Red Hat Enterprise Linux (RHEL) 4.0 xSeries: x86-32
I don’t know what this xSeries is, but the latter x86-32 indicates that it is a 32-bit architecture of ordinary x86. Now Basically, it can be installed on all machines, but RHEL 4.0 is very old, and there may be problems with not having drivers and not being able to use some new hardware. RH usually has an update every three months to half a year, and now the latest version of the 4 series is 4.8 (should be Called 4 update 8), this should be the last version of the RHEL 4 series.
If there are no special requirements, please use RHEL 5 series, the latest is 5.4 (the same official version is 5 update 4).
Red Hat Linux release 9 (shrike) is not an enterprise version. It is the last version of the personal version released by RedHat 7 years ago. After that, RedHat gave up the development of personal systems and switched to supporting the Fedora series. In other words, Fedora Core 1 plays a similar role to Red Hat Linux 10. But it is not released by RedHat, it is released by the Fedora project. The latest version is Fedora 12 (the name was slightly changed halfway and Core was deleted, because there used to be Fedora Extras, which was canceled halfway, so Core is no longer needed. .
If you have money, you can consider choosing RHEL, because all its after-sales services are paid items, including online updates.
If you don’t have money and still want to use RHEL, you can consider it. Switch to CentOS, which is a recompilation of RHEL. For information about it, please google.
If you are not just for the server, you can consider using Fedora.
There are also other options. SUSE Enterprise Linux is also released for enterprises. Compared with RHEL, this one is more suitable for enterprises that have transferred from Windows (Novell has Microsoft's authorization and can implement some Microsoft patented technologies, but most of them are the same...) . Only if you have money. If you don’t have money, openSUSE is in a similar position to Fedora.
