# 3.2. 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.
