`repmgr` and `repmgrd` use a common configuration file, by default called `repmgr.conf` (although any name can be used if explicitly specified). `repmgr.conf` must contain a number of required parameters, including the database connection string for the local node and the location of its data directory; other values will be inferred from defaults if not explicitly supplied. See section `configuration file parameters` for more details. The configuration file will be searched for in the following locations: a configuration file specified by the `-f/--config-file` command line option a location specified by the package maintainer (if `repmgr` was installed from a package and the package maintainer has specified the configuration file location) `repmgr.conf` in the local directory `/etc/repmgr.conf` the directory reported by `pg_config --sysconfdir` Note that if a file is explicitly specified with `-f/--config-file`, an error will be raised if it is not found or not readable and no attempt will be made to check default locations; this is to prevent `repmgr` unexpectedly reading the wrong file.
