PXE Linux installed (multi-system installation)

PXE Server Batch Deployment
1. Unattended automatic Installation
2. Make LVM Manage disk
3, after the installation of the automatic initialization configuration
Service 176.20.32.208ls

# Yum-config-manager--add-repo ftp://176.20.32.208/rhel6 genetic a Yum source
# echo ' gpgcheck=0 ' >>/etc/yum.repos.d/176.20.32.208_rhel6.repo

I. Configuring DHCP (Dynamic Host Configuration Protocol)
DHCP Port number UDP67/68
The client sends the DHCPDISCOVER broadcast message, the server responds to the DHCPOFFER message, and the client returns
DHCPRequest message, the last service sends a DHCPACK message acknowledgment.

# yum-y Install DHCP
# cp/usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample/etc/dhcp/dhcpd.conf

# yum-y Install Tftp-server
# cd/var/lib/tftpboot/
# mkdir Pxelinux.cfg
# cp/var/ftp/rhel6/isolinux/*/var/lib/tftpboot/
Copy all files under the RHEL6 CD Isolinux directory to/var/lib/tftpboot/

V. Provision of RHEL7 system installation
# cd/var/lib/tftpboot/
# mkdir Rhel7
Copy the relevant text from the RHEL7 CD directory to the TFTP server
# cp/var/ftp/rhel7/images/pxeboot/*/var/lib/tftpboot/rhel7
# Vim Pxelinux.cfg/default

Lable rhel7.0
Menu lable Install ^rhel7
Kernel Rhel7/vmlinuz
Append initrd=rhel7/initrd.img ks=ftp://176.20.32.208/rhel7/rhel7.cfg repo=ftp://176.20.32.208/rhel7 ks.device= Bootif

Note: The Rhel7 KS file needs to be generated on the RHEL7 system, generated and placed into the 176.20.32.208 FTP server directory under RHEL7, named Rhel7.cfg

# service VSFTPD start; Chkconfig vsftpd on

Iv. Testing
Create a virtual machine to connect to the PRIVATE1 network
