Translating by GOLinux! Adding Ubuntu 14.10, Ubuntu 14.04 and Debian 7 to PXE Network Boot Environment Setup on RHEL/CentOS 7 ================================================================================ This tutorial will guide you on how to add **Ubuntu 14.10 Server, Ubuntu 14.04 Server** and **Debian 7 Wheezy** distributions to PXE Network Boot Environment Setup on **RHEL/CentOS 7**. ![Add Ubuntu and Debian to PXE Network](http://www.tecmint.com/wp-content/uploads/2014/11/Add-Ubuntu-and-Debian-to-PXE.png) Add Ubuntu and Debian to PXE Network Although for the purposes of this tutorial, I will only demonstrate how you can add **64-bit** Network Installation Images, the same procedure can also be applied for Ubuntu or Debian **32-bit** or other architectures images. Also, the process of adding Ubuntu 32-bit sources will be explained but not configured on my premises. Installing **Ubuntu** or **Debian** from a PXE Server requires that your client machines must have an active Internet connection, preferably configured through **NAT** with **DHCP** dynamic addresses allocation, in order for the installer to pull the required packages and finish the installation process. #### Requirements #### - [Install PXE Network Boot Server for Multiple Linux Distribution Installations in RHEL/CentOS 7][1] ## Step 1: Add Ubuntu 14.10 and Ubuntu 14.04 Server to PXE Menu ## **1.** Adding Network Installation Sources for **Ubuntu 14.10** and **Ubuntu 14.04** to PXE Menu can be achieved in two ways: One is by downloading the Ubuntu CD ISO Image and mount it on PXE Server machine in order to access Ubuntu Netboot files and the other is by directly downloading Ubuntu Netboot archive and extract it onto the system. Further I will discuss both methods: ### Using Ubuntu 14.10 and Ubuntu 14.04 CD ISO Image ### In order to use this method your PXE server needs a functional CD/DVD drive. On an arbitrary computer go to [Ubuntu 14.10 Download][2] and [Ubuntu 14.04 Download][3] page, grab the 64-bit **Server Install Image**, burn it to a CD, place the CD image to PXE Server DVD/CD drive and mount it on your system using the following command. # mount /dev/cdrom /mnt In case your PXE server machine has no CD/DVD drive you can download **Ubuntu 14.10** and **Ubuntu 14.04** ISO Image locally using **wget** command line and mount it on your server on the same above path by issuing the following commands (download and mount the CD). #### On Ubuntu 14.10 #### ------------------ On 32-Bit ------------------ # wget http://releases.ubuntu.com/14.10/ubuntu-14.10-server-i386.iso # mount -o loop /path/to/ubuntu-14.10-server-i386.iso /mnt ---------- ------------------ On 64-Bit ------------------ # wget http://releases.ubuntu.com/14.10/ubuntu-14.10-server-amd64.iso # mount -o loop /path/to/ubuntu-14.10-server-amd64.iso /mnt #### On Ubuntu 14.04 #### ------------------ On 32-Bit ------------------ # wget http://releases.ubuntu.com/14.04/ubuntu-14.04.1-server-i386.iso # mount -o loop /path/to/ubuntu-14.04.1-server-i386.iso /mnt ---------- ------------------ On 64-Bit ------------------ # wget http://releases.ubuntu.com/14.04/ubuntu-14.04.1-server-amd64.iso # mount -o loop /path/to/ubuntu-14.04.1-server-amd64.iso /mnt ### Using Ubuntu 14.10 and Ubuntu 14.04 Netboot Image ### For this approach download Ubuntu Netboot Images onto PXE Server using the following commands. #### On Ubuntu 14.04 #### ------------------ On 32-Bit ------------------ # cd # wget http://archive.ubuntu.com/ubuntu/dists/utopic/main/installer-i386/current/images/netboot/netboot.tar.gz ---------- ------------------ On 64-Bit ------------------ # cd # http://archive.ubuntu.com/ubuntu/dists/utopic/main/installer-amd64/current/images/netboot/netboot.tar.gz #### On Ubuntu 14.04 #### ------------------ On 32-Bit ------------------ # cd # wget http://archive.ubuntu.com/ubuntu/dists/trusty-updates/main/installer-i386/current/images/netboot/netboot.tar.gz ---------- ------------------ On 64-Bit ------------------ # cd # wget http://archive.ubuntu.com/ubuntu/dists/trusty-updates/main/installer-amd64/current/images/netboot/netboot.tar.gz For other processor architectures visit Ubuntu 14.10 and Ubuntu 14.04 Netboot Official pages at following locations and select your architecture type and download the required files. - [http://cdimage.ubuntu.com/netboot/14.10/][4] - [http://cdimage.ubuntu.com/netboot/14.04/][5] **2.