Know Linux, create virtual machines, install CentOS 7

1. Understanding Linux

#linux是一个操作系统平台

#在没有linux前是Unix的天下, Unix is not free, need authorization, the average person can not afford it.

#1983年, the computer community, Richard Stallman, has launched a plan to build a completely free and free operating system for everyone to learn, and this is the famous GNU program. (The so-called freedom is the software that joins the GNU program must be free to use, freely change, free to publish.) In order to restrict everyone's freedom to use this set of rules is the famous GPL agreement)

#GNU计划发起后, there have been great software such as VI, Emacs, GCC and so on, until 1991, Finnish university student Linus-Benner-Torvalds (Linus Benedict Torvalds) developed a UNIX-like operating system based on interest, After the release of a lot of people after the stick, the system is linux,1994 Linux to join the GNU program and released under the GPL, since the Gnu\linux really realized the idea of building a completely free operating system.

#比较出名的版本有Debian (1993) and Slackware (1993), Red Hat (1994) was born, Ubuntu (2004) out of the relatively late Debian based on the development of the Debian Branch, Slackware also has a more famous branch of SuSE (1994)

#Android系统也是一种Linux的发行版本, Red Hat is a very famous Linux branch, a Linux distribution in China Red Flag (1999) is based on Red hatn distribution, but this version of the people are not much, not popular. 2002 Red Hat launched a new release for Enterprise Red Hat Enterprise (RHEL), and the previous Red Hat was no longer released and was continued by another release, which is known as Fedora (beta, stable), All of the new technologies released in Rhel have to be tested on fedora before being ported to Rhel.

#Centos诞生于2003年, since Red Hat is based on GNU, it has to follow the GPL, and after Rhel releases all of its source code, CentOS was compiled with Rhel source, and in February 2014, CentOS was in Red Hat's pocket, The reason for this is that the CentOS distribution has been widely popular, with Red Hat officially attached to it.

2. Create a virtual machine

Note: Download VM virtual machine (please download VMware workstation The latest version of virtual machine installed by yourself.)

Open VM Virtual machine, click Create New virtual machine

The default selection is typical and the next option is to install the operating system later.

Next, the system chooses Linux, version select CentOS 64-bit

Next, the virtual machine name can be renamed itself, if not required to remain the default, the location of the virtual machine can be changed.

Next, disk space can be based on their own needs to freely allocate space, virtual disk storage files are single or multiple to see their own needs to choose, my side choose the default.

Next, the custom hardware memory and CPU can choose the operation according to their own needs, general test using 1G of memory 1 CPU is enough to use, network card mode configuration according to their own network environment choice, if you do the experiment using the recommended choice NAT mode.

3, Installation Centos7

After the creation of the virtual machine, we put the ISO file on the CD (Centos7.0 system Baidu own download), select boot Start, the completion of the confirmation, click to open the virtual machine.

For example, need to configure where there are installation source and software selection of the two can be based on their own needs to choose, do not need to keep the default, where the need to change the installation location, mouse click in, the hard disk has been selected by default, in the storage options select "I want to configure the partition", others remain the default, click Finish.
