Configuració

/etc/clusters

El fitxer /etc/clusters és el fitxer principal de configuració de cssh, conté la configuració del sistema.

NOTA: També es pot fer una configuració per user editant el fitxer ~/.csshrc. El format del fitxer és el mateix en tots dos casos

El primer que cal fer és definir un cluster:

clusters = cluster1

NOTA: Es poden definir múltiples clusters

Ara cal definir les màquines que formen part del cluster:

cluster1 = test1 test2

By calling out the "all" cluster as containing cluster1 and cluster2, if either of those clusters ever change, the change is automatically captured so you don't have to update the "all" definition. This will save you time and headache if your .csshrc file ever grows in size.

App-ClusterSSH

The is the Perl application bundle for ClusterSSH (a.k.a cssh), formally
a GNU tools based project.

ClusterSSH is a tool for making the same change on multiple servers at
the same time.  The 'cssh' command opens an administration console and
an xterm to all specified hosts.  Any text typed into the administration
console is replicated to all windows.  All windows may also be typed into
directly.

This tool is intended for (but not limited to) cluster administration
where the same configuration or commands must be run on each node
within the cluster.  Performing these commands all at once via this
tool ensures all nodes are kept in sync.
