This part contains reference information for PCP commands. PCP commands are UNIX commands which manipulate pgpool-II via the network. Please note that the parameter format for all PCP commands has been changed since Pgpool-II 3.5.
PCP user names and passwords must be declared in pcp.conf in $prefix/etc directory (see Section 3.2 to know to create the file). -F option can be used when starting Pgpool-II if pcp.conf is placed somewhere else.
The file .pcppass in a user's home directory or the file referenced by environment variable PCPPASSFILE can contain passwords to be used if no password has been specified for the pcp connection (In Pgpool-II 4.4 or before, -w/--no-password option is needed). See pcp_common_options for more details.
This file should contain lines of the following format:
hostname:port:username:password
(You can add a reminder comment to the file by copying the line above and preceding it with #.) Each of the first three fields can be a literal value, or *, which matches anything. The password field from the first line that matches the current connection parameters will be used. (Therefore, put more-specific entries first when you are using wildcards.) If an entry needs to contain : or \, escape this character with \. The hostname field is matched to the host connection parameter if that is specified, if the host parameter is not given then the host name localhost is searched for. The host name localhost is also searched for when the connection is a Unix domain socket connection and the host parameter matches the default pcp socket directory path.
The permissions on .pcppass must disallow any access to world or group; achieve this by the command chmod 0600 ~/.pcppass. If the permissions are less strict than this, the file will be ignored.
