Detailed instructions

Base root-level installation

# Node came pre-installed with the osg-ca-certs
# If not, follow the instructions at
# https://twiki.grid.iu.edu/bin/view/Documentation/Release3/InstallOSGClient#Install_the_CA_Certificates_A_qu

# Basic OSG client installation
# Note: Not essential, but I like to have it in advance
yum install osg-client

# Install basic condor, make sure it is client only
yum install condor
echo -e "#Disable daemons, this is client only\nDAEMON_LIST=NONE" >/etc/condor/config.d/99_client_only.config

# Make sure m2crypto and python-rrdtool are installed
yum install m2crypto python-rrdtool

# Make sure httpd is installed
yum install httpd
# hide the directory structure
touch /var/www/html/index.html

#now create the needed user
useradd frontend

# give it a copy of the host cert
# not the most elsegant solution, but it works
mkdir ~frontend/.globus
cp /etc/grid-security/host*pem ~frontend/.globus/
chown -R frontend:frontend ~frontend/.globus

# And do whatever needed to be able to log in

# Create frontend web dir
mkdir /var/www/html/vofrontend
chown frontend:frontend /var/www/html/vofrontend

# start httpd
service httpd start
chkconfig httpd on
