centos安装spark1.6

一.环境

  • 软件环境
    centos7
    spark1.6
    jdk1.7
    scala2.10
  • 硬件环境
    192.168.1.21(master,node21)
    192.168.1.22(slave,node22)
    192.168.1.23(slave,node23)

二.配置jdk、scala运行环境

  • jdk安装(我习惯用tar.gz包)
tar -xzvf jdk1.7.tar.gz -C /opt/
mv /opt/jdk1.7 /opt/jdk
  • scala安装
tar xzvf scala-2.10.4.tgz -C /opt
mv /opt/scala-2.10.4 /opt/scala
  • 配置环境变量
vi /etc/profile
(添加下面的配置)
export JAVA_HOME=/opt/jdk
export PATH=$JAVA_HOME/bin:$PATH

export SCALA_HOME=/opt/scala/
export PATH=$SCALA_HOME/bin:$PATH
##保存
source /etc/profile
  • 测试
java -version
scala -version

三.spark安装

tar -xzvf spark-1.6.0-bin-2.6.4.tgz -C /opt
mv /opt/spark-1.6.0-bin-2.6.4 /opt/spark
  • 配置slaves
cd /opt/spark/conf
cp slaves.template slaves
vi slaves
(添加下面内容,填写hostname或者ip都可以,spark对两个都识别)
node22
node23
  • 配置spark-env.sh
cd /opt/spark/conf
cp spark-env.sh.template spark-env.sh
vi spark-env.sh
(添加下面内容,不添加java_home,slaves节点会启动不了)
export JAVA_HOME=/opt/jdk

四.部署到slave节点上面

  • jdk
scp -r /opt/jdk 192.168.1.22:/opt/
scp -r /opt/jdk 192.168.1.23:/opt/
  • scala
scp -r /opt/scala 192.168.1.22:/opt
scp -r /opt/scala 192.168.1.23:/opt
  • spark
scp -r /opt/spark 192.168.1.22:/opt
scp -r /opt/spark 192.168.1.23:/opt
  • 环境变量
scp /etc/profile 192.168.1.22:/etc
scp /etc/profile 192.168.1.23:/etc
(在所有slave上,执行下面)
source /etc/profile

5.启动

master节点上执行

/opt/spark/sbin/start-all.sh
