4 Welcome! Plexxi Control runs as an application in a Linux environment. You install Plexxi Control on a Linux-based computer that can support the Apache Tomcat server and the PostgreSQL database application. Installation Components CentOS 6.5 Linux for Plexxi Control Plexxi Control application. Ensure your version of Plexxi Control is compatible with the version of Plexxi Switch you ll be managing. Process Overview For a bare metal install, contact Plexxi Support with your hardware configuration information for assistance with the installation. 1. Obtain the Linux for Plexxi Control ISO image and the Plexxi Control install file from the Plexxi Support site or from your Plexxi representative. 2. Install Linux for Plexxi Control. (CentOS 6.5). 3. Install Plexxi Control. Requirements Review the following system requirements before you start the installation. Minimum System Requirements The system requirements are for both VM and hardware installs. Processor: Quad core Memory: 8GB RAM minimum Hard drive: 200GB disk space Supported Hardware Dell PowerEdge R420. Contact your Plexxi representative or Plexxi Support if you want to install on other hardware. Some disk/raid controllers could require additional drivers and/or manual install steps. VMware Hypervisor Install Plexxi Control is supported in a virtual environment on VMware ESX 5.x hypervisors. Contact Plexxi Support if you want to install on a different hypervisor. Review the following recommended CPU and memory reservations to ensure Plexxi Control gets the resources it needs. Do not oversubscribe the hypervisor memory and CPU resources to ensure available resources at all times. Memory: Reservation: 8GB; Shares: Normal; Limit: Unlimited CPU: Reservation: 4 CPU Ghz equivalent; Shares: Normal; Limit: Unlimited (for example 8.8 Ghz for 4 core aggregate with 2.2 Ghz cores) 4

5 To access the reservation settings: vcenter VM->Edit Settings->Resources tab vcenter VM->Manage Resources For other installation on other hypervisors, Plexxi recommends following the same requirements. Network Settings Determine the following network settings: DHCP: The installer supports DHCP configurations out-of-the box with no additional configuration required. However, you might want to add a DHCP reservation and/or DNS hostname entry on your DHCP/DNS server(s). Static IP: Ensure you have your static IP address, netmask, default gateway, and DNS server information. You can enter this information when prompted by the installer or supply it as boot options to the installer. Hostname: You can either pass a specific hostname to the installer as a boot option or ensure that your DNS server has the hostname entry for your DHCP reserved or static IP address. Offline or Online Install Determine if you want to do an online (network-based, Internet access required) or offline (self-contained, no network access required) install. If your installation needs to be completed in an offline environment, you will need to get a copy of the Plexxi Control install that you can put on a USB stick or CD/ISO image. Security Considerations The Plexxi Linux for Plexxi Control install disables SELinux and SSH access to the root account by default and prompts you to enter a new root password on the first boot. You should also take the additional measures required by your system administrator to secure the installation. See the Red Hat Enterprise Linux 6 Security Guide for more information: US/Red_Hat_Enterprise_Linux/6/html/Security_Guide/ 5

6 Quick Start Online Install In a quick start installation, you perform an online automatic install of the Linux for Plexxi Control operating system and then install Plexxi Control. Linux for Plexxi Control 1.

The system reboots and the Change password for user root prompt appears. When the Plexxi Control server/vm first boots up after the Linux for Plexxi Control installation, you are prompted to change the root password. Until this step is completed, the Plexxi Control server will not be fully functional. 7. Enter a new password. The Select Action window appears. 8. Press Tab to highlight Save&Quit. The Authentication Configuration window appears. Configure device (optional see Configure Device) Configure DNS (optional see Configure DNS) Save&Quit or Quit both of which lead to the Authentication Configuration window.

7 Plexxi Control With Linux in place, you can now install Plexxi Control. 1. Determine the version of Plexxi Control software you need to install. For example Log in either on the console or remotely via SSH as username plexxi with the default password plexxi. 3. Run the install-plexxi-control <version> script. For example: sudo install-plexxi-control When prompted Enter Y to proceed and press Enter. The installation process starts. Install Linux for Plexxi Control When you install Linux for Plexxi Control, you choose one of the automatic install options. No install process is totally automatic; at the least you must accept two license agreements. Automatic Install The Linux for Plexxi Control installer automates most of the Linux OS install for you by completing the installation screens behind the scene. You are prompted for license term acceptance and possibly static IP address information depending on the install option you chose. Advanced installation methods require the most interaction and require assistance from Plexxi Support. Avoiding Automatic Reboot Automatic boot/reboot kicks off when you: Launch the installer. The Automatic install (recommended) option is highlighted by default and the boot countdown is active when you first launch the installer. Change focus to a different option to stop the boot countdown. Navigate to the Advanced installation menu and choose Return to the main menu. The Automatic install (recommended) option is highlighted by default and the boot countdown is active when you return to the main menu. Change focus to a different option to stop the boot countdown. Did not eject your ISO image from the CD device and/or set your startup device to Hard drive if required by your install environment. Otherwise your VM could boot back into the installer menu again. 7

8 Install Options You chose from the following options to install Linux for Plexxi Control. The first two automatic options are the same for both the online and offline install. Advanced installation options differ slightly between offline and online. Automatic with DHCP Automatic with static IP address Advanced options that require Plexxi Support assistance. The offline install includes an experimental option to install from a USB stick, which should only be undertaken with the assistance of Plexxi Support. Offline Install You have chosen to do an offline install because you do not have a network connection. You have the correct package from Plexxi, for example pxctl-offline iso.

If your installation needs to be completed in an offline environment, obtain a copy of the Plexxi Control install from your Plexxi representative or Plexxi Support. The Plexxi Control installer uses a number of core Linux utilities, such as sudo and yum. Some of the output and prompts displayed during the installation are generated by these utilities. For example, best practice reminders are generated by sudo the first time you use sudo to execute a command. Online Help You can access online help by entering the following syntax: install-plexxi-control --help Install 1. Determine the version of Plexxi Control software you need to install.
