Create a virtual machine on VMware (system not installed)
2022-07-05 21:53:00 【Longquan TAIA】
open VMware Software , Then click on the file → New virtual machine , The following window will pop up , Choose typical options :
Click next , The following window will pop up , choice “ Install the operating system later ” Options .
Click next , The following window will pop up , Let you choose the type and version of the operating system to be installed in the virtual machine , here , To install Linux Systematic CentOS7 Version as an example .
Click next , Set the name and storage location of the virtual machine , You can choose any name , Save the location , The default is to save in C A directory on the disk , But it is not recommended to put it in C disc , It can be put in D A directory under the disk ( Such as D:\VMware\CentOS7), Convenient for future management .
Click next , Set the maximum hard disk space of the virtual machine , The default is 20G, I choose to assign 40G As the hard disk space of the virtual machine .
Click next , The following interface pops up , Complete the creation of virtual machine . This interface has a “ Custom hardware ” The button , Click it to set the hardware in the virtual machine , But generally speaking , The default hardware setting is ok . If you need to change the hardware settings , We can also create the virtual machine after , Make flexible settings in the virtual machine interface . therefore , Click here to finish .
After the virtual machine is created , You can go to VMware We can see the virtual machine we just created in the main interface of CentOS7, Here's the picture :
such , Our virtual machine is created . This virtual machine is equivalent to a real computer , But we haven't installed the operating system yet . Before installing the operating system , If necessary , We can flexibly change the hardware settings of the virtual machine ( Such as : Memory size 、 Number of processors 、 Network adapters, etc ). You can click “ virtual machine → Set up ”, To make changes .
The memory size of the virtual machine is allocated by default 1G Space , It is recommended not to exceed half of the memory size of the real machine .
Virtual machine processor settings , It can be compared with your real machine CPU The settings of the processor are consistent . The default setting is : The number of processors is 1, The number of cores of the processor is also 1( Single core processor ). Generally speaking , The default value is OK . Unless you want the performance of the virtual machine to be very good , Change it to the maximum .
The hard disk size of the virtual machine is the hard disk size you just allocated , By default, there is only one hard disk , If necessary , You can add one or more hard drives .
The virtual machine CD/DVD(IDE)( I.e. optical drive ) Set up , The setting of the optical drive is very important , It is related to whether you can successfully install the operating system on the virtual machine later . In the state of the equipment , You can see “ Connected ” Not checked , This is because the virtual machine has not been powered on , After starting up, you must ensure that it is checked , otherwise , The CD-ROM drive will not be detected , There is no way to install the operating system for the virtual machine . Because our real machine has no physical drive ( Physical optical drive ), There is no system CD , So here we choose “ Use ISO Image file ”, Then click on the one on the right “ Browse ” Button , Select the system image file you downloaded ( Such as CentOS-7-x86_64-Everything-1708.iso), Click the OK button .
If you haven't linux System image file , Clickable http://pan.baidu.com/s/1qYESbBA download , Or search Baidu for the download address by yourself .
Network adapter settings of virtual machine , Whether the network connection of the virtual machine is normal , There is no introduction here , I'll talk about it in detail later .
Now? , The virtual machine is created , The basic hardware settings are also configured . In order to prevent problems with the virtual machine in the future , Can quickly return to the initial state , We can use VMware The snapshot function of .
3. VMware The snapshot function of
VMware The snapshot function of can help us save a snapshot state for a certain state of the virtual machine , In order to quickly recover a certain state of the virtual machine in the future . It should be noted that , The snapshot function is just VMware The function of , Actual linux The system does not have this function , If you are not using a virtual machine linux System , You need to pay attention to linux Back up the relevant files of the system .
Click the icon shown in the figure below , You can save a snapshot of the current virtual machine state .
Click the icon shown in the figure below , Snapshots of virtual machines can be managed ( take snapshot 、 Restore the snapshot 、 Delete snapshot 、 Clone snapshots, etc ).
4. VMware The cloning function of
VMware The cloning function of is another very convenient function . It can help you quickly clone a copy of the current virtual machine , And it doesn't need to occupy more disk space .
such as , You need more linux When the system performs server cluster test , You can use the cloning function . If you re create a virtual machine , Then install the operating system , It not only takes a long time , And the new virtual machine will also occupy more disk space . Cloning is different , It can quickly clone a copy of the current virtual machine , And it only takes up tens of megabytes of disk space ( Link cloning is required ). therefore , Cloning function is very convenient and practical .
It should be noted that , The cloned virtual machine is just a copy of the original virtual machine , If the original virtual machine is deleted , The cloned replica virtual machine cannot be used normally .
although , Now we haven't installed the operating system for the original virtual machine , But here we still demonstrate the method of cloning ( Generally, cloning is carried out after the operating system is installed ), Steps are as follows :
Click on VMware The main menu bar “ virtual machine → management → clone ”, Pop up the following window :
Click next , Select clone from “ The current state in the virtual machine ”, Here's the picture :
Click next , Clone method selection “ Create a link Clone ”, Here's the picture :
Click next , Set the name and save location of the new virtual machine .
Last , Click Finish . such , We can do that VMware Main interface , I see two identical virtual machines .
5. Install Linux operating system
at present , We have already created a virtual machine (CentOS7), The hardware settings are also configured , Only need to install the operating system for the virtual machine .
About how to use VMware Install linux Of CentOS System , It will be explained in the next chapter .
