Install the CentOS7 tutorial in VirtualBox _virtualbox

When the first contact with Linux, because of the conditions, only in the virtual machine installed Linux system use, because it is small white, climbed a lot of pits. I decided to write a blog about installing Linux systems in virtual machines. One is to consolidate their knowledge, the second is to be able to provide some help to novice friends. I use the VirtualBox virtual machine, install CentOS-7 operating system, the article for beginners only reference, if there are omissions, but also hope that you haihan and correct.

Preparation conditions

Where to fill in the name of CentOS-7, type choose Linux, version choose Other or Redhat. If the CPU is 64 bits, select the 64-bit version, or choose 32-bit version. The choice of memory size does not exceed half the size of the real machine memory, I allocate 2G size here. Check to create the virtual hard drive now, click Create.

File location is your virtual machine after the creation of the location, Linux default in the user's home directory, Windows default on the system disk, if the space is sufficient, the default is good. Not enough, click on the Right folder icon to replace the location. The file size is the size of the hard disk space allocated to the virtual machine, where I assign a 30G hard drive to CentOS-7. Virtual hard disk File type Select VDI, which has dynamic allocation and fixed size on physical disks. The difference is that dynamic allocation will be based on the use of your hard disk space to dynamically allocate the number of hard drives. Fixed size is how much you allocate the hard disk, on a one-time from the hard disk to draw how much space to the virtual machine, the corresponding real hard drive on the reduction of how much size (some netizens say fixed size, performance better). then click Create.

Set the root password here and create a user. The novice does not recommend the use of the system in the root account, so you should create a regular user, I do not demonstrate here. It is said that the root account is the underwear worn outside the man, it in the system has the supremacy of authority, haha. However, high level of authority also means high risk, such as you accidentally executed in the root directory rm-fr/command, hehe, then wait for your system corpse.

Installation complete, click Reboot.
