一、安装vmware虚拟机

二、在虚拟机上安装ubuntu12.04操作系统

三、安装jdk1.8.0_25

http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

注意：下载操作系统对应版本的jdk

解压：

tar -xzvf jdk-8u25-linux-i586.tar.gz

配置环境变量参数

sudo gedit /etc/profile

export JAVA_HOME=/home/yuanqin/Downloads/jdk1.8.0_25   (此地址为jdk安装路径，每个人根据自己jdk的安装地址进行配置)
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

验证是否安装成功：java -version

手动设置系统默认jdk:

sudo update-alternatives --install /usr/bin/java java /home/yuanqin/Downloads/jdk1.8.0_25/bin/java 300

sudo update-alternatives --install /usr/bin/javac javac /home/yuanqin/Downloads/jdk1.8.0_25/bin/javac 300

sudo update-alternatives --config java

四、安装ssh并设置免密码登录

sudo apt-get install ssh

配置为可以免密码登录本机，首先查看yuanqin用户下是否有.ssh文件，没有的话自己创建一个  

查看代码：ls -a /home/yuanqin

配置免密码登录的代码： ssh-keygen -t dsa

cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

验证是否安装成功：ssh -version    ; ssh localhost

五、安装hadoop-1.2.1

http://mirrors.cnnic.cn/apache/hadoop/common/hadoop-1.2.1/

解压：

tar -xzvf hadoop-1.2.1.tar.gz
配置jdk安装位置：
sudo gedit /home/yuanqin/Downloads/hadoop-1.2.1/conf/hadoop-env.sh
值：export JAVA_HOME=/home/yuanqin/Downloads/jdk1.8.0-25

配置core-site.xml文件：

sudo gedit /home/yuanqin/Downloads/hadoop-1.2.1/conf/core-site.xml
值：<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000</value>
</property>
</configuration>

配置hdfs-site.xml文件：

sudo gedit /home/yuanqin/Downloads/hadoop-1.2.1/conf/hdfs-site.xml
值：<configuration>
<property>
<name>dfs.replication</name>
<value>3</value>
</property>
</configuration>


配置mapre-site.xml文件：

sudo gedit /home/yuanqin/Downloads/hadoop-1.2.1/conf/mapre-site.xml
值：<configuration>
<property>
<name>mapred.job.tracker</name>
<value>localhost:9001</value>
</property>
</configuration>
接下来先格式化文件系统hdfs,进入hadoop文件夹，输入：bin/hadoop namenode -format
启动hadoop: bin/start-all.sh(bin/start-dfs.sh 启动hdfs;    bin/start-mapred.sh 启动mapreduce)
验证hadoop是否安装成功；

在浏览器分别输入网址：http://localhost:50030  (mapreduce页面)
                   http://localhost:50030  (hdfs页面)

六、安装scala-2.10.3
参考：http://shiyanjun.cn/archives/696.html
  • 下载安装配置Scala
1 wget http://www.scala-lang.org/files/archive/scala-2.10.3.tgz
2 tar xvzf scala-2.10.3.tgz

在~/.bashrc中增加环境变量SCALA_HOME，并使之生效：

1 export SCALA_HOME=/usr/scala/scala-2.10.3
2 export PATH=$PATH:$SCALA_HOME/bin
  • 下载安装配置Spark

我们首先在主节点m1上配置Spark程序，然后将配置好的程序文件复制分发到集群的各个从结点上。下载解压缩：

1 wget http://d3kbcqa49mib13.cloudfront.net/spark-0.9.0-incubating-bin-hadoop1.tgz
2 tar xvzf spark-0.9.0-incubating-bin-hadoop1.tgz

在~/.bashrc中增加环境变量SPARK_HOME，并使之生效：
 

1 export SPARK_HOME=/home/shirdrn/cloud/programs/spark-0.9.0-incubating-bin-hadoop1
2 export PATH=$PATH:$SPARK_HOME/bin 
 

