This article shows the installation process of CentOS7 based on vmware workstations. I will not introduce the installation and configuration of vmware workstations here. The basic process is equivalent to installing a software under windows.

1. Open vmware workstations, File->New Virtual Machine, the following interface will appear, select the "Custom (Advanced)" option, and continue with the next step:

2. This step is by default. Continue to the next step:

3. When the following interface appears, select the "Install operating system later" option and continue to the next step:

4. When the following interface appears, select "linux" for the guest operating system and "CentOS 64-bit" for the version. Continue to the next step:

5. The following interface appears. Enter the custom virtual machine name. It is best to make the virtual machine name self-explanatory. Here is "CentOS7_CDH_bd06". Specify the virtual machine location. Here is "D:\Virtual Machines\ CentOS7_CDH_bd06", then continue with 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 respectively, next step Continue:

7. The following interface appears, specify the memory size occupied by the virtual machine, here is 2048M, continue to the next step:

8. The following interface appears. Select the network connection type. Here, select "Use Bridged Network". You can choose according to your needs during the installation of the virtual machine. The installation wizard has provided relatively standardized instructions for various modes. Here are additional instructions. As follows:

1) Use a bridged network: the virtual machine IP is in the same network segment as the local machine. The local machine and the virtual machine can communicate with each other through IP. When the local machine is connected to the Internet, the virtual machine can be connected to the Internet. At the same time, the virtual machine and the virtual machine can communicate with each other. Other hosts in this network segment can communicate with each other. This mode is often used in server environment architecture.

2) Use Network Address Translation (NAT): The virtual machine can connect to the Internet and communicate with the local machine, but cannot communicate with other hosts in the local network segment.

3) Use host-only mode network: the virtual machine cannot connect to the Internet, communicate with the local machine, and cannot communicate with other hosts in the local network segment.

Continue to the next step:

9. Default, continue to the next step:

10. Default, continue to the next step:

11, Default, continue to the next step:

12, The following interface appears, Enter the virtual machine disk size. The default 20g is generally not enough. It is recommended to set it slightly larger. Here, set the virtual machine disk size to 80G. Continue to the next step:

13. Default, Continue to the next step:

14. Default, click "Finish" to end virtual machine creation:

Localization and software parts do not require any settings. What needs attention is the software selection option. The default value is used this time (i.e. minimal installation, this kind of installation of linux The system does not include a graphical interface) installation. As for other components, they can be installed through yum for later use.

As shown in the picture above, the system part needs to be planned and configured with the red part options in the picture, that is, disk partition planning. In addition, the network & host name options can be modified during the installation process. Modify the host name (the default host name is localhost.localdomain). The specific configuration process is as follows:

Click "installation destination" to enter the following interface, select the 80g hard disk, scroll down to the end, select "i will configure partitioning", that is, customize the disk partition, and finally click done in the upper left corner Carry out disk partition planning:

23. CentOS7 disk partitioning is carried out in the interface below. Here is the preliminary planning:

/boot: 1024M, standard Partition format creation.

/: All remaining space is created in lvm volume group format.

The interface after planning is as follows. Click done to complete partition planning, and click "accept changes" in the pop-up dialog box:

##24. After completing the disk planning, click on the red box in the picture below to modify the operating system host name. Here it is changed to db06 (as shown in the second picture), then click done to complete the host name configuration and return to the main configuration interface:

25.

Click "begin installtion" to proceed with the operating system installation process.

If the password security is not high, such as mine The password here is "oracle", so you may need to click twice to confirm. When the root password is successfully set and returned to the installation interface, we can find that the red warning on the previous user setting interface has disappeared. Compare Figure 1 and Figure 3 below:

27. In the picture below, the operating system installation has been completed. Click reboot to restart the operating system.

28. Log in as root user (i.e. root/oracle) and modify the IP address (vi /etc/sysconfig/network-scripts/ifcfg-ens32):

Press the character key "i" to enter the edit mode and modify the /etc/sysconfig/network-scripts/ifcfg-ens32 file content as follows:

After pressing the "esc" key, enter: wq and press Enter to complete editing the configuration file.
