#### 5.expires ####

添加Cache-Control、Expires头

Syntax: expires [modified] time;
    		expires epoch | max |off;
    Default: expires off;
    Context:http,server,location,if in location

location ~ .*\.(htm|html)$ {
     	expires 24h;
    	root /usr/local/nginx/html/code;      
    }

#### 6.跨域访问 ####

location ~ .*\.(htm|html)$ {
            add_header Access-Control-Allow-Origin *; #允许所有网站跨域访问，可以允许单独网址
            add_header Access-Control-Allow-Methods GET,POST,PUT,DELETE,OPTIONS;
            #expires 24h;
            root  /usr/local/nginx/html/code;
    }

#### 7.基于http\_refer防盗链配置模块 ####

location ~ .*\.(jpg|gif|png)$ {
            gzip on;
            gzip_http_version 1.1;
            gzip_comp_level 2;
            gzip_types text/plain application/javascript application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;
     		# 允许http://192.168.127.21 google的获取
            valid_referers none blocked http://192.168.127.21 ~/google\./;
            if ($invalid_referer) {
                return 403;
            }
            root  /usr/local/nginx/html/code/images;
        }
