Graphite renders graphs using the Cairo graphics library. This adds dependencies on several graphics-related libraries not typically found on a server. If you’re installing from source you can use the check-dependencies.py script to see if the dependencies have been met or not.
Basic Graphite requirements:
Python 2.5 has extra requirements:
Additionally, the Graphite webapp and Carbon require the whisper database library which is part of the Graphite project.
There are also several other dependencies required for additional features:
On some systems it is necessary to install fonts for Cairo to use. If the webapp is running but all graphs return as broken images, this may be why.
Most current Linux distributions have all of the requirements available in the base packages. RHEL based distributions may require the EPEL repository for requirements. Python module dependencies can be install with pip rather than system packages if desired or if using a Python version that differs from the system default. Some modules (such as Cairo) may require library development headers to be available.
Graphite defaults to an installation layout that puts the entire install in its own directory: /opt/graphite
Whisper is installed Python’s system-wide site-packages directory with Whisper’s utilities installed in the bin dir of the system’s default prefix (generally /usr/bin/).
Carbon and Graphite-web are installed in /opt/graphite/ with the following layout:
Log directory for Carbon and Graphite-web
Location for RRD files to be read
Location for Whisper data files to be stored and read
Location of local_settings.py
Graphite-web static content directory
Several installation options exist:
