This page lists some conventions and notations used in this documentation.

Using sudo

Throughout this document, we’re assuming that commands which require root permissions can be issued by using sudo. If your system is not configured for this, you can either login directly as root (considered as “bad practice”) or use the su - command to switch to the root user.

note We highly recommend the usage of sudo though!

Operating systems

We will use visual shortcuts to refer to the operating system families supported by the HRM, as in the following table:

Icon Corresponding operating system family
fedora Fedora, CentOS, RHEL
ubuntu Ubuntu and derivatives


Support for macosx Mac OS X was dropped in HRM version 3.1.


Variable Description (Example) value
$WWW_ROOT Web server document root /var/www/html
$HRM_HOME HRM root (home) folder $WWW_ROOT/hrm
$HRM_CONFIG HRM configuration folder $HRM_HOME/config
$HRM_SAMPLES HRM configuration samples folder $HRM_HOME/config/samples
$HRM_RESRC HRM resources folder $HRM_HOME/resources
$HRM_SETUP HRM setup folder $HRM_HOME/setup
$HRM_BIN HRM executables folder $HRM_HOME/bin
$HRM_USER HRM customization folder $HRM_HOME/user
$HRM_DATA HRM data folder /data/hrm_data

If you want to use those variables in your interactive shell later on, just copy-paste the following lines into your session and adjust the values accordingly:

WWW_ROOT=/var/www/html                 # Web server document root
HRM_HOME=$WWW_ROOT/hrm                 # HRM root (home) folder
HRM_CONFIG=$HRM_HOME/config            # HRM configuration folder
HRM_SAMPLES=$HRM_HOME/config/samples   # HRM configuration samples folder
HRM_RESRC=$HRM_HOME/resources          # HRM resources folder
HRM_SETUP=$HRM_HOME/setup              # HRM setup folder
HRM_BIN=$HRM_HOME/bin                  # HRM executables folder
HRM_USER=$HRM_HOME/user                # HRM customization folder
HRM_LOG=/var/log/hrm                   # HRM logging folder
HRM_DATA=/data/hrm_data                # HRM data folder


Please notice that $WWW_ROOT is /var/www/html in fedora and in ubuntu as of version 14.04 LTS. In earlier versions of ubuntu, however, $WWW_ROOT used to be /var/www.
