    nginx核心配置文件中配置含义解析

    1. 设置worker进程的用户,指当然操作系统linux中的用户,会涉及到nginx操作目录或者文件的一些权限,默认为nobody,可根据需要自定义为Linux系统下其他用户。如配置为root用户。

      user  root;
      
    2. worker进程工作数设置,一般来说CPU有几个,就可以设置为几个,或者n-1个。

      worker_processes 1;
      
    3. nginx 日志级别 debug|info|notice|warn|error|crit|alert|emerg,错误级别从左到右越来越大。

      #error_log  logs/error.log;
      #error_log  logs/error.log  notice;
      #error_log  logs/error.log  info;
      
    4. 设置nginx进程pid

      #pid        logs/nginx.pid;
      
    5. 设置工作模式

      events {
      		# 默认使用epoll
          use epoll
          # 每个worker允许连接的客户端最大连接数
          worker_connections  1024;
      }
      
    6. http是指令块,针对于http网络传输的一些指令配置

      http{
      
      }
      
    7. include引入外部配置,提高可读性,避免因为单个配置文件过大

       include       mime.types;
      
    8. 设置日志格式,main为定义的格式名称,如此access_log就可以直接使用这个变量了

      参数名 参数含义
      $remote_addr 客户端ip
      $remote_user 远程客户端用户名,一般为:'-'
      $time_local 时间和时区
      $request 请求的url以及method
      $status 响应状态码
      $body_bytes_send 响应客户端内容字节数
      $http_referer 记录用户从哪个链接跳转过来的
      $http_user_agent 用户所使用的代理,一般来说都是浏览器
      $http_x_forwarded_for 通过代理服务器来记录客户端的ip
    9. sendfile使用高效文件传输,提升传输性能。启用后才能使用tcp_nopush,是指当数据表积累一定大小后才发送,提升了传输效率

      sendfile     on;
      tcp_nopush   on;
      
    10. keepalive_timeout设置客户端与服务端请求的超时时间, 保证客户端多次请求的时候不会重复建立新的连接,避免资源损耗。

      keepalive_timeout  0;
      keepalive_timeout  65;
      
    11. gzip启用压缩,html/js/css压缩后传输会更快。

      gzip  on;
      
    12. server可以在http指定块中设置多个虚拟主机

      • listen监听端口

      • server_name location、ip、域名

      • location请求路由映射,匹配拦截

      • root请求位置

      • index 首页设置

       #server {
          #    listen       80;
          #    listen       somename:8080;
          #    server_name  somename  alias  another.alias;
      
          #    location / {
          #        root   html;
          #        index  index.html index.htm;
          #    }
          #}
