Bell Labs Unix Ken Thompson & Dennis Ritchie

Two people cooperate with the assembly language to complete the writing UNIX. 1972 The birth of the C language. In 1973, the two were re-written in C language.

UNIX to enable the migration of UNIX system data.

"Linux development Prospects"

1.Linux Open Source System--the preferred solution for Internet companies

2. High security and stability

3. High-paying professional skills

"Linux Jobs"

"Advantages of virtual machines"

1 , can simulate the real operating system, do a variety of operating system experiments (such as: Build a domain server, build a Web server, build FTP server, build a DHCP server, build a DNS server, etc.);

2 , the snapshot capabilities of virtual machines are comparable to the Ghost tool backup feature, and you can quickly create restore points or recover restore points quickly;

3 , can bridge to the real computer on the Internet, better guarantee the security;

4 , in the case of only 1 computers, the need for several other computers together to build a complex application environment, virtual machine can do;

5 , you can test the more suspicious tools in the virtual machine;

6 , the real tool can be used in the virtual machine normal use "premise to simulate the corresponding operating system";

7 , you can quickly clone the operating system copy.

"Installation of VMs"

The specific installation steps are omitted, similar to the normal software installation process.

There are only a few suggestions:

1. The Software installation directory as far as possible not selected in the C disk;

2. The virtual machine's hard disk mount is selected "multi-file mode";

3. Put a folder on a virtual machine.

"Installation of RHEL7.2"
