The Greenplum Platform Extension Framework (PXF) for Greenplum Database 5.21.2+ and 6.x for CentOS 7.x and RHEL 7.x platforms is available from a separately-downloadable package on Pivotal Network.
The PXF download package is an
.rpm file that installs PXF libraries, executables, and script files on a Greenplum Database host.
When you install PXF, you will:
- Satisfy the prerequisites.
- Download the PXF package.
- Install the PXF
.rpmon every host in your Greenplum Database cluster.
- Check out Next Steps for post-install topics.
The recommended deployment model is to install PXF on all Greenplum Database hosts. Before you install PXF, ensure that you meet the following prerequisites:
- Greenplum version 5.21.2 or later or 6.x is installed in the cluster.
- You have access to all hosts (master, standby master, and segment hosts) in your Greenplum Database cluster.
- You must be an operating system superuser, or have
sudoor other privileges, to install the PXF package in the default location
/usr/local/pxf-gp<greenplum-major-version>. Or, you can choose to install the package into a directory in which you do have access by specifying the
--prefixoption to the install command.
- You have installed Java 8 or 11 on all Greenplum Database hosts as described in Installing Java for PXF.
- You can identify the operating system user that will own the PXF installation. This user must be the same user that owns the Greenplum Database installation, or a user that has write privileges to the Greenplum Database installation directory.
- If you have previously configured and are using PXF in your Greenplum installation:
- Identify and note the current PXF version number.
- Stop PXF as described in Stopping PXF.
$GPHOME/pxfdirectory exists in your Greenplum installation, you may choose to remove the directory on all Greenplum hosts after you confirm that you have installed and configured PXF correctly and that it is working as expected.
If you choose to remove this directory, you may encounter
warning: <pxf-filename>: remove failed: No such file or directory messages when you upgrade Greenplum. You can ignore these warnings for PXF files.
PXF is available as a separate download for Greenplum Database 5.x or 6.x for CentOS 7.x and RHEL 7.x platforms from Pivotal Network:
Download the package by navigating to Pivotal Network and locating and selecting the Release Download directory named Greenplum Platform Extension Framework.
The format of the PXF download filename is
pxf-gp<greenplum-major-version>-<pxf-version>.<platform>.<file_type>. For example:
Make note of the directory to which the file was downloaded.
You must install the PXF package on the Greenplum Database master and standby master hosts, and on each segment host.
The install procedure follows:
Locate the installer file that you downloaded from Pivotal Network.
Create a text file that lists your Greenplum Database standby master host and segment hosts, one host name per line. For example, a file named
gpmaster mstandby seghost1 seghost2 seghost3
Install the package on each Greenplum Database host using your package management utility. If a previous installation of PXF exists for the same Greenplum version, the files and runtime directories from the older version are removed before the current package is installed.
To install PXF into the default location on all Greenplum hosts:
Install the package. For example, if you are installing PXF for Greenplum 6 on a CentOS 7 system:
gphost$ gpssh -e -v -f gphostfile sudo rpm -Uvh pxf-gp6-5.13.0-1.el7.x86_64.rpm
When you install the PXF
.rpmpackage to the default location, PXF is installed to
Set the ownership and permissions of the PXF installation files to enable access by the
gphost$ gpssh -e -v -f gphostfile sudo chown -R gpadmin:gpadmin /usr/local/pxf-gp*
To install PXF into a custom location on all Greenplum hosts as a non-root user:
gpadmin@gphost$ gpssh -e -v -f gphostfile rpm -Uvh pxf-gp6-5.13.0-1.el7.x86_64.rpm --prefix <install-location>
(Optional) Add the PXF
bindirectory to the PXF owner’s
$PATH. For example, if you installed PXF for Greenplum 6 in the default location, you could add the following text to the
.bash_profileshell initialization script for the
Be sure to remove any previously-added
$PATHentries for PXF in
PXF is not active after installation. You must explicitly initialize and start the PXF server before you can use PXF.
- See About the PXF Installation and Configuration Directories for a list and description of important PXF files and directories.
- If this is your first time using PXF, review Configuring PXF for a description of the initialization and configuration procedures that you must perform before you can use PXF.
- If you installed the PXF
.rpminto a Greenplum cluster in which you had already configured and were using PXF, you may be required to perform some upgrade actions. Recall the original version of PXF (before you installed the
.rpm), and perform Step 2 of the PXF upgrade procedure.
