Upgrading to Zenoss 4.2.4

I found the instructions for performing an upgrade to 4.2.4 were rather diffuse.

There are some comments on the wiki page here - Install Zenoss

The main instructions are in the installation guide which you can get which is referenced on the above page - Zenoss Core 4 Installation Guide

These instructions say you need to install the new utility called ZenUp (which I believe is still beta code at August 9th 2013). It references the Zenoss Service Dynamics ZenUp Installation and Administration manual (and this is not a hyperlink) and obviously is less than appropriate for Core users; however, there is a good ZenUp reference here on the wiki at ZenUp.

I started from a community script installation of Zenoss 4.2.3 on CentOs 6.3. Start from Chapter 5 of the installation Guide. These are my comments / updates on those instructions.

  • You should definitely have taken a Zenoss backup before you get to upgrading but..... there is a bug with 4.2.3 that prevents zenbackup from running cleanly. The fix (as the zenoss user) is:
    • mysql -u root
    • GRANT SELECT ON mysql.proc to zenoss;
  • additional notes to the ZenUp wiki item:
    • Installing ZenUp creates a zenup user with a home directory of /home/zenup
    • The zenup utility is installed under /opt/zenup/ under the bin directory so any zenup command run as the zenoss user needs to be:
      • /opt/zenup/bin/zenup <parameter>
  • rpm commands all have the --nodeps parameter which I feel is dangerous. Omitting this shows what will be broken. In my case, it was only the installed Zenoss so went ahead with the --nodeps override
    • Note that I had postfix installed which ended up broken but before the second upgrade I did, I found that postfix was already broken before starting!
  • On checking for installed java, I had jre-1.6.0_31-fcs.x86_64 (which I assume is not correct?? so I removed it)
  • Accessing both the Java code and MySQL requires an Oracle login id
