Small Ant learning Linux (1)--linux simple introduction to VMware virtual machines

Today began to learn Linux, a long time ago has studied Linux, at that time learning is quite serious, but not long, the memory is not to force, decisive or to forget about the same time, the notes did not know where a small corner lost, no matter how it is, Start this wonderful Linux tour today and come on!

Linux History

Tan Ningbong-Minix

Linus--> with Minix as a template, developed Linux (1991)

There are two versions of Linux:     

Kernel version and the Release version

Kernel version of Linux kernel www.kernel.org the website can be downloaded to.

Release version of the manufacturers according to their own understanding, in the kernel version of the expansion of development, the formation of the current market many Linux products, such as: Redhead, CentOS, Ubuntu and so on.

Application areas of Linux

1. Linux-based Enterprise servers. 2. Embedded applications

Linux and Windows are different:

1. Linux is strictly case sensitive

2. All contents of Linux are saved as files, including hardware (all contents are files)

3. Linux does not differentiate file types by extension, depending on permissions.

But there are some conventional "extensions" that need to be remembered for the convenience of human work, as follows:

Compressed package:. gz. gz2. tar.bz2. tgz

Binary package:. rpm

Web page files:. html. php

Script file:. sh

Configuration file:. conf

Why do Linux servers use the character interface?

1. Consume less system resources 2. Reduces the likelihood of an error, being attacked

VMware virtual Machines

VMware virtual Machine If the removal is not clean, it is possible to cause the problem of reinstallation failure, you can use this tool to solve the problem: Vmware_install_cleaner

VMware Virtual Machine Network connectivity explained:

1. Bridging can communicate with itself, or it can communicate with other devices in the network segment, but it requires an IP address.

2. NAT: Use Vmnet8 to communicate with your real machine. Virtual machines can surf the internet.

3. Host-only: Use Vmnet1 to communicate with your real machine. Virtual machines cannot be connected to the Internet.

If 2 or 3 is selected, the virtual machine can only communicate with its own real machine and cannot communicate with his device. Recommended Use Bridge!!

Benefits of using VMware virtual machines:

1. Snapshots return to a previous point at any time

2. Cloning without reinstalling the configuration, you can easily get an identical system, very convenient.
