First introduction to nginx configuration file--nginxconf nginx configuration tcp nginx configuration jsp nginx live broadcast configuration

1. Open the nginx configuration file nginx.conf, and you can find that its initial content is as follows:

#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;
	    proxy_pass http://192.168.56.202:8080;	
        }

        #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;
    #    }
    #}

}

can be easily understood as the following blocks:

...				#全局块

events				#event块
{
...
}
http				#http块
{
...				#http全局块	
}
server				#server块
{
...				#server全局块
	location [PATTERN]	#location块
	{
	...	
	}
	location [PATTERN]	#location块
	{
	...	
	}
}
server				#server块
{
...
}
...
}

2. The role of each block

Global block: main settings Some configurations that affect the overall operation of the server have a global scope. Usually includes the user of the server
, the worker process allowed to be generated (this configuration item is generally the core number of the server host), the storage path of the nginx process pid
, the storage path and type of the log, and the introduction of the configuration file

events block : Mainly set some parameters that affect the network connection between the server and the user. Commonly used ones include: whether to enable serialization of network connections under
multiple worker processes, the master allows receiving multiple network connections at the same time, and each
worker process can simultaneously The maximum number of connections supported.

http block: Most of the general configuration proxy, cache, log definition and other functions and third-party configurations are set in this module

server block: related to the virtual host

location block: for requests Processing, address targeting, response control

The above has introduced the nginx configuration file-nginxconf for the first time, including the content of nginx and configuration files. I hope it will be helpful to friends who are interested in PHP tutorials.
