How to Fix “Shared connection to x.x.xx closed” Ansible Error

Must read

In this short article, we will explain how to solve the: “module_stderr“: “Shared connection to x.x.x.x closed.rn”, “module_stdout”: “/bin/sh: /usr/bin/python: No such file or directoryrn”, while running Ansible commands.

The following screenshot shows the Ansible module error. We encountered this error while running an Ansible command to execute commands on two newly deployed CentOS 8 servers.

Ansible Module Error

From the error details, the connection failed because the shell(s) in the remote system couldn’t find the Python interpreter (/usr/bin/python) as indicated by the line: “module_stdout”: “/bin/sh: /usr/bin/python: No such file or directoryrn“.

After checking the remote hosts, we discovered that the systems don’t have Python 2 installed.

They have Python 3 installed by default and its binary is /usr/bin/python3.

According to the Ansible documentation, Ansible (2.5 and above) works with Python version 3 and above only. Also, Ansible is supposed to automatically detect and use Python 3 on many platforms that ship with it.

However, if it fails to, then you can explicitly configure a Python 3 interpreter by setting the ansible_python_interpreter inventory variable at a group or host level to the location of a Python 3 interpreter as described below.

Passing Python Interpreter to Ansible on the Command-line

To fix the above error temporarily, you can use the -e flag to pass the Python 3 interpreter to Ansible as shown.

$ ansible prod_servers  -e 'ansible_python_interpreter=/usr/bin/python3' -a "systemctl status firewalld" -u root
Set Python Interpreter via Command-line
Set Python Interpreter via Command-line

Setting Python Interpreter for Ansible in the Inventory

To fix the error permanently, set the ansible_python_interpreter inventory variable in your inventory /etc/ansible/hosts. You can open it for editing using the v/im or nano text editor as shown.

$ sudo vim /etc/ansible/hosts
OR
# vim /etc/ansible/hosts

Append the following line to each host or hosts in a group:

ansible_python_interpreter=/usr/bin/python3

So, your hosts’ definitions can look like this:

[prod_servers]
192.168.10.1			ansible_python_interpreter=/usr/bin/python3
192.168.10.20			ansible_python_interpreter=/usr/bin/python3.6
Set Python Interpreter for Ansible
Set Python Interpreter for Ansible

Alternatively, set the same Python interpreter for a group of hosts as shown.

[prod_servers]
192.168.10.1		
192.168.10.20		

[prod_servers:vars]
ansible_python_interpreter=/usr/bin/python3
Set Python Interpreter-for All Hosts in a Group
Set Python Interpreter-for All Hosts in a Group

Setting Default Python Interpreter in Ansible Configuration

To set the default Python interpreter, you can set the ansible_python_interpreter inventory variable in Ansible’s main configuration file /etc/ansible/ansible.cfg.

$ sudo vim /etc/ansible/ansible.cfg

Add the following line under the the [defaults] section.

ansible_python_interpreter=/usr/bin/python3
Set Python Interpreter in Ansible Configuration
Set Python Interpreter in Ansible Configuration

Save the file and close it.

Now try to run the Ansible command once more:

$ ansible prod_servers -a "systemctl status firewalld" -u root
Check Ansible Command
Check Ansible Command
