rhel6.4网络安装kvm虚拟机

ゝ一世哀愁。 2022-08-05 20:59 223阅读 0赞

本次试验环境如图1所示

![Center][]

一：安装前提条件：

1.确保主板支持intel-VT或AMD-V

2.VMware里的rhel 6.4已经装好，并且已设置该虚拟机也支持虚拟化，设置如下所示

![Center 1][]

3.通过命令确认是否支持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

二：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                                                                                      //添加这一行

\[root@localhost network-scripts\]\# pwd

/etc/sysconfig/network-scripts

\[root@localhost network-scripts\]\# cp ifcfg-eth1 ifcfg-br0

\[root@localhost network-scripts\]\# cat ifcfg-br0

DEVICE=br0                                                                                       //设备名为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

三：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改为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）
