大数据本地环境搭建03-Spark搭建

需要提前部署好 Zookeeper/Hadoop/Hive 环境

1 Local模式

1.1 上传压缩包

下载链接

链接：https://pan.baidu.com/s/1rLq39ddxh7np7JKiuRAhDA?pwd=e20h
提取码：e20h

将spark-3.1.2-bin-hadoop3.2.tar.gz压缩包到node1下的/export/server目录

1.2 解压压缩包

tar -zxvf /export/server/spark-3.1.2-bin-hadoop3.2.tgz -C /export/server/

1.3 修改权限

如果有权限问题，可以修改为root，方便学习时操作，实际中使用运维分配的用户和权限即可

chown -R root /export/server/spark-3.1.2-bin-hadoop3.2 
chgrp -R root /export/server/spark-3.1.2-bin-hadoop3.2 

1.4 修改文件名

mv /export/server/spark-3.1.2-bin-hadoop3.2 /export/server/spark

1.5 将spark添加到环境变量

echo 'export SPARK_HOME=/export/server/spark' >> /etc/profile
echo 'export PATH=$PATH:$SPARK_HOME/bin:$SPARK_HOME/sbin' >> /etc/profile
source /etc/profile

1.6 启动测试

spark-shell

2 Standalone模式

2.1 配置node1中的workers服务

# 进入配置目录
cd /export/server/spark/conf
# 修改配置文件名称
mv workers.template workers
# 将三台机器写入workers
echo 'node1' > workers
echo 'node2' >> workers
echo 'node3' >> workers

2.2 配置spark中的环境变量

cd /export/server/spark/conf
## 修改配置文件名称
mv spark-env.sh.template spark-env.sh
## 修改配置文件
## 设置JAVA安装目录,jdk1.8.0_65 看自己的java目录和版本填写
echo 'JAVA_HOME=/export/server/jdk1.8.0_65' >> spark-env.sh
## 设置python安装目录
echo 'PYSPARK_PYTHON=/export/server/python3/bin/python3' >> spark-env.sh
## HADOOP软件配置文件目录，读取HDFS上文件
echo 'HADOOP_CONF_DIR=/export/server/hadoop-3.3.0/etc/hadoop' >> spark-env.sh
## 指定spark老大Master的IP和提交任务的通信端口
echo 'SPARK_MASTER_HOST=node1' >> spark-env.sh
echo 'SPARK_MASTER_PORT=7077' >> spark-env.sh
echo 'SPARK_MASTER_WEBUI_PORT=8080' >> spark-env.sh
echo 'SPARK_WORKER_CORES=1' >> spark-env.sh
echo 'SPARK_WORKER_MEMORY=1g' >> spark-env.sh
echo 'SPARK_WORKER_PORT=7078' >> spark-env.sh
echo 'SPARK_WORKER_WEBUI_PORT=8081' >> spark-env.sh
## 历史日志服务器
echo 'SPARK_HISTORY_OPTS="-Dspark.history.fs.logDirectory=hdfs://node1:8020/sparklog/ -Dspark.history.fs.cleaner.enabled=true"' >> spark-env.sh

2.3 创建EventLogs存储目录

启动HDFS服务，创建应用运行事件日志目录

hdfs dfs -mkdir -p /sparklog/
hdfs dfs -chown hadoop:root /sparklog
hdfs dfs -chmod 775 /sparklog

2.4 配置Spark应用保存EventLogs

## 进入配置目录
cd /export/server/spark/conf
## 修改配置文件名称
mv spark-defaults.conf.template spark-defaults.conf
## 添加内容如下：
echo 'spark.eventLog.enabled 	true' >> spark-defaults.conf
echo 'spark.eventLog.dir	 hdfs://node1:8020/sparklog/' >> spark-defaults.conf
echo 'spark.eventLog.compress 	true' >> spark-defaults.conf

2.5 设置日志级别

## 进入目录
cd /export/server/spark/conf
## 修改日志属性配置文件名称
mv log4j.properties.template log4j.properties
## 改变日志级别
sed -i "1,25s/INFO/WARN/"  /export/server/spark/conf/log4j.properties

2.6 修改启动文件

避免和hadopp的启动文件名字冲突

mv /export/server/spark/sbin/stop-all.sh /export/server/spark/sbin/stop-all-spark.sh
mv /export/server/spark/sbin/start-all.sh /export/server/spark/sbin/start-all-spark.sh

2.7 拷贝spark到node2和node3

scp -r /export/server/spark node2:/export/server/
scp -r /export/server/spark node3:/export/server/

2.8 拷贝python到node2和node3

scp -r /export/server/python3 node2:/export/server/
scp -r /export/server/python3 node3:/export/server/

2.9 拷贝环境变量文件到node2和node3

scp /etc/profile node2:/etc/
scp /etc/profile node3:/etc/

2.10 服务启动

• 集群启动,在node1上执行

# 启动spark
start-all-spark.sh
# 启动历史服务
start-history-server.sh

2.11 测试

• 使用pyspark连接

spark-shell --master spark://node1:7077

2.12 Web访问

http://node1:8080

3 Standalone高可用

3.1 关闭集群服务

stop-all-spark.sh 

3.2 在node1上进行配置

将/export/server/spark/conf/spark-env.sh文件中的SPARK_MASTER_HOST注释
# SPARK_MASTER_HOST=node1


echo 'SPARK_DAEMON_JAVA_OPTS="-Dspark.deploy.recoveryMode=ZOOKEEPER -Dspark.deploy.zookeeper.url=node1:2181,node2:2181,node3:2181 -Dspark.deploy.zookeeper.dir=/spark-ha"' >> /export/server/spark/conf/spark-env.sh

3.3 将node1的配置文件进行分发

cd /export/server/spark/conf
scp -r spark-env.sh node2:$PWD
scp -r spark-env.sh node3:$PWD

3.4 三台机器启动集群上的zk服务

zkServer.sh start

3.5 在HDFS上创建高可用日志目录

hadoop fs -mkdir /spark-ha

3.6 node1上启动spark集群

start-all-spark.sh

3.7 在node2上启动master

start-master.sh

3.8 web验证

http://node1:8080
node2:8080

4 Python安装

4.1 上传安装包

链接：https://pan.baidu.com/s/1LkpjREnLXLzebki4VTz1Ag?pwd=6bs5
提取码：6bs5

将python3.tar.gz压缩包到node1下的/export/server目录

4.2 解压安装包

tar -zxvf /export/server/python3.tar.gz -C /export/server

4.3 将Python添加到环境变量

echo 'export PYTHON_HOME=/export/server/python3' >> /etc/profile
echo 'export PATH=$PATH:$PYTHON_HOME/bin' >> /etc/profile
source /etc/profile

4.4 拷贝python到node2和node3

scp -r /export/server/python3 node2:/export/server/
scp -r /export/server/python3 node3:/export/server/

4.5 启动测试

pyspark

5 Pysaprk的安装

当前spark依赖的版本为3.1.2

5.1 在线安装
