corosync-qnetd-certutil - tool to generate qnetd TLS certificates
corosync-qnetd-certutil [-i|-s] [-c certificate] [-n cluster_name]
corosync-qnetd-certutil is a frontend for the NSS certutil, it is used
for generating the QNetd CA (Certificate Authority), server certificate and
signing cluster certificate used by
corosync-qdevice when using the
model 'net'.
- -i
- Initialize the QNetd NSS certificate database and generate
the QNetd CA and server certificates. The default directory for the
database is /etc/corosync/qnetd. This directory must be writeable by the
current user. The QNetd CA certificate is also exported into the file
/etc/corosync/qnetd/nssdb/qnetd-cacert.crt.
- -s
- Sign the cluster certificate. It is necessary to pass the
cluster name (as configured in corosync.conf) and the certificate request
file - see options below. The signed certificate will be written to the
file /etc/corosync/qnetd/nssdb/cluster-$ClusterName.crt
- -c
- Certificate request file to sign.
- -G
- Do not set group write bit for new files. This option has
effect only when used together with -i option. It is useful when
extended security is needed and it's viable to prohibit daemon to change
its configuration. Expected usage is to first set owner of the
/etc/corosync/qnetd directory to root:$COROQNETD with permissions 0750 and
then create database (as a root):
# corosync-qnetd-certutil -i -G
- -n
- Name of the cluster.
If qnetd is executed by a non root user, /etc/corosync/qnetd and its
subdirectories must be owned by (or have group access for) the given user. If
corosync-qnetd-certutil is executed as root it tries to copy the owner
and group of /etc/corosync/qnetd to all of the created files.
