创建zybo cluster的spark集群（计算层面）：

1.每个节点都是同样的filesystem，mac地址冲突，故：

vi ./etc/profile

export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:$PATH

export JAVA_HOME=/usr/lib/jdk1.7.0_55

export CLASSPATH=.:$JAVA_HOME/lib/tools.jar

export PATH=$JAVA_HOME/bin:$PATH

export HADOOP_HOME=/root/hadoop-2.4.0

ifconfig eth1 hw ether 00:0a:35:00:01:03

ifconfig eth1 192.168.1.3/24 up

2.生成私匙 id_rsa 与公匙 id_rsa.pub 配置文件

ssh-keygen -t rsa

id_rsa是密钥文件，id_rsa.pub是公钥文件。

3.Worker节点/etc/hosts配置：

具体操作步骤：

ssh

vi /etc/hosts

127.0.0.1 localhost zynq

192.168.1.1 spark1

192.168.1.2 spark2

192.168.1.3 spark3

192.168.1.4 spark4

192.168.1.5 spark5

192.168.1.100 sparkMaster

#::1 localhost ip6-localhost ip6-loopback

Master节点/etc/hosts配置：

4.分发公钥

ssh-copy-id -i ~/.ssh/id_rsa.pub root@spark1

ssh-copy-id -i ~/.ssh/id_rsa.pub root@spark2

ssh-copy-id -i ~/.ssh/id_rsa.pub root@spark3

ssh-copy-id -i ~/.ssh/id_rsa.pub root@spark4

…..

5.配置Master节点

Cd ~/spark-0.9.1-bin-hadoop2/conf

Vi slaves

6.配置java

否则运行pi计算时会出现count找不到的错误（因为pyspark找不到javaruntime）。

cd /usr/bin/

ln -s /usr/lib/jdk1.7.0_55/bin/java java

ln -s /usr/lib/jdk1.7.0_55/bin/javac javac

ln -s /usr/lib/jdk1.7.0_55/bin/jar jar

7.测试运行所有节点

SPARK_MASTER_IP=192.168.1.1 ./sbin/start-all.sh

SPARK_MASTER_IP=192.168.1.100 ./sbin/start-all.sh

成功启动所有节点：

8.查看工作状态：

Jps

Netstat -ntlp

9.开启脚本命令行

MASTER=spark://192.168.1.1:7077 ./bin/pyspark

MASTER=spark://192.168.1.100:7077 ./bin/pyspark

10.测试

from random import random

def sample(p):

x, y = random(), random()

return 1 if x*x + y*y < 1 else 0

count = sc.parallelize(xrange(0, 1000000)).map(sample) \

.reduce(lambda a, b: a + b)

print "Pi is roughly %f" % (4.0 * count / 1000000)

成功进行运算：

正常启动信息：

root@zynq:~/spark-0.9.1-bin-hadoop2# MASTER=spark://192.168.1.1:7077 ./bin/pyspark
