Nginx主配置文件各参数说明——筑梦之路

Nginx主配置文件模板说明
# 由谁来执行worker，master是由root执行的
# 默认是由nobody来执行worker
#user  nobody;

# worker进程数量，和cpu数量相关的，一般是cpu核心数 - 1
worker_processes  2;

# nginx 日志级别 从低到高
# debug info notice warn error crit
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

# nginx 进程号
#pid        logs/nginx.pid;


# 事件处理
events {
    # 默认使用epoll,windows 系统用不了，这个是使用linux 的epoll，处理异步请求的，容纳更高的并发
    # use epoll;
    # 每个worker允许连接客户端的最大连接数
    worker_connections  1024;
}


# http相关网络传输指令块
http {
    # 导入外部的配置，提高可读性；mime.types 是外部文件，相对路径，和nginx.conf这个核心配置在同一个文件夹下面
    include       mime.types;

    # 默认的类型
    default_type  application/octet-stream;

    # 记录日志的格式，access_log文件里
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
    # 只要有请求，那么都会记录
    access_log  logs/access.log  main;

    # 用于文件高效传输，提升nginx性能
    sendfile        on;
    # 只有sendfile开启了，才可以用，当数据包达到一定数目，才开始传输
    #tcp_nopush     on;

    # 客户端连接服务器的超时时间，以s为单位的，保证客户端多次请求不会建立重复连接
    # 打开会占用一丢丢资源
    #keepalive_timeout  0;
    keepalive_timeout  65;

    # 启用压缩，html/js/css压缩之后，传输更快，节约带宽
     gzip  on;
    # 限制最小压缩，小于1个字节的文件不会压缩
     gzip_min_length 1;
    # 定义压缩级别 （压缩比，文件越大，压缩越多，但是cpu使用会越多）
     gzip_comp_level 3;
    # 定义压缩文件的类型
     gzip_types text/plain application/javascript application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jepg image/gif image/png application/json;
