![]() ![]() ![]() ![]() In the Network settings, set the adapter to 'Bridged'.(Regardless, My VirtualBox still asks to map a CD-ROM when the host first boots, but you can ignore that message by clicking the Cancel button. You can disable CD and floppy completely. Make sure to set the host to boot from Hard disk first, then PXE.The disk partitioning section of the VirtualBox settings will need an 8 Gb disk at a miminum (larger is OK, but extra space won't get used with the kickstart file directives below). What does make a difference (at least for the procedure below) is that the disk is at least 8Gb is size. It makes no difference at all whether the disk is dynamic, or fully allocated when the VM is created.That said, you will be root, so read and understand each command below before you type it in at the keyboard.Ĭonfiguring the client is largely left to the reader, but I will provide some hints, particularly as they apply to VirtualBox. As such, it is likely not yet in production, so the standard to which we work is different. Consider that it is bad practice to manage a server as root, but in this case, I consider this activity to be standing up a server, rather than operational maintenance. We will be performing the entirety of this installation as the root user. Instead, I would recommend restarting each service as you complete the configuration changes for that service. If selinux is already disabled when you begin, a reboot is not required. Rebooting is only necessary at the end in the event that we change the status of selinux. Simplicity is important, but reliability is non-negotiable. There is one exception to this rule: In the event that a task may be completed in multiple phases, and the outcome of that task is more reliable in a later phase, we will perform that task later, rather than earlier. Each phase handles only the minimum tasks required to get us to the next phase. There will be multiple phases: OS Deploy, OS Configuration, Application Deploy, etc. The build philosophy is rather straight-forward. In this way, once the end-to-end deployment process completes, a server should be able to do a final boot, and be ready to start work. For example, all home, and application directories are made available via NFS. Anticipating further automation in the future after the base OS is installed, we don't want to redesign our environment as we go, so we're making some decisions now that may seem overkill, or otherwise not necessary. Manual attendance will still be required to select the appropriate image, perform final networking configurations, and similar tasks. This tutorial covers strictly setting up the PXE environment and repositories so we can deploy a server. This will guide many of the configuration decisions below.ĭeployment Server: a CentOS 7 server with the address: 172.16.1.1/16, and hostname of 'deploy'. Here's what the build environment looks like. On the deployment server, have DNS (bind) and DHCP configured and running. Set up a deployment server on CentOS 7 for Linux hosts. ![]()
