corosync-keygen
COROSYNC-KEYGEN(8) System Manager's Manual COROSYNC-KEYGEN(8)NAME
corosync-keygen - Generate an authentication key for Corosync.
SYNOPSIS
corosync-keygen [-l]
DESCRIPTION
If you want to configure corosync to use cryptographic techniques to ensure authenticity
and privacy of the messages, you will need to generate a private key.
corosync-keygen creates this key and writes it to /etc/corosync/authkey.
This private key must be copied to every processor in the cluster. If the
private key isn't the same for every node, those nodes with nonmatching private
keys will not be able to join the same configuration.
Copy the key to some security transportable storage or use ssh to transmit the
key from node to node. Then install the key with the command:
unix#: install -D --group=0 --owner=0 --mode=0400 /path_to_authkey/authkey /etc/corosync/authkey
If a message "Invalid digest" appears from the corosync executive, the keys
are not consistent between processors.
Note: corosync-keygen will ask for user input to assist in generating entropy unless the -l option is used.
OPTIONS -l Use a less secure random data source that will not require user input to help generate
entropy. This may be useful when this utility is used from a script.
EXAMPLES
Generate the key.
$ corosync-keygen
Corosync Cluster Engine Authentication key generator.
Gathering 1024 bits for key from /dev/random.
Press keys on your keyboard to generate entropy.
