Server provisioning is nothing but installs the Linux or UNIX like operating systems automatically. One can install actual operating systems, device drivers, data, and make a server ready for network operation without any user input. Typically you select a server from a pool of available servers, load the operating systems (such as RHEL, Fedora, FreeBSD, Debian), and finally customize storage, network (IP, gateway, bounding etc), drivers, applications, users, ssh keys Open Source Linux Server Provisioning Softwareand more. Using the following tools, you can perform automated unattended operating system installation, configuration, set virtual machines and much more. The following open source Linux server provisioning Software can be used to install a lot (say thousands) of Linux and UNIX systems at the same time.
Often I need to roll out CentOS/RHEL/Suse/Ubuntu/Debian Linux to a set of the server with precisely same or different hardware configuration. I need Linux automatically roll out without any intervention from anyone.
From the official Redhat guide:
Many system administrators would prefer to use an automated installation method to install Red Hat / CentOS / Fedora Linux on their machines. To answer this need, Red Hat created the kickstart installation method. Using kickstart, a system administrator can create a single file containing the answers to all the questions that would normally be asked during a typical Red Hat Linux installation. Kickstart provides a way for users to automate a Red Hat Enterprise Linux installation.
Kickstart Configurator allows you to create or modify a kickstart file using a graphical user interface, so that you do not have to remember the correct syntax of the file.

2. Fully Automatic Installation (FAI)
FAI is a non-interactive system to install, customize and manage Linux systems and software configurations on computers as well as virtual machines and chroot environments, from small networks to large-scale infrastructures and clusters. It is a tool for fully automatic installation of Debian and other Linux Distributions such as Suse, Redhat, Solaris via network, custom install cd, or into a chroot environment. Some people also use it to install Windows.
- Installs and updates Debian, Ubuntu, SuSe, RHEL, CentOS, Fedora, Mandriva, Solaris, etc
- Centralized deployment and configuration management
- Integrated disaster recovery system
- Easy set up of software RAID and LVM
- Installs XEN domains, VirtualBox and Vserve
- Every stage can be customized via hooks
- Full remote control via ssh during installation
Cobbler is a Linux provisioning server that centralizes and simplifies control of services including DHCP, TFTP, and DNS for the purpose of performing network-based operating systems installs. It can be configured for PXE, reinstallations, and virtualized guests using Xen, KVM or VMware. Again it is mainly used by Redhat and friends, but you can configure a PXE server to boot various non-RPM boot images such as Knoppix and other flavors of Debian such as Ubuntu.
There is also a lightweight built-in configuration management system, as well as support for integrating with configuration management systems like Puppet. Cobbler has a command line interface, a web interface, and also several API access options.
See the official Cobbler project home page and wiki for more information.
From the official website:
Spacewalk is an open source (GPLv2) Linux systems management solution. It is the upstream community project from which the Red Hat Network Satellite product is derived. Spacewalk manages software content updates for Red Hat derived distributions such as Fedora, CentOS, and Scientific Linux, within your firewall. You can stage software content through different environments, managing the deployment of updates to systems and allowing you to view at which update level any given system is at across your deployment. A clean central web interface allows viewing of systems and their software update status, and initiating update actions.
- Inventory your systems (hardware and software information)
- Install and update software on your systems
- Collect and distribute your custom software packages into manageable groups
- Provision (kickstart) your systems
- Manage and deploy configuration files to your systems
- Monitor your systems
- Provision and start/stop/configure virtual guests
- Distribute content across multiple geographical sites in an efficient manner.
See the official project website for more information.
From the official website:
openQRM is the next generation, open-source Data-center management platform. Its fully pluggable architecture focuses on automatic, rapid- and appliance-based deployment, monitoring, high-availability, cloud computing and especially on supporting and conforming multiple virtualization technologies. openQRM is a single-management console for the complete IT-infra structure and provides a well defined API which can be used to integrate third-party tools as additional plugins.
- Complete separation of “hardware” (physical servers and virtual machines) from “software” (server-images)
Support for different virtualization technologies
- Fully automatic Nagios configuration (single click) to monitor all systems and services
- High-availability : “N to 1” fail-over
- Integrated storage management
- Distribution support – openQRM 4.x comes with a solid support for different linux distribution like Debian, Ubuntu, CentOS and openSuse. A single openQRM server can manage the provisioning of servers from those different linux distributions seamlessly.
See the official project website for more information.
Foreman is a free and open source software for provisioning and configuring physical and virtual servers. It gets integrated very well with configuration management software such as Puppet, Chef, Salt and other solutions through plugins. From the project home page:
Foreman is a complete lifecycle management tool for physical and virtual servers. We give system administrators the power to easily automate repetitive tasks, quickly deploy applications, and proactively manage servers, on-premise or in the cloud. Bare metal, Amazon EC2, Google Compute Engine, OpenStack, Libvirt, oVirt, VMware, and many other providers allow you to manage a hybrid cloud through Foreman.
- RBAC and LDAP integration
- CLI access
- Manage a hybrid cloud
- A pluggable architecture allows you to extend Foreman in almost any direction
DIY: Provisioning Server
You can build your own server using PXE, TFTP server, and DHCP software. PXE allows you to boot up a system and have it automatically get an IP address via DHCP and start booting a kernel over the network. See the following articles for more information:
- AutoYaST – A system for installing one or more openSUSE Leap/Suse Linux systems automatically and without user intervention, using an AutoYaST profile that contains installation and configuration data.
- Crowbar – Transform your bare-metal into an OpenStack Cloud in hours. Support for CEPH, High Availability, SSL and unattended installation included.
There are many proprietary software solutions available to automate the provisioning of servers, services and end-user devices from vendors such as BladeLogic, IBM, or HP. But open source software gives you more freedom to automate the installation of the Linux server. Some of the above software support UNIX and Windows operating systems too.
I’m wondering if you use server Provisioning Software regularly. Drop your discussion below and share what works for you in the comments.
