rpm -Uvh whisper-0.9.7-1.noarch.rpm
rm -rf whisper*.rpm

-- Install Carbon - the Graphite back-end ---

wget "http://launchpad.net/graphite/1.0/0.9.7/+download/carbon-0.9.7-1.noarch.rpm"
rpm -Uvh carbon-0.9.7-1.noarch.rpm
cp /opt/graphite/conf/carbon.conf.example /opt/graphite/conf/carbon.conf
cp /opt/graphite/conf/storage-schemas.conf.example /opt/graphite/conf/storage-schemas.conf
rm -rf carbon*.rpm

rm -rf graphite-web*.rpm

Add 8125:udp to firewall

copy the local_settings example file to creating the app's settings

this is where both carbon federation and authentication is configured

cp /opt/graphite/webapp/graphite/local_settings.py.example \
   /opt/graphite/webapp/graphite/local_settings.py

===== BEGIN MANUAL STEP =====

run syncdb to setup the db and prime the authentication model (if you're using the DB model)

python /opt/graphite/webapp/graphite/manage.py syncdb

Create super user

===== END MANUAL STEP =====

change ownership of the storage folder to the Apache user/group

chown -R apache:apache /opt/graphite/storage/

Config graphite /opt/graphite/conf

Set up init.d

wget https://gist.github.com/raw/1071989/32b8da693933ccc5b04445c13ec280a622f61400/carbon.init.sh
mv carbon.init.sh /etc/init.d/carbon
chmod 0755 /etc/init.d/carbon
chkconfig --add carbon

Add virtual host to apache.conf

service httpd start

--- Install StatsD ---

cd /opt
git clone git://github.com/etsy/statsd.git
cd statsd

copy the the statsd config example to create the config file

unless you used non-default ports for some other feature of the system, the defaults in the config file are fine

cp exampleConfig.js local.js

Set up init.d

wget https://gist.github.com/raw/1071989/c81cb3e25c3a8ed5426572474344e3f8eb0c6e53/statsd.init.sh
mv statsd.init.sh /etc/init.d/statsd
chmod 0755 /etc/init.d/statsd
chkconfig --add statsd
