Quickstart

Installing the CLI

Oracle Linux 8

If you’re using Oracle Linux 8, you can use dnf to install the CLI.

Note

We strongly recommend running sudo dnf update regularly to ensure your system is up-to-date by installing available updated RPMs.

To use dnf to install the CLI:

The CLI will be installed to the Python site packages:

Documentation and examples will be installed in the /usr/share/doc/python36-oci-cli- / directory.

To uninstall the CLI:

Oracle Linux 7

If you’re using Oracle Linux 7, you can use yum to install the CLI.

To use yum to install the CLI:

The CLI will be installed to the Python site packages:

Documentation and examples will be installed in the /usr/share/doc/python36-oci-cli- / directory.

To uninstall the CLI:

Mac OS X

You can use Homebrew to install, upgrade, and uninstall the CLI on Mac OS.

To install the CLI on Mac OS X with Homebrew:

To upgrade your CLI install on Mac OS X using Homebrew:

To uninstall the CLI on Mac OS X using Homebrew:

Windows

Open the PowerShell console using the Run as Administrator option.

The installer enables auto-complete by installing and running a script. To allow this script to run, you must enable the RemoteSigned execution policy.

To configure the remote execution policy for PowerShell, run the following command.

Linux and Unix

Note

The installer script automatically installs the CLI and its dependencies, Python and virtualenv. Before running the installer, be sure you meet the requirements.

Note

Oracle Linux 8 and Oracle Linux Cloud Developer 7 have the CLI pre-installed.

1. Open a terminal.
2. To run the installer script, run the following command:

Note

To run a ‘silent’ install that accepts all default values with no prompts, use the —accept-all-defaults parameter.

Verifying the OCI CLI Installation

1. From a command prompt, run the following command:

Installation Script Prompts

The installation script prompts you for the following information.

• If you do not have a compatible version of Python installed:
  • Windows and Linux: You are prompted to provide a location for installing the binaries and executables. The script will install Python for you.
  • MacOS: You are notified that your version of Python is incompatible. You must upgrade before you can proceed with the installation. The script will not install Python for you.
• When prompted to upgrade the CLI to the newest version, respond with Y to overwrite an existing installation.
• When prompted to update your PATH, respond with Y to be able to invoke the CLI without providing the full path to the executable. This will add oci.exe to your PATH.

Setting up the Config File

Before using the CLI, you must create a config file that contains the required credentials for working with Oracle Cloud Infrastructure . You can create this file using a setup dialog or manually using a text editor.

Use the Setup Dialog

To have the CLI walk you through the first-time setup process, use the oci setup config command. The command prompts you for the information required for the config file and the API public/private keys. The setup dialog generates an API key pair and creates the config file.

For more information about how to find the required information, see:

Manual Setup

If you want to set up the API public/private keys yourself and write your own config file, see SDK and Tool Configuration.

Tip

Use the oci setup keys command to generate a key pair to include in the config file.

Oracle linux console install

This tutorial shows you how to install and set up the Cockpit web console on an Oracle Linux 8 system to enable you to perform basic system configuration and administration by using a web-based user interface.

Background

Oracle Linux 8 includes a web console you can use for system administration. The web console is called Cockpit. For non-minimal installations, Cockpit is automatically installed, although not automatically enabled. Cockpit provides a web browser interface for performing system configuration and administration tasks, either locally or remotely on multiple servers. These tasks include system resource monitoring and log review, network and firewall configuration, and package management and updates. Cockpit uses the same APIs to access system services, so any changes you make using operating system command line tools are updated in real time in Cockpit.

Note that Cockpit is also available for Oracle Linux 7, but the instructions provided here are aimed at Oracle Linux 8 users.

What Do You Need?

• A system with Oracle Linux 8 installed

Install the cockpit package

On Oracle 8 systems with non-minimal installations, the cockpit package is included by default. Otherwise, you would need to manually install Cockpit. In either case, running the following command ensures that the package is installed and is up to date.

Enable and start the Cockpit service

To enable and start the Cockpit service, so that you can start accessing it immediately and so that it starts automatically after a reboot, run the following command:

The service starts and runs a web server that listens on TCP port 9090 by default. You can check the status of the service by running:

Configure Firewall Rules (Optional)

If you are using a custom firewall profile, or an Oracle Cloud Infrastructure instance, open the firewall port for the web console (9090).

To enable the firewall port for the cockpit service and reload the default firewall service on Oracle Linux, run:

Logging into Cockpit

Cockpit serves both HTTP and HTTPS requests on port 9090. By default, Cockpit creates self-signed certificates that are used to facilitate HTTPS. If you use the self-signed certificate, when you go to the web console, the browser displays a security exception warning. To avoid having to grant a security exception, install a certificate signed by a certificate authority (CA) in the /etc/cockpit/ws-certs.d directory. The last file (in alphabetical order) with a .cert extension is used.

Cockpit uses a PAM stack located at /etc/pam.d/cockpit to handle authentication of users. Authentication with PAM allows you to log in with a username and password of any system account that has administrator privileges.

To log into Cockpit:

In a web browser, go to the Cockpit web console using the hostname or IP address of the system at port 9090 using HTTPS. For example:

If you are logging in on the local host, you can use:

If you are not using a signed security certificate, a warning that the connection is not private is displayed. To continue, add an exception for the site in the browser.

Log into Cockpit using a system user account. If the user account has sudo privileges, you can run privileged tasks in the web console. To enable running sudo commands, check the Reuse my password for privileged tasks option. Click Log In. The Cockpit dashboard is displayed.

To connect to a remote Oracle Linux server running Cockpit, use the Connect to field in Other Options and enter the URL for the remote host.
