About forward and reverse proxy
https://www.cnblogs.com/ysocean/p/9392908.html#_label0
The core part actually does the mapping of the local domain name, and proxy to the product homepage address http://192.168.56.1:10200/ by monitoring port 80 (default) of gulimall.com
The following is a detailed analysis and steps
1. Configure domain name mapping
The hosts file under C:\Windows\System32\drivers\etc can also be modified
Here we use a software switchHosts to modify the mapping, the download link is as follows

Create a new local plan, and then enter the corresponding mapping application
Originally accessed kibana in the virtual machine
Now access kibana in the virtual machine
Set nginx to start and start automatically

You can see that visiting http://gulimall.com/ actually visited the homepage of nginx
3. Modify the nginx configuration to achieve proxy access to the product homepage

The reverse proxy is successful, it will be a little troublesome, do different services have to configure reverse proxy in nginx, and then prepare to reverse proxy to the gateway
