Solaris Installation Procedure
This sections describes Solaris 10 installation procedure for CLON cluster (Sparc-, Xeon- and Opteron-based machines).
You will need 5 CDs 'Solaris 10 Software' (or one DVD) and one DVD 'Software Companion'. Download CDs or DVD image from http://www.sun.com. If you do not have DVD-ROM, you can mount iso image of the Companion after system itself is installed (see instructions below).
Boot from CD1. Several questions will be asked, for example for clonxt2:
hostname: clonxt2 IP address: 129.57.167.108 mask: 255.255.255.0 (will be written to /etc/netmasks) route: 129.57.167.99 (others: 129.57.68.100, 129.57.69.1, 129.57.160.1, will be written to /etc/defaultrouter) services: choose DNS domain name: jlab.org DNS servers: 129.57.167.5, 129.57.167.14, 129.57.32.100 search domain: jlab.org, acc.jlab.org (will be written to /etc/resolv.conf)
Partition disk: if only one disk exist, set 12GB for 'swap', 40GB for system '/', mount the the rest as '/space' (clon05 and others with smaller disks: 4096MB swap, 15GB /). If 2 disks exists and there is no intension to use second one, make it /space and use whole first disk for / and 12G swap. Sun has its own disk name scheme, for example c1t0d0 means ... .
NOTE: 'format' command shows all disks.
Follow instructions on screen and finish installation.
After installation is finished do following (use /opt/sfw/bin/emacs to edit files):
/etc/default/login: comment out CONSOLE=/dev/console /etc/ssh/sshd_config: PermitRootLogin?: 'no' - change to 'yes' svcadm restart /network/ssh (to show all services, type 'svcs')
From now on 'ssh root@clonxt2' is possible from remote host.
Install software from CD 'Software Companion'. Use it's README and follow instructions. If you want to mount iso image use loopback file driver lofi, for example:
lofiadm -a /root/sol-10-u3-companion-ga.iso /dev/lofi/1 mount -F hsfs -o ro /dev/lofi/1 /mnt
Image will be mounted as /mnt. To unmount do following:
umount /mnt lofiadm -d /dev/lofi/1
To configure NIS do following:
1. Create /etc/defaultdomain with one line containing 'CCCHP'
2. Add to /etc/hosts all hosts to be used in 'ypinit -c' command (see below), normally:
129.57.167.5 clon00 clon00.jlab.org 129.57.167.14 clon10 clon10.jlab.org 129.57.33.22 ccs10 ccs10.jlab.org
3. Execute command domainname CCCHP (or reboot, but not necessary)
4. Execute following:
ypinit -c next host to add: clon00 clon10 ccs10 (for EEL building put it on first place) svcadm enable /network/nis/client ypwhich - shows NIS server (must show first one in the list above) ypcat passwd | grep <username> - shows id/gid etc information
Edit '/etc/nsswitch.conf':
hosts: files dns ('dns' for clon00 and clon10 only ???)
passwd: compat
group: files nis
netgroup: nis
automount: files nis
Fix accounts (can be used to add new account !):
1. /etc/passwd: fix root, add clasrun (for clon00/clon10 add also clasboot, clascron, clasmail), add last 3 lines
2. /etc/shadow: add clasrun, etc, add last line
3. mkdir /root (or 'ln' to file server; normally we have it locally); copy .cshrc file from another machine's /root directory, it must looks like following:
#
# .cshrc for root on clon cluster solaris machines
#
setenv PATH ${PATH}:/opt/SUNWspro/bin
setenv PATH ${PATH}:/opt/sfw/bin
setenv PATH ${PATH}:/usr/sfw/bin
setenv PATH ${PATH}:/usr/ccs/bin
setenv PATH ${PATH}:/usr/sadm/admin/bin
setenv PATH ${PATH}:/usr/local/bin
setenv PATH ${PATH}:/usr/openwin/bin
#
setenv LD_LIBRARY_PATH /opt/SUNWspro/lib
setenv LD_LIBRARY_PATH /opt/sfw/lib:$LD_LIBRARY_PATH
setenv LD_LIBRARY_PATH /usr/sfw/lib:$LD_LIBRARY_PATH
setenv LD_LIBRARY_PATH /usr/local/lib:$LD_LIBRARY_PATH
#
set prompt="%m:%C> "
#
alias ll "ls -al"
#
#temporary!!!
