Changing Passwords
From UniCluster
Changing the Bootstrap Client Password
A UniCluster Express cluster installation consists of one main node and one or more subordinate nodes.
During the main node installation, you define a Bootstrap Client username and password that is used by all subordinate nodes during their installations. The subordinate nodes contact the main node, using the Bootstrap Client username and password, to receive cluster configuration parameters.
The Bootstrap Client username is totally independent from the user that owns the installation and does not have to be based on an any existing UNIX username.
The Bootstrap Client username and password are configured in an ACL file, located in the UniCluster Express installation directory in /etc/unicluster_bootstrap_service/. The file name is bootstrap_acl.xml. This file is created during installation, using the username and password you enter during the install process.
During installation, you may opt to have the program generate a random password for the Bootstrap Client user. To retrieve this password, or to change the password:
- Open the bootstrap_acl.xml file in vi or another text editor.
- Find the BootstrapPassword parameter.
- Note the password, or revise it.
- Save the file and close.
An example bootstrap ACL file follows:
<?xml version="1.0"?>
<ug:BootstrapACL xmlns:ug="http://schemas.univa.com/2007/07/ug">
<ug:BootstrapUserAccount>
<ug:BootstrapUser>ucluster</ug:BootstrapUser>
<ug:BootstrapPassword>O6TshgpT2</ug:BootstrapPassword>
</ug:BootstrapUserAccount>
</ug:BootstrapACL>