在m1上配置Spark，修改spark-env.sh配置文件：

1 cd /home/shirdrn/cloud/programs/spark-0.9.0-incubating-bin-hadoop1/conf
2 cp spark-env.sh.template spark-env.sh

在该脚本文件中，同时将SCALA_HOME配置为Unix环境下实际指向路径，例如：

1 export SCALA_HOME=/usr/scala/scala-2.10.3

修改conf/slaves文件，将计算节点的主机名添加到该文件，一行一个，例如：

1 s1
2 s2
3 s3

最后，将Spark的程序文件和配置文件拷贝分发到从节点机器上：
 

1 scp -r ~/cloud/programs/spark-0.9.0-incubating-bin-hadoop1 shirdrn@s1:~/cloud/programs/
2 scp -r ~/cloud/programs/spark-0.9.0-incubating-bin-hadoop1 shirdrn@s2:~/cloud/programs/
3 scp -r ~/cloud/programs/spark-0.9.0-incubating-bin-hadoop1 shirdrn@s3:~/cloud/programs/

启动Spark集群

我们会使用HDFS集群上存储的数据作为计算的输入，所以首先要把Hadoop集群安装配置好，并成功启动，我这里使用的是Hadoop 1.2.1版本。启动Spark计算集群非常简单，执行如下命令即可：

1 cd /home/shirdrn/cloud/programs/spark-0.9.0-incubating-bin-hadoop1/
2 sbin/start-all.sh

可以看到，在m1上启动了一个名称为Master的进程，在s1上启动了一个名称为Worker的进程，如下所示，我这里也启动了Hadoop集群：
主节点m1上：

1 54968 SecondaryNameNode
2 55651 Master
3 55087 JobTracker
4 54814 NameNode
5  
6 从节点s1上：
7 33592 Worker
8 33442 TaskTracker
9 33336 DataNode

各个进程是否启动成功，也可以查看日志来诊断，例如：

1 主节点上：
2 tail -100f $SPARK_HOME/logs/spark-shirdrn-org.apache.spark.deploy.master.Master-1-m1.out
3 从节点上：
4 tail -100f $SPARK_HOME/logs/spark-shirdrn-org.apache.spark.deploy.worker.Worker-1-s1.out

Spark集群计算验证

我们使用我的网站的访问日志文件来演示，示例如下：

1 27.159.254.192 - - [21/Feb/2014:11:40:46 +0800] "GET /archives/526.html HTTP/1.1" 200 12080 "http://shiyanjun.cn/archives/526.html" "Mozilla/5.0 (Windows NT 5.1; rv:11.0) Gecko/20100101 Firefox/11.0"
2 120.43.4.206 - - [21/Feb/2014:10:37:37 +0800] "GET /archives/417.html HTTP/1.1" 200 11464 "http://shiyanjun.cn/archives/417.html/" "Mozilla/5.0 (Windows NT 5.1; rv:11.0) Gecko/20100101 Firefox/11.0"

统计该文件里面IP地址出现频率，来验证Spark集群能够正常计算。另外，我们需要从HDFS中读取这个日志文件，然后统计IP地址频率，最后将结果再保存到HDFS中的指定目录。
首先，需要启动用来提交计算任务的Spark Shell：

1 bin/spark-shell

在Spark Shell上只能使用Scala语言写代码来运行。
然后，执行统计IP地址频率，在Spark Shell中执行如下代码来实现：

1 val file = sc.textFile("hdfs://m1:9000/user/shirdrn/wwwlog20140222.log")
2 val result = file.flatMap(line => line.split("\\s+.*")).map(word => (word, 1)).reduceByKey((a, b) => a + b)

上述的文件hdfs://m1:9000/user/shirdrn/wwwlog20140222.log是输入日志文件。处理过程的日志信息，示例如下所示：

可以看到，输出了经过map和reduce计算后的部分结果。
最后，我们想要将结果保存到HDFS中，只要输入如下代码：

1 result.saveAsTextFile("hdfs://m1:9000/user/shirdrn/wwwlog20140222.log.result")

查看HDFS上的结果数据：
