This article changes slightly, add some instructions, the original link: https://www.cnblogs.com/wcwen1990/p/7630545.html

This article shows the CENTOS7 installation process based on the VMware workstations, which is no longer covered by the VMware workstations installation configuration, and the basic process is the equivalent of installing software under Windows.

1, open the VMware workstations, file-and new virtual machine, the following interface appears, select the "Custom (Advanced)" option, the next step to continue:

2, this step by default, the next step continues:

3, in the following interface, select the "Install the operating system later" option, the next step continues:

4, in the following interface, the client operating system select "Linux", version select "CentOS 64-bit", the next step to continue:

5, appear the following interface, enter a custom virtual machine name, virtual machine name best can do words too literally, here is "centos7_cdh_bd06", specify the virtual machine location, here is "D:\Virtual machines\centos7_cdh_bd06", Then proceed to the next step:

6, the following interface appears, select the number of processors and the number of cores per processor, here are 2 and 4, the next step continues:

7, the following interface appears, specify the virtual machine occupies the memory size, here is 2048M, next continue:

8, appear the following interface, choose the type of network connection, here Select "Use Bridge network", you install the virtual machine process according to the needs of their own choice, the installation wizard has been for various modes of the specification of the description, here are added as follows:

1) Using Bridge Network: Virtual machine IP and native in the same network segment, the machine and the virtual machine can be connected through IP, the local network of virtual machine can be networked, while the virtual machine and the other hosts within the network, this mode is often used in the server environment architecture.

2) Use network address translation (NAT): Virtual machine can be networked, and the local interoperability, and the local network segment of the other host does not pass.

3) Use only the host mode network: Virtual machine can not be networked, and the local interoperability, and the local network segment of the other host does not pass.

Next continue:

9. By default, the next step continues:

10, default, next continue:

11. By default, the next step continues:

12, the following interface appears, enter the virtual machine disk size, the default 20g is generally not enough to use, the recommended setting is slightly larger, here set the virtual machine disk size of 80G, the next step continues:

13. By default, the next step continues:

14. By default, click "Finish" to end the virtual machine creation:

15. After exiting the installation wizard, we can see the virtual machine that we just created in the left column of the virtual machine management interface, and we can see the virtual machine configuration information in the right column:

16, click the "Edit Virtual machine settings" option in the interface, the following interface appears:

17, in the need to specify the "CD/DVD (IDE)" Installation image, remove "USB controller", "sound card" and "printer", and then click OK, follow the above settings after the interface as shown:

18. Click on the virtual machine to enter the CENTOS7 operating system installation process:

19, Virtual machine console appears interface, choose Install CentOS liunx 7, click Enter to continue:

20, follow the prompts to click Enter key to continue:

21, the following interface default choice 中文版, click Continue continue: ( Here you can choose Chinese, the official server is best to choose English, good English please ignore )

22, CentOS7 installation configuration of the main interface as shown, according to the interface display, the following 3 parts of the configuration is explained: (date&time option, only Shanghai time zone )

The localization and software sections do not require any settings, which should be noted in the Sofrware selection option, where the default values (i.e. minimal installation, this installed Linux system does not include a graphical interface) are installed, and for other components, Use Yum to install later. ( requires a graphical interface, you can click Software SELECTION, select the GNOME desktop )

For example, the system section needs to be configured with the Red section option in the diagram, that is, disk partitioning planning, and you can modify the host name in the network & host name option during installation (the default hostname is Localhost.localdomain). The specific configuration process is as follows:

Click "Installation Destination", enter the following screen, select the 80g hard disk, scroll down to the end, select "I will configure partitioning", that is, the custom disk partition, Finally, click Done on the top left to partition your disk plan:

23, CentOS7 partition disk is done in the interface, here first explain the pre-planning:

/boot:1024m, the standard partition format is created.

swap:4096m, the standard partition format is created.

/: All remaining space, created using LVM volume group format.

After the planning interface, click Done to complete the zoning plan, click "Accept Changs" in the popup dialog box:

24, after completing the disk planning, click on the Red box section, modify the operating system hostname, here to DB06 (as shown in the second picture), and then click Done to complete the hostname configuration, return to the main configuration interface:

25, in, in fact, from the 24th step configuration we can find the bottom right corner of the "Begin Installtion" button has changed from the original gray to blue, which indicates that the operating system can be installed, click "Begin Installtion" for operating system installation process.

26, in the user settings need to do is to modify the root user password, click "Root Password", set the password, if the password is not high security, such as my password for "Oracle", then you may need to click 2 times to determine. When the root password setting is successfully returned to the installation interface, we can see that the red warning of the user setting interface disappears before, compared to Figure 1 and figure 3 below:

27, in, the operating system installation has been completed, click Reboot Restart the operating system.

28. Use the root user login (i.e. root/oracle) to modify the IP address (VI/ETC/SYSCONFIG/NETWORK-SCRIPTS/IFCFG-ENS32):

Press the character key "I" into the edit mode, modify the contents of the/etc/sysconfig/network-scripts/ifcfg-ens32 file as follows:

After pressing "ESC" key, enter: Wq carriage return, complete profile editing.

Input: The service network restart command restarts the NIC, takes effect just modified IP address, ping www.baidu.com tests network connectivity.

Well, at this point, the CENTOS7 operating system was installed successfully.
