- 解压
tar xzvf jdk-8u301-linux-x64.tar.gz -C ../software/
- 配置环境变量：
vim ~/.profile，输入：
JAVA_HOME=/root/***/software/jdk1.8.0_301
PATH=$PATH:$JAVA_HOME/bin

source ~/.profile - 验证安装：
java -version，出现以下信息说明安装成功：

安装scala
- 下载
wget https://downloads.lightbend.com/scala/2.11.8/scala-2.11.8.tgz
- 解压
tar xzvf scala-2.11.8.tgz -C ../software/
- 配置环境变量：
vim ~/.profile，输入：
SCALA_HOME=/root/***/software/scala-2.11.8
PATH=$PATH:$SCALA_HOME/bin
- 环境变量生效
source ~/.profile - 验证安装：
scala，出现以下信息说明安装成功，:q退出：
Welcome to Scala 2.11.8 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_301).
Type in expressions for evaluation. Or try :help.
安装spark
- 下载
wget https://archive.apache.org/dist/spark/spark-2.4.8/spark-2.4.8-bin-hadoop2.7.tgz
- 解压
tar xzvf spark-2.4.8-bin-hadoop2.7.tgz -C ../software/
- 配置环境变量：
vim ~/.profile，输入：
SPARK_HOME=/root/***/software/spark-2.4.8-bin-hadoop2.7
PATH=$PATH:$SPARK_HOME/bin
- 环境变量生效
source ~/.profile - 验证安装：
spark-shell，出现以下信息说明安装成功，:q退出：

2. Standalone模式
- 机器信息如下：
| hostname | role |
|---|---|
| bigdata112 | master |
| bigdata113 | worker |
| bigdata114 | worker |
| bigdata115 | worker |
- 在Local模式基础上（当前机器：bigdata112）：
cd ../software/spark-2.4.8-bin-hadoop2.7/conf/
cp spark-env.sh.template spark-env.sh
vim spark-env.sh
export JAVA_HOME=/root/***/software/jdk1.8.0_301
export SCALA_HOME=/root/***/software/scala-2.11.8
export SPARK_HOME=/root/***/software/spark-2.4.8-bin-hadoop2.7
export SPARK_EXECUTOR_MEMORY=5G
export SPARK_EXECUTOR_cores=2
export SPARK_WORKER_CORES=2
cp slaves.template slaves
vim slaves
bigdata113
bigdata114
bigdata115
- 将spark目录复制到其他机器上（注意环境变量也要保持一致）
scp /root/***/software/spark-2.4.8-bin-hadoop2.7 bigdata113:/root/***/software/
scp /root/***/software/spark-2.4.8-bin-hadoop2.7 bigdata114:/root/***/software/
scp /root/***/software/spark-2.4.8-bin-hadoop2.7 bigdata115:/root/***/software/
- 启动master（webUI端口默认是8080）：
./root/***/software/spark-2.4.8-bin-hadoop2.7/sbin/start-master.sh
starting org.apache.spark.deploy.master.Master, logging to /root/***/software/spark-2.4.8-bin-hadoop2.7/logs/spark-root-org.apache.spark.deploy.master.Master-1-***2021.out

- 启动salves（webUI端口默认是8080）：
./root/***/software/spark-2.4.8-bin-hadoop2.7/sbin/start-slaves.sh
bigdata113: starting org.apache.spark.deploy.worker.Worker, logging to /root/***/software/spark-2.4.8-bin-hadoop2.7/logs/spark-root-org.apache.spark.deploy.worker.Worker-1-***2021.out
bigdata114: starting org.apache.spark.deploy.worker.Worker, logging to /root/***/software/spark-2.4.8-bin-hadoop2.7/logs/spark-root-org.apache.spark.deploy.worker.Worker-2-***2021.out
bigdata115: starting org.apache.spark.deploy.worker.Worker, logging to /root/***/software/spark-2.4.8-bin-hadoop2.7/logs/spark-root-org.apache.spark.deploy.worker.Worker-3-***2021.out
图片.png
- 执行
spark-shell --master spark://***2021:7077就能看到master = spark://***2021:7077的信息
Spark context available as 'sc' (master = spark://***2021:7077, app id = app-20210909163213-0001).
Spark On Yarn模式
- hadoop/yarn安装见我的另一个博客：Hadoop三种模式的安装与配置
- 基于Standalone模式基础，在spark-env.sh中添加hadoop和yarn的配置文件位置信息
HADOOP_CONF_DIR=/root/***/software/hadoop-2.7.6/etc/hadoop
YARN_CONF_DIR=/root/***/software/hadoop-2.7.6/etc/hadoop
- 将spark-env.sh文件复制到其他机器
- 启动hadoop、yarn（无需启动spark的Master和slaves，因为它两将由yarn管理启动）
- 执行
spark-shell --master yarn --deploy-mode client就能看到master = yarn的信息
Spark context available as 'sc' (master = yarn, app id = application_1560334779290_0001).
