Installing Sunray II server software on Centos 5.3

I spent many weeks trying to install Sunray server software on Linux.

I was NOT able to make it work with Centos 5.3 x86_64. Maybe this is related somehow to GDM package but it did not work.

It worked when using i386 version of Centos.

See the step by step guide.

1 - Install Centos 5.3 i386
1.1 - If you have more than 3GB of installed RAM, run as root: yum -y install kernel-PAE

2 - Run as root:
yum -y update
reboot

3 - Download:
srss_4.1_linux.zip from http://www.sun.com/software/sunray/getit.jsp
jre-6u13-linux-i586-rpm.bin from http://www.java.com
apache-tomcat-5.5.27.tar.gz from http://tomcat.apache.org/

4 - run as root:
yum install glib dhcp openldap-clients openldap tftp-server libXp openmotif22 openssl compat-libstdc++-33 libusb-devel compat-openldap
yum groupinstall "Development Tools"
yum install kernel-devel

5 - run as root:
cd /usr/lib
ln -sf libldap-2.3.so.0.2.31 libldap.so.199
ln -sf libgdbm.so.2.0.0 libgdbm.so.3
ln -sf liblber-2.3.so.0.2.31 liblber.so.199

6 - install jre that you have downloaded. Run as root:
sh jre-6u13-linux-i586-rpm.bin

7 - install tomcat that you have downloaded. Run as root:
cd /opt
tar xvzf apache-tomcat-5.5.27.tar.gz
ln -sf apache-tomcat-5.5.27 apache-tomcat

8 - Add tomcat as a service. copy and past above code to /etc/init.d/tomcat

#!/bin/sh
#
# Tomcat Server
#
# chkconfig: 345 96 30
# description: Java servlet container

JAVA_HOME=/usr/java/latest/

PATH=${JAVA_HOME}/bin:${PATH}

TOMCAT_START=/opt/apache-tomcat/bin/startup.sh

TOMCAT_STOP=/opt/apache-tomcat/bin/shutdown.sh

export JAVA_HOME PATH

start()
{
if [ -x ${TOMCAT_START} ]; then
echo "Starting tomcat server..."
${TOMCAT_START} &
else
echo "Cannot start tomcat server"
fi
}

stop()
{
if [ -x ${TOMCAT_STOP} ]; then
echo "Stopping tomcat server..."
${TOMCAT_STOP} &
else
echo "Cannot stop tomcat server"
fi
}

restart()
{
stop
sleep 10
start
}

status()
{
echo "No status available for tomcat server"
}

case "$1" in
'start')
start
;;
'stop')
stop
;;
'restart')
restart
;;
'status')
status
;;
*)
echo "Please supply an argument [start|stop|restart]"
esac

9 - To complete tomcat installation, do not forget to:
chmod +x /etc/init.d/tomcat
chkconfig tomcat on
service tomcat start

10 - Unzip the Sunray Server Software that you have downloaded:
unzip srss_4.1_linux.zip
cd srss_4.1
./utinstall
reboot

11 - First Sunray Server Software configuration step:
cd /opt/SUNWut/sbin
./utconfig
reboot

12 - Second Sunray Server Software configuration step:
This is the only dificult step. The utadm uses a logic that I haven't understood about /etc/hosts. The only way to make it works on my scenario is to edit /etc/hosts before running utadm.

The trick is to add an entry to /etc/hosts that contain the real ip address of your server and to comment the 127.0.0.1 entry. See the example above:

Before editing:
vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost #Comment this line
::1 localhost6.localdomain6 localhost6

After editing:
# Do not remove the following line, or various programs
# that require network functionality will fail.
#127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
10.0.0.115 localhost localhost.localdomain

Now just run as root:

cd /opt/SUNWut/sbin
./utadm -a eth0

And undo the changes YOU MADE on /etc/hosts. Do not remove the line added by utadm. See how it should look like after you undo your changes:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
#10.0.0.115 localhost localhost.localdomain
192.168.128.1 localhost-eth0.localdomain # SUNRAY ADD - DO NOT MODIFY

Now run as root: reboot

And enjoy it.
