This gist contains everything you need to install StatsD and Graphite on CentOS 6.3. Unless I forgot something. If I did, shoot a reminder email to noah at one more bug dot com. tl;dr: womm, ymmv, yolo.
I (mostly) followed the steps shown in the EZUnix wiki
And I also referred back to this gist by Michael Grace

You don't actually need to disable selinux (or you would have already done it by default in your installation)

chcon -R -t httpd_sys_content_t /opt/graphite/storage/
Git clones now need to be changed to https URLs. I received RPC errors otherwise.
This gave me Twisted 13.2 which is incompatible with carbon-cache. Had to downgrade to Twisted 12.
Error:
Traceback (most recent call last):
File "./bin/carbon-cache.py", line 28, in <module>
from carbon.util import run_twistd_plugin
File "/opt/graphite/lib/carbon/util.py", line 21, in <module>
from twisted.scripts._twistd_unix import daemonize
ImportError: cannot import name daemonize
Solution:
pip install 'Twisted<12.0'

Line 80 Should read
service httpd start
Lines 84 and 95 should use https. Trying to clone from an http url won't work.

I followed your wonderful script, but chown -R apache:apache /opt/graphite/storage/ was not enough getting errors below. I had to chown -R apache:apache /opt/graphite/ Thank you for your scripts!
