+HAWQ is pre-installed with a number of client utility applications. You can also run client applications in your HAWQ deployment that were created using standard ODBC/JDBC Application Interfaces.
+
+Alternatively, you may want to provide access to your HAWQ master node from a Linux client outside of your HAWQ cluster. One option to enable this access is to install the full HAWQ binary on the client node. A second option is to create a minimal `psql` client package from an existing HAWQ installation which you could then install on a non-HAWQ client. Refer to [HAWQ psql Client Package](#hawqclient_pkg) for instructions on creating, installing, and running such a package.

All of these options have default values which will be used if the option is not specified. The default host is the local host. The default port number is 5432. The default user name is your OS system user name, as is the default database name. Note that OS user names and HAWQ user names are not necessarily the same.
If the default values are not correct, you can set the environment variables `PGDATABASE`, `PGHOST`, `PGPORT`, and `PGUSER` to the appropriate values, or use a `psql``~/.pgpass` file to contain frequently-used passwords.
+
+## <a id="hawqclient_pkg"></a>HAWQ psql Client Package
+
+You may choose to provide `psql` access to your HAWQ master node from a non-HAWQ Linux client. This section describes the procedures for creating, installing, and running a minimal HAWQ `psql` client package.
+
+### <a id="hawqpsqlclient_pkg_create"></a>Creating the HAWQ psql Client Package
+
+Perform the following steps to create a HAWQ Linux `psql` client package:
+
+1. Log in to a HAWQ node and set up your HAWQ environment:
+
+ ``` shell
+ $ ssh gpadmin@<hawq-node>
+ gpadmin@hawq-node$ . /usr/local/hawq/greenplum_path.sh
+ ```
+
+ **Note**: You can create the client package on any node on which HAWQ is installed.
+
+2. Create working directories:
+
+ ``` shell
+ gpadmin@hawq-node$ mkdir hawqclient
+ gpadmin@hawq-node$ cd hawqclient
+ gpadmin@hawq-node$ export HAWQCLIENTWORKDIR=`pwd`
+ gpadmin@hawq-node$ mkdir bin
+ gpadmin@hawq-node$ mkdir lib
+ ```
+
+3. Copy the HAWQ `psql` client binary and libraries to the appropriate work directories:
+
+ ``` shell
+ gpadmin@hawq-node$ cp $GPHOME/bin/psql $HAWQCLIENTWORKDIR/bin/
+ gpadmin@hawq-node$ cp -d $GPHOME/lib/libpq.* $HAWQCLIENTWORKDIR/lib/
+ ```
+
+4. Generate a runtime environment file for the HAWQ client package:
+
+ ``` shell
+ gpadmin@hawq-node$ echo 'HAWQ_CLIENT=`pwd`
+ export PATH=$HAWQ_CLIENT/bin:$PATH
+ export LD_LIBRARY_PATH=$HAWQ_CLIENT/lib:$LD_LIBRARY_PATH' > ./hawq_client_env.sh
+ ```
+
+ The `hawq_client_env.sh` file sets `$PATH` and `$LD_LIBRARY_PATH` appropriately for a HAWQ client runtime environment.
+
+5. Tar and compress the HAWQ client package:
+
+ ``` shell
+ gpadmin@hawq-node$ cd $HAWQCLIENTWORKDIR/../
+ gpadmin@hawq-node$ tar czvf hawqclient.tar.gz ./hawqclient
+ ```
+
+ These commands create a `hawqclient.tar.gz` file in the current directory.
+
+### <a id="hawqclient_pkg_install"></a>Installing the HAWQ psql Client Package
+
+Perform the following steps to install the HAWQ `psql` client package you created in the previous section on a like Linux-based system:
+
+1. Log in to the client system and create or navigate to the directory in which you want to install the HAWQ client:
+
+ ``` shell
+ $ ssh <user>@<client>
+ user@client$ cd <install-dir>
+ user@client$ export HAWQCLIENTINSTDIR=`pwd`
+ ```
+
+ Make note of the base HAWQ client install directory, you will need this path to run the client.
+
+2. Add the HAWQ client install directory setting to your `.bash_profile` or similar shell login script:
+
+ ``` shell
+ export HAWQCLIENTINSTDIR=<install-dir>
+ ```
+
+ Substitute the full path to your HAWQ client install directory for <install-dir>.
+
+3. Copy the HAWQ client package you created previously to the client system:
+
+ ``` shell
+ user@client$ scp gpadmin@hawq-node:/<dir>/hawqclient.tar.gz .
+ ```
+
+4. Extract the package:
+
+ ``` shell
+ user@client$ tar xzf hawqclient.tar.gz
+ ```
+
+ This command extracts the HAWQ client to `./hawqclient`.
+
+5. Clean up:
+
+ ``` shell
+ user@client$ rm hawqclient.tar.gz
+ ```
+
+### <a id="hawqclient_pkg_run"></a>Running the HAWQ psql Client
+
+Perform the following steps to run a previously-installed HAWQ `psql` client package:
+
+1. Source the HAWQ client environment file (recall the HAWQ client install directory you noted in the previous section):
+
+ ``` shell
+ user@client$ . $HAWQCLIENTINSTDIR/hawqclient/hawq_client_env.sh
+ ```
+
+ `hawq_client_env.sh` sets up the HAWQ client runtime environment, including setting your `$PATH` and `$LD_LIBRARY_PATH` to locate the `psql` client binaries and libraries.
+
+2. Edit your `.bash_profile` or other shell initialization file to source `hawq_client_env.sh` on login. For example, add:
+
+ ``` shell
+ . $HAWQCLIENTINSTDIR/hawqclient/hawq_client_env.sh
+ ```
+
+3. Start the `psql` client. Since the HAWQ master is running on another node, you must identify the HAWQ master hostname. You may also be required to provide the HAWQ master port number if the process is not running on the HAWQ default port. Provide these values via environment variables or on the command line:
+
+ ``` shell
+ user@client$ PGHOST=<master-host> PGPORT=<master-port> psql -d <database-name>
+ ```
+
+ Or:
+
+ ``` shell
+ user@client$ psql -d <database-name> -h <master-host> -p <master-port>
+ ```

-Users can connect to HAWQ using various client applications:
-
-- A number of [HAWQ Client Applications](g-hawq-database-client-applications.html) are provided with your HAWQ installation. The `psql` client application provides an interactive command-line interface to HAWQ.
-- Using standard ODBC/JDBC Application Interfaces, such as ODBC and JDBC, users can connect their client applications to HAWQ.
