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)

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.

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。
