Python utils.install missing in the install script when trying to run agent on el6 based distro

[David Nedvěd]

Hi team,

Like the subject suggests python is throwing the following error when trying to run:

./install --username='admin' --password='xxxx' --serverhostname='xxxx.local' --customer='xxxx'

On a EL6 Distro....

Traceback (most recent call last):

  File "./install", line 1464, in <module>

    utils.install(args)

AttributeError: 'NoneType' object has no attribute 'install'

I've tried both the official agent install for el6 x86_64 -- v0.7.2 as well as the agent_utils in the v0.8.0 tag (toppatch/vFenseAgent-nix git repo).

Has anyone else experienced / fixed this issue? - I'm running Python 2.6.8

Cheers,

Hello there David,

can you tell us the full name of the distro you're running?

[David Nedvěd]

I'm running "Amazon Linux 2014.03" on EC2 - which is rebuilt CentOS 6.4/6.5 on Linux 3.x

Linux 3.10.35-43.137.amzn1.x86_64 #1 SMP Wed Apr 2 09:36:59 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

The problem arising from the install script is that we don't officially support that distribution, as we've not tested on it.

***The following does not insure that the agent will work on the distribution.***

What you can do is first open up python and do the following:

>>> import platform

>>> platform.linux_distribution()[0].lower()

and copy what is returned from that last command.

Then open up the install script, and go to line 62 where you will see:

RPM_DISTROS = [

    'fedora',
    'centos',
    'centos linux',
    'redhat',
    'red hat enterprise linux server'
]

and add what you copied from the platform command to this list, like so:

RPM_DISTROS = [
    'fedora',
    'centos',
    'centos linux',
    'redhat',
    'red hat enterprise linux server',
    'what you copied, here'
]

Do not forget the comma after 'red hat enterprise linux server'.

[Humberto Chacon]

Also, slipped my mind, you have to modify rvplugin.py in 'agent/plugins/rv/rvplugin.py'.

After you've done the previous steps open up rvplugin.py and go to line 467 where you will see:

_rpm_distros = ['fedora', 'centos', 'centos linux']

as you guessed, insert what you copied into this list as well like so:

_rpm_distros = ['fedora', 'centos', 'centos linux', 'what was copied']

Thank's Humberto,

Got it installed - I'm now seeing the following in /opt/TopPatch/agent/logs/agent.log

Is this a simple fix?

platform.linux_distribution()[0].lower() returned '' so I've inserted two empty strings in the _rpm_distros & RPM_DISTROS Of each file.

[Humberto Chacon]

Yikes, empty string isn't necessarily the most helpful thing that command could've returned.

Try these three commands and let me know what they return, please:

>>> import platform
>>> platform.dist()
>>> platform.system()
>>> platform.linux_distribution()

After that, could you verify if 'lspci' is installed on that system?

Hello,

I have tried installing the vFense agent in a Centos server with Cloud linux kernel installed. I got these errors but modifying the install script did not fix it. So I edited /etc/redhat-release and changed CloudLinux Server release 6.6 to Centos 6.6, which allowed me to complete the installation.

But the agent is not showing up in the vFense server. The following errors appear in "rvweb_file.log".

~~~
rvweb - ERROR - 404 PUT /rvl/v1/0efdf342-e8bb-4cec-936a-ba3e231f8e83/rv/results/install/apps/os
~~~

Could someone help me?

[Allen Sanabria]

Can you please check rvapi_file.log. Also 

python
>>>from vFense.db.client import *
>>>conn = db_connect()
>>>list(r.table('agents').run(conn))

What does it return?
