Nginx的的目录结构,基本运行原理及基本配置文件

Nginx目录结构

 

 

主要的目录是conf,html,及sbin。

• conf目录放的是核心配置文件：

  

   

  

   

  

   

  

   

  

   刚安装好的nginx.conf如下：

• #user nobody;
  worker_processes 1;

  #error_log logs/error.log;
  #error_log logs/error.log notice;
  #error_log logs/error.log info;

  #pid logs/nginx.pid;

  
  events {
  worker_connections 1024;
  }

  
  http {
  include mime.types;
  default_type application/octet-stream;

  #log_format main '$remote_addr - $remote_user [$time_local] "$request" '
  # '$status $body_bytes_sent "$http_referer" '
  # '"$http_user_agent" "$http_x_forwarded_for"';

  #access_log logs/access.log main;

  sendfile on;
  #tcp_nopush on;

  #keepalive_timeout 0;
  keepalive_timeout 65;

  #gzip on;

  server {
  listen 80;
  server_name localhost;

  #charset koi8-r;

  #access_log logs/host.access.log main;

  location / {
  root html;
  index index.html index.htm;
  }

  #error_page 404 /404.html;

  # redirect server error pages to the static page /50x.html
  #
  error_page 500 502 503 504 /50x.html;
  location = /50x.html {
  root html;
  }

  # proxy the PHP scripts to Apache listening on 127.0.0.1:80
  #
  #location ~ \.php$ {
  # proxy_pass http://127.0.0.1;
  #}

  # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
  #
  #location ~ \.php$ {
  # root html;
  # fastcgi_pass 127.0.0.1:9000;
  # fastcgi_index index.php;
  # fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
  # include fastcgi_params;
  #}

  # deny access to .htaccess files, if Apache's document root
  # concurs with nginx's one
  #
  #location ~ /\.ht {
  # deny all;
  #}
  }

  
  # another virtual host using mix of IP-, name-, and port-based configuration
  #
  #server {
  # listen 8000;
  # listen somename:8080;
  # server_name somename alias another.alias;

  # location / {
  # root html;
  # index index.html index.htm;
  # }
  #}

  
  # HTTPS server
  #
  #server {
  # listen 443 ssl;
  # server_name localhost;

  # ssl_certificate cert.pem;
  # ssl_certificate_key cert.key;

  # ssl_session_cache shared:SSL:1m;
  # ssl_session_timeout 5m;

  # ssl_ciphers HIGH:!aNULL:!MD5;
  # ssl_prefer_server_ciphers on;

  # location / {
  # root html;
  # index index.html index.htm;
  # }
  #}

  }

• 去掉注释的简单版如下：

• worker_processes 1; #允许进程数量，建议设置为cpu核心数或者auto自动检测，注意Windows服务器上虽然可以启动多个processes，但是实际只会用其中一个

  events {
  #单个进程最大连接数（最大连接数=连接数*进程数）
  #根据硬件调整，和前面工作进程配合起来用，尽量大，但是别把cpu跑到100%就行。
  worker_connections 1024;
  }

  
  http {
  #文件扩展名与文件类型映射表(是conf目录下的一个文件)
  include mime.types;
  #默认文件类型，如果mime.types预先定义的类型没匹配上，默认使用二进制流的方式传输
  default_type application/octet-stream;

  #sendfile指令指定nginx是否调用sendfile 函数（zero copy 方式）来输出文件，对于普通应用，必须设为on。如果用来进行下载等应用磁盘IO重负载应用，可设置为off，以平衡磁盘与网络IO处理速度。
  sendfile on;
  
  #长连接超时时间，单位是秒
  keepalive_timeout 65;

  #虚拟主机的配置
  server {
  #监听端口
  listen 80;
  #域名，可以有多个，用空格隔开
  server_name localhost;

  #配置根目录以及默认页面
  location / {
  root html;
  index index.html index.htm;
  }

  #出错页面配置
  error_page 500 502 503 504 /50x.html;
  #/50x.html文件所在位置
  location = /50x.html {
  root html;
  }
  
  }

  }
