2.2 主要目录

主要是config和config.default
1

• nginx启动的时候默认找的是config这个配置

• default是为了防止config被修改坏了不能复原时,直接copy一份default改为config即可

• #user  nobody;
  # worker最好与cpu核数保持一致
  worker_processes  1;
  
  #error_log  logs/error.log;
  #error_log  logs/error.log  notice;
  #error_log  logs/error.log  info;
  
  #pid        logs/nginx.pid;
  
  # 事件模块指令，用来指定Nginx的IO模型，Nginx支持的有select、poll、kqueue、epoll 等。不同的是epoll用在Linux平台上，而kqueue用在BSD系统中，对于Linux系统，epoll工作模式是首选
  events {
  		use epoll;
  		# 每个进程最大链接数
  		# 作为反向代理来说，最大并发数量应该是worker_connections * worker_processes/2。因为反向代理服务器，每个  并发会建立与客户端的连接和与后端服务的连接，会占用两个连接
      worker_connections  1024;
  }
