PXE The Preboot eXecution Environment (PXE, alsoknown as Pre-Execution Environment; sometimes pronounced "pixie") is an environment to boot computers using a network interface independently of data storage devices (like hard disks) or installed operating systems.
NFS Network File System (NFS) is a distributed file system protocol originally developed by SunMicrosystems in 1984, allowing a user on a client computer to access files over a network in amanner similar to how local storage is accessed. .
What you will need:● A system with a network interface (2)?● Running PC-BSD 9.1 / TrueOS 9.1● A few GB of disk space
Getting Started● First, checkout a FreeBSD ports tree On TrueOS# portsnap fetch extract update
On PC-BSDControl panel → System Manager → Tasks→ Fetch Ports
Example install archive:installMedium=locallocalPath=/installarchivepackageType=tarinstallFile=fbsd-release.txzChanged to custom archive:installMedium=locallocalPath=/installarchivepackageType=tarinstallFile=fbsd-8.4-amd64.txz
installPackages=apache22 mysql55-serverCan use short package names, or fullversions.
Scalability● Default DHCP server is configured for 99 clients● To adjust edit the file: ● /usr/local/etc/dhcpd.conf ● range 192.168.2.100 192.168.2.199;
Putting the Automated in “Fully Automated” File: /home/thinclient/installscripts/unattended.cfg● If config exists, the client will boot and begin installation after 30 seconds.● System will shutdown when finished● USE WITH CAUTION!!
Tips and Tricks● The PC-BSD GUI installer is your friend● Every install is a scripted install● After installation a copy of the pc- sysinstall.cfg file is saved to: ● /root/pc-sysinstallcfg
Tips and Tricks● To greatly speed up installations, use ZFS mirrored drives, SSD, or even TMPFS
Whats next?● Improvements to pc-sysinstall ● Allows dist-file installation ● PKGNG support● Faster setup of initial thin-client environment
