Description

The `create-node-ssh` subcommand creates a node that is enabled for communication over secure shell (SSH).

A node represents a host on which the GlassFish Server software is installed. A node must exist for every host on which GlassFish Server instances reside.

The domain administration server (DAS) contacts an SSH node's host through the SSH connector to manage GlassFish Server instances that reside on the node. However, the DAS does not use the SSH connector to contact the host where the DAS is running because the DAS can run all `asadmin` subcommands locally.

By default, the subcommand fails and the node is not created if the DAS cannot contact the node's host through SSH. To force the node to be created in the DAS configuration even if the host cannot be contacted through SSH, set the `--force` option to `true`.

This subcommand is supported in remote mode only.

Options

`--help`
`-?`

  Displays the help text for the subcommand.

`--nodehost`

  The name of the host that the node represents. The name of the host must be specified. Otherwise, an error occurs.

`--installdir`

  The full path to the parent of the base installation directory of the GlassFish Server software on the host, for example, `/export/glassfish3/`. The default is the parent of the default base installation directory of the GlassFish Server software for the DAS. This default is useful only if GlassFish Server is installed in the same location on all hosts.

`--nodedir`

  The path to the directory that is to contain GlassFish Server instances that are created on the node. The default is as-install`/nodes`, where as-install is the base installation directory of the GlassFish Server software on the host. If a relative path is specified, the path is relative to the as-install directory.

`--sshport`

  The port to use for SSH connections to this node's host. The default is 22. If the `--nodehost` option is set to `localhost-`domain, the `--sshport` option is ignored.

`--sshuser`

  The user on this node's host that is to run the process for connecting to the host through SSH. The default is the user that is running the DAS process. To ensure that the DAS can read this user's SSH private key file, specify the user that is running the DAS process. If the `--nodehost` option is set to `localhost-`domain, the `--sshuser` option is ignored.

`--sshkeyfile`

  The absolute path to the SSH private key file for user that the `--sshuser` option specifies. This file is used for authentication to the `sshd` daemon on the node's host.

  Note:

  GlassFish Server also supports password authentication through the `AS_ADMIN_SSHPASSWORD` entry in the password file. The password file is specified in the `--paswordfile` option of the asadmin(1M) utility.

  If the SSH private key file is protected by a passphrase, the password file must contain the `AS_ADMIN_SSHKEYPASSPHRASE` entry.

  The path to the key file must be reachable by the DAS and the key file must be readable by the DAS.

  The default is the a key file in the user's `.ssh` directory. If multiple key files are found, the subcommand uses the following order of preference:

  1. `id_rsa`

  2. `id_dsa`

  3. `identity`

`--force`

  Specifies whether the node is created in the DAS configuration even if validation of the node's parameters fails. To validate a node's parameters, the DAS must be able to contact the node's host through SSH. Possible values are as follows:

  `false`

    The node is not created if validation of the node's parameters fails (default).

  `true`

    The node is created even if validation of the node's parameters fails.

`--install`

  Specifies whether the subcommand shall install the GlassFish Server software on the host that the node represents.

  Possible values are as follows:

  `false`

    The subcommand shall not install the GlassFish Server software on the host (default).

  `true`

    The subcommand shall install the GlassFish Server software on the host.

`--archive`

  The absolute path to the archive file of the GlassFish Server software that is to be installed. If this option is omitted and the `--install` is `true`, the subcommand creates a ZIP archive of the GlassFish Server software from the installation where this subcommand is run. The archive does not contain the `domains` directory or the `nodes` directory.

Operands

node-name

  The name of the node.

  The name must meet the following requirements:

  - The name may contain only ASCII characters.

  - The name must start with a letter, a number, or an underscore.

  - The name may contain only the following characters:

    - Lowercase letters

    - Uppercase letters

    - Numbers

    - Hyphen

    - Period

    - Underscore

  - The name must be unique in the domain and must not be the name of another node, a cluster, a named configuration, or a GlassFish Server instance.

  - The name must not be `domain`, `server`, or any other keyword that is reserved by GlassFish Server.

Examples

Example 1 Creating a Node

  This example creates the node `adc` for the host `adc.example.com`. By default, the parent of the base installation directory of the GlassFish Server software is `/export/glassfish3`.

      asadmin> create-node-ssh
      --nodehost adc.example.com
      --installdir /export/glassfish3 adc

      Command create-node-ssh executed successfully.

Example 2 Forcing the Creation of a Node

  This example forces the creation of node `eg1` for the host `eghost.example.com`. The node is created despite the failure of the DAS to contact the host `eghost.example.com` to validate the node's parameters.

      asadmin> create-node-ssh --force --nodehost eghost.example.com eg1
      Warning: some parameters appear to be invalid.
      Could not connect to host eghost.example.com using SSH.
      There was a problem while connecting to eghost.example.com:22
      eghost.example.com
      Continuing with node creation due to use of --force.

      Command create-node-ssh executed successfully.

Exit Status

0

  command executed successfully

1

  error in executing the command
