Linux install and configure pound reverse proxy for Apache http / https web server

Pound is a reverse proxy and load balancer for the HTTP and HTTPS protocols. It can be used to distribute incoming traffic to multiple servers, such as an Apache HTTP server, and provide additional features such as SSL offloading, URL rewriting, and request filtering.

To install and configure Pound as a reverse proxy for an Apache HTTP/HTTPS web server on a Linux system, you will need to follow these steps:

1. Install Pound using the package manager for your distribution. For example, on a Debian-based system, you can use the apt-get command:

apt-get install pound

On a Red Hat-based system, you can use the yum command:

yum install pound

2. Once Pound is installed, edit the configuration file /etc/pound/pound.cfg to set up the reverse proxy. You can specify the listening port, the backend servers, and other options in this file. Here is an example configuration that listens on port 80 and forwards requests to an Apache server running on the localhost on port 8080:

ListenHTTP
  Address 0.0.0.0
  Port 80
  Service
    BackEnd
      Address 127.0.0.1
      Port 8080
    End
  End
End

3. If you want to enable HTTPS, you can add a ListenHTTPS section to the configuration file and specify the SSL certificate and key files. For example:

ListenHTTPS
  Address 0.0.0.0
  Port 443
  Cert "/etc/ssl/certs/server.crt"
  Key "/etc/ssl/private/server.key"
  Service
    BackEnd
      Address 127.0.0.1
      Port 8080
    End
  End
End

4. Save the configuration file and start the Pound service. On a Debian-based system, you can use the systemctl command:

systemctl start pound

On a Red Hat-based system, you can use the service command:

service pound start

5. If everything is configured correctly, Pound should now be acting as a reverse proxy for your Apache HTTP/HTTPS server. You can access the Apache server through Pound by using the listening address and port specified in the Pound configuration file.

Keep in mind that this is just a basic example of how to configure Pound as a reverse proxy for an Apache HTTP/HTTPS server. There are many other options and configurations that you can use to customize the behavior of Pound. You may want to consult the Pound documentation or a reference guide for more information.
