修改/boot/grub/menu.lst檔案：
將 default=1 改為 default=0：
# cat /boot/grub/menu.lst
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.

MOSIX CONFIGURATION
===================

If this is your cluster's file-server and you want to configure MOSIX
for a set of nodes with a common root, please type their common root
directory. Otherwise, if you want to configure the node that you are
running on, just press :-

What would you like to configure?
=================================
1. Which nodes are in this cluster      (ESSENTIAL)
2. Authentication                       (ESSENTIAL)
3. Logical node numbering               (recommended)
4. Queueing policies                    (recommended)
5. Freezing policies
6. Miscellaneous policies
7. Become part of a multi-cluster organizational Grid

Configure what :- 1

There are no nodes in your cluster yet:
=======================================

To add a new set of nodes to your cluster, type 'n'.
To turn on advanced options, type '+'.
For help, type 'h'.
To save and exit, type 'q'.  (to abandon all changes and exit, type 'Q')

Option :- n                                     <==新增節點

Adding new node(s) to the cluster:

First host-name or IP address :- 192.168.74.141    <==節點ip
Number of nodes :- 1                            <==節點數

Nodes in your cluster:
======================
1. 192.168.74.141

To add a new set of nodes to your cluster, type 'n'.
To modify an entry, type its number.
To delete an entry, type 'd' followed by that entry-number (eg. d1).
To turn on advanced options, type '+'.
For help, type 'h'.
To save and exit, type 'q'.  (to abandon all changes and exit, type 'Q')

Option :- n                                     <==新增節點

Adding new node(s) to the cluster:

First host-name or IP address :- 192.168.74.147    <==節點ip
Number of nodes :- 1                            <==節點數

Nodes in your cluster:
======================
1. 192.168.74.141
2. 192.168.74.147

To add a new set of nodes to your cluster, type 'n'.
To modify an entry, type its number.
To delete an entry, type 'd' followed by that entry-number (eg. d2).
To turn on advanced options, type '+'.
For help, type 'h'.
To save and exit, type 'q'.  (to abandon all changes and exit, type 'Q')

Option :- q                                     <==儲存退出

Cluster configuration was saved.


OK to also update the logical node numbers [Y/n]? y

Suggesting to assign '192.168.1.5'
as the central queue manager for the cluster
(but be cautious if you mix 32-bit and 64-bit nodes in the same cluster)
OK to update it now [Y/n]? 

What would you like to configure next?
======================================
1. Which nodes are in this cluster
2. Authentication                       (ESSENTIAL)
3. Logical node numbering
4. Queueing policies
5. Freezing policies
6. Miscellaneous policies
7. Become part of a multi-cluster organizational Grid
q. Exit

Configure what :- 2                             <==設定密碼

MOSIX Authentication:
=====================

To protect your MOSIX cluster from abuse, preventing unauthorized
persons from gaining control over your computers, you need to set
up a secret cluster-protection key. This key can include any
characters, but must be identical throughout your cluster.

Your secret cluster-protection key: xxxx            <==輸入密碼
Your key is 5 characters long.
(in the future, please consider a longer one)

To allow your users to send batch-jobs to other nodes in the cluster,
you must set up a secret batch-client key. This key can include any
characters, but must match the 'batch-server' key on the node(s) that
can receive batch-jobs from this node.

Your secret batch-client key: xxxx                  <==輸入密碼
Your key is 5 characters long.
(in the future, please consider a longer one)

For this node to accept batch jobs,
you must set up a secret batch-server key. This key can include any
characters, but must match the 'batch-client' key on the sending nodes.

To make your batch-server key the same as your batch-client key, type '+'.
Your secret batch-server key: xxxx                  <==輸入密碼
Your key is 5 characters long.
(in the future, please consider a longer one)
