CentOS 5.5 安装Graphite

CentOS 5.5 安装Graphite
1.系统信息汇总[root@cc-monitor conf]# uname -aLinux 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 -VPython 2.4.3
[root@cc-monitor conf]# getenforceDisabled

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-epel/5/i386/epel-release-5-4.noarch.rpmyum install epel-release-5-4.noarch.rpm# 安装rpmforge源wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpmyum 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/downloadshttps://github.com/graphite-project/whisper/downloadshttps://github.com/graphite-project/carbon/downloads# install graphite-webtar zxvf graphite-web-0.9.10.tar.gzcd graphite-web-0.9.10python setup.py installcd ..# install whispertar zxvf whisper-0.9.10.tar.gzcd whisper-0.9.10python setup.py installcd ..# install carbontar zxvf carbon-0.9.10.tar.gzcd carbon-0.9.10python 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.confListen 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.soWSGISocketPrefix /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; donecd /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 syncdbchown -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python2.6yum install bzip2* glibc-develcd Python-2.6.8make clean./configuremakemake installln -s /usr/local/bin/python /usr/bin/python
#再安装node-jswet http://nodejs.org/dist/node-v0.4.8.tar.gzcd node-v0.8.7./configuremakemake install
#验证安装是否成功[root@cc-monitor statsd-2.0.1]# node -vv0.8.7
#安装statsdgit clone http://github.com/etsy/statsd.gitcp -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/statsdcd /opt/graphite/statsdnohup /usr/local/bin/node stats.js local.js &更多CentOS相关信息见CentOS 专题页面 http://www.linuxidc.com/topicnews.aspx？tid=14route命令详解与使用实例Linux变更shell相关资讯 Graphite
