Main difference between Ubuntu and Redhat?

Question

Except package management and environments , I would like to know what's the main points between them .

which are providing best support to their builds ?

Answer 1

There are a few different ways to interpret "Redhat" here:

1. Red-hat Enterprise Linux - A specific, commercial distribution by Red Hat.

2. Distributions which are based on or inherit from Red Hat, which would also include CentOS and Fedora, and their derivatives.

3. RPM-based distributions in general - that is, distributions that use the Redhat Package Management system. This would expand your scope to include distributions like SUSE, Mandriva, PCLinuxOS, and their derivatives.

The answer may be different depending on which one you mean.

1. If you are referring to Red Hat Enterprise Linux specifically, then by far the biggest difference is the license terms - Red Hat Enterprise Linux is commercial.

   You can, however, get the same distribution, but without the commercial contract, for free in the form of the CentOS distribution.

2. If you are including also Fedora and CentOS, then it's actually very hard to compare all those as if they are one thing. They are all very different in themselves. The one thing they have in common, which sets them aside, is their package manager, which I talk about below.

3. If you are referring to any RPM-based distribution, then the biggest difference would obviously be the package manager. Ubuntu is based on Debian's package manage based on APT and DPKG. Red Hat, CentOS and Fedora are based on the old Red Hat Linux package management system, RPM. Both package managers are now quite mature and have roughly equivalent features. You could debate invidual design decisions though but it's hard to say that one overall is better than the other.

Answer 2

Main Difference is Ubuntu is based on Debian system. It uses .deb packages. While redhat uses it own package system .rpm (red hat package manager ).

Redhat is free but it is charged for support (updates), when Ubuntu is totally free with support for desktop users only professional support is chargeable.

Answer 3

There are several points between these two to differentiate them. In easy words differences are:

1. Ubuntu Desktop enterprise edition (Business Desktop Remix) is free to use but Redhat is not.
2. Ubuntu focuses on Desktop users, in other hand Redhat main focus is Server platform.
3. Red Hat is made by Red Hat Inc. is founded by Young and Ewing while Ubuntu is headed by Shuttleworth, owner of Canonical Ltd.
4. Ubuntu is based on Debian (a very famous and stable Linux OS), but Redhat has nothing like this.
5. Ubuntu executable file extension is .deb (which uses other Debian based OS i.e. Linux Mint), whether Redhat executable file extension is .rpm (which means Redhat Package Manager).

Answer 4

Red Hat Enterprise Linux is not free, and its also used for business.Red Hat Linux, assembled by the company Red Hat, was a popular Linux based operating system. Red Hat Linux 1.0 was released on November 3, 1994. It was originally called “Red Hat Commercial Linux” It is the first Linux distribution to use the packaging system, the RPM Package Manager as its packaging format, and over time has served as the starting point for several other distributions, such as Mandriva Linux and Yellow Dog Linux.

Red Hat’s Features:

• Red Hat Linux introduced a graphical installer called Anaconda, intended to be easy to use for novices, and which has since been
  adopted by some other Linux distributions.
• It also introduced a built-in tool called Lokkit for configuring the firewall capabilities.
• It uses .rpm package called Red Hat Package Manager.

RPM Package Manager (RPM) is a powerful command line driven package management system capable of installing, uninstalling, verifying, querying, and updating software packages.

Each software package consists of an archive of files along with information about the package like its version, a description, etc.

Ubuntu Ubuntu is an operating system, like windows. Ubuntu is a Linux distribution that starts with the breadth of Debian and adds regular releases (every six months), a clear focus on the user and usability (it should “Just Work”, TM) and a commitment to security updates with 18 months of support for every release. Ubuntu ships with the latest Gnome release as well as a selection of server and desktop software that makes for a comfortable desktop experience off a single installation CD.

• Ubuntu uses the.deb apt package:- Ubuntu uses .deb package for package installation as like .rpm of Red Hat.
• Ubuntu also uses apt-get package installer to install packages by using command mode. To install package Graphically, synaptic package
  manager.
• Ubuntu is Debian based.¹
