Do you wish to have Perceus do a complete system initialization (yes/no)? yes
What IP address should the node boot address range start at?
(192.168.10.192)> 10.0.0.21
What IP address should the node boot address range end at?
(192.168.10.254)> 10.0.0.22
What domain name should be appended to the DNS records for each entry in DNS?
This won't require you to specify the domain for DNS lookups, but it prevents
conflicts from other non-local hostnames.

What device should the booting node direct its console output to? Typically
this would be set to 'tty0' unless you are monitoring your nodes over the
serial port. A typical serial port option might be 'ttyS0,115200'.
note: This is a global option which will affect all booting nodes.

Creating Perceus ssh keys
Generating public/private dsa key pair.
Your identification has been saved in /root/.ssh/perceus.
Your public key has been saved in /root/.ssh/perceus.pub.
The key fingerprint is:

Jumping into automatic Perceus registration...
Perceus registration:
Here we will ask several basic questions about you (the user) that will be
sent to the developers of Perceus.
The following questions will only take a moment, and are very helpful
to the developers of this software and will never be shared or sold:
(1/6) Name: Jason Tang
(2/6) Email address: Email住址會使用灌水程式保護機制。你需要啟動Javascript才能觀看它
(3/6) Company name: LTD
(4/6) Your role: IT
(5/6) Node Count: 00852
(6/6) Comments: Testing
Registration successful!

Mounting VNFS 'centos-6-1.x86_64'...
The VNFS can be found at: /mnt/centos-6-1.x86_64
================================================================================
VNFS Capsule root password:
Here you will need to set the root password for this VNFS capsule. This password
will be used to gain local access to the node and potentially for ssh access if
for some reason the automatic Perceus ssh keys are not used.
It is not recommended to make this password the same as the master node because
depending on your configuration, it maybe possible for a non-administrative user
to download the VNFS image and extract the password. Best practice to not use a
critical or shared password for your VNFS capsules.
Changing password for user root.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.
Press [ENTER] to continue:
================================================================================
Enable NFS based file system hybridization:
This VNFS is capable of hybridizing parts of the node file system to a network
based file system (e.g. NFS) through the use of symbolic links. To do this
requires an entry in the nodes /etc/fstab which will mount the file system
which will provide the targets to the symbolic links.
In its default configuration this network mount is not required for node
operation (this can be changed in the "hybridized" VNFS configuration file) but
it is useful for making the node feel more like a traditionally installed
operating system without utilizing more RAM.
Do you wish to enable NFS based hybridization support? (Default is 'yes')
Hybridization Support [yes]>
Creating fstab entry for hybrid NFS requirements
Will mount: 10.0.0.20:/var/lib/perceus/
================================================================================
Default console device:
The default console is where the kernel and boot messages are displayed. Usually
this is set to 'tty0' which is the traditional default video and keyboard
device. You can also set it to a serial device (e.g. 'ttyS0' or 'ttyS1' for COM1
and COM2 respectively).
If you are unsure which console device you wish to make default, just press
[ENTER] to accept the default ('tty0').
Console Device [tty0]>
Setting default console to: tty0
================================================================================
Various Network Service Configurations:
Next you will be prompted for configurations of various services within this
VNFS capsule.
The Perceus services by default will manage DNS, so under almost all
circumstances you should assign this to the Perceus master server.
Enter the IP address of the DNS server [10.0.0.20]>
Enter the IP address of your NTP master [10.0.0.20]>
================================================================================
Finalizing VNFS configuration:
Copying master's timezone configuration
Copying ssh public keys
Updating hosts file
Copying ssh host keys from /etc/perceus/keys/
================================================================================
VNFS Configuration Complete
Un-mounting VNFS 'centos-6-1.x86_64'...
This will take some time as the image is updated and compressed...
VNFS 'centos-6-1.x86_64' has been successfully imported.
perceus node set vnfs centos-6-1.x86_64 node0001
Hostname Group NodeID
-------------------------------------------------------------------------------
node0001 cluster 00:0C:29:F7:B4:44
Are you sure you wish to set 'vnfs=centos-6-1.x86_64' on 1 nodes?
Please Confirm [yes/no]> yes
'1' nodes set vnfs='centos-6-1.x86_64'
perceus node set vnfs centos-6-1.x86_64 node0002
Hostname Group NodeID
-------------------------------------------------------------------------------
node0002 cluster 00:0C:29:B0:7B:7A
Are you sure you wish to set 'vnfs=centos-6-1.x86_64' on 1 nodes?
Please Confirm [yes/no]> yes
'1' nodes set vnfs='centos-6-1.x86_64'
reboot
You could also add the capsule to the default VNFS assignment in /etc/perceus/defaults.conf.
Powering on nodes connected to the Perceus master network will now provision them with the assigned VNFS capsule. If you need to alter the VNFS capsule, mount it with:
# perceus vnfs mount centos-6-1.x86_64
Chroot to the mounted directory and make changes, or use 'yum --installroot' or 'rpm --root' flags to install binaries. When finished finalize changes and recompress the VNFS capsule:
# perceus vnfs umount centos-6-1.x86_64
