搭建Spark的单机版集群

[日期:2016-01-18] 来源:Linux社区  作者:ivictor [字体: ]

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

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.

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。
