Configuring Server Connections
2. Enter the following command to verify that the loopback alias was created:
# ifconfig lo:dsr
The output should look like this:
lo:dsr Link encap:Local Loopback
inet addr:
cluster-ip
Mask:255.255.255.255
UP LOOPBACK RUNNING MTU:16436 Metric:1
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
/us-
r/local/etc/apache/httpd.conf
). Look for the first line beginning with the Listen directive, and
add another line that looks like this:
Listen
cluster-ip
Where cluster-ip is the DSR-enabled cluster IP. Save your changes to the file.
4. Reboot the Apache server:
# apachectl restart
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.
Configuring a Loopback Interface on Other Systems for DSR
The commands and interfaces used to configure a loopback interface vary slightly between
operating systems, and sometimes between versions of the same operating system. Check the
documentation for your server operating system for instructions on how to configure a loopback
interface. For example, on some BSD systems, the command used in Step 1 in the previous
section would be slightly different, as shown below:
# ifconfig lo0
cluster-ip
netmask
cluster-netmask
alias
Notice that in this case, the netmask used matches the netmask used to configure the cluster on
Equalizer, instead of 255.255.255.255 as in the Linux system example.
