- 根據 Orbited 的相依說明,我們會需要這幾個套件
- python2.5 - An interactive high-level object-oriented language (version 2.5)
- [註一] 用 Python 2.4 在執行 orbited 時會遇到一些 Runtime Error~
- [註二] 由於安裝之後,Etch 預設還是用 Python2.4,很難改變預設 Runtime,因此網路上建議直接用 tarball 安裝。另一個解法就是升級到 lenny。
~$ echo "deb http://free.nchc.org.tw/debian/ lenny main contrib non-free" > /tmp/lenny.list ~$ sudo mv /tmp/lenny.list /etc/apt/sources.list.d/ ~$ sudo rm /etc/apt/sources.list ~$ sudo apt-get update ~$ sudo apt-get -t lenny -y upgrade ~$ sudo apt-get -t lenny -y dist-upgrade
- python-setuptools - Python Distutils Enhancements
- python-twisted - Event-based framework for internet applications (transitional package)
- python-simplejson - Simple, fast, extensible JSON encoder/decoder for Python
- python2.5 - An interactive high-level object-oriented language (version 2.5)
- 安裝 Orbited 相關套件
~$ sudo apt-get install python-setuptools python-twisted python-simplejson ~$ wget http://pypi.python.org/packages/source/o/orbited/orbited-0.7.0.tar.gz ~$ tar zxvf orbited-0.7.0.tar.gz ~$ sudo easy_install orbited-0.7.0 ~$ sudo cp orbited-0.7.0/orbited.cfg /etc/
- 測試 Orbited
~$ python Python 2.5.2 (r252:60911, Sep 29 2008, 21:15:13) [GCC 4.3.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import orbited >>> [Ctrl+D]
- 如果沒有錯誤訊息就可以繼續跑測試了。參考Scalable Real-Time Web Architecture, Part 2: A Live Graph with Orbited, MorbidQ, and js.io,我們在 Lenny 的環境下,成功重現這個範例。
~$ sudo easy_install stompservice ~$ wget http://cometdaily.com/wp-content/uploads/2008/10/graph_demo.tgz ~$ tar zxvf graph_demo.tgz ~$ cd graph_demo/ ~/graph_demo$ for i in `find . -type f`; do sed "s#localhost#${NEW_IP_ADDRESS}#g" $i > $i.bak; mv $i.bak $i; done ~/graph_demo$ orbited --config graph.cfg 10/30/08 16:08:02:525 INFO orbited.start proxy protocol active 10/30/08 16:08:02:525 INFO orbited.start Listening http@9000 10/30/08 16:08:02:527 INFO orbited.start Listening stomp@61613
- 連線到 http://${NEW_IP_ADDRESS}:9000/graph ,並在另一個 console 下執行 data_producer.py,就會看到圖表一直在變化。
