Running Carbon and StatsD as Daemon on Centos init.d file for statsd and carbon on Centos

README.markdown

Forged by Maanas Royy from command logs

#Centos 6.3 x86_64

Install the required dependencies

yum install -y git gcc gcc-c++ zlib-devel curl curl-devel openssl

Install node

git clone git://github.com/joyent/node.git
cd node
./configure
make
make install

Make sym link to add node and npm in path

    ln -s /opt/node/bin/node /usr/local/bin
ln -s /opt/node/bin/npm /usr/loca/bin/npm

--- Install Graphite dependencies ---

yum install -y pycairo mod_python Django python-ldap python-memcached python-sqlite2 \
			   bitmap bitmap-fonts python-devel python-crypto pyOpenSSL zope

--- Install Python setup tools & pip ---

    yum install python-setuptools
    easy_install pip

--- Install Whisper - Graphite's DB system ---

wget "http://launchpad.net/graphite/1.0/0.9.7/+download/whisper-0.9.7-1.noarch.rpm"
rpm -Uvh whisper-0.9.7-1.noarch.rpm
rm -rf whisper*.rpm

-- Install Graphite back-end ---

    pip install whisper
    pip install carbon
    pip install twisted
    pip install django==1.3
    pip install graphite-webapp

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 Nginx user/group

chown -R www-data:nobody /opt/graphite/storage/

Config graphite /opt/graphite/conf

Set up init.d

wget https://raw.github.com/gist/3891354/32b8da693933ccc5b04445c13ec280a622f61400/carbon.init.sh
mv carbon.init.sh /etc/init.d/carbon
chmod 0755 /etc/init.d/carbon
chkconfig --add carbon

--- 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 localConfig.js

Set up init.d

https://raw.github.com/gist/3891354/c81cb3e25c3a8ed5426572474344e3f8eb0c6e53/statsd.init.sh
mv statsd.init.sh /etc/init.d/statsd
chmod 0755 /etc/init.d/statsd
chkconfig --add statsd
