Nagios XI installation error - python

[BenShirley]

I am attempting to install the demo version of Nagios XI version 2014 r1.2 on a clean install of CentOS 6.5. The installation fails at the following:

--> Processing Dependency: python(abi) = 2.4 for package: python-numpy-1.0.1-1.el5.rf.x86_64

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
RESULT=1

Help?

Was this a clean *minimal* install? It looks like you already have a later version of Python installed which is typical in Desktop installs and full server installs.

Thanks for the response. I went ahead and reinstalled CentOS 6.5 with ONLY the base packages, as you suggested. That definitely helped--I got further along on the install.

However, now it errors out at a different step:

Running './3-dbservers'...
PostgresQL installed OK - continuing...
Initializing PostgresQL...
Starting PostgresQL...
Starting postgresql service: [FAILED]
ERROR: Could not start PostgresQL - exiting.
RESULT=1

Any suggestions? (I've attached a new install.log)

Thanks in advance.

Did you install using the Minimal ISO image or did you choose the Basic Server install?

You need to choose minimal otherwise a lot of those packages will already be installed.

Aha! I guess I was thrown off by the message you get when you start the install:

IMPORTANT: This script should only be used on a 'clean' install of CentOS or RedHat. Do NOT use this on a system that has been tasked
with other purposes or has an existing install of Nagios Core. To create such a clean install you should have selected ONLY the
'Base' package in the OS installer.

I had been trying to install CentOS using Kickstart, editing the packages installed in the script. I first tried including only the @base package group, but then after you pointed out that was wrong, I tried including only the @core group. Both had the same results as my last post.

Finally, I burned a DVD and installed from that, selecting the Minimal install option, and that worked.

Thanks!

I can understand how that message might be a bit confusing. I'll see if we can get that changed. At any rate, glad it is working now and I will be closing this thread.
