基于docker的spark-hadoop分布式集群之一： 环境搭建
一、软件准备
1、基础docker镜像：ubuntu，目前最新的版本是18
2、需准备的环境软件包：
(1) spark-2.3.0-bin-hadoop2.7.tgz
(2) hadoop-2.7.3.tar.gz
(3) apache-hive-2.3.2-bin.tar.gz
(4) jdk-8u101-linux-x64.tar.gz
(5) mysql-5.5.45-linux2.6-x86_64.tar.gz、mysql-connector-java-5.1.37-bin.jar
(6) scala-2.11.8.tgz
(7) zeppelin-0.8.0-bin-all.tgz
二、ubuntu镜像准备
1、获取官方的镜像：
docker pull ubuntu
2、因官方镜像中的apt源是国外资源，后续扩展安装软件包时较麻烦。先修改为国内源：
（1）启动ubuntu容器，并进入容器中的apt配置目录
docker run -it -d ubuntu
docker exec -it ubuntu /bin/bash
cd /etc/apt
（2）先将原有的源文件备份：
mv sources.list sources.list.bak
（3）换为国内源，这里提供阿里的资源。因官方的ubuntu没有艰装vi等软件，使用echo指令写入。需注意一点，资源必须与系统版本匹配。
echo deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse >> sources.list echo deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse >> sources.list echo deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse >> sources.list echo deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse >> sources.list echo deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse >> sources.list echo deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse >> sources.list echo deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse >> sources.list echo deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse >> sources.list echo deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse >> sources.list echo deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse >> sources.list
3、退出容器，提交镜像
exit docker commit 容器id ubuntu:latest
生成的ubuntu镜像，就可以做为基础镜像使用。
三、spark-hadoop集群配置
先前所准备的一列系软件包，在构建镜像时，直接用RUN ADD指令添加到镜像中，这里先将一些必要的配置处理好。这些配置文件，都来自于各个软件包中的conf目录下。
1、Spark配置
（1）spark-env.sh
声明Spark需要的环境变量
SPARK_MASTER_WEBUI_PORT=8888
export SPARK_HOME=$SPARK_HOME
export HADOOP_HOME=$HADOOP_HOME
export MASTER=spark://hadoop-maste:7077
export SCALA_HOME=$SCALA_HOME
export SPARK_MASTER_HOST=hadoop-maste
export JAVA_HOME=/usr/local/jdk1.8.0_101
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
（2）spark-default.conf
关于spark的默认配置
spark.executor.memory=2G spark.driver.memory=2G spark.executor.cores=2 #spark.sql.codegen.wholeStage=false #spark.memory.offHeap.enabled=true #spark.memory.offHeap.size=4G #spark.memory.fraction=0.9 #spark.memory.storageFraction=0.01 #spark.kryoserializer.buffer.max=64m #spark.shuffle.manager=sort #spark.sql.shuffle.partitions=600 spark.speculation=true spark.speculation.interval=5000 spark.speculation.quantile=0.9 spark.speculation.multiplier=2 spark.default.parallelism=1000 spark.driver.maxResultSize=1g #spark.rdd.compress=false spark.task.maxFailures=8 spark.network.timeout=300 spark.yarn.max.executor.failures=200 spark.shuffle.service.enabled=true spark.dynamicAllocation.enabled=true spark.dynamicAllocation.minExecutors=4 spark.dynamicAllocation.maxExecutors=8 spark.dynamicAllocation.executorIdleTimeout=60 #spark.serializer=org.apache.spark.serializer.JavaSerializer #spark.sql.adaptive.enabled=true #spark.sql.adaptive.shuffle.targetPostShuffleInputSize=100000000 #spark.sql.adaptive.minNumPostShufflePartitions=1 ##for spark2.0 #spark.sql.hive.verifyPartitionPath=true #spark.sql.warehouse.dir spark.sql.warehouse.dir=/spark/warehouse
（3）节点声明文件，包括masters文件及slaves文件
主节点声明文件：masters
hadoop-maste
从节点文件：slaves
hadoop-node1
hadoop-node2
2、Hadoop配置
（1）hadoop-env.sh
声明Hadoop需要的环境变量
