一. 准备工作

1. 准备三台虚拟机,网络互联,安装jdk,配置JAVA_HOME

2. 对虚拟机进行hosts配置,以便于免密操作

 

 

3. 三台虚拟机进行免密登录配置

  3.1  执行 ssh-keygen -t rsa 命令,然后一直回车,会在/root/.ssh/ 目标下面生成两个文件id_rsa(私钥), id_rsa.pub(公钥) 

  3.2  将三台虚拟机的cat  id_rsa.pub >> /root/.ssh/authorized_keys, 最终三台服务器的authorized_keys文件内容如下

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDOSBn4YN3B3s8LgP/FM5oVckeKBuLOClg1CEuc7Fk6iv6W38UxEm9L6ktetB4ykiUvZzuyyuhE3jV0PYsSe4lB/09k/IphR0wLN4vH4xM11CuHGHGNLNGe54l/YJM6QGIs/0pa1/dExPqDJVxK5ENzU1fJ2MV+pD/65P5j6WBNdRrNkvCq8EAqN8h/dBU06NsAB82YM8FgUDKHd1ufs803cnMEszlURjEian3QK+BVkBcacWGXru0keAtTHVEeouk+kEeR1EIhnjq1/T0ZD012OYZTak1I0gf0BVuSH2j3PG5/DFix+S8e27tnwKL/VJ+sV66U134vFbnNdvG2/3XH root@spark02

  如此,三台虚拟机就可以免密访问了

二. 正式安装spark

1. 上传,并解压安装包 spark-2.4.4-bin-hadoop2.7.tgz

2. 重命令

  mv spark-2.4.4-bin-hadoop2.7 spark

3.配置spark的环境变量

  vi /etc/profile

    export SPARK_HOME=/root/spark
    export PATH=$PATH:$SPARK_HOME/bin:$SPARK_HOME/sbin

  source /etc/profile

 

4. 修改spark配置文件

 cd /root/spark/conf

 cp slaves.template slaves

 vim slaves
  # 配置slave的地址

  spark02

  spark03

5. 运行环境配置 

cp spark-env.sh.template spark-env.sh

5.1 单master配置

#配置jdk
export JAVA_HOME=/root//jdk8
export SPARK_MASTER_IP=spark01
export SPARK_MASTER_PORT=7077

5.2 多master配置(ha)
#配置jdk
export JAVA_HOME=/root/jdk8
export SPARK_MASTER_PORT=7077
##多master时添加以下配置项zookeeper
export SPARK_DAEMON_JAVA_OPTS="-Dspark.deploy.recoveryMode=ZOOKEEPER -Dspark.deploy.zookeeper.url=mini1,mini2,mini3 -Dspark.deploy.zookeeper.dir=/spark"

6. 分发spark安装包到spark02,spark03

  scp -r spark root@spark02:/root/

  scp -r spark root@spark02:/root/

7. 启动
  sbin/start-all.sh

   停止
  sbin/stop-all.sh

 -------------------------------

  多master测试:
  sbin/start-all.sh
  然后在spark02上再启一个master
  sbin/start-master.sh

  通过ui页面就能看到master一主一备
  http://spark01:8080/
  http://spark02:8080/

 

8 .运行测试

./bin/run-example SparkPi 10
不报错即可
