Well, it is the first time to running a RHEL 5 for me, at same time got zenoss built successfully on it. zenoss-2.1.2 was build from source, the whole process went a while since RHEL is in one of my VMware session; CPU %sy was pretty high during building source code.
The INSTALL.txt file is good enough, my installation how-to can be really sample:
- Read INSTALL.txt
- add zenoss user
- start mysql
- upload zenoss tarball to zenoss home directory
- login as zenoss
- untar zenoss tarball then run the following, good luck!
bash$ $ZENHOME/bin/zenoss startbash$ $ZENHOME/bin/zenoss status
- Then I access to Zenoss portal, got this error.
HTTP Status 404 - /zport/dmd
I reboot the RHEL server, then start mysql and zenoss. Finally, everything goes smoothly. Let’s take this nice zenoss portal. On my RHEL, mysql, snmp and python were installed with OS; other packages might installed from zenoss source tarball. I am not sure about this, you could check above to see my install log.Install tips:
- Package dependence should be consider before you build Zenoss source code. A full RHEL install is a lazy idea to solve this problem; but it is still the best practice if you are new to both Linux and Zenoss.
- Start zenoss daemons might take one minute or more. If you access to zenoss portal immediately, you could get a HTTP Status 404 error. Before you see balance stone, please be patience.
Auto-Discovery of Devices
It’s time to read ZenossAdminGuide211.pdf; BTW that’s a good document. I will go ahead to note down what I did in my testing evn. Please turn to P47, I will go from there. For sure you have something discovered, please read the following tips:
- The Zenoss machine should have snmp installed, including the following packages:
As far as I know net-snmp-utils-5.3.1-19.el5 is a necessary. Without this package, you do not have ability to snmpwalk any device via SNMP protocol; in other word you can not get enough information about that remote device.
- Add a right network ID, here is a example:
- snmpwalk at least one snmp-enable device, here is a example:
- Because my RHEL installation is big enough, I don’t know what are dependence packages for Zenoss; no time to list all of them. Does have this list?
- I’ve no idea how to configure snmpd on Solaris. What I did was just modified /etc/snmp/conf/snmpd.conf
- How to restart snmp daemon for Solaris?
- Do you have any good blog about zenoss? I will write a Chinese blog after this one to conclusion zenoss installation. Please give a hint if you have any comment.
