Virtual machine installation and configuration of Red Hat Enterprise Edition 7.4 operating system and related settings
When installing the Red Hat Enterprise Edition 7.4 operating system, you can follow the steps below to configure and set it up:
- Use VM16.0 to install the software, open the hypervisor, and choose to create a new virtual machine. During the process of creating a virtual machine, select the installation image file of Red Hat Enterprise Edition 7.4, and set the installation path of the virtual machine to the file directory of the D drive (for example: e:\17*****\rhel-025).
2. System allocation requirements:
- The total size is 20G: During the virtual machine creation process, set the size of the virtual hard disk to 20G.
- Memory is 1G: During the virtual machine creation process, set the memory size of the virtual machine to 1G.
- The size of the root directory is 5G: During the installation of Red Hat Enterprise Edition, you can choose to mount the root directory to a partition with a size of 5G in the partition settings.
- The memory swap space size is 2G: In the partition settings, you can create a swap partition and set its size to 2G.
- User directory size is 3G: In partition settings, you can create a user directory partition and set its size to 3G. The size of other directories can be allocated as needed.
3. Configure the business series service desktop: This may be a custom configuration step, and the specific operation method depends on the version of Red Hat Enterprise Edition and related documents. It may involve selecting the appropriate software packages and components to configure the Business Series Services desktop environment.
4. Set the system administrator password to "12345678": After the installation is complete, the system will prompt you to set the system administrator (root) password. In this step, set the password to "12345678".
5. Enter the graphical interface by default and log in to the desktop: by selecting the graphical interface in the startup options of the virtual machine, ensure that the system directly enters the graphical desktop after startup.
6. Open the terminal and modify the configuration file: Open the terminal application in the graphical interface, and set the default startup mode of the system to the console terminal mode by editing the corresponding configuration file. The specific configuration files and modification steps may vary depending on the version of the operating system, and you need to refer to relevant documents.
7. Restart the server; execute the restart command or select the restart option in the graphical interface to make the modification of the configuration take effect.
8. Change the system administrator password to eight "8"s: After the system restarts, use the previously set password "12345678" to log in to the system, and change the system administrator password to "88888888" by changing the password command. Make sure the password takes effect after modification, and restart the server.
9. Enter the user name and password to enter the default character terminal mode: After the system restarts, the system will ask you to enter the user name and password. After entering the corresponding credentials, you will enter the default character terminal mode, and you can perform command line operations in this mode.
10. Shut down the server: Completely shut down the virtual machine by executing the command to shut down the server or selecting the shutdown option.
Please note that the above steps only provide a general operation process, and the specific steps may vary due to different software versions and configuration requirements. When doing the actual operation, it is recommended to refer to the relevant documentation and guides to ensure that each step is done correctly.
