注：在利用CentOS 6.5操作系统安装spark 1.5集群过程中，本人发现Hadoop 2.4.1集群可以顺利搭建，但在Spark 1.5.0集群启动时出现了问题（可能原因是64位操作系统原因，源码需要重新编译，但本人没经过测试），经本人测试在ubuntu 10.04 操作系统上可以顺利成功搭建。大家可以利用CentOS 6.5进行尝试，如果有问题，再利用ubuntu 10.04搭建，所有步骤基本一致

下载地址：http://pan.baidu.com/s/1mgkuKdi
密码：xtm5本实验要求装三台：CentOS 6.5，可以分别安装，也可以安装完一台后克隆两台，具体过程略。初学者，建议三台分别安装。安装后如下图所示：
安装好的虚拟机一般默认使用的是NAT（关于NAT、桥接等虚拟机网络连接方式参见本人博客：http://blog.csdn.net/lovehuangjiaju/article/details/48183485），由于三台机器之间需要互通之外，还需要与本机连通，因此采用将网络连接方式设置为Bridged（三台机器相同的设置），如下图所法：
（1）修改centos_salve01虚拟机主机名：
vim /etc/sysconfig/network/etc/sysconfig/network修改后的内容如下：
（2）vim /etc/sysconfig/network命令修改centos_slave02虚拟机主机名
/etc/sysconfig/network修改后的内容如下：
（3）vim /etc/sysconfig/network命令修改centos_slave03虚拟机主机名
/etc/sysconfig/network修改后的内容如下：
在大家在配置时，修改/etc/sysconfig/network-scripts/ifcfg-eth0文件对应的BOOTPROT=static、IPADDR、NETMASK、GATEWAY及DNS1信息即可
（1）修改centos_salve01虚拟机主机IP地址：
vim /etc/sysconfig/network-scripts/ifcfg-eth0修改后内容如下：
DEVICE="eth0"
BOOTPROTO="static"
HWADDR="00:0c:29:3f:69:4d"
IPV6INIT="yes"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="5315276c-db0d-4061-9c76-9ea86ba9758e"
IPADDR="192.168.1.111"
NETMASK="255.255.255.0"
GATEWAY="192.168.1.1"
DNS1="8.8.8.8"
（2）修改centos_salve02虚拟机主机IP地址：
vim /etc/sysconfig/network-scripts/ifcfg-eth0修改后内容如下：
DEVICE="eth0"
BOOTPROTO="static"
HWADDR="00:0c:29:64:f9:80"
IPV6INIT="yes"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="5315276c-db0d-4061-9c76-9ea86ba9758e"
IPADDR="192.168.1.112"
NETMASK="255.255.255.0"
GATEWAY="192.168.1.1"
DNS1="8.8.8.8"
（3）修改centos_salve03虚拟机主机IP地址：
vim /etc/sysconfig/network-scripts/ifcfg-eth0修改后内容如下：
DEVICE="eth0"
BOOTPROTO="static"
HWADDR="00:0c:29:1e:80:b1"
IPV6INIT="yes"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="5315276c-db0d-4061-9c76-9ea86ba9758e"
IPADDR="192.168.1.113"
NETMASK="255.255.255.0"
GATEWAY="192.168.1.1"
DNS1="8.8.8.8"
/etc/sysconfig/network-scripts/ifcfg-eth0文件内容解析：
DEVICE=eth0 //指出设备名称
BOOTPROT=static //启动类型 dhcp|static，使用桥接模式，必须是static
HWADDR=00:06:5B:FE:DF:7C //硬件Mac地址
IPADDR=192.168.0.2 //IP地址
NETMASK=255.255.255.0 //子网掩码
NETWORK=192.168.0.0 //网络地址
GATEWAY=192.168.0.1 //网关地址
ONBOOT=yes //是否启动应用
TYPE=Ethernet //网络类型设置完成后，使用
service network restart命令重新启动网络，配置即可生效。
（1）修改centos_salve01主机名与IP地址映射
vim /etc/hosts设置内容如下：
127.0.0.1 slave01.example.com localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 slave01.example.com
192.168.1.111 slave01.example.com
192.168.1.112 slave02.example.com
192.168.1.113 slave03.example.com
具体如下图：（2）修改centos_salve02主机名与IP地址映射
vim /etc/hosts设置内容如下：
127.0.0.1 slave02.example.com localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 slave02.example.com
192.168.1.111 slave01.example.com
192.168.1.112 slave02.example.com
192.168.1.113 slave03.example.com
具体如下图：
（3）修改centos_salve03主机名与IP地址映射
vim /etc/hosts设置内容如下：
127.0.0.1 slave03.example.com localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 slave03.example.com
192.168.1.111 slave01.example.com
192.168.1.112 slave02.example.com
192.168.1.113 slave03.example.com
采用下列命令设置各主机DNS（三台机器进行相同的设置)
vim /etc/resolv.conf 设置后的内容：
# Generated by NetworkManager
search example.com
nameserver 8.8.8.8
8.8.8.8为Google提供的DNS服务器
前面所有的配置完成后，重启centos_salve01、centos_salve02、centos_salve03使主机名设置生效，然后分别在三台机器上作如下测试命令：
下面只给出在centos_salve01虚拟机上的测试
[root@slave01 ~]# ping slave02.example.com

