Graphite

Can't start carbon-cache.py

Asked by Sam Weber

Here are all the steps I've taken in attempting to install Graphite:

Fresh install of Ubuntu 12.04.4

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install git

git clone https://github.com/graphite-project/graphite-web.git
git clone https://github.com/graphite-project/carbon.git
git clone https://github.com/graphite-project/whisper.git
git clone https://github.com/graphite-project/ceres.git

cd graphite-web/
sudo python setup.py install
cd ..

cd carbon
sudo python setup.py install
cd ..

cd whisper
sudo python setup.py install
cd ..

cd ceres
sudo python setup.py install

cd /opt/graphite/conf
sudo cp carbon.conf.example carbon.conf
sudo cp storage-schemas.conf.example storage-schemas.conf

$ /opt/graphite/bin/carbon-cache.py start
Traceback (most recent call last):
  File "/opt/graphite/bin/carbon-cache.py", line 28, in <module>
    from carbon.util import run_twistd_plugin
ImportError: No module named carbon.util

---------------------

I tried a variety of things in trying to work this issue:

Did the same steps starting with a 14.04 VM. Same problem.

Google searches: "No module named carbon.util", astonishingly, gets no hits.

Installed pip, python build headers, build-essential to get this: "sudo pip install 'Twisted<12.0'" to work. After successful installation, same error.

There appears to be a bug in master. You probably want to use 0.9.12 or install from the 0.9.x branch.

Tried the 0.9.x branch using the following procedure:

cd /opt
sudo rm -rf graphite

Went to the graphite-web, whisper, and carbon directories and executed "git checkout 0.9.x" (ceres has no 0.9.x branch).

Rebuilt in each directory with "sudo python setup.py install"

In conf directory, copied carbon.conf.example and storage-schemas.conf.example to .conf equivalents.

$ sudo /opt/graphite/bin/carbon-cache.py start

Thanks. carbon-cache.py now starts up. On to the remaining setup tasks.
