Notes on installing a PXE bootserver that boots diskless terminalservers by use of nfsroot. Three machines have been set up for this:<\/p>\n
| Name<\/th>\n | IP<\/th>\n |
|---|---|
| bootserver<\/td>\n | 192.168.65.1<\/td>\n |
| ts1<\/td>\n | 192.168.65.11<\/td>\n |
| ts2<\/td>\n | 192.168.65.12<\/td>\n<\/table>\nbootserver<\/h3>\nA typical install of FreeBSD have been used. Only including base, generic kernel and lib32. After it’s installed, By creating the dump on a different filesystem, it won’t be included (in the dump). If another filesystem cannot be mounted by nfs or usb or whatnot, the nodump flag can be set on the resulting dump by use of for instance This entire process can be copied to create additional terminalservers.<\/p>\n \/var needs to be mounted on a virtual ramdisk device so we don’t need the contents of \/var on the terminalserver. \/var itself still must exist in order to be able to mount a filesystem on top of it.<\/p>\n Back to the bootserver and configure necessary daemons.<\/p>\n I have also set up a NIC for management on another network so this is in order for inetd to only listen on the pxeboot lan.<\/p>\n Uncomment the tftp line for ipv4<\/p>\n Then create a link to the bootloader<\/p>\n This is a port that needs to be installed. I simply fetched it from my package building server.<\/p>\n In distributed computing it’s important that the time is the same on all involved servers. Thus bootserver will serve time to the terminalservers. If it’s also connected to the Internet, it can ask other ntp servers for time. If not, it doesn’t matter if the time is correct. What matters is that it is the same on the terminalservers.<\/p>\n Now the terminalservers are ready for booting but a couple of preparations need to be done on them before that. These preparations need to be done on all terminalservers that have been created.<\/p>\n The \/var filesystem needs to be put on a virtual ramdrive device by the following. If you find your terminalservers \/var filesystem growing you need to increase its size. I’ve chosen 64Mb which is plenty thus far.<\/p>\n (run this to create the initial snapshot) <\/code><\/p>\n In order to access the terminal servers, ssh keys should be set up. It's also advisable to put all hostnames in \/etc\/hosts on bootserver and the terminalservers.<\/p>\n On bootserver<\/p>\n \/etc\/hosts looks like this that need to be synced to all servers:<\/p>\n Now you have a terminalserver farm that can easily be expanded with endless possobilities of distributed computing! \ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":" Notes on installing a PXE bootserver that boots diskless terminalservers by use of nfsroot.
