# watchdog_setup

## Name

watchdog_setup -- Create a temporary installation of Pgpool-II clusters with watchdog

## Synopsis

`watchdog_setup` [`option`...]

## Description

watchdog_setup creates a temporary installation of Pgpool-II clusters with watchdog enabled, which includes a Pgpool-II installation and specified number of PostgreSQL installations under current directory. Current directory must be empty before running watchdog_setup.

watchdog_setup is for testing purpose only and should not be used to create production installations. Also please note that heartbeat is not used.

watchdog_setup uses pgpool_setup as a workhorse.

Currently watchdog_setup supports streaming replication mode, native replication mode and raw mode.

## Options

watchdog_setup accepts the following command-line arguments:

`-wn `num_pgpool``

  Specifies the number of Pgpool-II installations. If this is omitted, `3` is used.

`-wp `watchdog_base_port``

  Specify the starting base port number used by Pgpool-II and PostgreSQL. For the first Pgpool-II, Pgpool-II port is watchdog_base_port. pcp port is u watchdog port is watchdog_base_port + 2. wd_heartbeat_port is watchdog_base_port + 3 (though heartbeat is not used). The first PostgreSQL node's port is watchdog_base_port + 4, second PostgreSQL node's port is watchdog_base_port + 5 and so on.

  If this is omitted, `50000` is used.

`-m `mode``

  Specifies the running mode. `mode` can be `r` (native replication mode), `s` (streaming replication mode), or `n` (raw mode). If this is omitted, `s` is used.

`-n `num_clusters``

  Specifies the number of PostgreSQL installations. If this is omitted, `2` is used.

`--no-stop`

  Do not stop pgpool and PostgreSQL after the work.

`-d`

  Start pgpool with debug mode.

## Environment variables

watchdog_setup recognizes following environment variables:

`PGPOOL_SETUP`

  Specifies the path to pgpool_setup command. The default is "pgpool_setup", thus it is assumed that pgpool_setup is in the command search path.

`PGPOOL_INSTALL_DIR`

  Specifies the Pgpool-II installation directory. Pgpool-II binaries is expected to be placed under PGPOOL_INSTALL_DIR/bin and pgpool.conf and pool_hba.conf etc. are expected to be placed under PGPOOL_INSTALL_DIR/etc. The default is /usr/local.

`PGPOOLDIR`

  Specifies the path to Pgpool-II configuration files. The default is PGPOOL_INSTALL_DIR/etc.

`PGBIN`

  Specifies the path to PostgreSQL commands such as initdb, pg_ctl and psql. The default is /usr/local/pgsql/bin.

`PGLIB`

  Specifies the path to PostgreSQL shared libraries. The default is /usr/local/pgsql/lib.

`PGSOCKET_DIR`

  Specifies the path to Unix socket directory. The default is /tmp.

`INITDBARG`

  Specifies the arguments for initdb command. The default is "--no-locale -E UTF_8".
