May 23, 2021 That's what Linux should learn
The so-called "work to do good, must first al-Al, " in this chapter of the learning process, the reader needs to build for future exercises using the Red Hat RHEL 7 system environment. Y ou don't need to buy a new computer specifically to practice your experiments, and here's how to simulate a simulation system with virtual machine software. A virtual machine is software that enables users to simulate multiple operating systems on a single real machine. G enerally speaking, the current mainstream hardware configuration is sufficient to install virtual machine tasks, and according to Mr. Liu Wei nearly 10 years of operation and maintenance technology learning and many years of online training experience, it is recommended that you regardless of whether economic conditions allow, should not be installed during the study period Linux system on top of the real machine, because in the learning process is inevitable to "toss" your Linux operating system. The system installed through the virtual machine software can not only simulate the hardware resources, the experimental environment and real file separation to ensure data security, even cooler is when the operation error or misconfiguration caused the system abnormal, can quickly restore the operating system to the pre-error environment state, thereby reducing the waiting time for the reinstallation of the system (installing linux operating system on the real machine takes at least 30 minutes at a time).
In recent years, when giving lectures, students will always find a wide selection of experimental environments, such as CentOS, RHEL 6, and TheDebian system, resulting in labor-painstaking, miserable, and particularly speechless every time they are wronged. J ust like you sign up to learn japanese food, the teacher with a willow blade, you have to use a long knife, the result sushi will certainly be cut thin. S mart students in the study will certainly use the same tools and environment as teachers, so that after the problem can first eliminate environmental problems and quickly locate errors, such as technical solid enough, to the production environment will naturally have the ability to choose tools and environments at will. Therefore, in particular, it is recommended that students who have not signed up for the paid training courses offered by Mr. Liu Wei must give full play to their self-study ability, otherwise long-term experimental errors will certainly affect your interest in learning.

VmwareWorkStation 12.0 - Virtual Machine Software (required):
Powerful desktop virtual computer software that allows users to run multiple different operating systems simultaneously on a single host.
It also supports powerful features such as real-time snapshots, virtual networks, drag files, and PXE.
RedHatEnterprise Linux (RHEL) 7.0 - Red Hat Operating System (required):
Produced by Red Hat, an open source software and global service system developer, the most stable and outstanding Linux operating system.
In addition, it is also very depressed, in fact, I had the intention to learn Linux system in junior high school, but at that time the Internet is not convenient, want to install Linux system must buy a CD, and at that time to install Linux system needs at least 6 discs (CD-ROM capacity of about 700MB), hard to buy home after trying to install several times but has been wrong, because do not understand the reasons for reporting errors can only give up. I n 2015 before the Spring Festival cleaning the house and turned out these discs, this time finally found the reason for the error that year, the original is the fifth disc was "scratched", the system-related dependency package was damaged, resulting in the Linux system installation failure. Originally can be accessed a few years earlier Linux system, the result is delayed for this reason, is really depressed and embarrassed, so here must be a harsh reminder to students: "tools ready to check the integrity, do not repeat my mistakes."
