搭建Spark的单机版集群

搭建Spark的单机版集群
一、创建用户
# useradd spark
# passwd spark
二、下载软件
JDK，Scala，SBT，Maven
版本信息如下：
JDK jdk-7u79-linux-x64.gz
Scala scala-2.10.5.tgz
SBT sbt-0.13.7.zip
Maven apache-maven-3.2.5-bin.tar.gz
注意：如果只是安装Spark环境，则只需JDK和Scala即可，SBT和Maven是为了后续的源码编译。
三、解压上述文件并进行环境变量配置
# cd /usr/local/
# tar xvf /root/jdk-7u79-linux-x64.gz
# tar xvf /root/scala-2.10.5.tgz
# tar xvf /root/apache-maven-3.2.5-bin.tar.gz
# unzip /root/sbt-0.13.7.zip
修改环境变量的配置文件
# vim /etc/profile
export JAVA_HOME=/usr/local/jdk1.7.0_79 export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export SCALA_HOME=/usr/local/scala-2.10.5 export MAVEN_HOME=/usr/local/apache-maven-3.2.5 export SBT_HOME=/usr/local/sbt export PATH=$PATH:$JAVA_HOME/bin:$SCALA_HOME/bin:$MAVEN_HOME/bin:$SBT_HOME/bin
使配置文件生效
# source /etc/profile
测试环境变量是否生效
# java –version
java version "1.7.0_79" Java(TM) SE Runtime Environment (build 1.7.0_79-b15) Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)
# scala –version
Scala code runner version 2.10.5 -- Copyright 2002-2013, LAMP/EPFL
# mvn –version
Apache Maven 3.2.5 (12a6b3acb947671f09b81f49094c53f426d8cea1; 2014-12-15T01:29:23+08:00) Maven home: /usr/local/apache-maven-3.2.5 Java version: 1.7.0_79, vendor: Oracle Corporation Java home: /usr/local/jdk1.7.0_79/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "3.10.0-229.el7.x86_64", arch: "amd64", family: "unix"
# sbt --version
sbt launcher version 0.13.7
四、主机名绑定
[root@spark01 ~]# vim /etc/hosts
192.168.244.147 spark01
五、配置spark
切换到spark用户下
下载Hadoop和spark，可使用wget命令下载
spark-1.4.0 http://d3kbcqa49mib13.cloudfront.net/spark-1.4.0-bin-hadoop2.6.tgz
Hadoop http://mirror.bit.edu.cn/apache/hadoop/common/hadoop-2.6.0/hadoop-2.6.0.tar.gz
解压上述文件并进行环境变量配置
修改spark用户环境变量的配置文件
[spark@spark01 ~]$ vim .bash_profile
export SPARK_HOME=$HOME/spark-1.4.0-bin-hadoop2.6 export HADOOP_HOME=$HOME/hadoop-2.6.0 export HADOOP_CONF_DIR=$HOME/hadoop-2.6.0/etc/hadoop export PATH=$PATH:$SPARK_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin
使配置文件生效
[spark@spark01 ~]$ source .bash_profile
修改spark配置文件
[spark@spark01 ~]$ cd spark-1.4.0-bin-hadoop2.6/conf/
[spark@spark01 conf]$ cp spark-env.sh.template spark-env.sh
[spark@spark01 conf]$ vim spark-env.sh
在后面添加如下内容：
export SCALA_HOME=/usr/local/scala-2.10.5 export SPARK_MASTER_IP=spark01 export SPARK_WORKER_MEMORY=1500m export JAVA_HOME=/usr/local/jdk1.7.0_79
有条件的童鞋可将SPARK_WORKER_MEMORY适当设大一点，因为我虚拟机内存是2G，所以只给了1500m。
配置slaves
[spark@spark01 conf]$ cp slaves slaves.template
[spark@spark01 conf]$ vim slaves
将localhost修改为spark01
启动master
[spark@spark01 spark-1.4.0-bin-hadoop2.6]$ sbin/start-master.sh
starting org.apache.spark.deploy.master.Master, logging to /home/spark/spark-1.4.0-bin-hadoop2.6/sbin/../logs/spark-spark-org.apache.spark.deploy.master.Master-1-spark01.out
查看上述日志的输出内容
[spark@spark01 spark-1.4.0-bin-hadoop2.6]$ cd logs/
[spark@spark01 logs]$ cat spark-spark-org.apache.spark.deploy.master.Master-1-spark01.out

New state: ALIVE
从日志中也可看出，master启动正常
下面来看看master的 web管理界面，默认在8080端口
启动worker
[spark@spark01 spark-1.4.0-bin-hadoop2.6]$ sbin/start-slaves.sh spark://spark01:7077
spark01: Warning: Permanently added 'spark01,192.168.244.147' (ECDSA) to the list of known hosts. spark@spark01's password: spark01: starting org.apache.spark.deploy.worker.Worker, logging to /home/spark/spark-1.4.0-bin-hadoop2.6/sbin/../logs/spark-spark-org.apache.spark.deploy.worker.Worker-1-spark01.out
输入spark01上spark用户的密码
可通过日志的信息来确认workder是否正常启动，因信息太多，在这里就不贴出了。
[spark@spark01 spark-1.4.0-bin-hadoop2.6]$ cd logs/
[spark@spark01 logs]$ cat spark-spark-org.apache.spark.deploy.worker.Worker-1-spark01.out
启动spark shell
[spark@spark01 spark-1.4.0-bin-hadoop2.6]$ bin/spark-shell --master spark://spark01:7077

打开spark shell以后，可以写一个简单的程序，say hello to the world
scala> println("helloworld")
helloworld再来看看spark的web管理界面，可以看出，多了一个Workders和Running Applications的信息
至此，Spark的伪分布式环境搭建完毕，
有以下几点需要注意：
1. 上述中的Maven和SBT是非必须的，只是为了后续的源码编译，所以，如果只是单纯的搭建Spark环境，可不用下载Maven和SBT。
2. 该Spark的伪分布式环境其实是集群的基础，只需修改极少的地方，然后copy到slave节点上即可，鉴于篇幅有限，后文再表。
