Nginx作用和配置案例

# Nginx 配置文件示例 (nginx.conf)

http {
    # 开启服务器实时gzip
    gzip on;
    # 开启静态gz文件返回, 例如 /dist 文件夹的gz文件，其他的是实时压缩
    gzip_static on;
    # 启用gzip压缩的最小文件，小于设置值的文件将不会压缩
    gzip_min_length 1k;
    # 设置压缩所需要的缓冲区大小
    gzip_buffers 32 4k;
    # 设置gzip压缩针对的HTTP协议版本
    gzip_http_version 1.0;
    # gzip 压缩级别，1-9，数字越大压缩的越好，也越占用CPU时间
    gzip_comp_level 7;

    # 是否在http header中添加Vary: Accept-Encoding，建议开启
    gzip_vary on;
    # 禁用IE 6 gzip
