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(1) as a workhorse.
Currently watchdog_setup supports streaming replication mode, snapshot isolation mode,
native replication mode, logical 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 watchdog_base_port + 1,
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), i (snapshot
isolation mode), s (streaming replication mode), l (logical 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".
