參考Hadoop官網之Single Node Setup，您可以透過一行指令碼簡單啟動Hadoop服務...
啟動Standalne模式，並直接執行預設範例(需要的話，可以直接下載Script做修改)：
curl -sS -k https://raw.github.com/micloud/installer/master/standard64-hadoop1.0.4/init-hadoop-standalone.sh | sh
啟動Pseudo-Distributed Operation模式：
curl -sS -k https://raw.github.com/micloud/installer/master/standard64-hadoop1.0.4/init-hadoop-pseudo-distributed.sh | sh
Standalone模式屬於範例的執行測試，在這邊就不執行測試...
下面顯示Pseudo-Distributed Operation模式...
[root@bddbe1f4 /usr/local/hadoop]# curl -sS -k https://raw.github.com/micloud/installer/master/standard64-hadoop1.0.4/init-hadoop-pseudo-distributed.sh | sh
===============Pseudo-Distributed Operation===============
Create config files ...
Edit .bashrc ...
===============Setup passphraseless ssh===============
