rhel6.4网络安装kvm虚拟机-蒲公英云

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=00295A: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）
