 * 準備 ICAS, Crawlzilla, f-motif Demo VM

== Ganglia ==

 * Ganglia 設定檔參考 - Ubuntu karmic (9.04) 以後是 3.1.2-2 版本，且有 [http://packages.ubuntu.com/ganglia-webfrontend ganglia-webfrontend 套件]，設定方式比較簡單。
{{{
#### Server ####
~$ sudo apt-get install gmetad ganglia-webfrontend ganglia-monitor
#### Client ####
~$ sudo apt-get install ganglia-monitor
}}}
 * 把 ganglia-webfrontend 的 apache 設定檔連結到 apache2 的目錄
{{{
~$ cd /etc/apache2/conf.d
/etc/apache2/conf.d$ sudo ln -s ../../ganglia-webfrontend/apache.conf ganglia-webfrontend
/etc/apache2/conf.d$ sudo apache2ctl restart
}}}
 * /etc/ganglia/gmetad.conf - 自行取代掉 ${HOSTNAME_*} 內容