export JAVA_HOME=/usr/local/jdk1.8.0_101
export HADOOP_CONF_DIR=${HADOOP_CONF_DIR:-"/etc/hadoop"}
for f in $HADOOP_HOME/contrib/capacity-scheduler/*.jar; do
if [ "$HADOOP_CLASSPATH" ]; then
export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$f
else
export HADOOP_CLASSPATH=$f
fi
done
export HADOOP_OPTS="$HADOOP_OPTS -Djava.net.preferIPv4Stack=true"
export HADOOP_NAMENODE_OPTS="-Dhadoop.security.logger=${HADOOP_SECURITY_LOGGER:-INFO,RFAS} -Dhdfs.audit.logger=${HDFS_AUDIT_LOGGER:-INFO,NullAppender} $HADOOP_NAMENODE_OPTS"
export HADOOP_DATANODE_OPTS="-Dhadoop.security.logger=ERROR,RFAS $HADOOP_DATANODE_OPTS"
export HADOOP_SECONDARYNAMENODE_OPTS="-Dhadoop.security.logger=${HADOOP_SECURITY_LOGGER:-INFO,RFAS} -Dhdfs.audit.logger=${HDFS_AUDIT_LOGGER:-INFO,NullAppender} $HADOOP_SECONDARYNAMENODE_OPTS"
export HADOOP_NFS3_OPTS="$HADOOP_NFS3_OPTS"
export HADOOP_PORTMAP_OPTS="-Xmx512m $HADOOP_PORTMAP_OPTS"
export HADOOP_CLIENT_OPTS="-Xmx512m $HADOOP_CLIENT_OPTS"
export HADOOP_SECURE_DN_USER=${HADOOP_SECURE_DN_USER}
export HADOOP_SECURE_DN_LOG_DIR=${HADOOP_LOG_DIR}/${HADOOP_HDFS_USER}
export HADOOP_PID_DIR=${HADOOP_PID_DIR}
export HADOOP_SECURE_DN_PID_DIR=${HADOOP_PID_DIR}
export HADOOP_IDENT_STRING=$USER
（2）hdfs-site.xml
主要设置了Hadoop的name及data节点。name节点存储的是元数据，data存储的是数据文件
<?xml version="1.0"?> <configuration> <property> <name>dfs.namenode.name.dir</name> <value>file:/usr/local/hadoop2.7/dfs/name</value> </property> <property> <name>dfs.datanode.data.dir</name> <value>file:/usr/local/hadoop2.7/dfs/data</value> </property> <property> <name>dfs.webhdfs.enabled</name> <value>true</value> </property> <property> <name>dfs.replication</name> <value>2</value> </property> <property> <name>dfs.permissions.enabled</name> <value>false</value> </property> </configuration>
（3）core-site.xml
设置主节点的地址：hadoop-maste。与后面启动容器时，设置的主节点hostname要一致。
<?xml version="1.0"?> <configuration> <property> <name>fs.defaultFS</name> <value>hdfs://hadoop-maste:9000/</value> </property> <property> <name>hadoop.tmp.dir</name> <value>file:/usr/local/hadoop/tmp</value> </property> <property> <name>hadoop.proxyuser.root.hosts</name> <value>*</value> </property> <property> <name>hadoop.proxyuser.root.groups</name> <value>*</value> </property> <property> <name>hadoop.proxyuser.oozie.hosts</name> <value>*</value> </property> <property> <name>hadoop.proxyuser.oozie.groups</name> <value>*</value> </property> </configuration>

（5）mapred-site.xml
<?xml version="1.0"?> <configuration> <property> <name>mapreduce.framework.name</name> <value>yarn</value> </property> <property> <name>mapreduce.jobhistory.address</name> <!-- 配置实际的Master主机名和端口--> <value>hadoop-maste:10020</value> </property> <property> <name>mapreduce.map.memory.mb</name> <value>4096</value> </property> <property> <name>mapreduce.reduce.memory.mb</name> <value>8192</value> </property> <property> <name>yarn.app.mapreduce.am.staging-dir</name> <value>/stage</value> </property> <property> <name>mapreduce.jobhistory.done-dir</name> <value>/mr-history/done</value> </property> <property> <name>mapreduce.jobhistory.intermediate-done-dir</name> <value>/mr-history/tmp</value> </property> </configuration>
（6）主节点声明文件：master
hadoop-maste
3、hive配置
（1）hive-site.xml
主要两个：一是hive.server2.transport.mode设为binary，使其支持JDBC连接；二是设置mysql的地址。

