I want to re-install centos 6.8 with custom partation layout on my dedicated server that comes with cent os 6.7.
I tried following settings on a vps first and i am able to connect via vnc for remote installation.
I tried same settings on the dedicated server but i am unable to connect via vnc.
downloaded following files on /
wget ht*tp://mirror.centos.org/centos/6/os/x86_64/isolinux/vmlinuz -O vmlinuz-7
wget ht*tp://mirror.centos.org/centos/6/os/x86_64/isolinux/initrd.img -O initrd-7.img
edited the grub , added following lines nano /boot/grub/grub.conf
title CentOS 6 VNC Installation
root (hd0,0)
kernel /vmlinuz-7 vnc vncpassword=12345678 headless ip=******.130 gateway=*****.129 netmask=255.255.255.248 dns=8.8.8.8 ksdevice=eth1 repo=ht*tp://mirror.centos.org/centos/6.8/os/x86_64 lang=en_US keymap=us
initrd /initrd-7.img
verified that eth1 is the working network. then
echo 'savedefault --default=1 --once' | grub --batch
and rebooted the system but never able to connect back.
How can check if there is some error ? Can I log it? , on VPS it was easy as I had vnc access. but with a dedicated server in a datacenter there must be some option to log the errors.
