Use PXE + DHCP + TFTP + APACHE to automatically install LINUX instances in VM

Test preparation: One Installation server (CentOS5.5 under the vm) will use the following kits on the Installation server: dhcp, tftp, httpd first: is set on the Installation server [root @ localhost ~] # Yum-yinstalltftp-serverdhcphttpd check installation kits [root @ localhost ~] # Vie

Lab preparation: One Installation server (CentOS5.5 under the vm)

 

The kit used on the Installation server is dh.Cp, TFtp,Httpd

First, it is the settings on the Installation server.

[Root @ localhost ~] # Yum-y installTftp-Server dhcp httpd // check installation kits

[Root @ localhost ~] # Vi/etc/dhcpd. conf // configure dhcpd

DdNs-upDate-Style interim;

Ignore client-updates;

 

SuBnet 192.168.1.0 netmask 255.255.255.0 {

 

# --- Default gateway

Option routers 192.168.1.1; // GATEWAY

Option subnet-mask limit 255.0; // NETMASK

 

Option nis-domain "domain.org ";

Option domain-name "domain.org ";

Option domain-name-servers 202.102.240.65; // DNS-server-IP

 

OptionTime-OffSet-18000; # Eastern Standard Time

 

Range dynamic-bootp 192.168.1.128 192.168.1.254;

Default-lease-time 21600;

Max-lease-time 43200;

 

NExT-server 192.168.1.193; // This is the IP address of the server to be installed.

FileName "/pxelinux.0 ";

}

The next step is to configure the automatic installation options. If you prefer to manually configure the System Options (that is, the normal installation steps), the next step may not be used.

Then Configure NFS (that is, set the installation tree)

[Root @ localhost ~] # Mount-o loop/dev/hdc/mnt/iso/

[Root @ localhost ~] # Vi/etc/ExportS

/Mnt/iso * (ro)

[Root @ localhost ~] #/Etc/init. d/portmap restart

[Root @ localhost ~] #/Etc/init. d/nfs restart

[Root @ localhost ~] # Exportfs-arv

Exporting *:/mnt/iso

Set TFTP (in fact, it is enough to open it)

[Root @ localhost ~] # Vi/etc/xinetd. d/tftp

Service tftp

{

Socket_type = dgram

ProtoCol= Udp

Wait = yes

User = root

Server =/usr/sbin/in. tftpd

Server_args =-s/tftpboot

Disable = no

Per_source = 11

CPIs = 100 2

Flags = IPv4

}

 

Then configure PXE.

[Root @ localhost/] # cp/usr/lib/syslinux/pxelinux.0/tftpboot/

[Root @ localhost/] # mount-o loop/dev/hdc/mnt/iso

[Root @ localhost/] # cp/mnt/iso/images/pxeboot/{initrd. img, vmlinuz}/tftpboot/

[Root @ localhost/] # cp/mnt/iso/isolinux/*. msg/tftpboot/
