The test environment 1 shows

I. Prerequisites for installation:

1. Make sure the motherboard supports intel-VT or AMD-V

2. rhel 6.4 in VMware has been installed and the virtual machine has been set to support virtualization. The settings are as follows:

3. Confirm whether intel-VT or AMD-V is supported by command

[Root @ localhost ~] # Egrep -- color "vmx | svm"/proc/cpuinfo

If a result is returned, it is supported, and vice versa.

2. Install KVM and configure Nic bridging (bridge to eth1), and operate on the installed rhel 6.4 (shown in Figure 1 ).

1. Install KVM

[Root @ localhost ~] # Yum-y groupinstall Virtualization "Virtualization Client" "Virtualization Platform" "Virtualization Tools"

[Root @ localhost ~] #/Etc/init. d/lib1_d start; chkconfig lib1_d on

[Root @ localhost ~] #/Etc/init. d/libvirt-guests start; chkconfig libvirt-guests on

2. Bridge settings

[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 // Add this line

[Root @ localhost network-scripts] # pwd

/Etc/sysconfig/network-scripts

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

# Cat ifcfg-br0 [root @ localhost network-scripts] #

DEVICE = br0 // DEVICE name br0

TYPE = Bridge // set the TYPE to Bridge

ONBOOT = yes

NM_CONTROLLED = no

BOOTPROTO = static

IPADDR = 172.16.1.1

NETMASK = 255.255.255.0

Restart the network

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

View Bridge Information

[Root @ localhost network-scripts] # brctl show

Bridge name bridge id STP enabled interfaces

Br0 8000.000c293f5a2e no eth1 // the device has been mounted to eth1.

Virbr0 8000.525400635d23 yes virbr0-nic

Iii. Configure dhcp + tftp + vsftpd to install the server

◆. Install dhcp

1. [root @ localhost ~] # Yum-y install dhcp

2. Configure 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. Start the dhcp service

[Root @ localhost ~] #/Etc/init. d/dhcpd start; chkconfig dhcpd on

Starting dhcpd: [OK]

[Root @ localhost ~] #

◆. Install tftp-server and syslinux

1. [root @ localhost ~] # Yum-y install tftp-server syslinux

2. Configure 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 // change yes to no

Per_source = 11

CPIs = 100 2

Flags = IPv4

}
