Why use a virtual machine when learning Linux?

Some friends who are new to Linux operation and maintenance believe that to learn Linux, they need to install their own computer as a Linux system or have real server equipment. In fact, beginners can learn Linux operation and maintenance by using virtual machines.

Using virtual machine software to build a Linux learning environment is simple and easy to get started. The important thing is that there is almost no difference between the Linux simulated by the virtual machine and the real Linux.

If you buy a server, it will cost you 10,000 to 20,000 yuan, which is beyond the reach of ordinary friends. It is also loud and consumes electricity. If you use PCs and laptops to build Linux, it will be completely a Linux environment. Not only will it increase the difficulty of learning, but it will also be far different from the actual working environment. It is a bit polar opposite.The working environment of operation and maintenance personnel in enterprises is huge Most of them are managed and maintained by remotely connecting to Linux servers thousands of miles away through SSH tools under Windows desktop systems. Therefore, using virtual machine software to build an environment is very close to the corporate working environment.

If you use a virtual machine to study, as long as the computer configuration is higher, you can open multiple Linux virtual machines at the same time. You can study at any time with your laptop on the way to work or home. If there are multiple real computers and server devices, they cannot be moved. If it is placed in the computer room, the price is too high. It is difficult for most learners to have such resources.

Using the virtual machine system environment, we can set up and change the virtual system at will. We can even format the virtual machine system hard disk, repartition and other operations, and we don’t have to worry about losing useful data, because the virtual machine It is a virtual software running on the system. Any operation on the virtual machine system is equivalent to operating the virtual machine device and system of the virtual machine and will not affect the real data on the computer.

Terminal virtualization is popular because of the significant reduction in maintenance costs it brings - such as reducing the occupied space, reducing the cost of purchasing software and hardware equipment, saving energy and lower maintenance costs. It has more cost-effective advantages than actual terminal equipment. But these are not the only reasons why the education industry and manufacturers have a soft spot for virtualization technology. On the other hand, what we rarely mention is that virtualization technology can greatly improve the security of the system.

So, if you want to learn Linux operation and maintenance but are worried about the equipment, just use a virtual machine to learn steadily. Don't set too many obstacles and thresholds for yourself, which will affect your learning progress.