** After you have downloaded the **ISO Images** or **Netboot Installer** archives copy the entire **ubuntu-installer** folder to PXE tftp server location by issuing the following commands depending on the method you have chosen. **A).** For both CD ISO Images (**32-bit** or **64-bit**) use the following command after you mounted the specific architecture CD onto PXE Server **/mnt** system path. # cp -fr /mnt/install/netboot/ubuntu-installer/ /var/lib/tftpboot/ **B).** For Netboot archives run the following commands depending on the specific Ubuntu architecture. # cd # tar xfz netboot.tar.gz # cp -rf ubuntu-installer/ /var/lib/tftpboot/ If you want to use both Ubuntu Server architectures on PXE Server, first download, mount or extract, depending on the case, the 32-bit architecture and copy **ubuntu-installer** directory to **/var/lib/tftpboot**, then unmount the CD or delete the Netboot archive and the extracted files and folders, and, repeat the same steps with 64-bit architecture, so that the final **tftp** path should have the following structure. /var/lib/tftpboot/ubuntu-installer/amd64 /var/lib/tftpboot/ubuntu-installer/i386 **3.** On the next step add the **Ubuntu 14.10** and **Ubuntu 14.04** Menu labels to **PXE Server** default configuration file by issuing the following command. **Important**: It’s not possible for me to show the instructions for both Ubuntu versions, that’s the reason for demonstration purpose, I’m adding **Ubuntu 14.04** Menu lable to PXE Server, but the same following instructions also applied to Ubuntu 14.10, only with minor changes to version numbers, just change the version numbers and path to OS architecture according to your Ubuntu distributions. Open PXE default configuration file with the help of your favourite text editor, in my case it’s nano editor. # nano /var/lib/tftpboot/pxelinux.cfg/default Next, add the following configurations to PXE Menu. #### For Ubuntu 14.04 32-bit #### label 1 menu label ^1) Install Ubuntu 14.04 x32 kernel ubuntu-installer/i386/linux append vga=788 initrd=ubuntu-installer/i386/initrd.gz -- quiet label 2 menu label ^2) Ubuntu 14.04 Rescue Mode x32 kernel ubuntu-installer/i386/linux append vga=788 initrd=ubuntu-installer/i386/initrd.gz rescue/enable=true -- quiet #### For Ubuntu 14.04 64-bit #### label 5 menu label ^5) Install Ubuntu 14.04 x64 kernel ubuntu-installer/amd64/linux append vga=788 initrd=ubuntu-installer/amd64/initrd.gz -- quiet label 5 menu label ^6) Ubuntu 14.04 Rescue Mode kernel ubuntu-installer/amd64/linux append vga=788 initrd=ubuntu-installer/amd64/initrd.gz rescue/enable=true -- quiet ![Add Ubuntu to PXE Boot](http://www.tecmint.com/wp-content/uploads/2014/11/Add-Ubuntu-to-PXE-Boot.jpg) Add Ubuntu to PXE Boot **Note**: If you want to include other Ubuntu architectures, follow the same above instructions and replace label numbers and **ubuntu-installer/$architecture_name/** directory accordingly on PXE default menu configuration file. **4.** After you have configured PXE menu configuration file, clean up the sources depending on the employed method and proceed with client PXE installations to test your configuration. ---------------------- For CD/DVD Method ---------------------- # umount /mnt ---------- ---------------------- For Netboot Method ---------------------- # cd && rm -rf ubuntu-installer/netboot.tar.gz pxelinux.* version.info Below are some screenshots for **Ubuntu 14.04** PXE Clients installations testing. ![Select Ubuntu from PXE Menu](http://www.tecmint.com/wp-content/uploads/2014/11/Select-Ubuntu-from-PXE-Menu.jpg) Select Ubuntu from PXE Menu ![Choose Ubuntu Installation Language](http://www.tecmint.com/wp-content/uploads/2014/11/Select-Ubuntu-Installation-Language.jpg) Choose Ubuntu Installation Language ![Choose Ubuntu Rescue Mode](http://www.tecmint.com/wp-content/uploads/2014/11/Select-Ubuntu-Rescue-Mode.jpg) Choose Ubuntu Rescue Mode ![Ubuntu Rescue Mode Shell](http://www.tecmint.com/wp-content/uploads/2014/11/Ubuntu-Rescue-Mode-Shell.jpg) Ubuntu Rescue Mode Shell ## Step 2: Add Debian 7 Wheezy to PXE Menu ## **5.