Apache deployment and configuration

Apache is a web server and is set up to perform the same functions as nginx, serving as a reverse proxy and sending requests to the backend. Here is a configuration example:

NameVirtualHost *:80
<VirtualHost *:80>
    ServerAdmin webmaster@dummy-host.example.com
    ServerName www.a.com
    ProxyRequests Off
    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>
    ProxyPass / http://127.0.0.1:8080/
    ProxyPassReverse / http://127.0.0.1:8080/
</VirtualHost>
 
<VirtualHost *:80>
    ServerAdmin webmaster@dummy-host.example.com
    ServerName www.b.com
    ProxyRequests Off
    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>
    ProxyPass / http://127.0.0.1:8081/
    ProxyPassReverse / http://127.0.0.1:8081/
</VirtualHost>
