Port based reverse proxy in Apache Web server

Question

I have two web applications http://app1:8080 and http://app2:3000 running on two different ports and different machines. I have to pass the applications traffic through Apache web server, http://myapp.

Now, we can configure apache webserver as reverse proxy based by mounting application to specific location. For example,

ProxyPass /app1/ http://app1:8080/
ProxyPass /app2/ http://app2:3000/

ProxyPassReverse /app1/ http://app1:8080/
ProxyPassReverse /app2/ http://app2:3000/

After this mapping, http://myapp/app1 points to http://app1:8080 and http://myapp/app2 points to http://app2:3000.

But, my requirement is http://myapp:8080 should point to http://app1:8080 and http://myapp:3000 should point to http://app2:3000. Kindly guide me how to reverse proxy the traffic on the basis of ports in apache web server.

Answer 1

You would need to create two separate Virtual Hosts, with the different ports you want.

You would need

<VirtualHost *:8080>
    ...
</VirtualHost>

<VirtualHost *:3000>
    ...
</VirtualHost>

You also will need to set Apache Listen directives for both those ports

Listen 8080, 3000
