SRSS on CentOS 5.11


Installing Sunray Software Server (SRSS) on Centos 5.x

These are the steps I took to get the SunRay software working on Centos. I was able to get this working thanks to scraps of information from Peter Senna Tschudin’s blog In addition to get it working on 32bit like in Peter’s blog, I also got it working on 64 bit. These are the instructions for 64bit.

The SunRays we have are the SunRay 2 model updated with the latest firmware.

Download the software from Oracle’s support portal (requires login)

cd /opt/
# download files from Oracle's website
unzip V37034-01.zip
unzip p16406547_111_Generic.zip

Install the dependencies

yum install glib dhcp openldap-clients tftp-server libXp libXfont.i386 openmotif22 openssl compat-libstdc++-33 libusb-devel compat-openldap kernel-devel gdbm.i386 gcc openmotif.i386 sssd-client.i386

If you are not using sssd you will need to install the nscd.i386 package.

Install the firmware

cd /opt/sros_11.1.1.0/
./utfwinstall

Reboot

Seriously you should reboot

If the services are not running on reboot

You can manually start them with:

/opt/SUNWut/sbin/utadm -L on
/opt/SUNWut/sbin/utstart

SunRay Web Administration

Log into https://mysunrayserver.example.org:8081

With the user: admin and the password you specified in the installer.

Note: Replace port 8081 with the port you selected in the installer if you did not select 8081.

If you can’t log in because the “data store is not responding” proceed to the debugging section.

  • Click “Advanced”
  • Check all the encryption buttons
  • Switch soft to hard for client and server
  • Following instruction to restart client

Debugging

The following two log files were especially helpful in debugging problems.

tail -f /var/opt/SUNWut/log/messages
tail -f /var/log/autholog

Security

We have the SunRays in there own vlan and only the SunRay servers are allowed to communicate with them. You should also firewall the Web Admin ports in my case port 8080 and 8081.

Summary

I havn’t had a lot of luck with a consistent installation using the instructions above. If it doesn’t work the first time try uninstalling and resintalling the SunRay software. Also I was doing this with SELinux disabled and we already had working SunRays with Solaris 10 so I can’t really comment on the dhcp configs or any special network acls we may have in place.

 

Troubleshooting

  1. Make sure the /etc/hosts file reflects the name and IP address of the Sun Ray Server
  2. cd /lib/modules/2.6.18-398.el5
  3. rm build
  4. ln -s ../../../usr/src/kernels/2.6.18-406.el5-x86_64/ build
  5. Add PATH=/opt/SUNWut/sbin:"$PATH" to /root/.bashrc.
