1. 基础环境

vi /etc/hosts
192.168.74.10  host196
192.168.74.29  host197
192.168.74.30  host198

安装jdk,zookeeper,hadoop

1. 安装步骤

tar -zxvf spark-2.3.2-bin-hadoop2.7.tgz -C /opt/
cd /opt/spark-2.3.2-bin-hadoop2.7/
cd conf/

cp spark-env.sh.template spark-env.sh
vi spark-env.sh
JAVA_HOME=/usr/local/jdk1.8.0_111
HADOOP_CONF_DIR=/opt/hadoop-2.8.5/etc/hadoop
SPARK_DAEMON_JAVA_OPTS="-Dspark.deploy.recoveryMode=ZOOKEEPER -Dspark.deploy.zookeeper.url=192.168.74.10:2181-Dspark.deploy.zookeeper.dir=/spark"

cp slaves.template slaves
vi slaves
host196
host197
host198

scp -r spark-2.3.2-bin-hadoop2.7/ host197:/opt/
scp -r spark-2.3.2-bin-hadoop2.7/ host198:/opt/

1. 启动、停止服务

• 启动

ssh host196
sbin/start-all.sh

ssh host197
sbin/start-master.sh

访问：http://host196:8080

• 停止

ssh host196
sbin/stop-all.sh

ssh host197
sbin/stop-master.sh

1. 基本测试

使用spark-shell来测试

[root@host198 spark-2.3.2-bin-hadoop2.7]# bin/spark-shell
