rhel6.4網(wǎng)絡(luò)安裝kvm虛擬機

來源：程序員人生發(fā)布時間：2014-12-16 08:51:59 閱讀次數(shù)：3235次

本次實驗環(huán)境如圖1所示

1：安裝條件條件：

1.確保主板支持intel-VT或AMD-V

2.VMware里的rhel 6.4已裝好，并且已設(shè)置該虛擬機也支持虛擬化，設(shè)置以下所示

3.通過命令確認(rèn)是不是支持intel-VT或AMD-V

[root@localhost ~]# egrep --color "vmx|svm" /proc/cpuinfo

有結(jié)果返回就說明支持，反之亦然

2：安裝KVM并配置網(wǎng)卡橋接(橋接到eth1上)，在已安裝的rhel 6.4 （圖 1所示）上操作

1.安裝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.網(wǎng)橋設(shè)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 //添加這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 //裝備名為br0

TYPE=Bridge //設(shè)別類型為Bridge

ONBOOT=yes

NM_CONTROLLED=no

BOOTPROTO=static

IPADDR=172.16.1.1

NETMASK=255.255.255.0

重啟網(wǎng)絡(luò)

[root@localhost network-scripts]#/etc/init.d/network restart

查看網(wǎng)橋信息

[root@localhost network-scripts]# brctl show

bridge name bridge id STP enabled interfaces

br0 8000.000c293f5a2e no eth1 //已橋接到eth1上

virbr0 8000.525400635d23 yes virbr0-nic

3：配置dhcp+tftp+vsftpd網(wǎng)絡(luò)安裝服務(wù)器

◆.安裝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.啟動dhcp服務(wù)

[root@localhost ~]# /etc/init.d/dhcpd start;chkconfig dhcpd on

Starting dhcpd: [ OK ]

[root@localhost ~]#

◆.安裝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為光盤掛載目錄

[root@localhost tftpboot]# cp isolinux.cfg pxelinux.cfg/default

[root@localhost tftpboot]# chmod 644 pxelinux.cfg/default

[root@localhost tftpboot]# vi pxelinux.cfg/default （其中紅色為更改處）

default linux
