know Linux:

Linux is an open source free operating system because it is stable and secure and is widely used on servers. before Linux was born, there was an operating system called Unix, andUnix was The earliest by Kenthompson, Dennis Ritchie and Douglas McIlroy in 1969 in atof theBell LabsDevelopmentof the.

at that time, because Unix was registered trademark began to charge, the cost is equivalent to a computer, so individuals, small companies, students can not use the operating system, then there is a group of IT industry geek, engineers, Enthusiasts want to have a free, open source, free environment for software and systems to launch the GNU Program,theGNU program is by Richard Stallmanpublicly launched on September 27, 1983.Free SoftwareCollective Collaboration program. Its goal is to create a set of completelyFreethe operating systemGNU. then a few years laterProfessor Andrew S. Tanenbaum of the Computer Science department at Vrije University in Amsterdam, Netherlands , decided to use the source code without using any of the AT/T sources in order to teach the practical details of the operation of the student operating system in class. Develop a UNIX-compatible operating system on its own to avoid copyright disputes. He referred to it as a minix, with the meaning of small UNIX (Mini-unix). Minix was originally released in 1987, opening allSource Code Teaching and research to the university. 2000 re-changed to BSD licensing to become free and open source software.

At the time Minix was used extensively in teaching, a university student in Finland Linus Torvalds, according to Minix developed a Linux Operating system kernel, so Linux is developed according to Minix , and Minix indirectly stems from Unix. Linus Torvalds The kernel of the Linux operating system to Comp.os.minix,available to others to download. in 1993, about 100 programmers took part in the coding/modification of the Linux kernel, where the core group consisted of 5 people, at which time the code for Linux 0.99 was about 100,000 lines and the user was around 100,000.

Linux development So far, there are many distributions, the most common distributions are: RedHat, CentOS, Ubuntu, Debian and so on. Redhat is widely used in domestic enterprises, CentOS is derived from Redhat and redhat with high similarity, so most individuals use CentOS to learn.

installation of CentOS:

installation CentOS needs to download a VMware Workstation Pro virtual machine software first, and download a centos system ISO The disc image can be downloaded on the official website.

The CentOS system ISO CD image is on the website:

Http://101.110.118.69/isoredirect.centos.org/centos/7/isos/x86_64/CentOS-7-x86_64-Everything-1611.iso

Create a new virtual machine after you are ready to complete:

First Partition boot, boot is the relevant directory, in Linux There is no drive letter, only the file directory, the file directory of these systems is equivalent to Windows the drive letter:

then partition swap,This is the swap partition, similar to the Windows virtual disk, the purpose is when your memory is not enough to take a part of the physical disk, the memory of the unused data temporarily on the disk, sub-partition , generally twice times the deposit, but if the memory is greater than 4G , it is best to divide only 8G.

then the rest of the capacity is divided into the root directory, this step does not need to fill the capacity the following:

then the rest of the capacity is divided into the root directory, this step does not need to fill the capacity the following:

after the installation is complete, reboot and enter the root account and password to log in:
