Connecting to a Compute Node Through Secure Shell (SSH)
You use Secure Shell (SSH) client software to establish a secure connection and gain local access the tools, utilities, and other resources on an Oracle Database Exadata Cloud at Customer compute node.
By default, Exadata Cloud at Customer
is configured to enable SSH connections using the opc
and
oracle
operating system user accounts. For tasks that use other
operating system user accounts, you can start a command shell as the
root
user by connecting to opc
and running
sudo -s
.
Several SSH clients are freely available. The following sections show how to use SSH clients on UNIX, UNIX-like, and Windows platforms to connect to a compute node associated with Exadata Cloud at Customer.
Connecting to a Compute Node Using the ssh Utility on UNIX and UNIX-Like Platforms
UNIX and UNIX-like platforms (including Solaris and Linux) include the ssh utility, an SSH client.
Before You Begin
Before you use the ssh utility to connect to a compute node, you need the following:
-
The IP address of the compute node
The IP address of a compute node associated with a database deployment on Oracle Database Exadata Cloud at Customer is listed on the Oracle Database Cloud Service Overview page. See Viewing Detailed Information for a Database Deployment.
-
The SSH private key file that matches the public key associated with the deployment.
Procedure
Connecting to a Compute Node Using the PuTTY Program on Windows
PuTTY is a freely available SSH client program for Windows.
Before You Begin
Before you use the PuTTY program to connect to a compute node, you need the following:
-
The IP address of the compute node
The IP address of a compute node associated with a database deployment on Oracle Database Exadata Cloud at Customer is listed on the Oracle Database Cloud Service Overview page. See Viewing Detailed Information for a Database Deployment.
-
The SSH private key file that matches the public key associated with the deployment. This private key file must be in the PuTTY .ppk format. If the private key file was originally created on the Linux platform, you can use the PuTTYgen program to convert it to the .ppk format.
