Python Annoying error when connecting to target machines

[Anthony Youssef]

Hi,

i am facing an error that is blocking my work on ansible. i am trying to connect from my control machine to a big number of hosts to execute remote commands (around 1000 hosts).

some of these target hosts didn't have python2.6 installed under /usr/bin/python, thus i was not able to connect to them. 

Unix team suggested to put python2.6 under a shared location and thus all machines will be able to connect to it(shared location=./nettools/python_ansible/bin/python), i updated my "group_vars/all" to point to this location, as per below

 ansible_python_interpreter: /nettools/python_ansible/bin/python

now when trying to connect to remote hosts, i faced many issues related to libraries

hp214srv | FAILED! => {
 "changed": false,
 "failed": true,
 "module_stderr": "ld.so.1: python: fatal: libpython2.6.so.1.0: open failed: No such file or directory\n/bin/bash: line 1: 3469 Killed /nettools/python_ansible/bin/python\n",
 "module_stdout": "",
 "msg": "MODULE FAILURE"
}

only machines having python2.6 installed locally were still able to connect since libpython2.6.so.1.0 was found locally (i knew this after running ldd on the python executable)

what i did next, is that i created a wrapper /nettools/python_ansible/bin/python.sh and below is the code inside the wrapper

hp225srv autoengine /usr/local/quality/test/bin/
bash$ vi python.sh
"python.sh" 6 lines, 1088 characters

export PYTHONHOME="/nettools/python_ansible"
echo "ayoussef"
exec /nettools/python/bin/python "$@"

this time where running ansible -m ping dell190srv,dell201srv,dell027srv,hp214srv,hp244srv  from control machine i got the below output

hp244srv | FAILED! => {
 "changed": false,

}

this is really annoying as it is blocking my progress in learning this tool, i am in the middle of the course and i like it.
Please can anyone help me and tell me what is missing, why i am not able to connect to these machines, and what is the best way to do so?
i have been searching for one week for a solution and still no success.
waiting for your help, Thanks in advance!
Regards,
Anthony

It looks like your install of Python isn't complete, or you're missing
some required env.
vars.

Hi,

yeah, but is it possible to execute ansible on remote hosts using python located on a shared location , python should be installed on these remote hosts?

I am asking thia to prevent install python on this big number of machines..