测试外网的连通性（我在装的时候，8.8.8.8，已经被禁用….心中一万头cnm）：
[root@slave01 ~]# ping www.baidu.com
ping: unknown host www.baidu.com
[root@slave01 ~]# ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

From 192.168.1.111 icmp_seq=7 Destination Host Unreachable
From 192.168.1.111 icmp_seq=8 Destination Host Unreachable
#### (1) OpenSSH安装
如果大家在配置时，ping 8.8.8.8能够ping通，则主机能够正常上网；如果不能上网，则将网络连接方式重新设置为NAT，并修改网络配置文件为dhcp方式。在保证网络连通的情况下执行下列命令：
yum install openssh-server#### (2) 无密码登录实现
使用以下命令生成相应的密钥（三台机器进行相同的操作）
ssh-keygen -t rsa 执行过程一直回车即可
[root@slave01 ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
4e:2f:39:ed:f4:32:2e:a3:55:62:f5:8a:0d:c5:2c:16 root@slave01.example.com
The key‘s randomart image is:
+--[ RSA 2048]----+
| E |
| + |
| o = |
| . + . |
| S . . |
| + X . |
| B * |
| .o=o. |
| .. +oo. |
+-----------------+
生成的文件分别为/root/.ssh/id_rsa（私钥）、/root/.ssh/id_rsa.pub（公钥）
完成后将公钥拷贝到要免登陆的机器上（三台可进行相同操作）：
ssh-copy-id -i slave01.example.com
ssh-copy-id -i slave02.example.com
ssh-copy-id -i slave03.example.com集群搭建相关软件下载地址：
链接：http://pan.baidu.com/s/1sjIG3b3 密码：38gh下载后将所有软件都放置在E盘的share目录下:
设置share文件夹为虚拟机的共享目录，如下图所示：
在linux系统中，采用
[root@slave01 /]# cd /mnt/hgfs/share
[root@slave01 share]# ls命令可以切换到该目录下，如下图
Spark官方要求的JDK、Scala版本
Spark runs on Java 7+, Python 2.6+ and R 3.1+. For the Scala API, Spark 1.5.0 uses Scala 2.10. You will need to use a compatible Scala version (2.10.x).在根目录下创建sparkLearning目前，后续所有相关软件都放置在该目录下，代码如下：
[root@slave01 /]# mkdir /sparkLearning
[root@slave01 /]# ls
bin etc lib media proc selinux sys var
boot hadoopLearning lib64 mnt root sparkLearning tmp
dev home lost+found opt sbin srv usr
将共享目录中的jdk安装包复制到/sparkLearning目录
[root@slave01 share]# cp /mnt/hgfs/share/jdk-8u40-linux-x64.gz /sparkLearning/
[root@slave01 share]# cd /sparkLearning/
//解压
[root@slave01 sparkLearning]# tar -zxvf jdk-8u40-linux-x64.gz
设置环境变量：
[root@slave01 sparkLearning]# vim /etc/profile在文件最后添加：
export JAVA_HOME=/sparkLearning/jdk1.8.0_40
export PATH=${JAVA_HOME}/bin:$PATH如下图：
测试配置是否成功：
//使修改后的配置生效
[root@slave01 sparkLearning]# source /etc/profile
//环境变量是否已经设置
[root@slave01 sparkLearning]# $JAVA_HOME
bash: /sparkLearning/jdk1.8.0_40: is a directory
//测试java是否安装配置成功
[root@slave01 sparkLearning]# java -version
java version "1.8.0_40"
Java(TM) SE Runtime Environment (build 1.8.0_40-b25)
Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)
//复制文件到sparkLearning目录下
[root@slave01 sparkLearning]# cp /mnt/hgfs/share/scala-2.10.4.tgz .
//解压
[root@slave01 sparkLearning]# tar -zxvf scala-2.10.4.tgz > /dev/null
[root@slave01 sparkLearning]# vim /etc/profile将/etc/profile文件末尾内容修改如下：
export JAVA_HOME=/sparkLearning/jdk1.8.0_40
export SCALA_HOME=/sparkLearning/scala-2.10.4
export PATH=${JAVA_HOME}/bin:${SCALA_HOME}/bin:$PATH测试Scala是否安装成功
[root@slave01 sparkLearning]# source /etc/profile
[root@slave01 sparkLearning]# $SCALA_HOME
bash: /sparkLearning/scala-2.10.4: is a directory
[root@slave01 sparkLearning]# scala -version
Scala code runner version 2.10.4 -- Copyright 2002-2013, LAMP/EPFL
[root@slave01 sparkLearning]# cp /mnt/hgfs/share/zookeeper-3.4.5.tar.gz .
[root@slave01 sparkLearning]# tar -zxvf zookeeper-3.4.5.tar.gz > /dev/null
[root@slave01 sparkLearning]# cp zookeeper-3.4.5/conf/zoo_sample.cfg zoo.cfg
[root@slave01 sparkLearning]# vim zoo.cfg
修改dataDir为：
dataDir=/sparkLearning/zookeeper-3.4.5/zookeeper_data
在文件末尾添加如下内容：
server.1=slave01.example.com:2888:3888
server.2=slave02.example.com:2888:3888
server.3=slave03.example.com:2888:3888
如图所示：
创建ZooKeeper集群数据保存目录
[root@slave01 sparkLearning]# cd zookeeper-3.4.5/
[root@slave01 zookeeper-3.4.5]# mkdir zookeeper_data
[root@slave01 zookeeper-3.4.5]# cd zookeeper_data/
[root@slave01 zookeeper_data]# touch myid
[root@slave01 zookeeper_data]# echo 1 > myid
将slave01.example.com（centos_slave01）上的sparkLearning目录拷贝到另外两台服务器上：
[root@slave01 /]# scp -r /sparkLearning slave02.example.com:/
[root@slave01 /]# scp -r /sparkLearning slave03.example.com://etc/profile文件也进行覆盖
[root@slave01 /]# scp /etc/profile slave02.example.com:/etc/profile
[root@slave01 /]# scp /etc/profile slave03.example.com:/etc/profile修改zookeeper_data中的myid信息：
//配置slave02.example.com上的myid
[root@slave01 /]# ssh salve02.example.com
[root@slave02 ~]# echo 2 > /sparkLearning/zookeeper-3.4.5/zookeeper_data/myid
[root@slave02 ~]# more /sparkLearning/zookeeper-3.4.5/zookeeper_data/myid
2
//配置slave03.example.com上的myid
[root@slave02 ~]# ssh slave03.example.com
Last login: Fri Sep 18 01:33:29 2015 from slave01.example.com
[root@slave03 ~]# echo 3 > /sparkLearning/zookeeper-3.4.5/zookeeper_data/myid
[root@slave03 ~]# more /sparkLearning/zookeeper-3.4.5/zookeeper_data/myid
3
如此便完成配置，下面对集群进行测试：
//在slave03.example.com主机上
[root@slave03 ~]# cd /sparkLearning/zookeeper-3.4.5/bin
[root@slave03 bin]# ls

