What is linux server?
linux server(server).
Linux has a variety of servers, such as Red hat and Ubuntu.
Enterprises generally use Red Hat. The difference mainly depends on the size of the installation disk. A Fedora (RedHat) disk is a DVD, while an Ubuntu disk is just a CD. In terms of software packages, Fedora has many more packages than Ubuntu, although Ubuntu can be installed separately. But there are definitely not as many on the CD as there are on RedHat.
In addition, I have also personally tried the server version of Ubuntu. I installed it on a laptop with a certain CPU. The server version of Ubuntu could not support this CPU, which made me very depressed. However, Fedora definitely does not have this phenomenon. This shows that RedHat has excellent compatibility. Only with good compatibility can the system be stable. It is suitable to be a server. Just imagine, if the system has poor compatibility with the hardware, the system itself will collapse without the need for hackers and viruses.
Linux Introduction:
Linux, the full name is GNU/Linux, is a UNIX-like operating system that is free to use and freely disseminated. Its kernel was developed by Linus Benedict Thomas. First released by Linus Benedict Torvalds on October 5, 1991, it is mainly inspired by the ideas of Minix and Unix. It is a multi-user, multi-task, multi-threading and multi-CPU operating system based on POSIX. It supports 32-bit and 64-bit hardware and can run major Unix software tools, applications and network protocols.
Linux inherits the network-centric design philosophy of Unix and is a multi-user network operating system with stable performance. There are hundreds of different Linux distributions, such as Debian and Archlinux based on community development, and Red Hat Enterprise Linux, SUSE, Oracle Linux, etc. based on commercial development.
With the development of the Internet, Linux has received support from software enthusiasts, organizations, and companies around the world. In addition to maintaining a strong momentum of development in servers, it has also made great progress in personal computers and embedded systems. Users can not only intuitively obtain the implementation mechanism of the operating system, but also modify and improve Linux according to their own needs to maximize it to meet the needs of users.
Linux not only has stable system performance, but also is an open source software. Its core firewall components have high performance and simple configuration, ensuring system security. In many corporate networks, in order to pursue speed and security, Linux is not only used by network operation and maintenance personnel as a server, but even as a network firewall. This is a highlight of Linux.
Linux has the characteristics of open source, no copyright, and a large number of users in the technical community. Open source allows users to tailor it freely, with high flexibility, powerful functions, and low cost. In particular, the network protocol stack is embedded in the system and can function as a router after proper configuration. These characteristics make Linux an ideal development platform for developing routing and switching equipment.
