Installing RHEL AS Version 4 on agam                March 17, 2006

Before, I had Red Hat Enterprise Linux AS version 3 installed.

The only thing agam is being used for today, as far as I know,
is Mike Crom has httpd configured to let the Lisle folks do
their month-end accounting charts.  Go to http://agam/ipn to
see the things one can do.

Here was the state of affairs before installing RHEL AS v4.

Apache Web Server Configuration

 -service httpd status  -> is running

 -Conf file is at /etc/httpd/conf/httpd.conf
    ServerRoot = /etc/httpd                                   (the default)
    DocumentRoot = /var/www/html                              (the default)
    log file dir = logs = /etc/httpd/logs -> /var/log/httpd   (the default)
    cgi-bin directory = /var/www/cgi-bin                      (the default)

  Differences from original apparently include
    From Timeout 120 or 300
    To   Timeout 3600

  In the <Directory /> clause around line 294, change
  from AllowOverride None
  to   AllowOverride All

  In the <Directory "/var/www/html"> clause around line 314, changed
    from Options Indexes FollowSymLinks
    to   Options Indexes FollowSymLinks Includes ExecCGI
         (apparently needed for eg, /var/www/html/ipn/OIPND.pl)
    from AllowOverride None
    to   AllowOverride All
         (apparently needed for /var/www/html/ipn/.htaccess, which contains
               just Options Includes)

   Added (or uncommented) #AddHandler cgi-script .cgi
         (Needed.  There's lots of .cgi scripts in /var/www/cgi-bin)

   All the ErrorDocument 400-506 lines uncommented-out.

Use "perl -MCPAN -e shell" command to acquire and install the above 6 packages
(at least, Date-Calc, the 2 DBD* and MIME-Lite).
Handles prerequisites automatically, so Bit-Vector, Carp-Clan, & DBI may have
been requisites.
Use i to install
    i /DBD:: to search for a package

Three changes to /etc/mail/sendmail.cf to let one send e-mail

- After line 95, add  Djdelphion.com
- At line 101, change from   DS
                        to   DSrelay.int.dialog.com
- After line 145, add 
     # who I masquerade as (null for no masquerading) (see also $=M)
     DMdelphion.com

What I'll need to do

- Tar off
   - cgi-bin's from /var/www/cgi-bin
   - html files at /var/www/html
   - /usr/fleskowitz directory (not shared?)  Define fleskowitz in NIS
   - /usr/mysql-standard-4.1.15-pc-linux-gnu-i686/data

I think all that's needed is Elk's SBYNC.

rpm -qa output?  Anything unusual?

------------------------------------------------------------------------------

MySQL database - see /usr/mysql-standard-4.1.15-pc-linux-gnu-i686

Data database is ls -l /usr/mysql-standard-4.1.15-pc-linux-gnu-i686/data
so just tar this.

IBM's DB2 Client with elk's sbync database defined (although I did see a
nclisle)
  rpm -qa | grep -i db2   ==> shows 17 IBM_db2* packages installed

inst1 = instance name

I'll be getting rid of AFS, so /usr/vice/cache can go, too.

To install Red Hat Enterprise Linux AS v4,

1) Boot first RHEL AS Version 4 CD.

2) Selected - Graphical Install by hitting <Enter>
            - English as my language
            - and "U.S. English" keyboard.

3) To partition the drives correctly,
   a) Go ahead and allow "Disk Druid" to "Automatically partition".  I'll modify that later.
 
   b) Install Linux on sda only, the 34707 MB drive, not the big 560,047 MB drive.
      So I had to unselect sdb.

   c) Yes, "Remove all partitions on sda".

      I changed Disk Druid's partitioning to
                    Mount Point/                        Size
              Device    RAID/Volume    Type    Format   (MB)   Start    End
            ==========  ===========  ========  ======  ======  =====  ======
        LVM Volume Groups
            rootvg                                     34560

             /dev/sda2  rootvg       LVM PV     Yes   34,606      14   4,442

4) "Edit" the eth0 network adapter to NOT "Configure using DHCP"
   and specified its    "IP Address:" as 10.222.211.11
             and its       "Netmask:" as 255.255.255.0
             and its      "Hostname:" to agam.delphion.com
             and its       "Gateway:" to 10.222.211.1
             and its   "Primary DNS:" to 199.221.80.141
             and its "Secondary DNS:" to 199.222.82.28

5) !!! Disabled the firewall ('cause I still don't know how to control it, that's why).

6) Didn't install additional languages.

7) Set "Time Zone Selection" to "America/Los_Angeles".

8) Set the root password.

9) After the first reboot, logged on from another machine, and modified
   .bashrc -> Uncommenting those # alias rm='rm -i'
                                 # alias cp='cp -i'
                                 # alias mv='mv -i' lines
           -> Adding my own customization,
              set -o vi
              alias c='echo \\n\\n\\n\\n\n ... \\n\\n\\n\\n\\n\\n\\n\\n;clear'

              if [ "$TERM" = "aixterm" ]
              then alias rc='echo -e "\033[10;97;101m"'
              else alias rc='echo -e "\033[10;94;106m"'
              fi
   .bash_logout -> Uncommenting that clear line.
   .vimrc -> My own vi customizations

9) On the main console, - accepted their license agreement,
                        - did not create any non-root userids,
                        - Registered with Red Hat Network (RHN), selecting the
                          "Use one of my existing, active subscriptions" option.

10) Configured NTP, pointing to afs1 (10.222.211.37)
    - system-config-date
        Removing the 3 default pool.ntp.org NTP servers, and
        adding afs1.delphion.com (10.222.211.37).

11) Added the NFS-mounted file systems.
    - Add sunas1:/dfs             /dfs                    nfs     soft,timeo=100   0 0
          sunas1:/home            /export/home            nfs     soft,timeo=100   0 0
      to /etc/fstab.
    - mkdir /export /export/home /dfs
    - mount -a

12) Configured up2date to use the AFS directory I have set up,
      up2date-config

    On "Retrieval / Installation" screen,
      1) Check "After installation, keep binary packages on disk"
      2) Set the "Package storage directory:" from its default of /var/spool/up2date,
         to /dfs/software/linux/RHEL_v4_i386/up2date

    Installed latest fixes, which wasn't much.

13) Added eagan.tshmg.com to /etc/resolv.conf file.
