Today, the editor will share with you the relevant knowledge points about how to install CentOS7 in virtualbox. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article.

Preparation condition

* the virtualbox virtual machine has been installed on your real machine. The specific installation method can be Baidu.

* go to the Internet to download the image of centos-7.

1. Create a virtual computer in a virtual machine

As shown in figure (1) Click the New button to start a new virtual machine

Enter centos-7 in the name, select linux for type, and select other or redhat for version. If the cpu is 64-bit, choose the 64-bit version, otherwise choose the 32-bit version. The choice of memory size should not exceed half of the real machine memory. I allocate 2g here. Check to create a virtual hard disk now and click create.

The file location is the location where your virtual machine is created. Linux is placed in the user's home directory by default, and windows is placed on the system disk by default. If there is enough space, it is fine by default. Not enough, click the folder icon on the right to change location. The file size is the amount of hard disk space allocated to the virtual machine, and here I allocate 30g of hard disk to centos-7. The file type of the virtual hard disk is vdi, which is dynamically allocated and fixed size on the physical disk. The difference is that dynamic allocation dynamically allocates the number of hard drives according to your hard disk space usage. Fixed size is how much hard disk you allocate, how much space is set aside from the hard disk to the virtual machine at one time, and the corresponding real machine hard disk will be reduced in size (some netizens say that the fixed size has better performance). Then click create.

Now the virtual computer has been created, but it can't be started yet, and some simple settings need to be made.

Open the network in the network and hostname, and the hostname is fine by default, even if you want to change it.

Now click to start the installation

Set the password for the root user here, and create a user. Novices are not recommended to use the system under a root account, so they should set up a regular user, and I won't demonstrate it here. It is said that the root account is the man who wears his underpants outside, it has the supreme authority in the system, . However, high permissions also mean high risk, for example, if you accidentally execute the rm-fr / command in the root directory, hey, then wait for your system to be collected.

Installation is complete, click restart.

Restart appears this, is the initialization information of centos-7, enter 1 enter, then enter 2 enter, and then enter Q enter.

If you create a normal user, the user name will be listed here. If not, click not listed and enter the root user name and password to log in.

Enter the system
