Free Alternatives to Red Hat Enterprise Linux 3.0?
looper_man writes "I'm a hardware design engineer, and our tools have been migrating to Linux over the last years. I've been running Red Hat Linux 9.0 on our compute servers for a while now without a problem. The latest release of one of our CAD tools requires Red Hat Enterprise Linux 3.0, and will *not* run with RH9.0. I'm not very happy with the (yearly!) licensing fees that Red Hat wants for RHEL3.0, so I'm looking for alternatives. I plan on running one real RHEL3.0 server (for any OS/tool issues if I need to verify that the problem is real), and the rest of the machines running a RHEL3.0 clone. I've seen CentOS, TaoLinux, WhiteBox, and a few others. I don't have the time to spare to test these out, so I was looking for recommendations from the Slashdot masses. I need something that's stable, easy to install/maintain, and closely tracks RHEL3.0. Any words of wisdom?"
CentOS is simply a recompiled and rebranded RHEL with swift security updates. If you want something as similar as the real thing, CentOS is certainly the way to go.
This is your sig. There are thousands more, but this one is yours.
To all you reccomending Fedora: Fedora is NOT binary compatable with RHEL. Binaries made for RHEL may not run under Fedora. I'd reccomend Scientific Linux, maintained by Fermi Lab. They keep it as up-to-date as RHEL is, and they include apt and yum for updating. Install mirrors the RHEL install, and is binary-compatable with RHEL.
CentOS is pretty much an exact copy of RHEL, except for trademark names and artwork, so it should work flawlessly...except for one thing. If the installer is explicitly checking versions, backup and then replace the redhat-release file found in
CentOS, WBEL, and Fermi LTS Linux. All of them worked well enough for me - the differences were that it seemed Fermi LTS was fairly heavily customized for the lab's needs, so it wasn't that great for new package installation. WBEL was very vanilla, but sometimes support was slow. CentOS seemed to have the best support behind it, so I use it now - recently I upgraded to CentOS 4.
Another option to look at for low cost is SuSE. SuSE Pro is inexpensive, and the odds are that your CAD vendor supports it. Plus you can actually get support from SuSE.
