How to install Graphite as a user on CentOS 5.5 (with neither internet access and root account)

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

Graphite is a Scalable Realtime Graphing (http://graphite.wikidot.com/)

This script is based on two excellent tutorials:

http://community.webfaction.com/questions/10038/how-to-install-pycairo-in-python27-thanks

https://gist.github.com/jgeurts/3112065

My scenario:

- no internet access

- only user account, no root account

- gcc and make installed

- some libraries missing

- no development packages for installed libraries

#

Goals:

- installation directory is $HOME/graphite-install

- install libraries to $HOME

- install Graphite and stuff to $HOME/graphite

#

If you see wget here - wget it to your local machine and upload to remote CentOS.

You must have gcc and make installed. You can't go on without it.

Check it with:

rpm -qa | grep gcc

---- 1. Environment setup ----

Set up these variables. Some of these directories don't exist yet. They will be created as you go on.

You can put these variables to your .bashrc.

export CFLAGS="-I$HOME/include -I$HOME/include/python2.7"
export CPPFLAGS="-I$HOME/include -I$HOME/include/python2.7"
export PKG_CONFIG_PATH="$HOME/lib/pkgconfig"
export LDFLAGS="-L$HOME/lib -L$HOME/lib/python2.7"
export LD_LIBRARY_PATH="$HOME/lib:$HOME/lib/python2.7:$HOME/lib/python2.7/site-packages/cairo"
export PYTHONPATH="$HOME/lib/python:$HOME/lib/python2.7/site-packages:$HOME/.local/bin/usr/local/lib/python2.7/site-packages"
export PATH="$HOME/.local/bin:$PATH"

---- 2. Libraries ----

These libraries are required by Graphite. You need to compile them, because other libraries and python modules

need their headers. They are installed to $HOME/lib and headers are placed in $HOME/include.

cd $HOME/graphite-install

wget http://zlib.net/zlib-1.2.8.tar.gz
wget ftp://ftp.simplesystems.org/pub/libpng/png/src/libpng-1.6.2.tar.gz
wget http://www.sqlite.org/2013/sqlite-autoconf-3071700.tar.gz

tar zxf zlib-1.2.8.tar.gz
tar zxf libpng-1.6.2.tar.gz
tar zxf sqlite-autoconf-3071700.tar.gz

cd zlib-1.2.8
./configure --prefix=$HOME
make
make install

cd ../libpng-1.6.2
./configure --prefix=$HOME
make
make install

cd ../sqlite-autoconf-3071700.tar.gz
./configure --prefix=$HOME
make
make install

---- 3. Python 2.7.5 ----

Python installed by default in CentOS may miss some native modules compiled. You need to recompile.

cd $HOME/graphite-install
wget http://www.python.org/ftp/python/2.7.5/Python-2.7.5.tgz

tar zxf Python-2.7.5.tgz
cd Python-2.7.5

enable-shared is crucial here

./configure --enable-shared --prefix=$HOME
make

Check output for this line:

Python build finished, but the necessary bits to build these modules were not found:

Make sure that _zlib and _sqlite3 IS NOT on that list. Otherwise you miss dependencies or you had errors before.

make install

Now you can have two Python installations in system. I use ~/bin/python everywhere from now on to use my version.

---- 4. Cairo ----

Cairo has some dependencies to fulfill.

cd $HOME/graphite-install
wget http://cairographics.org/releases/pixman-0.26.2.tar.gz
wget ftp://sourceware.org/pub/libffi/libffi-3.0.11.tar.gz
wget http://ftp.gnome.org/pub/GNOME/sources/glib/2.31/glib-2.31.22.tar.xz
wget http://cairographics.org/releases/cairo-1.12.2.tar.xz
wget http://cairographics.org/releases/py2cairo-1.10.0.tar.bz2

tar xzf pixman-0.26.2.tar.gz
tar xzf libffi-3.0.11.tar.gz

My system didn't have unxz so I had to download and repack to zip.

unzip glib-2.31.22.zip

unzip cairo-1.12.2.zip

unxz glib-2.31.22.tar.xz
unxz cairo-1.12.2.tar.xz
tar xjf py2cairo-1.10.0.tar.bz2

cd libffi-3.0.11
./configure --prefix=$HOME
make
make install

cd ../glib-2.31.22
./configure --prefix=$HOME
make
make install

cd ../pixman-0.26.2
./configure --prefix=$HOME
make
make install

cd ../cairo-1.12.2
./configure --prefix=$HOME
make
make install

cd ../py2cairo-1.10.0
~/bin/python ./waf configure --prefix=$HOME
~/bin/python ./waf build
~/bin/python ./waf install

Check if cairo is properly installed:

~/bin/python -c 'import cairo; print cairo.version'

You should see cairo version number.

