• 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 ​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

  data_source "${HOSTNAME_1}" ${HOSTNAME_1}:8649
  data_source "${HOSTNAME_2}" ${HOSTNAME_2}:8649
  data_source "${HOSTNAME_3}" ${HOSTNAME_3}:8649
  trusted_hosts 127.0.0.1 ${HOSTNAME_1} ${HOSTNAME_2} ${HOSTNAME_3}
  

• /etc/ganglia/gmond.conf

  gmond.conf

  • 看完這張圖才恍然大悟，我先前的設定錯了，不該把 gmond 指到 gmond 去。
