Last night I downloaded the latest CentOS 6 DVD ISO via bittorrent, but for some reason it was corrupted, so instead of redownloading the whole 4.3Gb image again, I thought I’d try out the net install as it’s only about 170Mb.
However when you get to the screen it asks you for the URL to download the install image. Hmm. Originally, the Net Install method was designed so you could do an install from images hosted on your network or on some local FTP server. I have neither. Luckily the CentOS mirror provides the necessary images. The following URL may save you some head scratching:
32 bit: http://mirror.centos.org/centos/6/os/i386/ 64 bit: http://mirror.centos.org/centos/6/os/x86_64/
Thats it. The installer will fetch what it needs from that URL and you’ll be on your way.
