Xcat Deploy physical machine operating system (new)

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: 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

Configure password

You can use "Tabdump passwd" to view

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

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  xcat.xcatdomain

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. Configuring DNS

Makedns-n  
Service named restart  

Configure DHCP

Makedhcp-n

If the DHCP service does not start at this time, editing the/ETC/INIT.D/DHCPD file will

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

Then restart the DHCPD service

/ETC/INIT.D/DHCPD restart  

To 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  
copycds/appstore/iso/ Rhel-server-6.5-x86_64-dvd.iso

When you are finished adding, you can use the following command to view

Lsdef-t Osdistro
lsdef-t osimage

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  

Then run the following command

Makehosts xcat1
makedhcp xcat1

setting up a deployment system

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

Because the virtual machine is used for testing and there is no IPMI capability, we can only manually start the XCAT1 machine, and then we will find XCAT1 into the automatic installation system.

If you have a physical machine that supports IPMI functionality, you can refer to another blog post I sent earlier
XCAT installs the operating system via IPMI remote deployment
