Description

The create-http-listener command creates an HTTP listener. This command is supported in remote mode only.

---

Note –

If you edit the special HTTP listener named admin-listener, you must restart the server for the changes to take effect. The Administration Console does not tell you that a restart is required in this case.

---

Options

-t --terse

Indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well-formatted data for consumption by a script. Default is false.

-e --echo

Setting to true will echo the command line statement on the standard output. Default is false.

-I --interactive

If set to true (default), only the required password options are prompted.

-H --host

The machine name where the domain administration server is running. The default value is localhost.

-p --port

The HTTP/S port for administration. This is the port to which you should point your browser in order to manage the domain. For example, http://localhost:4848.

The default port number is 4848.

-s --secure

If set to true, uses SSL/TLS to communicate with the domain administration server.

-u --user

The authorized domain administration server administrative username.

If you have authenticated to a domain using the asadmin login command, then you need not specify the --user option on subsequent operations to this particular domain.

--passwordfile

The --passwordfile option specifies the name, including the full path, of a file containing the password entries in a specific format. The entry for the password must have the AS_ADMIN_ prefix followed by the password name in uppercase letters.

For example, to specify the domain administration server password, use an entry with the following format: AS_ADMIN_PASSWORD=password, where password is the actual administrator password. Other passwords that can be specified include AS_ADMIN_MAPPEDPASSWORD, AS_ADMIN_USERPASSWORD, and AS_ADMIN_ALIASPASSWORD.

All remote commands must specify the admin password to authenticate to the domain administration server, either through --passwordfile or asadmin login, or interactively on the command prompt. The asadmin login command can be used only to specify the admin password. For other passwords, that must be specified for remote commands, use the --passwordfile or enter them at the command prompt.

If you have authenticated to a domain using the asadmin login command, then you need not specify the admin password through the --passwordfile option on subsequent operations to this particular domain. However, this is applicable only to AS_ADMIN_PASSWORD option. You will still need to provide the other passwords, for example, AS_ADMIN_USERPASSWORD, as and when required by individual commands, such as update-file-user.

For security reasons, passwords specified as an environment variable will not be read by asadmin.

The default value for AS_ADMIN_MASTERPASSWORD is changeit.

--help

Displays the help text for the command.

--listeneraddress

The IP address or the hostname (resolvable by DNS).

--listenerport

The port number to create the listen socket on. Legal values are 1–65535. On UNIX, creating sockets that listen on ports 1–1024 requires superuser privileges. Configuring an SSL listen socket to listen on port 443 is recommended.

--defaultvs

The ID attribute of the default virtual server for this listener.

--servername

Tells the server what to put in the host name section of any URLs it sends to the client. This affects URLs the server automatically generates; it doesn't affect the URLs for directories and files stored in the server. This name should be the alias name if your server uses an alias. If a colon and port number are appended, that port will be used in URLs that the server sends to the client.

--acceptorthreads

The number of acceptor threads for the listen socket. The recommended value is the number of processors in the machine. The default value is 1.

--xpowered

If set to true, adds the X-Powered-By: Servlet/2.4 and X-Powered-By: JSP/2.0 headers to the appropriate responses. The Servlet 2.4 specification defines the X-Powered-By: Servlet/2.4 header, which containers may add to servlet-generated responses. Similarly, the JSP 2.0 specification defines the X-Powered-By: JSP/2.0 header, which containers may add to responses that use JSP technology. The goal of these headers is to aid in gathering statistical data about the use of Servlet and JSP technology.

--redirectport

This option is valid only in domains that are configured to support clusters Port number for redirects. If the HTTP listener is supporting non-SSL requests, and a request is received for which a matching security-constraint requires SSL transport, the Communications Server will automatically redirect the request to this port number.

--securityenabled

If set to true, the HTTP listener runs SSL. You can turn SSL2 or SSL3 ON or OFF and set ciphers using an SSL element. The security setting globally enables or disables SSL by making certificates available to the server instance. The default value is false.

--enabled

If set to true, the listener is enabled at runtime.

--target

This option is valid only in domains that are configured to support clusters Specifies the target for which you are creating the HTTP listener. Valid values are

• server- Specifies the default server instance as the target for creating the listener. server is the name of the default server instance and is the default value for this option.

• configuration_name- Specifies a particular configuration as the target for creating the listener.

• cluster_name- Specifies all the server instances in a particular cluster as the targets for creating the listener.

• stand-alone_instance_name- Specifies a particular server instance as the target for creating the listener.

Operands

listener_id

The listener ID of the HTTP listener.

Example 1 Using the create-http-listener command




The following command creates an HTTP listener named sampleListener that uses a nondefault number of acceptor threads and is not enabled at runtime:

asadmin> create-http-listener --user admin1 --passwordfile passwords.txt --host host1 --port 4848 --listeneraddress 0.0.0.0 --listenerport 7272 --defaultvs server --servername host1.sun.com --acceptorthreads 100 --securityenabled=false --enabled=false sampleListener Command create-http-listener executed successfully.
