What My boss want is http(s)://domain.com -> frontEnd service(web), http(s)://domain.com/admin -> backStage service(web)

One domain call: yourDomain

ip call: yourIp

Type like below

<VirtualHost *:80>
  ServerName yourDomain
  ServerAlias www.yourDomain
  ProxyRequests off
  <Proxy *>
    Order allow,deny
    Allow from all
  </Proxy>

  
  ProxyPass /admin http://yourIp:backendPort/
  ProxyPassReverse /admin yourIp:backendPort/
  ProxyPass / http://yourIp:frontEndPort/
  ProxyPassReverse / http://yourIp:frontEndPort/
  ProxyPreserveHost on

</VirtualHost>
