Configuring pcp.conf

Pgpool-II provides a interface for administrators to perform management operation, such as getting Pgpool-II status or terminating Pgpool-II processes remotely. pcp.conf is the user/password file used for authentication by this interface. All operation modes require the pcp.conf file to be set. A $prefix/etc/pcp.conf.sample file is created during the installation of Pgpool-II . Copy the file as $prefix/etc/pcp.conf and add your user name and password to it.

$ cp $prefix/etc/pcp.conf.sample $prefix/etc/pcp.conf
	  

An empty line or a line starting with # is treated as a comment and will be ignored. A user name and its associated password must be written as one line using the following format:

username:[md5 encrypted password]
	  

[md5 encrypted password] can be produced with the $prefix/bin/pg_md5 command.

$ pg_md5 your_password
1060b7b46a3bd36b3a0d66e0127d0517
      

If you don't want pass the password as the argument, execute pg_md5 -p .

$ pg_md5 -p
password: your_password
      

The pcp.conf file must be readable by the user who executes Pgpool-II .