三、集群启动脚本
整套环境启动较为烦琐，这里将需要的操作写成脚本，在容器启动时，自动运行。
1、环境变量
先前在处理集群配置中，用到许多环境变量，这里统一做定义profile文件，构建容器时，用它替换系统的配置文件，即/etc/profile
profile文件：
if [ "$PS1" ]; then
if [ "$BASH" ] && [ "$BASH" != "/bin/sh" ]; then
# The file bash.bashrc already sets the default PS1.
# PS1='\h:\w\$ '
if [ -f /etc/bash.bashrc ]; then
. /etc/bash.bashrc
fi
else
if [ "`id -u`" -eq 0 ]; then
PS1='# '
else
PS1='$ '
fi
fi
fi
if [ -d /etc/profile.d ]; then
for i in /etc/profile.d/*.sh; do
if [ -r $i ]; then
. $i
fi
done
unset i
fi
export JAVA_HOME=/usr/local/jdk1.8.0_101
export SCALA_HOME=/usr/local/scala-2.11.8
export HADOOP_HOME=/usr/local/hadoop-2.7.3
export SPARK_HOME=/usr/local/spark-2.3.0-bin-hadoop2.7
export HIVE_HOME=/usr/local/apache-hive-2.3.2-bin
export MYSQL_HOME=/usr/local/mysql
export PATH=$HIVE_HOME/bin:$MYSQL_HOME/bin:$JAVA_HOME/bin:$SCALA_HOME/bin:$HADOOP_HOME/bin:$SPARK_HOME/bin:$PATH
2、SSH配置
各个容器需要通过网络端口连接在一起，为方便连接访问，使用SSH无验证登录
ssh_config文件：
Host localhost
StrictHostKeyChecking no
Host 0.0.0.0
StrictHostKeyChecking no
Host hadoop-*
StrictHostKeyChecking no
3、Hadoop集群脚本
（1）启动脚本：start-hadoop.sh
#!/bin/bash
echo -e "\n"
hdfs namenode -format -force
echo -e "\n"
$HADOOP_HOME/sbin/start-dfs.sh
echo -e "\n"
$HADOOP_HOME/sbin/start-yarn.sh
echo -e "\n"
$SPARK_HOME/sbin/start-all.sh
echo -e "\n"
hdfs dfs -mkdir /mr-history
hdfs dfs -mkdir /stage
echo -e "\n":
（2）重启脚本：restart-hadoop.sh
#!/bin/bash
echo -e "\n"
echo -e "\n"
$HADOOP_HOME/sbin/start-dfs.sh
echo -e "\n"
$HADOOP_HOME/sbin/start-yarn.sh
echo -e "\n"
$SPARK_HOME/sbin/start-all.sh
echo -e "\n"
hdfs dfs -mkdir /mr-history
hdfs dfs -mkdir /stage
echo -e "\n"
3、Mysql脚本
（1）mysql 初始化脚本：init_mysql.sh
#!/bin/bash
cd /usr/local/mysql/
echo ..........mysql_install_db --user=root.................
nohup ./scripts/mysql_install_db --user=root &
sleep 3
echo ..........mysqld_safe --user=root.................
nohup ./bin/mysqld_safe --user=root &
sleep 3
echo ..........mysqladmin -u root password 'root'.................
nohup ./bin/mysqladmin -u root password 'root' &
sleep 3
echo ..........mysqladmin -uroot -proot shutdown.................
nohup ./bin/mysqladmin -uroot -proot shutdown &
sleep 3
echo ..........mysqld_safe.................
nohup ./bin/mysqld_safe --user=root &
sleep 3
echo ...........................
nohup ./bin/mysql -uroot -proot -e "grant all privileges on *.* to root@'%' identified by 'root' with grant option;"
sleep 3
echo ........grant all privileges on *.* to root@'%' identified by 'root' with grant option...............
4、Hive脚本
（1）hive初始化：init_hive.sh
#!/bin/bash
cd /usr/local/apache-hive-2.3.2-bin/bin
sleep 3
nohup ./schematool -initSchema -dbType mysql &
sleep 3
nohup ./hive --service metastore &
sleep 3
nohup ./hive --service hiveserver2 &
sleep 5
echo Hive has initiallized!
