[CentOS] Install CentOS 7 over serial port on router board ?
Hi, I have to install CentOS 7 for a client, to act as cache & filtering proxy using Squid. I'd like to use this piece of specialized hardware : http://store.calexium.com/fr/systeme-pre-assemble/869-systeme-pre-assemble-rackmatrix-apu-amd-gx-412tc-quatre-coeurs-1-ghz.html There is no VGA or HDMI video output, just a serial port to connect to, and then three NICs and two USB ports. I've never installed CentOS over a serial console, so I don't even know if it's possible in the first place. Has anyone ever done something like that ? Any suggestions ?

Failing that have you considered installing Centos to the mSATA disk on a different system and then just transplanting the built system into this appliance?> Niki

Set anaconda to provide vnc, then connect to the vncserver and install using the normal graphical installer just like you would on a default install. jh

Change console settings to point to the serial port as per Giles. Use a USB-to-serial converter to connect to a laptop running a terminal program, or serial cable with a dekstop that still has a serial port. May need a null-modem cable, I don't remember.

Use a USB-to-serial converter to connect to a laptop running a terminal program, or serial cable with a dekstop that still has a serial port. May need a null-modem cable, I don't remember.We use a DIGITUS USB2Serial Converter (Prolific based USBID: VID:067B PID:2303) and then screen /dev/DEVICE 115200 -- LF
