The media-based installer is geared to the novice administrators capabilities; hence, the number of decision points and allowable options is very minimal. Such an installation is referred to as an unattended installation in Windows parlance. The installation server contains on-line copies of the distribution media, a set of answer files that control what parts of the software get installed on the system, and a boot daemon that listens for installation requests on the network.
You can customize the answer files to install the OS and any required applications without operator intervention. This is a much more suitable installation method if you have to install computers instead of 2 or 3. All rights reserved.
UNIX installers are often much more willing to allow custom installations than their Windows counterparts. This generally infers that the operator needs to be more knowledgeable about the specifics of the system to successfully complete the installation process. It also means that unattended installations are not feasible without plenty of advance configuration and planning. A typical Solaris 8 installation requires about 20 minutes of operator interaction, then for the next hour or more no interaction is required.
RedHat Linux installations are similar to Solaris in regards to operator interaction. While MOST UNIX installations often take care of the interactive portion up-front, a few of the installers hold the users hand throughout the installation process much like Windows. Like Windows, these installers require a network-based boot server, rules files that dictate how the installation is performed, and a boot daemon that runs on the server to manage the process.
The Solaris JumpStart package is one such network-based installer. Suns WebStart and the Linux KickStart service are other examples of the automated network-based installer.
Because there is no official standard for these networkbased tools, and each vendor has one or more of these installers, describing all of the current offerings is difficult, if not impossible. Installation Methods Linux Kickstart Linux may be kickstarted from a bootable floppy diskette or from a network-based boot server. The floppy diskette must contain a configuration file named ks.
This file is the Linux equivalent of the Windows answer file for an unattended installation. To perform a network installation, you need to have a DHCP server running on your network. The DHCP server instructs the new system how to contact the boot service machine identified in the ks. Installation Methods The Kickstart process requires a rules file to control the installation. The ks. The format of the ks.
The easiest way to create a Kickstart file is to use the Kickstart configurator utility supplied on the distribution media. To start a Kickstart install, you use a special boot floppy. In either case, you start the boot with the following command. Installation Methods Solaris Network Boot Service Daemon To provide a Solaris installation server, you must build and configure a system that will listen for install requests, and know how to deliver the proper files to the host being installed.
This requires the sysadmin to complete the following two major tasks. Build a server, install the boot server software, and configuration files. Install the binaries to be served on the boot server. Installation Methods Saving Critical Data In the event your installation involves the upgrade from an old version of an OS to a new version, there is another critical point to consider.
What do you do with all of the old files on the system when you get ready to install the new software? If the system is a standalone desktop, and you have a new OS as well as new applications to install , you may not need to worry about saving anything from the old system.
More often than not, however, before an old OS is shut down for the last time there are several files you may wish to save. Installation Methods Servers often present an even bigger challenge when you are upgrading an OS. For instance, because you may not have to change the partitioning to load a new OS, it would help to know how the disks on the system are currently partitioned.
Printing out information regarding current disk partitions may be very helpful information during the upgrade. Saving the password file, NIS name, server maps, user files, and other critical information before you begin the installation procedure is always strongly recommended. Again, err on the side of caution, and perform a full file system backup before you begin the upgrade. Nine out of ten times you will be glad you spent the extra time to do so. Summary Installing an OS is a huge undertaking.
There are no set formulas for how it should be done. Early steps in the planning should include checking that the new software will run on the hardware. Determination of the type of installation, homogenous server, heterogeneous server, standalone system, thick client, or thin client should also be addressed before beginning the installation process. System types to be supported and the intended use of the system must also be factored into installation planning.
Application availability should be checked, and rechecked. If mission-critical applications are not available for the OS to be installed, you may have to change your plans. Summary Because the administrators approach to OS installation is critical to the success of the system, allocating some time for experimentation can be extremely useful.
Plan an installation and then implement the system based on initial planning sessions. As the first installation is performed, keep copious notes on the process, and any surprises encountered.
Once the system is up and running, inspect everything to make sure no critical information was forgotten. When you think the test installation is a success, wipe out the installation and go through the process a second time.
When it comes to installing an OS, practice makes perfect. Open navigation menu. Close suggestions Search Search. User Settings. Skip carousel. Carousel Previous. Carousel Next.