** Adding **Debian 7** to a PXE Server, requires the same steps as for Ubuntu Server Edition as explained above, the only differences being the Netboot archive images download links and the name for the sources directory, which is now **debian-installer**. To download **Debian Wheezy** Netboot archives, go to official [Debian Netinstall Download][6] page, choose your desired system architecture from **Network Boot** menu, then hit the **netboot** link from **Directory** list and download the **netboot.tar.gz** archive from **Filename** list. While Debian offers Netboot Installation Sources for a multitude of system architectures, such as Armel, ia64, Mips, PowerPC, Sparc etc, in this guide I will only discuss **64-bit** architecture because the process of adding other architectures sources is almost the same as the current one, the only difference being the **debian-installer/$directory_architecture name**. So, to proceed further, login to your **PXE Server** with root account and grab Debian 7 64-bit Netboot archive by issuing the below command. # wget http://ftp.nl.debian.org/debian/dists/wheezy/main/installer-amd64/current/images/netboot/netboot.tar.gz ![Download Debain 7 Netboot](http://www.tecmint.com/wp-content/uploads/2014/11/Download-Debain-7-Netboot.jpg) Download Debain 7 Netboot **6.** After **wget** finishes downloading the **netboot.tar.gz** file, extract it and copy **debian-installer** directory to tftp server default path by running the following commands. # tar xfz netboot.tar.gz # cp -rf debian-installer/ /var/lib/tftpboot/ ![Extract Debain 7 Netboot](http://www.tecmint.com/wp-content/uploads/2014/11/Extract-Debain-7-Netboot.jpg) Extract Debain 7 Netboot ![Copy Debain 7 Netboot to FTP](http://www.tecmint.com/wp-content/uploads/2014/11/Copy-Debain-7-Netboot-to-FTP.jpg) Copy Debain 7 Netboot to FTP **7.** To add **Debian Wheezy** labels to **PXE Menu**, open PXE Server default configuration file with your favorite text editor and add the below labels. # nano /var/lib/tftpboot/pxelinux.cfg/default PXE Label Menu for Debian Wheezy 64-bit. label 7 menu label ^7) Install Debian 7 x64 kernel debian-installer/amd64/linux append vga=788 initrd=debian-installer/amd64/initrd.gz -- quiet label 8 menu label ^8) Install Debian 7 x64 Automated kernel debian-installer/amd64/linux append auto=true priority=critical vga=788 initrd=debian-installer/amd64/initrd.gz -- quiet ![Add Debian to PXE Boot](http://www.tecmint.com/wp-content/uploads/2014/11/Add-Debian-to-PXE-Boot.jpg) Add Debian to PXE Boot **Note**: If you want to add other Debian architectures repeat the above steps and replace label numbers and **debian-installer/$architecture_name/** directory accordingly on PXE default menu configuration file. **8.** Before testing the configuration on clients side, clean up Debian sources by issuing the following command. # cd && rm -rf debian-installer/ netboot.tar.gz pxelinux.* version.info **9.** Then network boot a client machine, choose Install Debian from PXE menu and proceed further with the installation as normally. ![Select Install Debian from PXE](http://www.tecmint.com/wp-content/uploads/2014/11/Select-Install-Debian-from-PXE.jpg) Select Install Debian from PXE ![Select Debian Install Language](http://www.tecmint.com/wp-content/uploads/2014/11/Select-Debian-Install-Language.jpg) Select Debian Install Language That’s all the steps required to add and install **Ubuntu** or **Debian** from a RHEL/CentOS 7 PXE Server onto your network client machines. On my next article I will discuss a more complicated method on how you can add and perform network installation for **Windows 7** on client computers using RHEL/CentOS 7 PXE Network Boot Server. -------------------------------------------------------------------------------- via: http://www.tecmint.com/add-ubuntu-to-pxe-network-boot/ 作者：[Matei Cezar][a] 译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) 本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 [a]:http://www.tecmint.com/author/cezarmatei/ [1]:http://www.tecmint.com/install-pxe-network-boot-server-in-centos-7/ [2]:http://releases.ubuntu.com/14.10/ [3]:http://releases.ubuntu.com/14.04/ [4]:http://cdimage.ubuntu.com/netboot/14.10/ [5]:http://cdimage.ubuntu.com/netboot/14.04/ [6]:https://www.debian.org/distrib/netinst
