Update apt-get source and install required software
Sudo apt-get install syslinux dnsmasq apache2

Configure dnsmasq
Sudo vim/etc/dnsmasq. conf
Remove the # Above the following items
Bogus-priv
Filterwin2k
Interface = eth0
Dhcp-range = 192.168.44.100, 192.168.44.120, 12 h
Dhcp-boot = pxelinux.0
Enable-tftp
Tftp-root =/var/ftpd
Dhcp-authoritative

The eth0 following the interface indicates listening to this network card. If you want all network cards connected to the network to be served, comment out this line.

Copy the files required to install CentOS6
Sudo mkdir-p/var/www/centos6/mnt/cd/var/ftpd/pxelinux. cfg
Sudo mount-o loop-t auto ~ /Iso/CentOS-6.2-x86_64-bin-DVD1.iso/mnt/cd
Sudo cp-rv/mnt/cd/*/var/www/centos6
Sudo cp-rv/mnt/cd/isolinux/*/var/ftpd
Sudo cp/usr/lib/syslinux/pxelinux.0/var/ftpd
Sudo mv/var/ftpd/isolinux. cfg/var/ftpd/pxelinux. cfg/default
To deploy ttuserver12, you also need to mount the image and copy all the files to the http directory, such as/var/www/Ubuntuserver12. However, the following steps are not required, the following isolinux is started by creating pxe, and one copy is enough.

Ubuntu server installation may prompt http: // 192.168.44.249/effectuserver12/dists/precise/restricted/binary-amd64/Packages was too upt. This is a bug
The solution is to directly touch an empty file.
Sudo touch/var/www/ubuntu/dists/precise/restricted/binary-amd64/Packages
Precise is the version code of ubuntu12.04.4. If it is another version, replace it with the corresponding code.

Modify the pxe Startup Menu
Sudo vim/var/ftpd/pxelinux. cfg/default
Append ks = http: // 192.168.44.249/centos6/ks. cfg initrd = initrd. img

If you have other systems, you can add them by yourself. You can locate the kernel and initrd accurately.

Restart dnsmasq
Sudo service dnsmasq restart

If ubuntu is installed, there are two differences: 1 is the ks file is slightly different; 2 is the default file of the boot menu after pxe is started, must use the centos style, otherwise, the kernel and initialization environment cannot be found. Ubuntu's default file must be integrated with the txt. cfg file, and the ui and include lines should be commented out (personal opinion)
