                首先我們假定兩臺機器,機器名和ip地址分別如下 xcat masterhostname: xcatip: 192.168.31.102xcat nodehostname: xcat1ip: 192.168.31.251 具體操作步驟如下: ### 配置xCAT基本信息 ~~~ chtab key=master site.value=192.168.31.102 chtab key=domain site.value=xcatdomain # 根據具體情況配置,這個屬性最后會被寫到每個node的/etc/resolv.conf文件里 chtab key=nameservers site.value=192.168.31.102 # 根據具體情況配置,這個屬性最后會被寫到每個node的/etc/resolv.conf文件里 chtab key=forwarders site.value=192.168.31.1 ~~~ 另外用”tabdump networks”命令來檢查一下networks表信息是否和上面site表的信息一致,如果不一致可以使用下面的命令修改 ~~~ 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 ~~~ ### 配置Password 可以使用“tabdump passwd”查看 ~~~ chtab key=system passwd.username=root passwd.password=Letmein ~~~ ### 配置Host ~~~ makehosts ~~~ 配置后/etc/hosts文件內容大致如下 ~~~ 127.0.0.1 localhost 192.168.31.102 xcat xcat.xcatdomain ~~~ - 注意xcat master必須配置進去,因為 makedns 命令要求管理節點必須是domain的一部分,所以如果沒有需要手動添加。 ### 配置DNS ~~~ makedns -n service named restart ~~~ ### 配置DHCP ~~~ makedhcp -n ~~~ - 如果此時dhcp服務不能啟動,編輯/etc/init.d/dhcpd文件,將 ~~~ user=dhcpd group=dhcpd 改為 user=root group=root ~~~ 然后重新啟動dhcpd服務 ~~~ /etc/init.d/dhcpd restart ~~~ ### 創建本地操作系統安裝文件 ~~~ 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 ~~~ 添加完成后可以使用下面命令來查看 ~~~ lsdef -t osdistro lsdef -t osimage ~~~ ### 配置節點 ~~~ 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 ~~~ 添加完成后可以使用下面的命令來查看各種信息 ~~~ tabdump nodelist tabdump nodetype tabdump noderes tabdump mac tabdump hosts ~~~ 然后運行下面命令 ~~~ makehosts xcat1 makedhcp xcat1 ~~~ ### 設置部署系統 ~~~ nodeset xcat1 osimage=centos5.11-x86_64-install-compute ~~~ 由于使用的是虛擬機做測試,沒有IPMI功能,所以我們只能手動啟動xcat1機器,然后就會發現xcat1進入自動安裝系統了。 如果有物理機支持IPMI功能,可以參考我前面發的另一篇博客 [xCAT 通過 IPMI 遠程部署安裝操作系統](http://blog.csdn.net/kongxx/article/details/44181711) 轉載請以鏈接形式標明本文地址 本文地址:[http://blog.csdn.net/kongxx/article/details/44572255](http://blog.csdn.net/kongxx/article/details/44572255)
