PXE unattended installation CentOS system
PXE unattended installation of Linux system, can be multiple machines at the same time automatic operation management, reduce the workload of administrators, but also make management more scientific and effective. Therefore, PXE unattended installation of Linux is of great significance for administrators. Below, let's introduce a simple PXE process.
To establish a disc mount point
Mkdir/mnt/cdrom
Mount/dev/cdrom/mnt/cdrom
Access the CD server directory and install the VSFTPD service
cd/mnt/cdrom/server/
RPM-IVH vsftpd-2.0.5-16.e15.i386.rpm
Start VSFTPD
Service VSFTPD Start
Set VSFTPD to boot automatically
Chkconfig vsftpd on
Installing the DHCP service
RPM-IVH dhcp-3.0.5-21.e15.i386.rpm
Start the DHCP service
However, there are no configuration scripts currently, so edit the configuration script first
Enter script editing interface
Vi/etc/dhcpd.conf
Enter: Set Nu to display line numbers
R/usr/share/doc/dhcp-3.0.5/dhcp.conf.sample in bottom row mode (read Dhcp.conf.sample file)
After modification
Note: The main modification is subnet to local network segment, the default gateway option Routers,option Subnet-mask,optiondomain-name-servers, other can not be tube.
Now DHCP can start ...
Service DHCPD Start
Set up the DHCP service to boot from
Install the TFTP server below
Check to see if it has been installed before
Rpm-qa |grep TFTP
I've already installed it here, and if it's not installed, perform the following instruction installation
RPM-IVH tftp-server-0.49-2.i386.rpm
View the installation directory
RPM-QL Tftp-server
By/ETC/XINETD.D/TFTP, the TFTP service is under the control of the Super daemon.
So set up the boot from
Edit/etc/xinetd.d/ftp
Vi/etc/xinetd.d/ftp
Just change the Disable =yes to No (wake not wake)
TFTP boot from boot setup complete: Wq Save exit
Reboot the Super daemon, otherwise it will not take effect ...
Service xinetd Restart
Since then, three servers have been built, but the FTP server is more special, you need to place a CD-ROM image files, then I will copy the CD file up ...
Return to the disc root directory,
Cd..
Copy the files on the CD to. var/ftp/pub/
Cp-r (there is a directory in the disc, to use recursive parameters). (. Represents all under the disc root)/var/ftp/pub/
After the copy of the CD file, all the features of FTP are
I got an address on FTP, but how do I know Tftp-server's address?
Edit Dhcp.config File
