Overview<\/h2>\n

After you create an instance with the cPanel & WHM Amazon Machine Image\u2122 (AMI), you can manage that instance from within the Amazon Web Services\u2122 (AWS) Management Console. This document describes common instance-management tasks that your cPanel & WHM instance may require.<\/p>\n

\n
Note:<\/div>\n
\n
    \n
  • For more information about AWS instance management, read Amazon\u2019s\u00ae Working with the AWS Management Console documentation.<\/li>\n
  • AWS systems may encounter package conflicts when the system attempts to update certain libraries (generally, libstdc++<\/code> libraries). These errors occur due to the way in which AWS manages packages. To resolve this issue, use the yum remove<\/code> or rpm -e<\/code> commands to remove the conflicting package.<\/li>\n
  • For video tutorials about this process, view the cPanel and Amazon AWS playlist on our YouTube channel.<\/li>\n<\/ul><\/div>\n<\/div>\n

    Access your instance for the first time<\/h2>\n
    \n
    Note:<\/div>\n
    \n
      \n
    • To improve security for your system, the cPanel & WHM AMI automatically runs the \/usr\/local\/cpanel\/upcp<\/code> script after the instance initializes. This script may alter the AMI\u2019s version number. Also, the WHM interface may display a license error if you click any update links while the update script runs as a background task.<\/li>\n
    • New instances may require several minutes to initialize. Until the initialization process finishes, the Status Checks<\/em> column of the EC2\u2122 Management Console will display Initializing<\/em> and an hourglass icon.<\/li>\n<\/ul><\/div>\n<\/div>\n

      To access a new instance, perform the following steps:<\/p>\n

        \n
      1. \n

        Sign in to your AWS account.<\/p>\n<\/li>\n

      2. \n

        From the Services<\/em> menu in the top-left corner, select EC2 under Compute<\/em>. The EC2 Management Console<\/em> will appear.<\/p>\n<\/li>\n

      3. \n

        In the left-side menu under Instances<\/em>, click Instances<\/em>. The list of instances will appear.<\/p>\n<\/li>\n

      4. \n

        In the list of instances, or at the bottom of the interface in the Description<\/em> tab, locate the following values:<\/p>\n

          \n
        • \n

          Public DNS (IPv4)<\/em> \u2014 The public DNS address for the instance.<\/p>\n

          \n
          Important:<\/div>\n
          \n

          You must<\/strong> set the hostname correctly before you can license the server.<\/p>\n<\/p><\/div>\n<\/div>\n<\/li>\n

        • \n

          Key Name (Key pair name in the Description tab)<\/em> \u2014 The name of the key pair that you used when you created the instance.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

        • \n

          To connect to the instance via SSH, run the following command, where example<\/code> represents the key pair name and IPADDRESS<\/code> represents the public DNS address:\n<\/p>\n

          \n
          ssh -i \"~\/.ssh\/example.pem\"<\/span> centos@IPADDRESS<\/code><\/pre>\n<\/div>\n<\/li>\n
        • \n
          To escalate to the root<\/code> account, run the sudo su<\/code> command.<\/p>\n<\/li>\n
        • \n
          To change the root<\/code> user\u2019s password, run the passwd<\/code> command. The system will prompt you to enter a new password.<\/p>\n<\/li>\n
        • \n
          Enter the desired password and press Enter<\/em>. The system will prompt you to confirm the password.<\/p>\n<\/li>\n
        • \n
          Reenter the desired password and press Enter<\/em>. A confirmation message will appear.<\/p>\n<\/li>\n
        • \n
          If you wish to access WHM in your browser, perform the following additional steps:<\/p>\n
            \n
          1. \n
            Navigate to the following address, where IPADDRESS<\/code> represents the public DNS address:\n<\/p>\n
            \n
            https:\/\/IPADDRESS:2087<\/code><\/pre>\n<\/div>\n
            \n
            Important:<\/div>\n
            \n
            The cPanel & WHM AMI\u2019s cPanel-provided security group only<\/strong> allows connections via HTTPS.<\/p>\n<\/p><\/div>\n<\/div>\n<\/li>\n
          2. \n
            Use the root<\/code> password to log in to the WHM interface as the root<\/code> user.<\/p>\n<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n
            \n
            More:<\/div>\n
            \n
            For more information, read our How to Access the Command Line and How to Log in to Your Server or Account documentation.<\/p>\n<\/p><\/div>\n<\/div>\n
            Manage instances<\/h2>\n
            \n
            Important:<\/div>\n
            \n
              \n
            • We strongly<\/strong> recommend that you stop unused instances to avoid unnecessary costs.<\/li>\n
            • If you stop an instance, Amazon retains the instance\u2019s basic information, but removes some data. For example, when you restart the instance, AWS will generate a new DNS hostname and IP address.<\/li>\n<\/ul><\/div>\n<\/div>\n
              To start, stop, reboot, or terminate an instance, perform the following steps:<\/p>\n
                \n
              1. \n
                Sign in to your AWS account.<\/p>\n<\/li>\n
              2. \n
                From the Services<\/em> menu in the top-left corner, select EC2 under Compute<\/em>. The EC2 Management Console<\/em> will appear.<\/p>\n<\/li>\n
              3. \n
                In the left-side menu under Instances<\/em>, click Instances<\/em>. The list of instances will appear.<\/p>\n<\/li>\n
              4. \n
                Select the desired instance from the list.<\/p>\n
                \n
                Note:<\/div>\n
                \n
                To update multiple instances, select all of the desired instances.<\/p>\n<\/p><\/div>\n<\/div>\n<\/li>\n
              5. \n
                At the top of the list of instances, click Actions<\/em>. The Actions<\/em> menu will display.<\/p>\n<\/li>\n
              6. \n
                Select the desired setting from the Instance State<\/em> menu:<\/p>\n
                  \n
                • \n
                  Start<\/em> \u2014 Restart the instance, which you must<\/strong> have previously stopped.<\/p>\n<\/li>\n
                • \n
                  Stop<\/em> \u2014 Pause the instance and retain some, but not all, of its data.<\/p>\n<\/li>\n
                • \n
                  Reboot<\/em> \u2014 Reboot the instance.<\/p>\n<\/li>\n
                • \n
                  Terminate<\/em> \u2014 Permanently delete the instance.<\/p>\n
                  \n
                  Warning:<\/div>\n
                  \n
                  When you terminate an instance, the system will delete the instance\u2019s data.<\/p>\n
                    \n
                  • Termination will not<\/strong> delete EBS volumes unless you enable the Delete on Termination<\/em> setting.<\/li>\n
                  • You cannot<\/strong> restore a terminated instance.<\/li>\n<\/ul><\/div>\n<\/div>\n
                     A confirmation message will appear. Confirm your action. The system may require several minutes in order to stop or terminate the instance.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n
                    The Instance State<\/em> column in the list of instances displays the instance\u2019s state and the following status icons:<\/p>\n
                      \n
                    • \n
                      A green icon \u2014 The system has successfully started the instance.<\/p>\n<\/li>\n
                    • \n
                      A yellow icon \u2014 An action is in progress.<\/p>\n<\/li>\n
                    • \n
                      A red icon \u2014 The system has successfully stopped or terminated the instance.<\/p>\n

                      \n
                      After you terminate an instance, that instance will only<\/strong> remain in the list of instances until you refresh the list.<\/p>\n<\/p><\/div>\n<\/div>\n<\/li>\n<\/ul><\/div>\n","protected":false},"excerpt":{"rendered":"
