[Day1] VMware software installation

First, the main task is software installation: VMware;

Second, VMware installation precautions

1. The VMware installation is best installed on another disk, Do not install it on the C drive, Avoid the computer due to the content of the C driveToo much will cause lag.

2. When you need to store software resources, it is best to store it in non-C drive

3. Precautions for creating a new virtual machine

1. Create a new virtual machine

2. In the new virtual machine wizard, after entering the secret key, check Custom, and select the installation source of the virtual machine. Here I use

3. Check the downloaded centos image file

4.The time modification is the same as the local time to avoid errors when connecting

5. Click to configure memory, If you need to manually configure it yourself, check I would configure partitioning

6.Note the size of the swap cannot be larger than the memory size (the memory here is 1G, so the size of the swap is 2G)p>

7. Click [Reboot] after completion, log in after restarting, as shown below after success

8. Only one virtual machine can be stored in a file, otherwise problems may occur

Fourth, VMWare provides three working modes

1. ①ridged (bridged mode),

      ②NAT (Network Address Translation Mode)

3 host-only (host mode).

After installing the virtual machine, you can see two more network cards in the network connection.As shown below.

2. Mode introduction

①ridged (bridged mode) In this mode, the virtualized operating system of VMWare is like an independent host in the local area network, which can access any machine in the network. The virtual system and host using bridged modeThe relationship between machines is like two computers connected to the same Hub.In order for them to communicate with each other, you need to configure the IP address and subnet mask for the virtual system, otherwise communication will not be possible.

2 NAT (Network Address Translation Mode) In some special network debugging environments, it is required to separate the real environment from the virtual environment, then you can use the host-only mode.

③host-only (host mode) Use NAT mode to access the Internet in a virtual system.The TCP/IP configuration information of the virtual system in NAT mode is provided by the DHCP server of the VMnet8 (NAT) virtual network and cannot be modified manually, so the virtual system cannot communicate with other real hosts in the local area network.The biggest advantage of using NAT mode is that it is very simple for the virtual system to access the Internet, you do not need to perform any other configuration, only the host machine can access the Internet.
