nginx 静态资源WEB服务

1、文件读取
Syntax:sendfile on l off；
Default:sendfile off；
Context:http，server，location，if in location
引读：一with-file-aid异步文件读取

2、tcp_nopush
Syntax:    tcp_nopush on | off；
Default:   tcp_nopush 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

Syntax:gzip on|off；
Default:gzip off；
Context:http，server，location，if in location
作用：压缩传输

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_module    -预读gzip功能
http_gunzip_module         -应用支持gunzip的压缩方式