setenv CODA /usr/local/clas/release/current/coda
#
4. Add new groups (onliners etc): /etc/group contails group name, group id and list of group members, while /etc/passwd contains <group id ??? NO !!!>
Set automounts:
1. /etc/auto_master contents:
/- /etc/auto_direct /- auto_direct.ep /u auto.u.ep /w auto.w.ep
2. /etc/auto_direct contents:
# auto_direct (Solaris, clon10-specific) /home -rw,bg clonfs2:/vol/vol0/home /apps -rw,bg clonfs2:/vol/vol0/apps/SunOS_sun4u /usr/local/clas -rw,bg clonfs2:/vol/vol0/local/clas /usr/local/downloads -rw,bg clonfs2:/vol/vol0/local/downloads /usr/local/bin -rw,bg clonfs2:/vol/vol0/local/SunOS_sun4u/bin /usr/local/etc -rw,bg clonfs2:/vol/vol0/local/SunOS_sun4u/etc /usr/local/include -rw,bg clonfs2:/vol/vol0/local/SunOS_sun4u/include /usr/local/lib -rw,bg clonfs2:/vol/vol0/local/SunOS_sun4u/lib /usr/local/man -rw,bg clonfs2:/vol/vol0/local/SunOS_sun4u/man /usr/local/sbin -rw,bg clonfs2:/vol/vol0/local/SunOS_sun4u/sbin /usr/local/share -rw,bg clonfs2:/vol/vol0/local/SunOS_sun4u/share /usr/local/src -rw,bg clonfs2:/vol/vol0/local/SunOS_sun4u/src # # for openssl untill installation from source will works /usr/local/ssl -rw,bg clonfs2:/vol/vol0/local/SunOS_sun4u/ssl # # for diman (see $CLON_PARMS/discr/archive /pretrigger/archive etc) /usr/clas/archives -rw,bg clonfs2:/archives # # work/scratch disks from clon00 /work -rw,bg clon00:/work /scratch -rw,bg clon00:/scratch # # clon00/clon10 specific /mnt/admin/clonfs2 -rw,bg clonfs2:/ /usr/clas/msql_run -rw,bg clonfs2:/msql #
3. Restart automount service:
svcadm restart /system/filesystem/autofs
Reboot machine:
reboot, or 'shutdown -g0 -i6 -y', or 'init 6' (to power down use 'init 5') reboot -- -r (after new hardware installation: '-r' force reconfigure, '-s' force single user mode; 'exit' from single user will continue to multiuser mode)
Install recent patches, SunStudio (without patches !).
Background information
Multiple ethernet ports setting: clon machines can be connected to the several subnets; for example clonxt2:
129.57.167.108 - clonxt2 (iprb0) - goto /etc/hosts 129.57.68.23 - clonxt2-daq1 (e1000g0) - goto /etc/hosts 129.57.69.201 - clonxt2-daq2 (e1000g1) - goto /etc/hosts
To configure do following:
1. Add all interfaces to the /etc/hosts file
2. Create /etc/hostname.e1000g0 file containing clonxt2-daq1, etc for every extra port
3. Edit file /etc/netmasks adding new line for every new port, for example:
129.57.68.0 255.255.255.0
4. Reboot machine, or run commands:
ifconfig e1000g1 plumb ifconfig e1000g1 129.57.68.23 netmask 255.255.255.0 up
To enable/disable services running under svcs just use svcadm enable/disable command. For legacy services rename corresponding script, for example to disable snmp service rename it's startup script:
cd /etc/rc3.d mv S82initsma hide.S82initsma
