Manual and Offline Installations
Instead of using the installer script as described in the Quickstart, you can manually install the CLI and its dependencies. Before proceeding, be sure you meet the Requirements.
You can also download the CLI installation files and perform an offline installation.
Step 1: Installing Python
Python installation instructions vary for each operating system that the CLI supports.
Note
The CLI supports only the Python versions listed in the CLI Requirements.
Install a supported version of PythonВ from the Python Windows downloads page. During installation, choose to add Python to the PATH and/or environment variables (depending on the prompt).
Some versions of Oracle Linux come with incompatible versions of Python, and might require additional components to install the CLI. Before installing the CLI, run the following commands on a new Oracle Linux image.
Tip
Oracle Autonomous Linux 7 and Oracle Linux Cloud Developer 8 come with the CLI pre-installed.
Oracle Linux 7 and Oracle Linux 8
Oracle Linux 6
Before you install the CLI, run the following commands on a new CentOS image.
CentOS 7, CentOS 8
Before you install the CLI, run the following commands on a new Ubuntu image.
Ubuntu 16, Ubuntu 18, and Ubuntu 20
Mac OS X comes with Python pre-installed.
To install the latest version of Python on Mac OS X, see the official Python documentation.
Step 2: Creating and Configuring a Virtual Environment
The venv Python module is a virtual environment builder that lets you create isolated Python environments. We recommend installing the CLI in a virtual environment.
Installing and Activating your Virtual Environment
After Python is installed, set up a virtual environment for your operating system using the following steps.
Navigate to the directory in which you would like to create the virtual environment.
Create the virtual environment by running the following command:
Navigate to the directory in which you would like to create the virtual environment.
Create the virtual environment by running one of the following commands, depending on the version of Python installed:
Step 3: Installing the Command Line Interface
You can download the CLI from GitHub or install the package from Python Package Index (PyPI).
To install using the GitHub download:
Download and unzip oci-cli.zip.
Run the following command.
To install using PyPI, run the following command:
For information on how to start a CLI session, see Using the CLI.
Installing Without a Virtual Environment
We do not recommend installing the CLI in your system-wide Python and suggest that instead you install the CLI using the installer or virtual environment.
In cases where you are trying to install the CLI in your system-wide Python using the latest pip version, you might encounter conflicts with some distutils installed packages. Following is an example error message when this occurs:
Another option is to install the CLI for the user using the following command, although this approach is not supported:
Offline Installation
If you have Python 3 installed, you can perform an offline installation of the OCI CLI.
For troubleshooting offline installs, see Common Issues or create an issue on GitHub.

How to see the version of Oracle Linux
Determine Oracle Linux version
Oracle Linux is based on Red Hat Enterprise Linux. At first, it may be confusing to determine what specific operating system is running. This is because both have the /etc/redhat-release file.
If that file exists, use the cat command to display the contents. Next step is to determine if there is a /etc/oracle-release file as well. If so, then you can be sure that Oracle Linux is running.
Sample output might be: Oracle Linux Server release 6.7
Other options
Next time when you are on a system and not sure what it is running, use this:
This shows you any files that might give a hint on the operating system version.
