pgpool_setup creates a temporary installation of Pgpool-II cluster, which includes a Pgpool-II installation and specified number of PostgreSQL installations under current directory. Current directory must be empty before running pgpool_setup.
pgpool_setup is for testing purpose only and should not be used to create production installations.
Currently pgpool_setup supports streaming replication mode, native replication mode, raw mode and logical replication mode. To support watchdog, see watchdog_setup for details.
pgpool_setup accepts the following command-line arguments:
Specifies the running mode. mode can be r (native replication mode), s (streaming replication mode), n (raw mode), l (logical replication mode) or y (slony mode). If this is omitted, s is assumed.
Specifies the number of PostgreSQL installations. If this is omitted, 2 is used.
Specify the base port number used by Pgpool-II and PostgreSQL. Pgpool-II port is base_port. pcp port is base_port + 1. The first PostgreSQL node's port is base_port + 2, second PostgreSQL node's port is base_port + 3 and so on.
If -pg option is specified, the first PostgreSQL node's port is assigned to pg_base_port, the second PostgreSQL node's port is pg_base_port + 1 and so on.
If this is omitted, 11000 is used.
Specify the base port number used by PostgreSQL. The first PostgreSQL node's port is base_port + 2, second PostgreSQL node's port is base_port + 3 and so on.
If this is omitted, base_port+2 is used.
Do not stop pgpool and PostgreSQL after the work.
Start pgpool with debug mode.
pgpool_setup recognizes following environment variables:
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.
Specifies the path to Pgpool-II configuration files. The default is PGPOOL_INSTALL_DIR/etc.
Specifies the path to PostgreSQL commands such as initdb, pg_ctl and psql. The default is /usr/local/pgsql/bin.
Specifies the path to PostgreSQL shared libraries. The default is /usr/local/pgsql/lib.
Specifies the path to Unix socket directory. The default is /tmp.
Specifies the arguments for initdb command. The default is "--no-locale -E UTF_8".
