来源:程序员人生 发布时间:2014-12-16 08:51:59 阅读次数:3071次
本次实验环境如图1所示
1:安装条件条件:
1.确保主板支持intel-VT或AMD-V
2.VMware里的rhel 6.4已装好,并且已设置该虚拟机也支持虚拟化,设置以下所示
3.通过命令确认是不是支持intel-VT或AMD-V
[root@localhost ~]# egrep --color "vmx|svm" /proc/cpuinfo
有结果返回就说明支持,反之亦然
2:安装KVM并配置网卡桥接(桥接到eth1上),在已安装的rhel 6.4 (图 1所示)上操作
1.安装KVM
[root@localhost ~]#yum -y groupinstall Virtualization "Virtualization Client" "Virtualization Platform" "Virtualization Tools"
[root@localhost ~]# /etc/init.d/libvirtd start ; chkconfig libvirtd on
[root@localhost ~]#/etc/init.d/libvirt-guests start ; chkconfig libvirt-guests on
2.网桥设置
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
HWADDR=00:0C:29:3F:5A:2e
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=172.16.1.1
NETMASK=255.255.255.0
BRIDGE=br0 //添加这1行
[root@localhost network-scripts]# pwd
/etc/sysconfig/network-scripts
[root@localhost network-scripts]# cp ifcfg-eth1 ifcfg-br0
[root@localhost network-scripts]# cat ifcfg-br0
DEVICE=br0 //装备名为br0
TYPE=Bridge //设别类型为Bridge
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=172.16.1.1
NETMASK=255.255.255.0
重启网络
[root@localhost network-scripts]#/etc/init.d/network restart
查看网桥信息
[root@localhost network-scripts]# brctl show
bridge name bridge id STP enabled interfaces
br0 8000.000c293f5a2e no eth1 //已桥接到eth1上
virbr0 8000.525400635d23 yes virbr0-nic
3:配置dhcp+tftp+vsftpd网络安装服务器
◆.安装dhcp
1.[root@localhost ~]# yum -y install dhcp
2.配置dhcp
[root@localhost ~]# grep -v "^#"/etc/dhcp/dhcpd.conf |grep ^[^$]
default-lease-time 600;
max-lease-time 7200;
next-server 172.16.1.1;
filename "pxelinux.0";
ddns-update-style none;
log-facility local7;
subnet 172.16.1.0 netmask 255.255.255.0 {
range 172.16.1.2 172.16.1.10;
}
[root@localhost ~]#
3.启动dhcp服务
[root@localhost ~]# /etc/init.d/dhcpd start;chkconfig dhcpd on
Starting dhcpd: [ OK ]
[root@localhost ~]#
◆.安装tftp-server和syslinux
1.[root@localhost ~]# yum -y install tftp-server syslinux
2.配置tftp
[root@localhost ~]# grep -v "^#"/etc/xinetd.d/tftp
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server =/usr/sbin/in.tftpd
server_args = -s/var/lib/tftpboot
disable = no //把yes改成no
per_source = 11
cps = 100 2
flags = IPv4
}
[root@localhost tftpboot]# pwd
/var/lib/tftpboot
[root@localhost tftpboot]# cp /usr/share/syslinux/pxelinux.0 ./
[root@localhost tftpboot]# mkdir pxelinux.cfg
[root@localhost tftpboot]# cp /media/rhel/isolinux/* ./ ///media/rhel为光盘挂载目录
[root@localhost tftpboot]# cp isolinux.cfg pxelinux.cfg/default
[root@localhost tftpboot]# chmod 644 pxelinux.cfg/default
[root@localhost tftpboot]# vi pxelinux.cfg/default (其中红色为更改处)

3.启动xinentd服务
[root@localhost ~]# /etc/init.d/xinetd start ; chkconfig xinetd on
Starting xinetd: [ OK ]
[root@localhost ~]#
◆安装vsftpd
1. [root@localhost ~]# yum -y install vsftpd
2.启动vsftpd服务
[root@localhost ~]# /etc/init.d/vsftpd start ; chkconfig vsftpd on
Starting vsftpd for vsftpd: [ OK ]
[root@localhost ~]#
3.挂载安装光盘到ftp目录下
[root@localhost ~]# mount /dev/cdrom/ var/ftp/pub/
◆配置ks文件
1.ks文件内容以下
[root@localhost ~]# cat rhel6.4.cfg
#platform=x86, AMD64, or Intel EM64T
#version=DEVEL
# Firewall configuration
firewall --disabled
# Install OS instead of upgrade

注:ks文件制作这里不做演示,我已提早做好
2.复制rhel6.4.cfg到/var/ftp/目录下
[root@localhost ~]# cp rhel6.4.cfg /var/ftp/
4:开始安装虚拟机,virt-manager图形界面安装在这里不做演示,这里只演示通过ks文件安装
1.location+"extra-args"方式安装
[root@localhost ~]# virt-install
> --name rhel6.4⑴
> --ram 1024
> --vcpus 1
> --os-type=linux //可以不需要这句,只支持URL方式
> --os-variant=rhel6 //可以不需要这句,只支持URL方式
> --network bridge=br0
> --file /var/lib/libvirt/images/rhel6.4⑴.img
>--file-size 5
>--nonsparse
> --location ftp://172.16.1.1/pub/
> --extra-args "ks=ftp
