Change the virtual IP address for a virtual host
When you change the virtual IP address of a virtual host, you will also need to update
your name server and to configure applications to recognize the new virtual IP
address. The order in which you perform these tasks is dependent on your application
and the requirements of your site.
You can use mx commands to change the virtual IP address of a virtual host. Complete
these steps:
1. At the command prompt, run the following command:
mx matrix dump > mxdump.out
2. Edit the mxdump.out file, replacing all occurrences of the old IP address with
the new IP address.
3. At the beginning of the mxdump.out file, add a line such as the following to
remove the old IP address from the virtual host configuration:
vhost delete <old_IP_address>
4. Delete any lines in mxdump.out that do not need to change.
5. Run the following command to update the cluster configuration with the new IP
address:
mx --file mxdump.out
Rehost a virtual host
You can use the Rehost option to modify the configuration of a virtual host. For
example, you might want to change the primary for the virtual host or reorder the
backups. To use this option, select the virtual host, right-click, and then select Rehost.
The Virtual Host Rehost window appears.
