Gentoo x86
Graphite 0.9.9
Python 2.7.2
Apache 2.2.22
一. 關于Graphite
1. Graphite，相當年輕的企業級開源監控工具，可以用于采集、統計多個伺服器的實時狀态，包括使用者請求、memcached緩存命中、rabbitMQ消息伺服器狀态，以及基本的系統負載等。
2. 采用Python編寫，Django架構，sqlite資料庫存儲，自有簡單文本協定通訊，繪圖功能強大。
3. 事實上，嚴格地說，Graphite隻是一個根據資料繪圖的工具，資料收集通常由第三方工具或插件完成，自帶的是carbon，可根據其協定選用别的資料源供其繪圖。
二. 安裝流程
1. 更改Gentoo的python版本到2.7
# eselect python list
Available Python interpreters:
[1] python2.7
[2] python3.2 *
# eselect python set 1
2. 安裝軟體包，包括依賴包和graphite本身
# emerge apache apache-wsgi pip pysqlite
# pip install django django-tagging twisted cairo whisper carbon graphite-web
3. 初始化配置檔案
# cd /opt/graphite/conf
# cp carbon.conf.example carbon.conf
# cp storage-schemas.conf.example storage-schemas.conf
# cp graphite.wsgi.example graphite.wsgi
# cd /opt/graphite/webapp/graphite
# cp local_settings.py.example local_settings.py
4. 修改httpd.config添加wsgi子產品
在LoadModule的部分添加一行：
LoadModule wsgi_module modules/mod_wsgi.so
5. 修改預設的虛拟主機配置檔案
# cd /etc/apache2/vhosts.d
# mv 00_default_vhost.conf 00_default_vhost.conf.bak
# mkdir -p /etc/apache2/wsgi
# vim 00_default_vhost.conf
Listen 80
WSGISocketPrefix /etc/apache2/wsgi/
<VirtualHost *:80>
ServerName graphite
DocumentRoot “/opt/graphite/webapp”
ErrorLog /opt/graphite/storage/log/webapp/error.log
CustomLog /opt/graphite/storage/log/webapp/access.log common
WSGIDaemonProcess graphite processes=5 threads=5 display-name=’%{GROUP}’ inactivity-timeout=120
WSGIProcessGroup graphite
WSGIApplicationGroup %{GLOBAL}
WSGIImportScript /opt/graphite/conf/graphite.wsgi process-group=graphite application-group=%{GLOBAL}
WSGIScriptAlias / /opt/graphite/conf/graphite.wsgi
Alias /content/ /opt/graphite/webapp/content/
<Location “/content/”>
SetHandler None
Order Deny,Allow
</Location>
Alias /media/ “/usr/lib/python2.7/site-packages/django/contrib/admin/media/”
<Location “/media/”>
SetHandler None
Order Deny,allow
</Location>
<Directory /opt/graphite/conf/>
Order deny,allow
Allow from all
</Directory>
</VirtualHost>
上面的配置檔案内容修改自graphite源碼包内的預設配置檔案，修改部分已經标出。
6. 生成資料庫并更改資料庫目錄權限
# cd /opt/graphite/webapp/graphite
# python manage.py syncdb
# chown -R apache:apache /opt/graphite/storage
7. 啟動相關程式
carbon：
/opt/graphite/bin/carbon-cache.py start
apache2：
/etc/init.d/apache2 start
至此Graphite安裝完畢。浏覽器中的效果如圖所示，可以對資料源、圖表的風格等分别自定義，也可以實作自動重新整理、對圖表進行聚合等等，功能豐富完備。
