Configure node web console

The web console can be configured in Bare Metal service in the following way:

• Install shellinabox in ironic conductor node. For RHEL/CentOS, shellinabox package is not present in base repositories, user must enable EPEL repository, you can find more from FedoraProject page.

  Installation example:

  Ubuntu:
      sudo apt-get install shellinabox
  
  Fedora 21/RHEL7/CentOS7:
      sudo yum install shellinabox
  
  Fedora 22 or higher:
       sudo dnf install shellinabox

  You can find more about shellinabox on the shellinabox page.

  You can optionally use the SSL certificate in shellinabox. If you want to use the SSL certificate in shellinabox, you should install openssl and generate the SSL certificate.

  1. Install openssl, for example:

     Ubuntu:
          sudo apt-get install openssl
     
     Fedora 21/RHEL7/CentOS7:
          sudo yum install openssl
     
     Fedora 22 or higher:
          sudo dnf install openssl

  2. Generate the SSL certificate, here is an example, you can find more about openssl on the openssl page:

     cd /tmp/ca
     openssl genrsa -des3 -out my.key 1024
     openssl req -new -key my.key  -out my.csr
     cp my.key my.key.org
     openssl rsa -in my.key.org -out my.key
     openssl x509 -req -days 3650 -in my.csr -signkey my.key -out my.crt
     cat my.crt my.key > certificate.pem

• Customize the console section in the Bare Metal service configuration file (/etc/ironic/ironic.conf), if you want to use SSL certificate in shellinabox, you should specify terminal_cert_dir. for example:

  [console]
  
  #
  # Options defined in ironic.drivers.modules.console_utils
  #
  
  # Path to serial console terminal program (string value)
  #terminal=shellinaboxd
  
  # Directory containing the terminal SSL cert(PEM) for serial
  # console access (string value)
  terminal_cert_dir=/tmp/ca
  
  # Directory for holding terminal pid files. If not specified,
  # the temporary directory will be used. (string value)
  #terminal_pid_dir=<None>
  
  # Time interval (in seconds) for checking the status of
  # console subprocess. (integer value)
  #subprocess_checking_interval=1
  
  # Time (in seconds) to wait for the console subprocess to
  # start. (integer value)
  #subprocess_timeout=10

• Append console parameters for bare metal PXE boot in the Bare Metal service configuration file (/etc/ironic/ironic.conf), including right serial port terminal and serial speed, serial speed should be same serial configuration with BIOS settings, so that os boot process can be seen in web console, for example:

  pxe_* driver:
  
       [pxe]
  
       #Additional append parameters for bare metal PXE boot. (string value)
       pxe_append_params = nofb nomodeset vga=normal console=tty0 console=ttyS0,115200n8

• Configure node web console.

  Enable the web console, for example:

  ironic node-update <node-uuid> add driver_info/<terminal_port>=<customized_port>
  ironic node-set-console-mode <node-uuid> true

  Check whether the console is enabled, for example:

  ironic node-validate <node-uuid>

  Disable the web console, for example:

  ironic node-set-console-mode <node-uuid> false
  ironic node-update <node-uuid> remove driver_info/<terminal_port>

  The <terminal_port> is driver dependent. The actual name of this field can be checked in driver properties, for example:

  ironic driver-properties <driver>

  For *_ipmitool and *_ipminative drivers, this option is ipmi_terminal_port. For seamicro driver, this option is seamicro_terminal_port. Give a customized port number to <customized_port>, for example 8023, this customized port is used in web console url.

• Get web console information:

  ironic node-get-console <node-uuid>
  +-----------------+----------------------------------------------------------------------+
  | Property        | Value                                                                |
  +-----------------+----------------------------------------------------------------------+
  | console_enabled | True                                                                 |
  | console_info    | {u'url': u'http://<url>:<customized_port>', u'type': u'shellinabox'} |
  +-----------------+----------------------------------------------------------------------+

  You can open web console using above url through web browser. If console_enabled is false, console_info is None, web console is disabled. If you want to launch web console, refer to Enable web console part.
