First, this lesson mainly contains the following content
1.1 Beginning of study
1.2 conventions
1.3 Understanding Linux
1.4 Creating a virtual machine
1.5 Installing CENTOS7
second, the beginning of learning
1 What is the purpose of studying this course?
A: First of all, I like operation and maintenance of this job, the second is to make money. So to learn the course, for the future to lay a good foundation for work!
2 What is the post you want to do after you finish your study?
A: The initial job is to do Linux operations engineer, more in the work of continuous learning, always through experience, slowly to the architect development.
3 in which city will you develop after you finish your studies?
A: The temporary idea is to develop in the local provincial capital city, and then consider going to the big cities after the technology and capacity are improved.
2.1. Set goals for yourself
1 when did you finish your study?
Answer: Of course, the shorter the better, but must learn solid.
2 When is the job?
A: The plan is next year. This year and the company signed a contract, want to jump a little trouble.
3 First job pay?
A: Must be the local capital city, consumption is not so high, expected not less than 6500
4 What is the salary after one year? What about two years later?
A: Not 8000 a year later, I'm sure I can't stay. Two years later, if the ability to improve, can be qualified for more jobs, less than 10K certainly do not do.
2.2. Learning Methods
1 Preview and review the same important this is certain, the key is to insist on doing it.
2 on the day of completion of this must be done, even if it is late to sleep, but also to complete.
3 notes in the ordinary work, and of course know the importance of notes. A good memory is inferior to a bad pen.
4 Use good resources video + blog + Teacher's guidance + classmates help each other
2.3. Value of the course
1 in the course validity period to repeat the learning video. Practice makes perfect
2 study, job search, after work regardless of which stage, can use the existing resources, continue to learn and improve themselves.
3 Circles I think this should be the most important value of the course.

iv. knowledge of Linux
1 Linux is an operating system
- Before the Linux system the popular operating system is UNIX (Mac OS)
- A system developed by a university teacher for teaching Minix
- 1991, our protagonist Linus Torvalds reference Minix developed the Linux
- The GNU (GNU Not Unix), also known as the slave program, was publicly launched by Richard Stallman on September 27, 1983. Its goal is to create a complete set of free operating systems
- The GPL simply says that materials posted to the Internet under the GPL can be used or changed, but the material that you change and then re-release must also comply with the GPL, the main requirement being open source, and not deleting the original author's claim information.
2 run ppt, browse websites, play games, etc.
3 The Android phone that everyone uses now is a Linux kernel operating system
4 Website Games QQ, these platforms or the software uses the server system, all is the Linux system. The future of smart devices, it is possible to use the Linux kernel developed by the system.
5 Linux distributions
- Debian 1993 →ubuntu 2004
- Slackware 1993 →suse 1994
- Redhat 1994 →centos 2003
- Redhat→redflag 1999
- Redhat Fedora RHEL 2002

V. Create a virtual machine
1 virtualization software used: VMware Workstation 10 (see above)
The specific installation process will not be mapped, and the common Software installation method, the next step is possible. If you need to activate the code, you can search Baidu.
2 Installing the operating system Centos 7.4
The installation process is skipped, the installation times are too many, this does not map.
Note the following points:
- The maximum disk size, which can be assigned to 20G, is not used all the time, but increases as the storage content increases. Choose to store the virtual disk as a single file
- Network adapter, there are three modes: Bridge mode, NAT mode, host mode only. NAT is recommended here, no matter where your notebook is used, the network can be connected properly
Vi. installation of centos7.4
Note the following points:
- Choose to minimize the installation, we do the experiment, do not use the graphical interface.
- Install location, automatically identify the hard disk, select the partition I want to configure.
- Select Standard Partition, click the + sign in the lower left corner, add mount point with/boot 200, default unit m
- Continue to add mount point/swap size by memory twice times set, maximum no more than 8G, Unit is also m
- Finally, all the remaining load capacity is divided into/root partition, if later work, according to the company's specific requirements to allocate disk size.
- Point to start the installation, the best step is to set the root password. Be as complex as possible. Password more, you can use the software KeePass described above to save.
Learn Linux with Amin, create virtual machines, install CENTOS7 operating systems
