Spark安装(standalone)

文档：http://spark.apache.org/docs/latest/spark-standalone.html

安装scala
https://www.scala-lang.org/download/

wget -P /opt/downloads https://downloads.lightbend.com/scala/2.13.0/scala-2.13.0.rpm
rpm -ivh /opt/downloads/scala-2.13.0.rpm

环境变量
vim /etc/profile
export SCALA_HOME=/usr/scala-2.13.0
export PATH=$PATH:$SCALA_HOME/bin

生效

source /etc/profile

检查
scala -version

集群（略）

安装Spark
https://www.apache.org/dyn/closer.lua/spark/spark-2.4.3/spark-2.4.3-bin-hadoop2.7.tgz

wget -P /opt/downloads http://mirrors.tuna.tsinghua.edu.cn/apache/spark/spark-2.4.3/spark-2.4.3-bin-hadoop2.7.tgz
wget -P /opt/downloads http://mirror.bit.edu.cn/apache/spark/spark-2.4.3/spark-2.4.3-bin-hadoop2.7.tgz
tar zxvf /opt/downloads/spark-2.4.3-bin-hadoop2.7.tgz -C /opt
mv /opt/spark-2.4.3-bin-hadoop2.7/ /opt/spark

cp /opt/spark/conf/spark-env.sh.template /opt/spark/conf/spark-env.sh
vim /opt/spark/conf/spark-env.sh

export JAVA_HOME=/usr/java/jdk1.8.0_201-amd64
export SCALA_HOME=/usr/share/scala
export HADOOP_HOME=/opt/hadoop
export HADOOP_CONF_DIR=/opt/hadoop/etc/hadoop
export SPARK_MASTER_IP=0.0.0.0
export SPARK_MASTER_PORT=7077
export SPARK_MASTER_WEBUI_PORT=28080
export SPARK_WORKER_WEBUI_PORT=28081
export SPARK_WORKER_MEMORY=4g
export SPARK_WORKER_CORES=2
export SPARK_WORKER_INSTANCES=1
export SPARK_PID_DIR=/var/run

其中默认的8080和8081端口太容易冲突，建议修改下。

cp /opt/spark/conf/slaves.template /opt/spark/conf/slaves
vim /opt/spark/conf/slaves
修改ip

启动
先启动hadoop
/opt/spark/sbin/start-all.sh
/opt/spark/sbin/stop-all.sh

查看start-all.sh文件cat /opt/spark/sbin/start-all.sh
可以发现它加载了spark-config.sh配置文件，启动了集群master主节点和slaves子节点。

启动后webui地址 http://192.168.1.xxx:28080
