- 環境准備：
在虛擬機下，大家三台Linux ubuntu 14.04 server x64 系統（下載地址：http://releases.ubuntu.com/14.04.2/ubuntu-14.04.2-server-amd64.iso）:
192.168.1.200 master
192.168.1.201 node1
192.168.1.202 node2
- 在Master上安裝Spark環境：
Spark集群環境搭建：
搭建hadoop集群使用hadoop版本是hadoop2.6.4(這里hadoop我已經安裝完成，具體如何安裝hadoop具體請參考我的文章：《Hadoop:搭建hadoop集群》)
搭建spark這里使用spark版本是spark1.6.2（spark-1.6.2-bin-hadoop2.6.tgz）
1、下載安裝包到master虛擬服務器：
在線下載：
hadoop@master:~/ wget http://mirror.bit.edu.cn/apache/spark/spark-1.6.2/spark-1.6.2-bin-hadoop2.6.tgz
離線上傳到集群：
2、解壓spark安裝包到master虛擬服務器/usr/local/spark下，並分配權限：
#解壓到/usr/local/下
hadoop@master:~$ sudo tar -zxvf spark-1.6.2-bin-hadoop2.6.tgz -C /usr/local/ hadoop@master:~$ cd /usr/local/ hadoop@master:/usr/local$ ls bin games include man share src etc hadoop lib sbin spark-1.6.2-bin-hadoop2.6
#重命名 為spark hadoop@master:/usr/local$ sudo mv spark-1.6.2-bin-hadoop2.6/ spark/ hadoop@master:/usr/local$ ls bin etc games hadoop include lib man sbin share spark src
#分配權限 hadoop@master:/usr/local$ sudo chown -R hadoop:hadoop spark hadoop@master:/usr/local$
3、在master虛擬服務器/etc/profile中添加Spark環境變量：
編輯/etc/profile文件
sudo vim /etc/profile
在尾部添加$SPARK_HOME變量，添加后，目前我的/etc/profile文件尾部內容如下：
export JAVA_HOME=/usr/lib/jvm/java-8-oracle export JRE_HOME=/usr/lib/jvm/java-8-oracle export SCALA_HOME=/opt/scala/scala-2.10.5 # add hadoop bin/ directory to PATH export HADOOP_HOME=/usr/local/hadoop export SPARK_HOME=/usr/local/spark export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$JAVA_HOME:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$SCALA_HOME/bin:$SPARK_HOME/bin:$PATH export CLASSPATH=$CLASS_PATH::$JAVA_HOME/lib:$JAVA_HOME/jre/lib
生效：
source /etc/profile
- 在Master配置Spark：
1、配置master虛擬服務器hadoop-env.sh文件：
sudo vim /usr/local/spark/conf/hadoop-env.sh
注意：默認情況下沒有hadoop-env.sh和slaves文件，而是*.template文件，需要重命名：
hadoop@master:/usr/local/spark/conf$ ls docker.properties.template metrics.properties.template spark-env.sh fairscheduler.xml.template slaves.template log4j.properties.template spark-defaults.conf.template hadoop@master:/usr/local/spark/conf$ sudo vim spark-env.sh hadoop@master:/usr/local/spark/conf$ mv slaves.template slaves
在文件末尾追加如下內容：
export STANDALONE_SPARK_MASTER_HOST=192.168.1.200 export SPARK_MASTER_IP=192.168.1.200 export SPARK_WORKER_CORES=1 #every slave node start work instance count export SPARK_WORKER_INSTANCES=1 export SPARK_MASTER_PORT=7077 export SPARK_WORKER_MEMORY=1g export MASTER=spark://${SPARK_MASTER_IP}:${SPARK_MASTER_PORT} export SCALA_HOME=/opt/scala/scala-2.10.5 export JAVA_HOME=/usr/lib/jvm/java-8-oracle export SPARK_HISTORY_OPTS="-Dspark.history.fs.logDirectory=hdfs://192.168.1.200:9000/SparkEventLog" export SPARK_WORKDER_OPTS="-Dspark.worker.cleanup.enabled=true" export HADOOP_CONF_DIR=/usr/local/hadoop/etc/hadoop
2、配置master虛擬服務器下slaves文件：
sudo vim /usr/local/spark/conf/slaves
在slaves文件中內容如下：
192.168.1.201 192.168.1.202
注意：每行寫一個機器的ip。
3、Master虛擬機下/usr/local/spark/目錄下創建logs文件夾，並分配777權限：
hadoop@master:/usr/local/spark$ mkdir logs hadoop@master:/usr/local/spark$ chmod 777 logs
- 復制Master虛擬服務器上的/usr/loca/spark下文件到所有slaves節點（node1、node2）下：
1、復制Master虛擬服務器上/usr/local/spark/安裝文件到各個salves(node1、node2)上：
注意：拷貝錢需要在ssh到所有salves節點（node1、node2）上，創建/usr/local/spark/目錄，並分配777權限。
hadoop@master:/usr/local/spark/conf$ cd ~/ hadoop@master:~$ sudo chmod 777 /usr/local/spark hadoop@master:~$ scp -r /usr/local/spark hadoop@node1:/usr/local scp: /usr/local/spark: Permission denied hadoop@master:~$ sudo scp -r /usr/local/spark hadoop@node1:/usr/local hadoop@node1's password: scp: /usr/local/spark: Permission denied hadoop@master:~$ sudo chmod 777 /usr/local/spark hadoop@master:~$ ssh node1 Welcome to Ubuntu 14.04.2 LTS (GNU/Linux 3.16.0-30-generic x86_64) * Documentation: https://help.ubuntu.com/ System information as of Fri Sep 23 16:40:31 UTC 2016 System load: 0.08 Processes: 400 Usage of /: 12.2% of 17.34GB Users logged in: 0 Memory usage: 5% IP address for eth0: 192.168.1.201 Swap usage: 0% Graph this data and manage this system at: https://landscape.canonical.com/ New release '16.04.1 LTS' available.

2、修改所有salves節點(node1、node2)上/etc/profile，追加$SPARK_HOME環境變量:
注意：一般都會遇到權限問題。最好登錄到各個salves節點(node1、node2)上手動編輯/etc/profile。
hadoop@master:~$ ssh node1 Welcome to Ubuntu 14.04.2 LTS (GNU/Linux 3.16.0-30-generic x86_64) * Documentation: https://help.ubuntu.com/ System information as of Fri Sep 23 16:42:44 UTC 2016 System load: 0.01 Processes: 400 Usage of /: 12.2% of 17.34GB Users logged in: 0 Memory usage: 5% IP address for eth0: 192.168.1.201 Swap usage: 0% Graph this data and manage this system at: https://landscape.canonical.com/ New release '16.04.1 LTS' available.

修改后的所有salves上/etc/profile文件與master節點上/etc/profile文件配置一致。
- 在Master啟動spark並驗證是否配置成功：
1、啟動命令：
一般要確保hadoop已經啟動，之后才啟動spark
hadoop@master:~$ cd /usr/local/spark/ hadoop@master:/usr/local/spark$ ./sbin/start-all.sh
2、驗證是否啟動成功：
