yum install python-setuptools to install easy_install and ansible - errors: AttributeError: other Python Errors

Goal: Install ansible on a RedHat Linux machine.

Little overview on how it all started:
When my Linux machine was RedHat 5.9 (Tikanga), the default python installed version was 2.4. I tried my best, but couldn't get anything to work as Ansible requires python >= 2.6. I tried installing 2.7.9 on Linux 5.9 version but then things started to act up really fast.

I did try 2.7.9 python on Linux 5.9 as "make altinstall" instead of install but still there were lots of errors while running yum / etc system level commands.

Few errors which came there were (with or without running sudo):

# sudo pip install ansible

etc....

Finally to my luck, I thought, let's try installing python again from scratch (so I ran yum erase python, !!! beware !!!!) and to my knowledge, it was the best command I ever ran in my experience with a little oversight. End result: I ended up creating a new product, here: http://www.keepcalmandcarryon.com/creator/?shortcode=qCsMlpyc

Anyways, ... Now, I got the server revived with a newer version of RedHat (version 6.6 Santiago) and this time default Python on it was: 2.6.6.





Current situation: THIS is now, what I'm facing now on RH Linux 5.9 with Python 2.6.6 installed.

I'm running: sudo easy_install pip but I got an error:

sudo: easy_install: command not found


To resolve the above, I'm now running:
sudo yum install python-setuptools

It found it... but showing me some an error.

Any idea, how can i get easy_install, pip or ansible on my Linux machine 6.6 (now).

Thanks.

Answer

Ran the following commands to fix everything and now ansible is finally installed:

wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
sudo rpm -ivh epel-release-6-8.noarch.rpm

But at this stage, I got an error for Jinja2 ... as below: ImportError: No module named setuptools

-bash-4.1$ sudo python setup.py install
Traceback (most recent call last):
  File "setup.py", line 40, in <module>
    from setuptools import setup, Extension, Feature
ImportError: No module named setuptools
-bash-4.1$

To fix the above and proceed, I ran the following commands to get python-setuptools (which installs easy_install)

wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python

Great, now I have easy_install installed on my machine.

-bash-4.1$ which easy_install
/usr/bin/easy_install
-bash-4.1$

At this point, I wanted to install ANSIBLE, so I ran the following:

sudo easy_install pip
sudo pip install ansible

The last line in the above ansible install command's output was:

Successfully installed ansible-1.9.0.1 jinja2-2.7.3 markupsafe-0.23 pycrypto-2.6.1

Now, I can see ansible on my machine.

-bash-4.1$ which ansible
/usr/bin/ansible
-bash-4.1$

Oh, oh... something is still not good:

-bash-4.1$ ansible --help

Traceback (most recent call last):
  File "/usr/bin/ansible", line 36, in <module>
    from ansible.runner import Runner

    if _fastmath is not None and not _fastmath.HAVE_DECL_MPZ_POWM_SEC:
AttributeError: 'module' object has no attribute 'HAVE_DECL_MPZ_POWM_SEC'

-bash-4.1$

I checked, my LD_LIBRARY_PATH variable was already set/exported as:

LD_LIBRARY_PATH=/usr/lib64/:/usr/local/lib64

Then what else... OK.

Ran the following steps/commands to resolve the above error and get ansible to actually WORK!!!. For prompts, I said Yes "y".


echo "y" | sudo pip uninstall pycrypto
echo "y" | sudo yum erase python-crypto
echo "y" | sudo pip uninstall ansible
sudo pip install ansible
## Time to get gmplib 6.0.0(a) etc
wget https://gmplib.org/download/gmp/gmp-6.0.0a.tar.bz2
tar -xvjpf gmp-6.0.0a.tar.bz2
## Change to the above extracted folder and run some commands, seems like they'll run forever.
cd gmp-6.0.0
./configure
sudo make  || echo "these few steps will take good amt of time to complete"
sudo make check || echo "hang on and see if all tests passes in the check process"
sudo make install || echo "final shenzi will be done shortly"
sudo make check || echo "really!!!! ????"
which ansible
ansible || ansible --help

PS: Stay away if you can from "yum erase python" and entering "y" for it, good luck.
