If you get the following error:
“msg”: “Failed to validate the SSL certificate for rpm.nodesource.com:443. Make sure your managed systems have a valid CA certificate installed. If the website serving the url uses SNI you need python >= 2.7.9 on your managed machine (the python executable used (/usr/bin/python) is version: 2.6.6 (r266:84292, Aug 18 2016, 15:13:37) [GCC 4.4.7 20120313 (Red Hat 4.4.7-17)]) or you can install the `urllib3`, `pyOpenSSL`, `ndg-httpsclient`, and `pyasn1` python modules to perform SNI verification in python >= 2.6. You can use validate_certs=False if you do not need to confirm the servers identity but this is unsafe and not recommended. Paths checked for this platform: /etc/ssl/certs, /etc/pki/ca-trust/extracted/pem, /etc/pki/tls/certs, /usr/share/ca-certificates/cacert.org, /etc/ansible. The exception msg was: [Errno 1] _ssl.c:492: error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure.”
It is because the managed node does not have python >= 2.7.10 you can resolve it by executing:
sudo yum install pyOpenSSL -y
sudo pip install urllib3 ndg-httpsclient pyasn1
