Configuring a Linux System running Apache for DSR

This is an example of how to configure a typical Linux system running Apache 2.0 for DSR:

1. Log into the Linux server as root, and enter the following command to configure a loopback interface:

Substitute the IP address of the DSR-enabled cluster on FortiADC for cluster-ip in the command above. Note that in most Linux distributions, you are configuring an alias for the loopback interface and should specify a netmask of 255.255.255.255 instead of the netmask used to configure the cluster on FortiADC.

2. Enter the following command to verify that the loopback alias was created:

The output should look like this:

3. To configure an Apache 2.0 server for DSR, edit the server configuration file to add a Listen directive for the cluster IP (on many systems, the configuration file is found at /usr/local/etc/apache/httpd.conf). Look for the first line beginning with the Listen directive, and add another line that looks like this:

Where cluster-ip is the DSR-enabled cluster IP. Save your changes to the file.

4. Reboot the Apache server:

You should now be able to send client requests to the cluster IP and port, and get responses directly from the Apache server running on Linux. Remember that static routes on your servers may be necessary, depending on your network configuration.
