Hadoop+Spark:集群环境搭建

• 环境准备：

在虚拟机下，大家三台Linux ubuntu 14.04 server x64 系统（下载地址：http://releases.ubuntu.com/14.04.2/ubuntu-14.04.2-server-amd64.iso）:

192.168.1.200 master

192.168.1.201 node1

192.168.1.202 node2

• 在Master上安装Spark环境：

Spark集群环境搭建：

搭建hadoop集群使用hadoop版本是hadoop2.6.4(这里hadoop我已经安装完成，具体如何安装hadoop具体请参考我的文章：《Hadoop:搭建hadoop集群》)

搭建spark这里使用spark版本是spark1.6.2（spark-1.6.2-bin-hadoop2.6.tgz）

1、下载安装包到master虚拟服务器：

在线下载：

hadoop@master:~/ wget http://mirror.bit.edu.cn/apache/spark/spark-1.6.2/spark-1.6.2-bin-hadoop2.6.tgz

离线上传到集群：

2、解压spark安装包到master虚拟服务器/usr/local/spark下，并分配权限：

#解压到/usr/local/下
hadoop@master:~$ sudo tar -zxvf spark-1.6.2-bin-hadoop2.6.tgz -C /usr/local/
hadoop@master:~$ cd /usr/local/
hadoop@master:/usr/local$ ls
bin  games   include  man   share                      src
etc  hadoop  lib      sbin  spark-1.6.2-bin-hadoop2.6
#重命名 为spark
hadoop@master:/usr/local$ sudo mv spark-1.6.2-bin-hadoop2.6/ spark/
hadoop@master:/usr/local$ ls
bin  etc  games  hadoop  include  lib  man  sbin  share  spark  src
#分配权限
hadoop@master:/usr/local$ sudo chown -R hadoop:hadoop spark
hadoop@master:/usr/local$

3、在master虚拟服务器/etc/profile中添加Spark环境变量：

　编辑/etc/profile文件

sudo vim /etc/profile

在尾部添加$SPARK_HOME变量，添加后，目前我的/etc/profile文件尾部内容如下：

export JAVA_HOME=/usr/lib/jvm/java-8-oracle
export JRE_HOME=/usr/lib/jvm/java-8-oracle
export SCALA_HOME=/opt/scala/scala-2.10.5
# add hadoop bin/ directory to PATH
export HADOOP_HOME=/usr/local/hadoop
export SPARK_HOME=/usr/local/spark
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$JAVA_HOME:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$SCALA_HOME/bin:$SPARK_HOME/bin:$PATH
export CLASSPATH=$CLASS_PATH::$JAVA_HOME/lib:$JAVA_HOME/jre/lib

生效：

source /etc/profile

• 在Master配置Spark：

1、配置master虚拟服务器hadoop-env.sh文件：

sudo vim /usr/local/spark/conf/hadoop-env.sh

注意：默认情况下没有hadoop-env.sh和slaves文件，而是*.template文件，需要重命名：

hadoop@master:/usr/local/spark/conf$ ls
docker.properties.template  metrics.properties.template   spark-env.sh
fairscheduler.xml.template  slaves.template
log4j.properties.template   spark-defaults.conf.template
hadoop@master:/usr/local/spark/conf$ sudo vim spark-env.sh
hadoop@master:/usr/local/spark/conf$ mv  slaves.template slaves

在文件末尾追加如下内容：

export STANDALONE_SPARK_MASTER_HOST=192.168.1.200
export SPARK_MASTER_IP=192.168.1.200
export SPARK_WORKER_CORES=1
#every slave node start work instance count
export SPARK_WORKER_INSTANCES=1
export SPARK_MASTER_PORT=7077
export SPARK_WORKER_MEMORY=1g
export MASTER=spark://${SPARK_MASTER_IP}:${SPARK_MASTER_PORT}
export SCALA_HOME=/opt/scala/scala-2.10.5
export JAVA_HOME=/usr/lib/jvm/java-8-oracle
export SPARK_HISTORY_OPTS="-Dspark.history.fs.logDirectory=hdfs://192.168.1.200:9000/SparkEventLog"
export SPARK_WORKDER_OPTS="-Dspark.worker.cleanup.enabled=true"
export HADOOP_CONF_DIR=/usr/local/hadoop/etc/hadoop

2、配置master虚拟服务器下slaves文件：

sudo vim /usr/local/spark/conf/slaves

在slaves文件中内容如下：

192.168.1.201
192.168.1.202

注意：每行写一个机器的ip。

3、Master虚拟机下/usr/local/spark/目录下创建logs文件夹，并分配777权限：

hadoop@master:/usr/local/spark$ mkdir logs
hadoop@master:/usr/local/spark$ chmod 777 logs

• 复制Master虚拟服务器上的/usr/loca/spark下文件到所有slaves节点（node1、node2）下：

1、复制Master虚拟服务器上/usr/local/spark/安装文件到各个salves(node1、node2)上：

注意：拷贝钱需要在ssh到所有salves节点（node1、node2）上，创建/usr/local/spark/目录，并分配777权限。

hadoop@master:/usr/local/spark/conf$ cd ~/
hadoop@master:~$ sudo chmod 777 /usr/local/spark
hadoop@master:~$ scp -r /usr/local/spark hadoop@node1:/usr/local
scp: /usr/local/spark: Permission denied
hadoop@master:~$ sudo scp -r /usr/local/spark hadoop@node1:/usr/local
hadoop@node1's password:
scp: /usr/local/spark: Permission denied
hadoop@master:~$ sudo chmod 777 /usr/local/spark
hadoop@master:~$ ssh node1

2、修改所有salves节点(node1、node2)上/etc/profile，追加$SPARK_HOME环境变量:

注意：一般都会遇到权限问题。最好登录到各个salves节点(node1、node2)上手动编辑/etc/profile。

修改后的所有salves上/etc/profile文件与master节点上/etc/profile文件配置一致。

• 在Master启动spark并验证是否配置成功：

1、启动命令：

一般要确保hadoop已经启动，之后才启动spark

hadoop@master:~$ cd /usr/local/spark/
hadoop@master:/usr/local/spark$ ./sbin/start-all.sh

2、验证是否启动成功：

方法一、jps
