Hi

I've just completed a fresh install of Zenoss Core 4.2 on a fresh install of CentOS6.3.

However, the install will not initialise and I get this:

=
Install       1 Package(s)

Total size: 311 M

Downloading Packages:

Zenoss not initialized.  Performing first-boot initialization...
Fresh install pre steps
Please confirm that the JRE in the PATH is Oracle's version.

When I enter:

java -version I get this:
-bash: Java Command not found.

However, by entering export PATH=$PATH:/usr/java/jre1.6.0_31/bin/ it allows me to view the java version

Then I entered

java -version which then got me:
java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b04)
Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode)

But Zenoss still wont start. as a bit of linux newb, I'm kind of struggling here

Any help is greatly appreciated

Cheers


Mike

Hi Mike,

The installation procedure for Oracle Java JRE as given in the official Zenoss core installation manual is not very clear (especially for beginners) so I'll post here how I did it on my servers (you must be root or you're looking for trouble here) :

*#Make sure you're in the home directory, download and extract Oracle JRE*
cd ~
wget -O jre-6u33-linux-x64-rpm.bin http://javadl.sun.com/webapps/download/AutoDL?BundleId=65509 http://javadl.sun.com/webapps/download/AutoDL?BundleId=65509
chmod -v +x jre-6u33-linux-x64-rpm.bin
sh ./jre-6u33-linux-x64-rpm.bin
*#Now put it to the right place and tell the system to use it*
mkdir -pv /usr/java
mv -v jre1.6.0_33 /usr/java
alternatives --config java   *#make note of the highest sequence number here in case you have other Java package because they can coexist safely*
alternatives --install /usr/bin/java java /usr/java/jre1.6.0_33/bin/java 1   *#use next available sequence number to designate the preferred Java, in my case it is 1 which means Oracle JRE is the only one*
alternatives --config java     *#optional, just to make sure Oracle JRE is the preferred one*
java -version
cd /usr/java
ln -sv /usr/java/jre1.6.0_33 default
*#Modify /etc/profile to include the following line*
export JAVA_HOME=/usr/java/default

Of course, you must adapt this to your needs.
