Install Graphite in CentOS 5.5

Install Graphite in CentOS 5.5

1. Summary of system information

[Root @ cc-monitor conf] # uname-

Linux cc-monitor 2.6.18-194.32.1.el5 #1 SMP Wed Jan 5 17:52:25 EST 2011 x86_64 x86_64 x86_64 GNU/Linux

 

[Root @ cc-monitor conf] # python-V

Python 2.4.3

 

[Root @ cc-monitor conf] # getenforce

Disabled
 

 

2. Install the Graphite dependency package

 

Add additional sources

In addition to CentOS source base, updates, and extra, add two sources: epel and rpmforge.

# Install the epel Source

Wget http://mirrors.sohu.com/Fedora-epel/5/i386/epel-release-5-4.noarch.rpm

Yum install epel-release-5-4.noarch.rpm

# Installing the rpmforge Source

Wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm

Yum install rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm

 

Install dependency packages

There are quite a few dependency packages, so try to get it done once.

Yum-y install bitmap-fonts Django pycairo python-devel python-ldap python-memcached mod_wsgi python-sqlite2 glibc-devel gcc-c ++ git openssl-devel python-zope-interface httpd memcached python-hashlib django-tagging python-twisted python-simplejson

 

Here is a simple description:

Cairo is a drawing library of graphite and a required software.

Bitmap-fonts are also required. Otherwise, the image may not be displayed properly.

Python-twisted must install the python-twisted-core-8.2.0-1.el5.rf of the rpmforge source, which is why the rpmforge source is added.

Mod_wsgi is an apache module.
 

 

3. Install the Graphite component

 

The Graphite component consists of carbon, whisper, and graphite-web.

:

Https://github.com/graphite-project/graphite-web/downloads

Https://github.com/graphite-project/whisper/downloads

Https://github.com/graphite-project/carbon/downloads

# Install graphite-web

Tar zxvf graphite-web-0.9.10.tar.gz

Cd graphite-web-0.9.10

Python setup. py install

Cd ..

# Install whisper

Tar zxvf whisper-0.9.10.tar.gz

Cd whisper-0.9.10

Python setup. py install

Cd ..

# Install carbon

Tar zxvf carbon-0.9.10.tar.gz

Cd carbon-0.9.10

Python setup. py install

 

 

 

4. Configure the apache service

 

Create the virtual host configuration of Graphite:/etc/httpd/conf. d/graphite. conf. The creation method is as follows:

Cat>/etc/httpd/conf. d/graphite. conf

Listen 8080.

 

# You may need to manually edit this file to fit your needs.

# This configuration assumes the default installation prefix

# Of/opt/graphite/, if you installed graphite somewhere else

# You will need to change all the occurances of/opt/graphite/

# In this file to your chosen install location.

<VirtualHost *: 8080>

ServerName graphite

DocumentRoot "/opt/graphite/webapp"

 

# I 've found that an equal number of processes & threads tends

# To show the best performance for Graphite (ymmv ).

WSGIDaemonProcess graphite processes = 5 threads = 5 display-name = '% {GROUP}' inactivity-timeout = 120

WSGIProcessGroup graphite

 

# You will need to create this file! There is a graphite. wsgi. example

# File in this directory that you can safely use, just copy it to graphite. wgsi

WSGIScriptAlias // opt/graphite/conf/graphite. wsgi

 

Alias/content // opt/graphite/webapp/content/

<Location "/content/">

SetHandler None

</Location>

 

# NOTE: In order for the django admin site media to work you

# Must change @ DJANGO_ROOT @ to be the path to your django

# Installation, which is probably something like:

#/Usr/lib/python2.6/site-packages/django

Alias/media/"/usr/lib/python2.4/site-packages/django/contrib/admin/media /"

<Location "/media/">

SetHandler None

</Location>

 

# The graphite. wsgi file has to be accessible by apache. It won't

# Be visible to clients because of the DocumentRoot though.

<Directory/opt/graphite/conf/>

Order deny, allow

Allow from all

</Directory>

 

</VirtualHost>

 

Configure the mod_wsgi Module

Add the following two lines to the/etc/httpd/conf. d/wsgi. conf file:

LoadModule wsgi_module modules/mod_wsgi.so

WSGISocketPrefix/var/run/wsgi

 

 

 

5. Configure Graphite

 

Run the following command to create a configuration file

Cd/opt/graphite/conf/

For I in graphite. wsgi carbon. conf storage-schemas.conf storage-aggregation.conf; do cp $ I. example $ I; done

Cd/opt/graphite/webapp/graphite/

Cp local_settings.py.example local_settings.py

 

Run the following command to create a database:

Cd/opt/graphite/webapp/graphite/

Python manage. py syncdb

Chown-R apache: apache/opt/graphite/

 

 

 

 

6. Start services and programs

 

Service httpd start

/Opt/graphite/bin/carbon-cache.py start

The installation is complete. Use http: // ip: 8080 in the browser and use the ip address of the host where graphite is installed. If you can access it, you can tell you that CentOS 5 has successfully installed Graphite.
 

 

7. Install node-js and statsd

 

# Install python2.6 first

Yum install bzip2 * glibc-devel

Cd Python-2.6.8

Make clean

./Configure

Make

Make install

Ln-s/usr/local/bin/python/usr/bin/python

 

# Install node-js again

Web http://nodejs.org/dist/node-v0.4.8.tar.gz

Cd node-v0.8.7

./Configure

Make

Make install

 

# Verify whether the installation is successful

[Root @ cc-monitor statsd-2.0.1] # node-v

V0.8.7

 

# Install statsd

Git clone http://github.com/etsy/statsd.git

Cp-R statsd/opt/graphite/

 

 

 

# Create/opt/graphite/statsd/local. js

[Root @ cc-monitor statsd] # cat local. js

{

GraphitePort: 2003

, GraphiteHost: "localhost"

, Port: 8124

}

 

# Start nodejs/statsd

Cd/opt/graphite/statsd

Nohup/usr/local/bin/node stats. js local. js &
