Unix System Administration
Redhat 6.0 Linux Installation
Pre-install Checklist #1
Free hard disk space, 500MB->1GB Partition Magic fips fdisk
Settings of all expansion cards Model/Manufacturer Video chip family Ethernet type and hardware address
Pre-install Checklist #2
Install Method CDROM PCMCIA Harddisk Network-based
NFSHTTPFTP
Pre-install Checklist #3Network Addresses
For DHCP/BOOTP IP addressing, make sure you register your Ethernet address with the network people or put it in the DHCP tables
For Static IP addressing, you’ll need...IP addressNetmaskDefault gatewayDomain nameHostname
Creating A Boot Disk
Boot images (D:\IMAGES) boot.img - standard boot image pcmcia.img - for install from PCMCIA
device bootnet.img - for HTTP, FTP or NFS install
Creating disk DOS - D:\DOSUTILS\RAWRITE Unix/Linux - dd
dd if=/cdrom/cdrom0/images/bootnet.img of=/dev/rfd0c
Disk Partitions
/boot OS Kernel & some other bootstrap files
/ This is where most of your software goes
swap partition Virtual memory support 16MB < swap space size < installed memory If >128MB of memory, use multiple swap
partitions <128MB
Optional Partitions
For multi-user or server-based systems /var - logs and variable data files /home - user home directories /var/spool/mail - incoming e-mail /usr/local - locally installed software /tmp - temporary files
BIOS Limitations on HDs
/boot must be… A IDE HD on the primary controller First IDE HD or SCSI HD at target 0 SCSI HD at target 0 or 1 Completely below cylinder 1023
Sample NFS Install - Part 1
Boot from the bootnet.img disk (you made one right?)
Press enter at the “:” prompt to load the kernel
Select your Ethernet card brand and model (RES.net cards are NE2000 compatible)
Select “probe” for most cards, otherwise you’ll need to specify IRQ, memory, etc.
Sample NFS Install - Part 2
Select “NFS image”Choose your addressing method
BootP and DHCP will get all the info you need
Static IP will ask for IP address, netmask, default gateway and primary nameserver
We will use DHCP to obtain our addressEnter “timon.tcnj.edu” as the NFS serverEnter “/cdrom/cdrom0” as the directory
Installing RedHat 6
The rest of the install should be the same no matter which install method you chose.
You are asked if you want to Install or Upgrade
You given a choose of Installation Class; always choose Custom
Answer the question about SCSI adapters appropriately for your system (we don’t have any)
Using Disk Druid
We will use Disk Druid to configure our partitions /boot - 16MB / - 834MB swap - 32MB /usr/share - 300MB /usr/doc - 150MB
Partition Mounts
Initializing Swap and Formatting Partitions
Select the swap file or files to be formatted. If you have time or have a suspect HD, do the “check for bad blocks during format” too.
Select the Linux partitions you want to format. Remember not to format /home if you want to keep the users’ data
Selecting Packages
Good Luck! (We’ll be installing everything)
Use “Select individual packages” if you need to see the sizes for a “space challenged” system
A dependency check will be done before the install commences
It will also tell you if you don’t have enough disk space
The Actual Install
Go get a six pack and a magazine, this will take a while (1/2 to 1 hour)
Or, go practice something you read in Dr. Brown’s Signal column
Post Install
Configure your mouse PS/2 compatible mice simplest Serial mice are a little more trouble Use /usr/sbin/mouseconfig if you need
to change something after installationConfigure your LAN settings if you’re
on a LAN (not dialup). We will keep current IP configuration.
Post Install #2
Set your timezone Only use “Hardware clock set to GMT” if
you aren’t using another OS on the machine
/usr/sbin/timeconfig can be used after installation to change/fix your timezone settings
Post Install #3
Select the services to automatically start at bootup Disable until you know what your doing
DHCP server (dhcpd)Disable NFS server (nfsd)Disable Samba (smbd)Disable FTP server (ftpd)Disable IPX support
Post Install #4
Configure your printer appropriatelyConfigure authentication
Try to stay away from NIS Always use Shadow Passwords
Create a boot diskette Use in emergencies Use it when Windows F’s up your LILO
LILO
Install LILOLILO is an OS boot loaderChoose method install
Master boot record (MBR)Don’t use if you have NT or OS/2 on the
machine
First sector of root partitionUse if NT, OS/2 or using 3rd party boot loader
like BootMagic or System Commander
Configuring XFree86
Good Luck!Make sure your video card is
supportedHave your monitor manual handy (or
a fire extinguisher for older monitors without a manual)
Use Xconfigurator after installation to change/fix settings
The Last SlideThrow away your Windows 95/98/NT
