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 matrix 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.