打开浏览器，输入http://slave01.example.com:8088/，可以得到hadoop集群管理界面:
输入http://slave01.example.com:50070 可以得到HDFS管理界面
至此Hadoop集群配置成功

[root@slave01 sparkLearning]# tar -zxvf spark-1.5.0-bin-hadoop2.4.tgz > /dev/null
[root@slave01 sparkLearning]# vim /etc/profile将/etc/profile内容修改如下：

//复制模板文件
[root@slave01 conf]# cp spark-env.sh.template spark-env.sh
[root@slave01 conf]# vim spark-env.sh在spark-env.sh文件中添加如下内容：

因为本人机器上装了Ambari Server，占用了8080端口，而Spark Master默认端是8080，因此将sbin/start-master.sh中的SPARK_MASTER_WEBUI_PORT修改为8888
if [ "$SPARK_MASTER_WEBUI_PORT" = "" ]; then
SPARK_MASTER_WEBUI_PORT=8888

.....省略.....................没找到具体原因，在ubuntu 10.04服务器上进行相同的配置，集群搭建却成功了（心中一万头…..），运行界面如下:
采用下列命上传spark-1.5.0-bin-hadoop2.4目录下的README.md文件到相应的根目录。
hadoop dfs -put README.md 如下图：
进入/spark-1.5.0-bin-hadoop2.4/bin目录，启动./spark-shell，如下图所示：
执行REDME.md文件的wordcount操作：
scala> val textCount = sc.textFile(“README.md”).filter(line => line.contains(“Spark”)).count()
如下图：
执行结果如下图：
至此，Spark 1.5集群搭建成功。
