• Global block: a configuration instruction that configures the overall operation of the server
  Like worker_processes 1; Configuration of processing concurrency
• events block: affects the network connection between the Nginx server and the user
  Like worker_connections 1024; The maximum number of connections supported is 1024
• http block
  It also includes two parts:
  http global block
  server block

Reverse proxy configuration

1. Listen to the port. If you listen, turn to another port
   Listen to port 80 and turn to port 8080
   visit http://192.168.64.123:80 Forward request to http://192.168.64.123:8080/

server {
    listen       80; # Listening port
    server_name  localhost;   #Monitor ip

    #charset koi8-r;

    #access_log  logs/host.access.log  main;

    location / {
        root   html;
        proxy_pass http://192.168.64.123:8080/;  # Proxy address 
        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;
    #}
}

1. Jump to services on different ports according to the access path
   nginx listening port is 9001,
   visit http://192.168.64.123:9001/edu/ Jump directly to http://192.168.64.123:8081/edu/
   visit http://192.168.64.123:9001/vod/ Jump directly to http://192.168.64.123:8080/vod/
   to configure

server {
    listen       9001;
    #listen       somename:8080;
    server_name  192.168.64.123;

    location ~ /edu/ {
        proxy_pass http://192.168.64.123:8081;
    }
    location ~ /vod/ {
        proxy_pass http://192.168.64.123:8080;
    }
}

location ~ /vod / regular expression description in configuration

• =: before using for URIs without regular expressions, the request string and the uri must match strictly. If they match
  If successful, stop the drill down and process the request immediately.
• ~: used to indicate that the uri contains regular expressions and is case sensitive.
• ~*: used to indicate that the uri contains regular expressions and is case insensitive.
• ^~: ask the Nginx server to find the identification uri and request word before using it for URIs without regular expressions
  After the location with the highest string matching degree, the request is processed immediately with this location instead of using the regular uri in the location block to match the request string.
