[edit] Zenoss Core 4.2.4

Zenoss Core 4.2.4, our latest stable version, is now available! Installation instructions and download links can be found below.

For some comments on upgrading from Zenoss 4.2.3 to 4.2.4 try the document here Upgrade tips from Jane Curry. Note particularly that removing all non-Zenoss ZenPacks may be more destructive than upgrading with them - see the notes.

[edit] Supported Operating Systems

Zenoss Core 4.2.4 runs natively on the following Linux-based operating systems:

  • Red-hat.png Red Hat Enterprise Linux 64-bit 6.x (recommended) or 5.x
  • Centos logo.png CentOS 64-bit 6.x (recommended) or 5.x

[edit] HOWTO, Filing Bugs

Unofficial support for Debian and Ubuntu can be found on Hydruid's blog. For help please ask in #zenoss on irc.freenode.net, or in the forums. These scripts are not supported by Zenoss. To report bugs, or submit fixes please submit them on the Github project.

[edit] Manual Installation

The traditional way to install Zenoss is to follow our Zenoss Core 4 Installation Guide. The Installation Guide will guide you through the process of installing Zenoss Core 4.2 on a 64-bit version of Red Hat Enterprise Linux 5.x or 6.x, using RPMs that you download from SourceForge:

Download RPMs for Installation, from SourceForge:

Please see the Zenoss Core 4 Release Notes for relevant information related to manual installation.

[edit] auto-deploy Installation

Bulbgraph.png Note: Updated for 4.2.4
The simplest way to install Zenoss Core 4.2 on a newly-deployed RHEL/CentOS 64-bit 5/6 system is to use our auto-deploy script, which downloads all required files for you. To use the script, first set up a new server running one of our supported operating systems. Then, as root, run the following commands: 

# wget --no-check-certificate https://github.com/zenoss/core-autodeploy/tarball/4.2.4 -O auto.tar.gz
# tar xvf auto.tar.gz
# cd zenoss-core-autodeploy-*

Now, you have the option of editing zenpack_actions.txt, which defines all ZenPacks that will be installed by default (all Core ZenPacks). If you would like to avoid installing certain ZenPacks, then remove the corresponding lines from this file and save it.

Now you are ready to install Zenoss Core 4.2.4: 

# ./core-autodeploy.sh

As part of the install process, your Zenoss installation will be secured, and you will be asked if you would like to set a secure root password for MySQL. It is strongly recommended that you do so.

The auto-deploy script will automatically download and install all required dependencies, as well as Zenoss Core 4.2. After the script completes successfully, use your favorite Web browser and head to port 8080 of your new server (for example, http://127.0.0.1:8080), and then set the Zenoss administrator password and create your initial user account using the Web interface.

Next, you'll want to Add a Device to Zenoss.

If you encounter issues with the auto-deploy script, please report them on the Discussion page.

[edit] Fix for upgrade to 4.2.4

If you used the 4.2.3 community script to install, it uses a security script to ensure passwords are changed from the default values. This can cause a problem when upgrading as you may find that the 4.2.4 RPM copies over the secure passwords set by the security script in some files. To fix this, simply copy the secure password to global.conf, and elsewhere as needed.

A list of the files/variables where this password is used is provided below: 

global.conf:zodb-password
global.conf:amqppassword
global.conf:zep-password
global.conf:hubpassword
zenjmx.conf:#  zenoss., default: 
zenjmx.conf:#hubpassword
zenwinperf.conf:#  zenoss., default:
zenwinperf.conf:#hubpassword
zodb_db_main.conf:    passwd
zodb_db_session.conf:    passwd

[edit] Fix for Sticking JDBC Connections in 4.2 SP1

Getting these error messages?

org.springframework.transaction.TransactionSystemException: Could not roll back JDBC transaction; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: No operations allowed after connection closed.Connection was implicitly closed by the driver.

Run the following as the zenoss user, or upgrade to 4.2.4: 

$ zeneventserver-config -u zep.jdbc.pool.test_on_borrow=true
$ zeneventserver restart
