Linux version CentOS, Ubuntu and Debian similarities and differences

Linux has a very large number of distributions, broken down in nature, and broadly divided into commercial versions maintained by commercial companies and free releases maintained by the open source community.

The commercial version is represented by Redhat, and the open source community version is represented by Debian.

#Ubuntu系统

Ubuntu has a bright user interface , a complete package management system, strong software source support, a rich technical community, and Ubuntu support for computer hardware better than CentOS and Debian, compatibility, Ubuntu application is very much,

But for the server system, personal feeling does not need a lot of various applications, need is stable, easy to operate, maintain a simple system.

If you need to use the graphical interface on the server side, Ubuntu is a good choice, you need to be aware that the graphical interface occupies a very large amount of memory, and the larger the memory of the VPS price is also higher.

#CentOS系统

You will find that a lot of commercial companies deployed in the production environment are using the CentOS system, and CentOS is a community re-release version compiled from Rhel (Red Hat) source code.

CentOS removes many applications unrelated to server functionality, is simple but very stable , and command-line operations facilitate the management of systems and applications, as well as help documentation and community support.

--compared to Debian, CentOS is slightly larger.

#Debian系统

Debian is also ideal for server operating systems,

The entire System Foundation core is very small, not only stable , but also occupy hard disk space and memory is small , 128M VPS can run Debian smoothly, and CentOS will be a little laborious,

However, Debian's help documents and technical data are relatively small . For small memory, Debian is preferred.

--relative to Ubuntu, it's not too much of a fancy, relatively stable;
-relatively few help documents and technical data compared to CentOS;

In the system's choice, belongs to the novice, the preferred CentOS, is not CentOS is better than Debian and Ubuntu, but CentOS is the first choice for beginners to install VPS, it is stable, occupies less resources, the network can easily search the installation configuration of the document, its own Help document is very powerful ；

However, if the VPS configuration is too low, Debian is recommended, otherwise it is recommended to use CentOS for more online help and support, making it easier for you to get started.

While Ubuntu, the system although free, but it is suitable for the rich to play, it occupies more resources than the previous two systems higher, and VPS basically is to sell memory, the higher the memory, the higher the price.
