Second, Nginx server Basic Configuration command

The default nginx server configuration file is stored in the installation directory Conf, and the master profile is named Nginx.conf.

The default nginx.conf in the/usr/local/nginx directory, the last compiler installation Nginx main configuration file is stored under/etc/nginx.

Here are some comments about the nginx.conf

  The nginx.conf consists of three parts, the core (global), the events block, and the HTTP block. In an HTTP block, it also contains HTTP global blocks, multiple server blocks. Each server block also contains server global and multiple location1. A configuration block nested within the same configuration, with no order relationship between the individual.

First, Core:

The global block is a part of the default profile from the beginning to the events block, mainly to set some configuration directives that affect the overall operation of the Nginx server. The scope of these directives is the Nginx service global.

User syntax: User User[group] Default: Nobody nobody specifies the Nginx worker process to run users, default is nobody account Error_log syntax: Error_log file [Debug | info | noti Ce | Warn | Error | Crit]   default: ${prefix}/logs/error.log   set the location and level of error logs. PID   Syntax: PID file   process ID stores files. You can use Kill-hup Cat/var/log/nginx.pid/to reload the Nginx configuration file.     worker_processes   Syntax: worker_processes   Number Default value: 1   Specifies how many worker processes. Nginx can use multiple worker processes.

Change number to 3, and then perform PS Ax | With the exception of the master process, you can see that 3 worker processes have been generated.

II. Events Block

  The commands involved in the events block mainly affect the network connection between the Nginx server and the user. Use Epoll; #说明使用哪种事件模型, default is Epoll, can not be written. Worker_connections number; #主要用来设置允许每一个worker The maximum connections that the process is open at the same time. Clients = Worker_connections * work_process, set worker_connections according to the actual situation.

Third, HTTP module:

The instructions in the HTTP module include the introduction of the file, the Mime-type definition, the log definition, whether to use Sendfile transfer file, the connection timeout, the maximum number of single link requests, and so on.

Include       mime.types;default_type  application/octet-stream; commonly used browsers can display a wide variety of files such as html,xml,gif and flash, media resources and so on. The browser distinguishes these resources by using the MIME Type. Default_type configures the MIME type used to handle front-end requests.

The Nginx server supports configuration of the service log format, size, output, etc. Access_log Specify the path log_format  Specify the log format specific parameters can be consulted: http://nginx.org/en/docs/http/ngx_http_log_module.html

Sendfile on | Off;   Turn sendfilekeepalive_timeout timeout on or off, which is 65s by default. Gzip on       Whether gzip compression is turned on, default disable

Four, server,location module

Location [= | ~ | ~* | ^~] URI {...} =, requires the string and URI strictly match ~, with regular, case-sensitive ~*, with regular, not case-sensitive ^~, do not do pattern matching priority: The first is =, the second is ~;

Note: For HTTP modules, Server,location is only a minor annotation. Virtual host, rewrite and other functions, will be written in subsequent blog.
