Different ports of nginx are mapped to port 80, http and https are requested at the same time

location / {
    proxy_pass http://localhost:8090;
    proxy_redirect default ;
}
location /xcx/{
   proxy_pass http://localhost:8091/;    
   proxy_redirect default;
}
location / {
    proxy_pass http://localhost:8090;
    proxy_redirect default ;
}
location /xcx/{
   proxy_pass http://localhost:8091/;    
   proxy_redirect default;
}
如果想通过 http://localhost:/xcx/a.html访问 http://localhost:8091/
则 proxy_pass http://localhost:8091/;
最后一定要加反斜杠，要不然会报404;

Nginx matching rules

In order to achieve the expected function, you need to add multiple location matching rules to port 443 under the Nginx configuration file. The rules are described as follows:

mode	meaning
location = /uri	= Means exact match, only a complete match can take effect
location ^~ /uri	^~ prefix match the URL path, and before the regular.
location ~ pattern	The beginning indicates case-sensitive regular matching
location ~* pattern	The beginning indicates case-insensitive regular matching
location /uri	Without any modifiers, it also means prefix matching, but after regular matching
location /	General matching, any request that does not match other locations will be matched, which is equivalent to default in switch

In the case of multiple location configurations, the matching order is:

1. Exact match first =

2. Second prefix matching^~

3. Followed by regular matching in the order in the file

4. Then match the prefix match without any modification.

5. Finally it is handed over / general matching

When a match is successful, stop the match and process the request according to the current match rule

Summary: So the key to the realization of requirements is to use different matching rules to map the corresponding ports.

https443 port configuration multi-port mapping

Under the configured port 443, continue to add location rules

# HTTPS server
#
server {
listen 443;
server_name localhost;
ssl on;
root html;
index index.html index.htm;
*ssl证书配置规则*
location / {
proxy_pass *服务器域名*;
}
location /testA {
proxy_redirect off;
proxy_pass http://localhost:12345;
}
location /testB{
proxy_redirect off;
proxy_pass http://localhost:23456;
}
}

After saving the modification, proceed to the execution path of nginx, first test whether the configuration file is correct:

# /usr/local/nginx/sbin/nginx -t

If everything is normal, different service requests can be completed externally through https://server domain name/testA and https://server domain name/testB.

node background running

1. Use forever

1. Install forever: npm install forever -g

2. Start the service: service forever start

3. Use forever to start the js file: forever start index.js

4. Stop the js file: forever stop index.js

5. Start the js file and output the log file: forever start -l forever.log -o out.log -e err.log index.js

6. Restart the js file: forever restart app.js

7. View the running process:forever list

8. Stop the service under pid:forever stop [pid]

9. Stop all services:forever stopall

netstat -tln | grep 8000

result:
