從遠端重安裝CentOS,How to re-install Centos yourself remotely
以下範例是從Centos 5 64-bit變更為Centos 5 32-bit Assuming you currently have a Centos 5 64-bit that was installed by us (if you have or want 32-bit, set/use 32-bit accordingly). Below will reinstall to Centos 5.6 64-bit, change it accordingly if you want other versions of centos. 1. SSH to your server and login as root 2. Type below: mkdir /centos_install
cd /centos_install wget http://vault.centos.org/5.6/os/x86_64/images/pxeboot/initrd.img wget http://vault.centos.org/5.6/os/x86_64/images/pxeboot/vmlinuz cp vmlinuz /boot/vmlinuz.cent.pxe cp initrd.img /boot/initrd.img.cent.pxe 3. Add to/Edit the grub menu.lst entry to load the pxe kernel (note: if you were already using grub you do not need to type again the first 2 lines) nano -w /etc/grub.conf in that file paste this in BETWEEN "hiddenmenu" and "title CentOS..." (IMPORTANT): replace
Hint: you can see the gateway ip by issuing route -n | grep UG once you have done this you need to count the number of times “title” appears in the file, press ctrl +x, and save the file 4. Reboot the server by typing reboot 5. Assuming above is done correctly, you can then use vncviewer (download from realvnc.com) and connect to YOURIPHERE:1 And password is whatever you set above. |
