These instructions are specific for (re)installing the current
generation of flxi02 and flxi03 using the SGI 4 way servers but may be
used as a basis for installing new fnalu linux interactive nodes if
necessary.

The 7.1 FnaluInteractive workgroup should automatically do most of the
necessary installation and configuration. The install plan is
therefore:

Note: We are no longer nfs mounting /usr/local from fsun01 so the
admin tools previously contained in /usr/local/admin (specifically
bag, tripup and runtrip) are now accessed from afs via a symlink from
/usr/local/admin to /afs/fnal.gov/admin/FNALU/linux24

All the config files and scripts can be found in:

ftp://linux.fnal.gov/linux/711/i386/Fermi/workgroups/FnaluInteractive/

Pre-Install
-----------

 1) Mark the node down in NGOP

 2) Verify that the previous backup ran successfully.

 3) Verify that the keytab file and ssh keys on fsun02 are up to date

 4) Run the clonedisk script to make a copy of the / partition onto the
    spare disk

Install
-------

 5) touch /etc/nologon

 6) Copy the following directories to a safe location

/var/spool/cron     -  root and usr crontab entries
/var/adm/krb5       -  user keytab files

 7) edit /etc/fstab to remove entries to all local disks except the
    one with / on it (sda).

 8) Shut the machine down and power off

 9) Physically remove all the local disks except the one with / on it
    (sda). The disks are hot plug scsi and can be removed without
    opening the case.

10) Boot the system

11) Copy on the fermi-install rpm and the correct reduced kickstart
    file, edit the reduced kicksart file to set the correct partition
    sizes:
    /			5000MB
    /tmp		1000MB
    /usr/vice/cache	200MB
    swap		2000MB

12) install the fermi-install rpm
    rpm -ivh /root/fermi-install.7.1.1...

13) run: /root/fermiinstall/fermi-install -c -f -k -i host_ip -g
    131.225.68.200 -m 255.255.255.0 -n 131.225.8.120 -r 711 -s linux
    -F reduced_kickstart_file

Post-Install
------------

14) Log in on the console:

kinit brew
pwconv
passwd
cd /etc
scp root@fsun02:/var/adm/CLOG/k/krb5.keytab/$host/krb5.keytab .
scp root@fsun02:/var/adm/CLOG/k/sshd_keys/$host/* .
authconfig --kickstart --enablenis
cp /etc/FnaluInteractive/configfiles/nsswitch.conf .
ln -s /afs/fnal.gov/admin/FNALU/linux24 /usr/local/admin
mkdir /var/tripwire
chmod 700 /var/tripwire
. /afs/fnal.gov/ups/etc/setups.sh
ups installasroot tcsh
ups installasroot bash
ups installasroot perl

15) Copy back the saved directories from step 6, merging the root cron
    with the one installed with 7.1

16) Force install of the e100-2.4.9-31smp-1.8.38-1.i386.rpm drivers
    and then edit /etc/modules.conf to use the e100 driver instead of
    the eepro100 by changing the line

alias eth0 eepro100
    to
alias eth0 e100

    and then add the following line to force 100Mb full duplex

options e100 e100_speed_duplex=4

17) Add the following line to /etc/csh.cshrc to correct the "locale
    collate" problem with the UPS version of tcsh

setenv LC_COLLATE C

18) Add the following symlink to fix the problem with the UPS version
    of pine:

ln -s /usr/lib/libncurses.so  /usr/lib/libncurses.so.4

19) Create the mount points for the scratch disks
mkdir /usr/scratch/sect1
mkdir /usr/scratch/sect2
mkdir /usr/scratch/sect3

    and set the permissions

chmod 777 /usr/local/scratch/sect1
chmod 777 /usr/local/scratch/sect2
chmod 777 /usr/local/scratch/sect3

20) Edit /etc/fstab to mount the scratch disks
/dev/sdc1         /usr/scratch/sect1      ext2    defaults	1 3 
/dev/sdd1         /usr/scratch/sect2      ext2    defaults	1 3 
/dev/sde1         /usr/scratch/sect3      ext2    defaults      1 3 

21) make a backup copy of /etc/sendmail.cf and edit it to change the
    line;
DM
    to
DMfnal.gov
    then run
newsaliases
    this sets up the masquerading of mail addresses

22) Edit /etc/sysconfig/afs to add the BIGSTAT option and make it the
    default:
BIGSTAT="-stat 2800 -dcache 800 -daemons 3 -volumes 70 -nosettime"
OPTIONS=$BIGSTAT

    And edit /usr/vice/etc/cacheinfo to up the afs cachesize to 200MB

23) Shut down the machine

24) Reinsert the disks removed in step 9

25) Boot the machine

Testing
-------

26) /sbin/chkconfig --list
    check that the list of processes is as expected.
    ypwhich
    ypcat passwd
    ypcat auto.master

27) Remove /etc/nologon

28) Login with kerberized telnet, ssh and rsh

29) setup and run
    gcc
    f77
    emacs
    vi
    pine
    netscape

30) mail a test message to brew@fnal.gov for brew and from root to
    check that mail masqerading is working as expected

31) Run /usr/local/admin/bin/tripup -r to update the tripwire database
    for the changed files. Then over the next few days refine the
    tripwire config file to better monitor 7.1

At this point the machine should be a standard FnaluInteractive node.

FLXI02 Extra config:
--------------------

For flxi02 we also need to set up the auger data mirror rsync server.

1) Make sure you have an up-to-date copy of flxi02:/etc/rsyncd.conf

2) Copy rysncd.conf back to /etc/rsyncd.conf

3) Add the following lines to the end of /etc/syslog.conf

# Log rsyncd messages (on local0, see rsyncd.conf) to a file
local0.*                        /usr/auger/control/log/rsyncd.log

4) Add the following lines to the head of /etc/logrotate.d/syslog

# rotate the logs for the auger data rsync mirror
# copied from /etc/logrotate.s/syslog and modified
# Added by Chris Brew 12/10/01
/usr/auger/control/log/rsyncd.log {
       postrotate
           /usr/bin/killall -HUP syslogd
       endscript
}
