These instructions can be used to install and configure RedHat Linux 6.2 on a typical PC. They may need to be tweaked slightly, depending on the exact configuration of your PC.

1. Install Linux
   1. Turn on computer and quickly insert disk 1 of RedHat Linux Professional 6.2
   2. If system fails to boot Linux, insert boot disk into floppy drive and restart
   3. At the boot prompt, press the 'Enter' key
   4. Make the following selections:
      1. Language Selection: English
      2. Keyboard Configuration:
         1. Model: Generic 101-key PC
         2. Layout: U.S. English w/ ISO9995-3
         3. Dead Keys: Disable dead keys

      1. Install: Custom
      2. Check 'use fdisk' only if you want full control over the partition layout
      Note: Only 4 primary partitions are allowed. One of these may be an extended partition, which can contain up to 12 logical partitions. Some older BIOS limitations require that the Linux /boot directory be contained in its own partition which does not extend beyond cylinder 1024. DOS/Windows requires a primary partition from which to boot, and additional drives must be logical partitions.
   7. Add the following partitions (sizes suggested):
      1. /boot 32MB

      7. /scratch 1MB and Click 'grow to fill disk'
   8. Choose partitions to format: accept defaults
   9. Lilo configuration

          1. Horizontal sink: 30-64 kHz
          2. Vertical sink: 50-75 Hz
       3. Video Hardware: (Pick appropriate video card)
       4. Check Customize X Configuration
          1. Click next
          2. Choose 1024 by 768 @ 16 bits per pixel
       5. Click 'Test this configuration'
          NOTE: (Control + Alt + Backspace) exits X immediately
       6. Click 'Next'
   16. About to Install. Click Next, and wait a very long time. A log will be written to /tmp/install.log
   17. Congratuilations, Linux has been installed. Click exit
   18. Insert floppy and make boot disk
   19. Remove floppy and press Enter to reboot

2. Verfify the date and time
   1. Login as root and type "date"
   2. Adjust the date and time if necessary with
      # date mmddhhmmyyyy
   3. Write the new date and time to the system's CMOS clock with
      # clock -w

3. Verify Linux has correctly detected all of your machine's RAM
   1. Login and type "free"; verify that your machine's amount of RAM is correctly reported
   2. If Linux reports less RAM than is installed your system, following instructions

4. Customize Linux
   1. Setup networking correctly. Login and startx to start windows, open a terminal, su to root,
      1. Run linuxconf, navigate to Config: Networking: Client tasks: Basic host information.
      2. On hostname tab, set hostname to <hostname>.
      3. On adapter 1 tab, set primary name plus domain to <hostname.domain>.
      4. Click accept. Click 'Act/Changes'. Click 'Activate the changes'. Quit
      5. Reactivate changes if necessary, then quit.
      6. Test network connectivity by browsing and telnetting to server.
   2. Create useful mount points
      # mkdir /mnt/zip
      # mount -t vfat /dev/hdd4 /mnt/zip
      # ls -alF /mnt/zip
      # umount /mnt/zip
      If the following line is added to /etc/fstab
      

      /dev/hdd4 /mnt/zip vfat noauto,owner 0 0

      then the mount command can be simplified to
      

      # mount /mnt/zip

   3. Scratch directory
      # cd /scratch
      # rm -r lost+found
      # chmod 777 /scratch
      # chmod +t /scratch
      
   4. Configure tcp_wrappers
      # vi /etc/hosts.deny
      Add the line,
      

      ALL: ALL

      # vi /etc/hosts.allow
      Add the line,
      

      ALL: <network>/<subnet_mask>

      where <network> can be determined from

      % ipcalc --network <ip_address> <subnet_mask>

   5. Change to a graphical login
      # vi /etc/inittab
      Change the line
      

      id:3:initdefault:

      to
      

      id:5:initdefault:

5. Install additional packages from Red Hat CD's
   1. f2c
      Obtain f2c-19991109-2.i386.rpm from Linux Power Tools Applications CD-ROM, /redhat/i386. Insert CD-ROM.

