How to install CentOS 6 using remote install over the internet – aka Net Install
If you want to install CentOS 6 using remote install there are few easy steps. First you need the CentOS 6 net install CentOS-6.2-x86_64-netinstall.iso which is about 227 mb. You can get it here: http://centos.netnitco.net/6.2/isos/x86_64/CentOS-6.2-x86_64-netinstall.iso Next you burn the cd or mount the iso in a virtual machine and boot up the system. When it asks where your install media can be located you select “URL”. Next, use either of the following paths:
32 bit: http://mirror.centos.org/centos/6/os/i386/ 64 bit: http://mirror.centos.org/centos/6/os/x86_64/ If these dont work you can try these: http://mirror.centos.org/centos/6.0/os/x86_64/images/ http://mirror.centos.org/centos/6.0/os/i386/images/
Finally hit next and you should be on your way. The install should continue as normal and everything the system needs to complete the install will be downloaded and installed.
This was originally designed so you could host the install files on your local network or ftp server but works just as well over the internet. This is especially useful if you want to do a minimal install so you don’t have to download the entire 4+GB ISO file.
