| # FILE NAME: gpinitsystem_singlenode |
| |
| # A configuration file is needed by the gpinitsystem utility. |
| # This sample file initializes a Greenplum Database Single Node |
| # Edition (SNE) system with one master and two segment instances |
| # on the local host. This file is referenced when you run gpinitsystem. |

| # REQUIRED PARAMETERS |

| |
| # A name for the array you are configuring. You can use any name you |
| # like. Enclose the name in quotes if the name contains spaces. |
| |
| ARRAY_NAME="GPDB SINGLENODE" |
| |
| |
| # This specifies the file that contains the list of segment host names |
| # that comprise the Greenplum system. For a single-node system, this |
| # file contains the local OS-configured hostname (as output by the |
| # hostname command). If the file does not reside in the same |
| # directory where the gpinitsystem utility is executed, specify |
| # the absolute path to the file. |
| |
| MACHINE_LIST_FILE=./hostlist_singlenode |
| |
| |
| # This specifies a prefix that will be used to name the data directories |
| # of the master and segment instances. The naming convention for data |
| # directories in a Greenplum Database system is SEG_PREFIX<number> |
| # where <number> starts with 0 for segment instances and the master |
| # is always -1. So for example, if you choose the prefix gpsne, your |
| # master instance data directory would be named gpsne-1, and the segment |
| # instances would be named gpsne0, gpsne1, gpsne2, gpsne3, and so on. |
| |
| SEG_PREFIX=gpsne |
| |
| |
| # Base port number on which primary segment instances will be |
| # started on a segment host. The base port number will be |
| # incremented by one for each segment instance started on a host. |
| |
| PORT_BASE=40000 |
| |
| |
| # This specifies the data storage location(s) where the script will |
| # create the primary segment data directories. The script creates a |
| # unique data directory for each segment instance. If you want multiple |
| # segment instances per host, list a data storage area for each primary |
| # segment you want created. The recommended number is one primary segment |
| # per CPU. It is OK to list the same data storage area multiple times |
| # if you want your data directories created in the same location. The |
| # number of data directory locations specified will determine the number |
| # of primary segment instances created per host. |
| # You must make sure that the user who runs gpinitsystem (for example, |
| # the gpadmin user) has permissions to write to these directories. You |
| # may want to create these directories on the segment hosts before running |
| # gpinitsystem and chown them to the appropriate user. |

| # The location where the data directory will be created on the |
| # Greenplum master host. |
| # You must make sure that the user who runs gpinitsystem |
| # has permissions to write to this directory. You may want to |
| # create this directory on the master host before running |
| # gpinitsystem and chown it to the appropriate user. |

| MASTER_PORT=5432 |
| |
| |
| # The shell the gpinitsystem script uses to execute |

| # script. You can use gpssh-exkeys to do this. |

| TRUSTED_SHELL=ssh |
| |
| |
| # Maximum distance between automatic write ahead log (WAL) |
| # checkpoints, in log file segments (each segment is normally 16 |

| # Greenplum Database system. |

| # The character set encoding to use. Greenplum supports the |
| # same character sets as PostgreSQL. See 'Character Set Support' |
| # in the PostgreSQL documentation for allowed character sets. |
| # Should correspond to the OS locale specified with the |
