Nginx external network access intranet site configuration operation

background:

The site is separated from the front and back ends: vue+springboot

Front-end intranet address: 192.168.1.10:81

API intranet address: 192.168.1.12:8080

External domain name: abc.ab.com External IP: 10.114.XX

need:

The site and static resources can be accessed through the domain name, and the API request data can be accessed

Solution 1: (Prerequisite: external domain name mapping server external IP)

1. nginx configures domain name monitoring and accesses static resources

2.Here comes the point! ! ! The address of the static resource request API is changed from 192.168.1.12:8080 to domain name access method (abc.ab.com:8080)

Restart nginx

Other solutions will be posted after the blogger has verified them! !

Supplementary knowledge: Use nginx to implement reverse proxy and realize external network access to internal network services

Environmental background, the server is Ubuntu:

A server A that can connect to the public network and the intranet, with a public IP address of 61.174.×.×. Another intranet server B has the Jenkins service installed, with an intranet IP address of 192.168.3.12

Steps:

Install nginx on A

sudo apt-get install nginx

After installation, go to the /etc/nginx/sites-enabled directory, open the files in the directory, and change the default port number to 8085.

Then go to the /etc/nginx/conf.d directory and create a new file jenkins.conf. The content of the file is as follows:

server{
listen 8085;
server_name 61.174.171.61;
 
location /{
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-Nginx-Proxy true;
proxy_pass http://192.168.3.12:8080;
proxy_redirect off;
}

Then execute

sudo nginx -t

sudo nginx -s reload

If an error occurs:

nginx: [error] invalid PID number "" in "/run/nginx.pid"

Then execute

sudo nginx -c /etc/nginx/nginx.conf

Then visit 61.174.171.61:8085 on the public Internet to access the Jenkins service on the intranet.
