nginx 虚拟主机配置

user nginx;     #代表使用的用户
worker_processes auto;  #工作衍生进程数,一般代表系统cpu核数一到两倍最好
error_log /var/log/nginx/error.log;     #错误日至文件
pid /run/nginx.pid;     #设置pid存放路径,pid是控制系统中的一个重要的控制文件

# Load dynamic modules. See /usr/share/nginx/README.dynamic.

#设置最大链接数

    gzip on;#开启gizp压缩，设置用户访问时，是否开启压缩功能，提高文件数据传输速度
    gzip_min_length 1k;#需要压缩的文件最小1k
    gzip_buffers 4 16k;#申请内存大小来存储压缩的文件,4个16k的数据流
    gzip_http_version 1.1;#gzip技术支持的http版本1.1
    #以上为最常用的配置
    gzip_vary on;#首先判断客户端是否支持gzip压缩技术,不支持的不就不进行gzip技术压缩
