CentOS 5.5 安装Graphite

1.系统信息汇总

[iyunv@cc-monitor conf]# uname -a 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 [iyunv@cc-monitor conf]# python -V Python 2.4.3 [iyunv@cc-monitor conf]# getenforce Disabled

2.安装Graphite依赖包

添加额外的源 除了CentOS源base、updates、extra之外，再添加两个源：epel和rpmforge。 # 安装epel源 wget  http://mirrors.sohu.com/fedora-e ... ease-5-4.noarch.rpm yum install epel-release-5-4.noarch.rpm # 安装rpmforge源 wget  http://pkgs.repoforge.org/rpmfor ... 2.el5.rf.x86_64.rpm yum install rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm 安装依赖包 依赖包相当多，争取一次搞定 yum -y install bitmap bitmap-fonts Django pycairo python-devel  python-ldap python-memcached mod_wsgi python-sqlite2 glibc-devel gcc gcc-c++  git openssl-devel python-zope-interface httpd memcached python-hashlib   django-tagging python-twisted python-simplejson 这里还是做一下简单说明： cairo是graphite的绘图库，是必须的软件。 bitmap-fonts字体也是需要的，否则可能图形显示不正常 python-twisted必须安装rpmforge源的python-twisted-core-8.2.0-1.el5.rf，这也是为什么添加rpmforge源的原因。 mod_wsgi是apache的模块

3.安装Graphite组件

Graphite组件包括三个部分：carbon、whisper和graphite-web 下载地址： 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.配置apache服务

创建 Graphite 的虚拟主机配置：/etc/httpd/conf.d/graphite.conf，创建方法如下： 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> 配置mod_wsgi模块 在  /etc/httpd/conf.d/wsgi.conf文件中添加以下两行： LoadModule wsgi_module  modules/mod_wsgi.so WSGISocketPrefix /var/run/wsgi

5.配置Graphite

运行以下命令创建配置文件 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 运行以下命令创建数据库： cd /opt/graphite/webapp/graphite/ python manage.py syncdb chown -R apache:apache /opt/graphite/

6.启动服务和程序

service httpd start /opt/graphite/bin/carbon-cache.py start 安装已经完成。在浏览器中使用http://ip:8080，使用安装graphite的主机的ip代替。可以访问即可以肯定的告诉你CentOS 5安装Graphite成功了

7.安装node-js和statsd

#先安装python2.6 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 #再安装node-js wet  http://nodejs.org/dist/node-v0.4.8.tar.gz cd node-v0.8.7 ./configure make make install #验证安装是否成功 [iyunv@cc-monitor statsd-2.0.1]# node -v v0.8.7 #安装statsd git clone http://github.com/etsy/statsd.git cp -R statsd /opt/graphite/ #Create /opt/graphite/statsd/local.js [iyunv@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 &