      # mount /mnt/cdrom
      # cd /mnt/cdrom/i386
      # rpm -Uhv f2c-19991109-2.i386.rpm
      # umount /mnt/cdrom

   2. g77
      Obtain egcs-g77-1.1.2-30.i386.rpm from Linux installation CD-ROM disk 1, /RedHat/RPMS. Insert CD-ROM.

      # mount /mnt/cdrom
      # cd /mnt/cdrom/RedHat/RPMS
      # rpm -Uhv egcs-g77-1.1.2-30.i386.rpm
      # umount /mnt/cdrom

6. Install update packages from RedHat
   • Option 1: Manually download selected updates and install them

     Visit Red Hat website and determine which RPMS need to be updated:
     http://www.redhat.com/support/errata/index.html

     The bare minimum update must include the following packages (or more recent versions):

     wu-ftpd-2.6.0-14.6x.i386.rpm
     nfs-utils-0.1.9.1-1.i386.rpm

     Earlier versions of the above packages have well-known and widely available remote root access security holes. This list is not guaranteed to be complete, as additional root access security holes may have been uncovered since the time this document was written.

     Create a directory for package updates:

     # mkdir /home/download/RPMS

     Download appropriate RPMS into the above directory. You can check to see whether a package is installed by using the following command:

     # rpm -qa | grep package

     Install the updates using the following command:

     # rpm -Fvh [filename(s)]

   • Option 2: Purchase Official Red Hat CD-ROM and automatically install updates

     # mount /mnt/cdrom
     # cd /mnt/cdrom
     # ./install-updates

     Answer 'y' to all prompts

     If the update fails during the dependency check due to krb5-configs, then this package must be installed manually with
     # rpm -ivh 6.2/krb5-configs*
     and ./install-updates must be run again

     After the update is complete, restart your computer with

     # shutdown -r now

     Note that the root file system fails to unmount during shutdown and is therefore automatically checked upon restart; several inodes have zero dtime and are deleted

     A log of the update may be found in /tmp/update.log, and any error messages or warnings may be found in /tmp/update.err

7. Configure Samba
   # /sbin/chkconfig smb on
   # cd /etc
   # cp -p smb.conf smb.conf.000
   # vi smb.conf, make the following changes

   [global] section Set (uncomment if necessary) workgroup = <workgroup> server string = <hostname> Comment out ; printcap name = /etc/printcap ; load printers = yes Set (uncomment if necessary) guest account = nobody Add browseable = yes Set (uncomment if necessary) security = share Comment out ; log file = /var/log/samba/log.%m Set (uncomment if necessary) max log size = 50 local master = no os level = 0 domain master = no preferred master = no wins support = no wins server = preserve case = yes short preserve case = yes

   Restart Samba web server
   # /etc/rc.d/init.d/smb restart
   

8. Configure Apache
   # cd /etc/httpd/conf
   # cp -p httpd.conf httpd.conf.000
   # vi httpd.conf, make the following changes
   

   Uncomment the section <Directory /home/*/public_html> .... </Directory> Uncomment the line AddHandler cgi-script .cgi Add the lines <Directory /home/*/public_html/cgi-bin> Options ExecCGI SetHandler cgi-script </Directory> To disable directory browsing (Recommended) Search for and delete any instances of "Indexes" within "Options" statement. For example, change Options Indexes Includes FollowSymLinks to Options Includes FollowSymLinks

   Important note: The users home directory must be set to mode 755 in order to access it through the web browser. Accounts created during setup are 700 (?), and are not accessible. To fix this, become root and do a chmod 755 on all /home/user directories.

   Restart Apache web server
   # /etc/rc.d/init.d/httpd restart
   

   Some administrators choose to install cgiwrap so that all cgi cripts run as the user in whose directory they are installed, instead of 'nobody'. If desired, cgiwrap can be installed using the following instructions.
