PYTHON INSTALLATION

[tbramha]

Hello Michael,

I have couple of queries. How do I make sure I have installed correctly? I have followed above link.

How to get the ansible version ?
How to validate whether ansble installation is proper or not?

Please provide couple of examples.

Regards,
Brahma.T

[Michael]

To provide instructions - there are a number of things I need to know.

Output of:

# lslpp -L | grep aixtools

# lslpp -Lc bos.mp64

Assuming my packaging of Python3 is installed:

# /opt/bin/pip3 list

Also:

# ls -l /opt/lib

Once I have that, in steps, we can work through the process of installing python and the bdist (binary distribution) packages.

Hello Michael,

Please find the below output . I have installed 32 bit python.

[Michael]

a) to start, you should no longer need aixtools.libffi. That was needed to build cffi on your own, which you will not do now.

# installp -u aixtools.libffi

I'll have more soon.

[Michael]

OK. Finishing up.

b) make sure you have enough space in the filesystem /opt (or /opt/lib)

Code: [Select]

# chfs -a size=+512M /opt
c) You will need to download the wheels CURRENTLY located in http://download/aixtools/test/wheels/5307 as these are the "any" pure Python wheels AND the AIX 32-bit wheels. Their current tagging shows they were built on AIX 5.3 TL7.

d) read through the following - PAY SPECIAL ATTENTION - to the mv commands that chenge the tag of the AIX binary wheels.

e) after the command "pip install *.whl" finishes you should have a working ansible. I do not know ansible, so the only test I can suggest is:
# which ansible ## (should be /opt/bin/ansible, you can create a symbolic from /usr/bin if you need it)

# ansible --version ## or /opt/bin/ansible --version

e.g.:

Code: [Select]

root@x062:[/home/root]which ansible
/opt/bin/ansible
root@x062:[/home/root]ansible --version
ansible 2.9.1
  config file = None
  configured module search path = ['/home/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']

  executable location = /opt/bin/ansible

Hope this helps!

Hello Michael,

Thanks for your reply. Do you want me to run  installp -u aixtools.libffi now ?

Could you please help me with below queries

1. Under troubleshooting Based on the output from pip3 in debug we will run below command right?


root@x066:[/data/prj/python/wheels/AIX-5307]ln  MarkupSafe-1.1.1-cp36-cp36m-AIX_5307_0747_64.whl MarkupSafe-1.1.1-cp36-cp36m-AIX_6106_1043_64.whl

2. I have executed below and ended got below errors. Could you please tell me was it successful installation or not?

(ansible) root@ztapp08:/home/exttbra # ln MarkupSafe-1.1.1-cp36-cp36m-AIX_5307_0747_32 MarkupSafe-1.1.1-cp36-cp36m-AIX_6106_1043_64.whl
ln: MarkupSafe-1.1.1-cp36-cp36m-AIX_5307_0747_32: No such file or directory

ansible) root@ztapp08:/home/exttbra # pip install Mark*6106*whl
ERROR: MarkupSafe-1.1.1-cp36-cp36m-AIX_6106_1043_64.whl is not a supported wheel on this platform.

3. You mentioned  under point 7 " Later, when you are satisfied as root, go back and install the wheels into the "SYSTEM" python libraries" .  Could you please explain it in detail

4. If I have to install 64bit python 3.6 then I should get wheels from http://download.aixtools.net/test/wheels/6106/ right?


Thanks in advance for bearing many queries from me. I have followed http://www.rootvg.net/content/view/847/169/ and waiting for my development team to test their code.

Regards,
Brahma.T

Since you installed the 32-bit version, you need the wheels from the 5307 directory.

Please read - carefully - in my previous post - the section labeled:

d) read through the following - PAY SPECIAL ATTENTION - to the mv commands that change the tag of the AIX binary wheels.

If you have any additional issues - please provide the output of

Code: [Select]

pip debug

[Michael]

Sounded like you were almost there. Would like to hear how things are progressing!

Hello Michael,

Had a moment - and have the wheel in http://download.aixtools.net/test/wheels/5307

You will need to link/move to a new name in order to load - same as the other wheels.
