**1.安装JDK**

**2.安装scala 2.9.3**

Spark 0.7.2 依赖 Scala 2.9.3, 我们必须要安装Scala 2.9.3.

下载 scala-2.9.3.tgz 并 保存到home目录(已经在sg206上）.  
$ tar -zxf scala-2.9.3.tgz  
$ sudo mv scala-2.9.3 /usr/lib  
$ sudo vim /etc/profile  
\# add the following lines at the end  
export SCALA\_HOME=/usr/lib/scala-2.9.3  
export PATH=$PATH:$SCALA\_HOME/bin  
\# save and exit vim  
\#make the bash profile take effect immediately  
source /etc/profile  
\# test  
$ scala -version

**3.building spark**

cd /home

tar -zxf spark-0.7.3-sources.gz

cd spark-0.7.3

sbt/sbt package  (需要git环境  yum install git）

**4.配置文件**

spark-env.sh

\#\#\#\#\#\#\#\#\#\#\#\#

export SCALA\_HOME=/usr/lib/scala-2.9.3  
export SPARK\_MASTER\_IP=172.16.48.202  
export SPARK\_WORKER\_MEMORY=10G

\#\#\#\#\#\#\#\#\#\#\#\#\#

slaves

将从节点IP添加至slaves配置文件

**5.启动和停止**

bin/start-master.sh - Starts a master instance on the machine the script is executed on.  
bin/start-slaves.sh - Starts a slave instance on each machine specified in the conf/slaves file.  
bin/start-all.sh - Starts both a master and a number of slaves as described above.  
bin/stop-master.sh - Stops the master that was started via the bin/start-master.sh script.  
bin/stop-slaves.sh - Stops the slave instances that were started via bin/start-slaves.sh.  
bin/stop-all.sh - Stops both the master and the slaves as described above.

6. 浏览master的web UI(默认[http://localhost:8080][http_localhost_8080]). 这是你应该可以看到所有的word节点，以及他们的CPU个数和内存等信息。
