Quick start how-to graphite base install on Debian

UPDATE: Also see Latest Graphite on Amazon Linux at AWS.

This only gets graphite working on your local Linux box. Left to user to translate to remote server installation thereafter.

NOTE: Do everything as root user

  1. make sure apache2 is installed and working with wsgi
    1. apt-get install apache2 -y
    2. apt-get install libapache2-mod-wsgi -y
    3. a2enmod wsgi
    4. wsgi needs a place for its sockets
      1. mkdir /etc/apache2/run
      2. mkdir /var/run/wsgi
      3. chmod 777 /etc/apache2/run /var/run/wsgi
      4. this seems undocumented, thanks!
  2. Install dependencies
    1. apt-get install -y libapache2-mod-wsgi python-twisted python-memcache python-pysqlite2 python-simplejson
    2. apt-get install -y python2.6 python-pip python-cairo python-django python-django-tagging
  3. Install graphite elements
    1. mkdir -p /root/graphite-install
    2. cd /root/graphite-install
    3. git clone https://github.com/graphite-project/graphite-web.git
    4. git clone https://github.com/graphite-project/carbon.git
    5. git clone https://github.com/graphite-project/whisper.git
    6. git clone https://github.com/graphite-project/ceres
    7. cd /root/graphite-install/whisper
    8. git checkout 0.9.x
    9. python setup.py install
    10. cd /root/graphite-install/ceres
    11. python setup.py install
    12. cd /root/graphite-install/carbon
    13. git checkout 0.9.x
    14. python setup.py install
    15. cd /root/graphite-install/graphite-web
    16. git checkout 0.9.x
    17. python check-dependencies.py
      1. fix any missing dependencies
      2. ignore warnings if certain you don't need a feature
    18. python setup.py install
  4. Setup configuration files and permissions
    1. cp -v /opt/graphite/conf/carbon.conf.example /opt/graphite/conf/carbon.conf
    2. cp -v /opt/graphite/conf/storage-schemas.conf.example /opt/graphite/conf/storage-schemas.conf
    3. Create Django database
      1. cp -v /opt/graphite/webapp/graphite/local_settings.py.example /opt/graphite/webapp/graphite/local_settings.py
        1. Edit this file by uncommenting the entire DATABASES section
          1. Otherwise next commands may fail with bizarre error
      2. cd /opt/graphite/webapp/graphite
      3. python manage.py syncdb
        1. Make sure NO errors
        2. Create a user/pass you'll never forget
    4. chown -Rv www-data:www-data /opt/graphite/storage/
  5. Apache
    1. Add below Apache configuration as a virtual host (details not covered here)
      1. Or do this and struggle to make it work
        1. cp -v /opt/graphite/examples/example-graphite-vhost.conf /etc/apache2/sites-available/graphite
    2. Every "directory" and "location" in the virtual hosts file need these entries, or you'll get permission denied errors
      1. apache versions before 2.4
        1. Order deny,allow
        2. Allow from all
      2. apache versions 2.4 and after
        1. Require all granted
    3. a2ensite graphite
    4. cp -v /opt/graphite/conf/graphite.wsgi.example /opt/graphite/conf/graphite.wsgi
    5. apache2ctl -S
      1. Check all is OK
    6. service apache2 stop
    7. service apache2 start
    8. If you have trouble check permissions under this directory and/or run this again
      1. chown -Rv www-data:www-data /opt/graphite/storage/
      2. Seems some files are created by root that should be created by www-data user maybe
  6. Start carbon daemon
    1. cd /opt/graphite
    2. /opt/graphite/bin/carbon-cache.py start
      1. verify with:
        1. lsof -nP -i :2003
      2. TASK: automate this to start on reboot somehow
  7. Add to /etc/hosts
    1. graphite
  8. tail -F /opt/graphite/storage/log/webapp/error.log
  9. python /opt/graphite/examples/example-client.py
  10. Hit http://graphite
    1. Should show initial graphite interface
  11. View results
    1. Click down into "system" -> loadavg_5min
    2. Find "Select Recent Data" icon in upper-left toolbar
      1. Set to 10 mins
    3. You should see lines appearing as script runs and feed data to Graphite via Carbon
  12. Check out giraffe once you get some stats to shove in it
    1. https://github.com/kenhub/giraffe
    2. Just dump the files you get from the git clone into a directory under you default Apache install and tweedle with dashboard.js until you see something
  13. Try this a few times on the CLI of your graphite server every few minutes
    1. echo "system.logs.changed_last10 `find /var/log -mmin -10 | wc -l` `date +%s`" | nc -w 1 localhost 2003
    2. Try similar commands to pass in other stats
      1. echo must output a single integer.
