Xcat Deploy physical machine operating system

First we assume that the two machines, the machine name and the IP address are as follows

Xcat Master
    hostname:xcat
    ip:192.168.31.102
xcat node
    hostname:xcat1
    ip:192.168.31.251

The specific steps are as follows:

1. Create a local operating system installation file

Copycds-n centos5.11-a x86_64 centos-5.11-x86_64-bin-dvd-1of2.iso centos-5.11-x86_64-bin-dvd-2of2.iso
Copycds- n centos6.6-a x86_64 Centos-6.6-x86_64-bin-dvd1.iso Centos-6.6-x86_64-bin-dvd2.iso

2. Configure Xcat Basic information

Chtab key=master site.value=192.168.31.102
chtab key=domain # Depending on the circumstances, this attribute is eventually written to each node's/ The
chtab key=nameservers site.value=192.168.31.102 # in the etc/resolv.conf file is configured according to the circumstances, and this attribute is eventually written to the/etc/of each node resolv.conf file
chtab key=forwarders site.value=192.168.31.1

In addition, use the "tabdump Networks" command to check if the networks table information is consistent with the above site table information, if inconsistent can be modified using the following command

Chtab netname=192_168_31_0-255_255_255_0 \
	networks.net=192.168.31.0 \
	networks.mask=255.255.255.0 \
	networks.gateway=192.168.31.1 \
	networks.dhcpserver=192.168.31.102 \
	networks.tftpserver=192.168.31.102 \
	networks.nameservers=192.168.31.102 \
	networks.ntpservers=192.168.31.102

3. Configure password, you can use "Tabdump passwd" to view

Chtab Key=system Passwd.username=root Passwd.password=letmein

4. Configuring nodes

Nodeadd xcat1 \
    groups=compute,all \
    mac.interface=eth0 \
    mac.mac=08:00:27:2c:30:8c \
    hosts.ip= 192.168.31.251 \
    noderes.netboot=pxe \
    noderes.xcatmaster=192.168.31.102 \
    noderes.installnic=eth0 \
    noderes.primarynic=eth0 \
    noderes.nfsserver=192.168.31.102 \
    nodetype.os=centos6.6
    \ nodetype.arch=x86_64 \
    nodetype.profile=compute \
    Nodetype.nodetype=osi

You can use the following command to view various information when you have finished adding

Tabdump nodelist
tabdump nodetype tabdump noderes-tabdump
mac Tabdump
hosts

5. Configure Host

Makehosts

The contents of the/etc/hosts file after configuration are roughly as follows

127.0.0.1 localhost
192.168.31.102 xcat

* Note that Xcat Master must be configured because the MAKEDNS command requires that the admin node be part of domain, so if you do not need to add it manually.

6. Configure DNS

Makedns-n
Service named restart

7. Configure DHCP

Makedhcp-n

* Edit the/ETC/INIT.D/DHCPD file to

USER=DHCPD
GROUP=DHCPD
changed to
user=root
group=root

Then restart the DHCPD service

/ETC/INIT.D/DHCPD restart

8. Set up Deployment system

NodeSet XCAT1 Osimage=centos5.11-x86_64-install-compute

You can see output similar to the following, indicating that the XCAT1 machine will install Centos6.6-x86_64-compute

Xcat1:install Centos6.6-x86_64-compute

If we need to modify the installed system, we can use the following command to modify the

Chtab node=xcat1 \
    nodetype.os=centos5.11 \
    nodetype.arch=x86_64 \
    nodetype.profile=compute \
    Nodetype.nodetype=osi
nodeset xcat1 Install

At this point you can see that the XCAT1 machine will be installed Centos5.11-x86_64-compute

Xcat1:install Centos5.11-x86_64-compute

9. With the use of virtual machines for testing and no IPMI capabilities, we can only manually start the XCAT1 machine, and then we will find XCAT1 into the automated installation system.
