You could also try using the IP address by doing a 'nslookup' or 'host' command to find the current IP address of lnxinstall. The default partitioning scheme used by the the other options is not suitable for use in the SLAC environment. The table below shows suggested partitioning schemes for two different sizedisks, representing typical sizes of disks available on older hardware stillin service here at SLAC.
Newer systems usually have substantially largersystem disks. Make sure to give Linux at least a 9 GB root partition. If your root partition is less than about 9 GB, you should omit installingsome of the software package groups recommended below, in order to allowroom for future upgrades and security patches. Similarly, if you installmore package groups than suggested below, you will probably need a largerroot partition -- perhaps GB if you install nearly everything.
Smallroot partitions can make it difficult or impossible to install requiredsecurity patches later on. Systems that cannot apply required securitypatches in a timely fashion may be denied access to the SLACnetwork. If possible the root partion should be at least 20 GBfor modern machines with GB and larger disks.
You should also create a swap partition at least as large as the memory twice the main memory is a good rule of thumb for the size of the swappartition. Always choose to format your Linux partitions. You should not allocateany partitions on the system disk for permanent data. Because of the largesizes of currently available disks, you may be strongly tempted to ignorethis warning.
However, it is very risky to do so, because:. If you need additional permanent space,please contact [email protected] ; we will do our best to help youacquire reliable, backed-up storage at a reasonable cost. If you ignore this warning, it will be your responsibility to saveand restore your data the next time your system needs to bere-installed.
Note that partition names and numbers, and the order of the partitions, areassigned automatically. Also, the actual sizes ofallocated partitions may vary a little bit from what you request in theGUI interface.
This may make it difficult to allocate every last blockon the disk. As stated by the installer, 'The default installation of Red Hat EnterpriseLinux is a desktop install. Don't worry too much about getting every package you might ever want -- youcan always add additional packages later. Once complete, you'll be presentedwith a 'Congratulations' screen. The final installation screen has a 'reboot' bottom on the right corner.
Again, makesure to remove any CDROM left in the drive from the initial boot of theinstallation program. The first time you boot your newly-installed system in the graphicalrun level run level 5 the Red Hat Welcome screens mayautomatically run. If you are planning to taylor your system you can skip most or all ofthese steps -- they are either unneeded or will be handled by taylor. The welcome screens are intended for stand-alone systems andguides you through a number of first time system administration taskssuch as:.
If you plan to taylor the system, you do not need to create a local account. Please do not. For the Create User screen 'Forward' button with no additions or adjustments.
You'll need to confirm you want to continue without a user account. On the next screen, you'll click on 'Other.. You'll see messages related to being logged inas root, and how it's not ideal, but this okay for this one time. You'll alsosee missing entitlements messages. It can be runafter the Red Hat installation program to automatically configure your newsystem to be integrated into the SLAC environment. It normally installs acronjob which will maintain your system automatically. If you don't have this file the first time you run Taylor, itwill install one with a reasonable set of defaults.
However, you may wantto set some of these options before you run Taylor the first time, since the root password you set during installation will otherwise beoverridden at this point. If your machine was previously taylored, you will most likely want torestore most or all of the options from your old taylor.
If you are not sure, omit this option or check with net-admin or your DesktopAdmin. In particular, this file includes commentedout examples examples showing how to:.
First get to a terminal prompt from the GUI by selecting from the top leftof the menu bar 'Applications',then 'Systems Tools' and lastly 'Terminal'. We highlyrecommend that you use the central one.
Taylor will probably take several minutes to complete its work. If there isan error and you can see how to fix the problem, it is safe to rerun taylor afterward.
If you have an error you cannot understandor fix, send email to unix-admin to request help. If possible, paste the errormessages from Taylor into the email. Some users may also wantto access other central NFS file servers from their Linux workstations.
There is asimple NFS Access form for this purpose if you do not need any superuser privileges on themachine. Replace filename. This is important because the download link in the Customer Portal contains extra characters which curl would otherwise use in the downloaded file name, too.
Finally, use another single quotation mark after the last parameter, and press Enter to run the command and start transferring the ISO image. The single quotation marks prevent the command line interpreter from misinterpreting any special characters that might be included in the download link. Example 2. Downloading an ISO image with curl The following is an example of a curl command line:.
Note that the actual download link is much longer because it contains complicated identifiers. If your Internet connection does drop before the transfer is complete, refresh the download page in the Customer Portal; log in again if necessary. Copy the new download link, use the same basic curl command line parameters as earlier but be sure to use the new download link, and add -C - to instruct curl to automatically determine where it should continue based on the size of the already downloaded file.
Resuming an interrupted download attempt The following is an example of a curl command line that you use if you have only partially downloaded the ISO image of your choice:. Optionally, you can use a checksum utility such as shasum to verify the integrity of the image file after the download finishes.
All downloads on the Download Red Hat Enterprise Linux page are provided with their checksums for reference:. You can also use the installation program to verify the media when starting the installation; see Section Use it to create a bootable USB drive; see Section 3.
