Revision as of 02:08, 7 May 2009

To add users

useradd -u <uid> -g<gid>

so that uid and gid match the existing ones

rocks sync users 
cluster-fork '/sbin/service autofs restart'

to replicate the login info immediately, otherwise they get sent out once an hour This copies their password/login info and autofs entries into /etc/auto.home for the compute nodes. DO NOT EDIT /etc/auto.home

Allow access to wordpress and ganglia from everywhere via https

cd /etc/sysconfig/
chmod u+w iptables
emacs iptables

add line

-A INPUT -m state --state NEW -p tcp --dport https -j ACCEPT

Hash known hosts, so a hacked account on one system won't propagate to others so easily

cd /etc/ssh/
chmod u+w ssh_config 
emacs ssh_config

add line under Host* HashKnownHosts yes

Share the /cworkspace among all the cluster nodes

This actually shares the dirs through the NFS

chmod u+w exports 
emacs exports 
/ws/ifp-32-1 10.0.1.0/255.255.255.0(rw)
/ws/ifp-32-2 10.0.1.0/255.255.255.0(rw)
/etc/rc.d/init.d/nfs restart

You have to do the analogous thing on the compute nodes, if you want to share their something from them.

This sets up the automounts on the /cworkspace

cd /etc/
chmod u+w auto.*
emacs auto.master

add line

/cworkspace /etc/auto.share --timeout=1200

emacs auto.share

add lines

cluster-fork '/sbin/service autofs restart'

To change scheduling to equal cpu allocation among waiting users

qconf -mconf

add lines

enforce_user auto
auto_user_fshare 100

qconf -msconf

add lines

weight_tickets_functional 10000

To make qstat show jobs of all users

cd /opt/gridengine/default/common
emacs sge_qstat

add line

-u * 

get a latish subversion from rpmforge (the one from centos is too old):

wget http://packages.sw.be/subversion/subversion-1.5.6-0.2.el5.rf.x86_64.rpm
rpm -ivh subversion-1.5.6-0.2.el5.rf.x86_64.rpm

get a latish version of python

this will install /usr/bin/python2.6 but won't touch the /usr/bin/python that was there originally

wget http://www.python.org/ftp/python/2.6.2/Python-2.6.2.tar.bz2
tar -xjvf Python-2.6.2.tar.bz2 
cd Python-2.6.2
./configure 
yum install readline-devel
make -j 4
make altinstall
