Upgrade Question

I have inherited a Zenoss install and I'm not sure how to go about upgrading it as I'm not sure if it was installed as a virtual appliance, stack install or native install.  How do I identify which time of install I have?  I can see that it appears to be running CentOS 5.4 (Final).

 

Thanks

    Re: Upgrade Question

    Well, can you go to Advanced -> Versions? So we know what version of Zenoss etc it's running? Then, you probably can do an

    rpm -qa | grep zenoss

    And that should let you know if it's RPM based...

    Yes, I think you'd use the RPMs.

    Anything in the log files? Did zenmigrate complete successfully? Have you tried one more zenoss restart?

    Re: Upgrade Question

    i should mention i've seen this on my ubuntu box before.

     

    two things i made sure of.

     

    mysqld wasn't running and zenoss was stopped.

     

    then i ran the installer again.

     

    started zenoss and mysqld and everything was fine after that.

     

    this still retains your data, although i always to do a zenoss backup before upgrading....

     

    as root

    su zenoos

    zenoss stop

    exit

    /etc/init.d/mysqld stop

     

    ./zenoss-installer ( i guess change this part for the rpm installer)

    let it run it should ask if it needs to launch at the end....say yes

     

    /etc/init.d/mysqld start

     

    should be right.

    Re: Upgrade Question

    weird....

     

    I'm running a centos install as well and i used the bin file off the website to upgrade using my instructions and it worked ok.

     

    as for the problem your having now i'd by checking the daemons page and making sure they are all running.

     

    also check if mysql is running, it it wasn't you would have seen a message about not connecting.

     

    also check out the $ZENHOME/log directory for some logs that may be handy to look through for clues.

     

    sudo su zenoss for the above env variable to work.

     

    if the daemons aren't running sudo su zenoss then zenoss stop (hit that a couple of times) then zenoss start

     

    you've probably already bounced it though.

    Dseagren -

     

    After upgrading you may need to clear your browser cache/cookies.  With javascript changes the browser cache can do some weird things so it's best to clear it after an upgrade.
