Configuring 'ricci_pw.txt'

	There is no (practical) upper limit to the number of ''Anvil!''s that a given dashboard can support.		There is no (practical) upper limit to the number of ''Anvil!''s that a given dashboard can support.

	~~== Configuring 'ricci_pw.txt' ==~~

	In order for ''AN!CDB'' to add or remove servers, it must be able to authenticate against the cluster stack. The cluster stack has [[2-Node_Red_Hat_KVM_Cluster_Tutorial#Setting_Up_ricci\|it's own password]] for this purpose. This password is set by assigning a password to each node's <span class="code">ricci</span> system account.

	The dashboard keeps these passwords separate from the general ''Anvil!'' configuration found in <span class="code">an.conf</span>. These passwords instead are saved in <span class="code">/var/www/home/ricci_pw.txt</span>.

	This configuration file is much more simple to configure. You need to set the variable name to the cluster name that you set in <span class="code">an.conf</span>'s <span class="code">cluster::X::name</span> value. The password for that ''Anvil!'' is on the right, separated by an <span class="code">=</span> sign.

	So continuing our example above, the ''Anvil!'''s <span class="code">cluster</span> name was <span class="code">an-cluster-05</span>. The <span class="code">ricci</span> password on this ''Anvil!'' is <span class="code">secret</span>. So the <span class="code">ricci_pw.txt</span> entry would be:

	~~<syntaxhighlight lang="text">~~
	~~an-cluster-05 = "secret"~~
	~~</syntaxhighlight>~~

	Note that simple passwords do not need to be in double-quotes. However, if your password is complex and has special characters or spaces, the double-quotes ''are'' needed to ensure that the password is parsed properly.

	~~You can put as many ''Anvil!'' entries in this file as you wish. Simply ensure that each entry is on it's own line.~~