If there is an import error, there is something wrong with your PYTHONPATH.

---- 5. Django and modules ----

Remember that it is all installed in user directory.

cd $HOME/graphite-install
wget https://django-tagging.googlecode.com/files/django-tagging-0.3.1.tar.gz
wget https://www.djangoproject.com/m/releases/1.5/Django-1.5.1.tar.gz
wget https://pypi.python.org/packages/source/z/zope.interface/zope.interface-4.0.5.zip#md5=caf26025ae1b02da124a58340e423dfe
wget http://twistedmatrix.com/Releases/Twisted/11.1/Twisted-11.1.0.tar.bz2

unzip zope.interface-4.0.5.zip
tar zxf django-tagging-0.3.1.tar.gz
tar zxf Django-1.5.1.tar.gz
tar jxf Twisted-11.1.0.tar.bz2

cd zope.interface-4.0.5
~/bin/python setup.py install --user

cd ../Django-1.5.1
~/bin/python setup.py install --user

cd ../django-tagging-0.3.1
~/bin/python setup.py install --user

cd ../Twisted-11.1.0
~/bin/python setup.py install --user

---- 6. Graphite ----

Remember that it is all installed into $HOME/graphite directory!

cd $HOME/graphite-install
wget https://launchpad.net/graphite/0.9/0.9.10/+download/graphite-web-0.9.10.tar.gz
wget https://launchpad.net/graphite/0.9/0.9.10/+download/carbon-0.9.10.tar.gz
wget https://launchpad.net/graphite/0.9/0.9.10/+download/whisper-0.9.10.tar.gz
tar -zxvf graphite-web-0.9.10.tar.gz
tar -zxvf carbon-0.9.10.tar.gz
tar -zxvf whisper-0.9.10.tar.gz

cd whisper-0.9.10
~/bin/python setup.py install --home=$HOME/graphite

cd ../carbon-0.9.10
~/bin/python setup.py install --home=$HOME/graphite

cd ../graphite-web-0.9.10

You're almost there. Check if all dependencies are met:

~/bin/python check-dependencies.py

There should be no fatal errors, only warnings for optional modules.

~/bin/python setup.py install --home=$HOME/graphite

---- 7. Configuration ----

cd $HOME/graphite/conf

Copy example configurations

cp carbon.conf.example carbon.conf
cp storage-schemas.conf.example storage-schemas.conf
vim storage-schemas.conf

You should really read document on how to configure your storage. It is a quick read:

http://graphite.wikidot.com/getting-your-data-into-graphite

Configure it the way you need.

cd $HOME/graphite/lib/python/graphite
cp local_settings.py.example local_settings.py

vim local_settings.py

This file is crucial:

Line around 13: setup your TIME_ZONE from this list: http://stackoverflow.com/questions/13866926/python-pytz-list-of-timezones

Line around 23: DEBUG = True

Line around 24: append ALLOWED_HOSTS = ["*"]

Lines around 46-54: change paths from /opt/graphite to your explicit graphite installation dir,

for example /home/you/graphite. $HOME doesn't work here!

Uncomment lines 141-150 (starting with DATABASES) and update NAME with full explicit database path. $HOME doesn't work here!

Create new database for Graphite web application

~/bin/python manage.py syncdb

Start carbon deamon

cd $HOME/graphite
~/bin/python carbon-cache.py status
~/bin/python carbon-cache.py start

I run development graphite server in a screen, since I cannot expose it via httpd.

screen

In screen

~/bin/python manage.py runserver

Detach with Control-A, Control-D (attach again with screen -r next time)

Check if it works, you should see <title>Graphite Browser</title>

curl localhost:8000

You can run some example client to send some stats.

You can adjust example-client.py delay value for more/less stats.

cd $HOME/graphite/examples
~/bin/python example-client.py

Done!

Easy as pie :)
