How to install collectd & graphite on Ubuntu and CentOS

This post is a direct approach to install collectd & graphite on Ubuntu, by direct I mean using the available repositories:

Requeriments

- Ubuntu 13.10 installed and configured with standard repositories
- CentOS 6.3 + EPEL repository configured
- Login as root

Ubuntu guide

(i) Install collectd daemon:

# apt-get install collectd

(here you may modify the collectd config file and select the metrics to harvest)

(ii) Install apache2 & graphite, disable default site and enable graphite site:

# apt-get install apache2 libapache2-mod-wsgi
# apt-get install graphite-carbon graphite-web

(iii) Config graphite site, disable default site and enable graphite site:

# cd /etc/apache2/sites-available/
# ln -s /usr/share/graphite-web/apache2-graphite.conf
# a2dissite 000-default
# a2ensite apache2-graphite

(iv) Initial graphite DB creation:

# cd /usr/share/pyshared/graphite
# python manage.py syncdb

(v) Configure carbon cache:

# nano /etc/default/graphite-carbon

(and change flag to true)

CARBON_CACHE_ENABLED=true

(vi) Setup carbon-cache to autostart, then start it:

# chkconfig --levels 235 carbon-cache on
# /etc/init.d/carbon-cache start

(vii) Setup collectd to autostart:

# chkconfig --levels 235 collectd on
# /etc/init.d/collectd start

(viii) Restart apache2:

# service apache2 restart

CentOS guide

(i) Install & config collectd daemon:

# yum install collectd pyhton-bucky httpd
# cp /etc/collectd.conf /etc/collectd.conf.org

(here you may modify the collectd config file and select the sts to harvest)

(ii) Install apache2 & graphite, config apache to autostart:

# yum install graphite-web python-carbon
# chkconfig --levels 235 httpd on
# /etc/init.d/httpd start

(iii) Initial graphite DB creation:

# cd /usr/lib/python2.6/site-packages/graphite
# python manage.py syncdb

(iv) configure carbon cache:

# chkconfig --levels 235 carbon-cache on
# /etc/init.d/carbon-cache start

(v) restart apache:

# /etc/init.d/httpd restart

(vii) Setup collectd to autostart:

# chkconfig --levels 235 collectd on
# /etc/init.d/collectd start


At this point you are already collecting metrics!
Enjoy it!
