  4. Accessing the newly created OCI instances.

Reboot or start the instance.

After the console screen is blank, there is only one or two seconds to press <escape key>. Press it several times as quickly as possible.

If escape was pressed successfully, the Boot menu will be displayed, if not try again.

Note that it is possible that instead of the Boot menu, a BIOS is displayed:

In that case, navigate to “Continue”, press Enter followed by Escape.

Enable Password based authenticaiton in OCI compute instance

by

If you want to use a password to access the SSH server, a solution for fixing the Permission denied error is to enable password login in the sshd_config file.

To do this, open the file in a text editor.  This example uses the nano editor:

sudo nano /etc/ssh/sshd_config

In the file, find the PasswordAuthentication line and make sure it ends with yes.

Find the ChallengeResponseAuthentication option and disable it by adding no.

If lines are commented out, remove the hash sign # to uncomment them. Save the file and exit. Restart the SSH service by typing the following command:

sudo systemctl restart sshd

Oracle OCI-CLI requires Python packages v 3.6 or higher. During installation it is auto installed on windows server/OS, however on Linux, there might be preinstalled Python package installed, that might need to be updated manually before running the installer. (In few cases, the installation failed and the package needed to be be updated seperately)

Installation on Linux

bash -c "$(curl -L https://raw.githubusercontent.com/oracle/oci-cli/master/scripts/install/install.sh)"

For CentOS-7 few additional steops might needed-

sudo yum groupinstall 'Development Tools'
sudo yum install centos-release-scl
sudo yum install rh-python36
scl enable rh-python36 bash
yum -y install python-pip

afterwards, run the installer command mentioned above.
