admin13 April 2024Last Update :

Prerequisites for Installing CentOS 7 in VMware

Before diving into the installation process, it’s essential to ensure that you have all the necessary components and understand the requirements. Here are the prerequisites:

  • VMware Workstation/Player: Ensure you have VMware Workstation or VMware Player installed on your system. These are virtualization applications that allow you to run multiple operating systems simultaneously.
  • CentOS 7 ISO Image: Download the CentOS 7 ISO image from the official CentOS website. Choose the appropriate version based on your system architecture (32-bit or 64-bit).
  • System Requirements: Your host system should meet the minimum hardware requirements for running a virtual machine, such as a multi-core processor, sufficient RAM (at least 2GB for CentOS), and enough free disk space (20GB recommended for the CentOS VM).
  • Internet Connection: An internet connection is required to download the necessary files and updates during the installation process.

Setting Up a New Virtual Machine for CentOS 7

To begin the installation, you need to set up a new virtual machine within VMware.

  • Open VMware Workstation/Player and click on Create a New Virtual Machine.
  • Select Typical (recommended) and click Next.
  • Choose I will install the operating system later and click Next.
  • Select Linux as the guest operating system and choose CentOS 7 from the version dropdown menu. Click Next.
  • Name your virtual machine and specify the location where you want to store the VM files. Click Next.
  • Specify the disk size for the virtual machine. A minimum of 20GB is recommended. You can also select whether to store the virtual disk as a single file or split it into multiple files. Click Next.
  • Before finishing, click on Customize Hardware… to adjust the VM’s memory, processors, and other hardware options according to your preference.
  • Click Close after customizing the hardware, then click Finish to create the virtual machine.

Mounting the CentOS 7 ISO Image to the VM

With the virtual machine created, the next step is to mount the CentOS 7 ISO image so that it can be used to install the operating system.

  • Select the newly created CentOS VM and click on Edit virtual machine settings.
  • Go to the CD/DVD (SATA) option in the hardware tab.
  • Choose Use ISO image file: and browse to locate the downloaded CentOS 7 ISO file.
  • Select the ISO file and click OK to save the settings.

Installing CentOS 7 on the Virtual Machine

Now that the ISO is mounted, you can proceed with the actual installation of CentOS 7.

  • Start the virtual machine by clicking on Power on this virtual machine.
  • Once the VM boots up, you’ll see the CentOS 7 welcome screen. Select Install CentOS 7 and press Enter.
  • The installer will load, and you’ll be prompted to select your language preference. Make your selection and click Continue.
  • You’ll be taken to the Installation Summary screen. Here, you’ll need to configure various settings like Date & Time, Keyboard, Language Support, Installation Source, Software Selection, Installation Destination, Network & Hostname, and Security Policy.
  • Under Installation Destination, make sure to select the correct hard drive and choose whether you want automatic partitioning or manual partitioning. For most users, automatic partitioning is sufficient.
  • In the Network & Hostname section, enable the network interface and set your hostname if desired.
  • After configuring all settings, click on Begin Installation.
  • While the installation proceeds, set your root password and create an additional user if needed.
  • Once the installation completes, click Reboot to restart the virtual machine.

Post-Installation Setup

After rebooting, there are a few post-installation steps to finalize the setup of your CentOS 7 environment.

  • Upon restarting, you may be presented with the Initial Setup screen. Complete any remaining settings like accepting the license agreement.
  • If you’ve created an additional user, log in with those credentials. Otherwise, log in as the root user with the password you set during installation.
  • It’s recommended to update your system immediately after installation. Open a terminal and run the following command:
    yum update
  • Once the updates are complete, you can install additional software, configure services, or start deploying your applications on the CentOS 7 virtual machine.

Troubleshooting Common Installation Issues

Sometimes, you might encounter issues during the installation process. Here are some common problems and their solutions:

  • If the virtual machine does not boot from the ISO image, check the VM settings to ensure that the CD/DVD drive is connected and set to use the ISO image file.
  • In case of errors related to insufficient memory or disk space, adjust the VM settings to allocate more resources.
  • If you experience slow performance, consider enabling virtualization technology (VT-x/AMD-V) in your BIOS settings, which can significantly improve VM performance.
