Creating a CentOS 7 Virtual Machine
Before you begin:
Make sure that vSphere client is installed on your workstation.
Within vSphere, there are numerous ways to perform a particular task. The following example illustrates one such method. You can use the procedure that suits your network deployment effectively.
To create a new CentOS 7 STIG’d VM instance of CTPView server on an ESXi Server:
- Copy the CentOS 7 ISO file (centOS-7-x86_64-DVD-1804.iso) to the ESXi datastore. The CentOS 7 ISO can be downloaded from http://vault.centos.org/7.5.1804/isos/x86_64/.
- Start the vSphere client and enter the ESXi server IP address and your login credentials.
- Start the wizard to create a new virtual machine. Select File > New > Virtual Machine.
- Select the configuration as Typical and click Next.
- Enter a name for the VM. For example, CTPView_9.0R1.
- Select the datastore (with at least 80 GB free space) and click Next.
- Select Guest OS as Linux and version as Other Linux (64-bit), and then click Next.