四、镜像构建

（2）构建脚本：build.sh
echo build Spark-hadoop images
docker build -t="spark" .
（3）构建镜像，执行：
./build.sh
五、容器构建脚本
（1）创建子网
所有的网络，通过内网连接，这里构建一个名为spark的子网：build_network.sh
echo create network
docker network create --subnet=172.16.0.0/16 spark
echo create success
docker network ls
（2）容器启动脚本：start_container.sh
echo start hadoop-hive container...
docker run -itd --restart=always --net spark --ip 172.16.0.5 --privileged --name hive --hostname hadoop-hive --add-host hadoop-node1:172.16.0.3 --add-host hadoop-node2:172.16.0.4 --add-host hadoop-mysql:172.16.0.6 --add-host hadoop-maste:172.16.0.2 --add-host zeppelin:172.16.0.7 spark-lin /bin/bash
echo start hadoop-mysql container ...
docker run -itd --restart=always --net spark --ip 172.16.0.6 --privileged --name mysql --hostname hadoop-mysql --add-host hadoop-node1:172.16.0.3 --add-host hadoop-node2:172.16.0.4 --add-host hadoop-hive:172.16.0.5 --add-host hadoop-maste:172.16.0.2 --add-host zeppelin:172.16.0.7 spark-lin /bin/bash
echo start hadoop-maste container ...
docker run -itd --restart=always --net spark --ip 172.16.0.2 --privileged -p 18032:8032 -p 28080:18080 -p 29888:19888 -p 17077:7077 -p 51070:50070 -p 18888:8888 -p 19000:9000 -p 11100:11000 -p 51030:50030 -p 18050:8050 -p 18081:8081 -p 18900:8900 -p 18088:8088 --name hadoop-maste --hostname hadoop-maste --add-host hadoop-node1:172.16.0.3 --add-host hadoop-node2:172.16.0.4 --add-host hadoop-hive:172.16.0.5 --add-host hadoop-mysql:172.16.0.6 --add-host zeppelin:172.16.0.7 spark-lin /bin/bash
echo "start hadoop-node1 container..."
docker run -itd --restart=always --net spark --ip 172.16.0.3 --privileged -p 18042:8042 -p 51010:50010 -p 51020:50020 --name hadoop-node1 --hostname hadoop-node1 --add-host hadoop-hive:172.16.0.5 --add-host hadoop-mysql:172.16.0.6 --add-host hadoop-maste:172.16.0.2 --add-host hadoop-node2:172.16.0.4 --add-host zeppelin:172.16.0.7 spark-lin /bin/bash
echo "start hadoop-node2 container..."
docker run -itd --restart=always --net spark --ip 172.16.0.4 --privileged -p 18043:8042 -p 51011:50011 -p 51021:50021 --name hadoop-node2 --hostname hadoop-node2 --add-host hadoop-maste:172.16.0.2 --add-host hadoop-node1:172.16.0.3 --add-host hadoop-mysql:172.16.0.6 --add-host hadoop-hive:172.16.0.5 --add-host zeppelin:172.16.0.7 spark-lin /bin/bash
echo "start Zeppeline container..."
docker run -itd --restart=always --net spark --ip 172.16.0.7 --privileged -p 38080:18080 -p 38443:18443 --name zeppelin --hostname zeppelin --add-host hadoop-maste:172.16.0.2 --add-host hadoop-node1:172.16.0.3 --add-host hadoop-node2:172.16.0.4 --add-host hadoop-mysql:172.16.0.6 --add-host hadoop-hive:172.16.0.5 spark-lin /bin/bash
echo start sshd...
docker exec -it hadoop-maste /etc/init.d/ssh start
docker exec -it hadoop-node1 /etc/init.d/ssh start
docker exec -it hadoop-node2 /etc/init.d/ssh start
docker exec -it hive /etc/init.d/ssh start
docker exec -it mysql /etc/init.d/ssh start
docker exec -it zeppelin /etc/init.d/ssh start
echo start service...
docker exec -it mysql bash -c "sh ~/init_mysql.sh"
docker exec -it hadoop-maste bash -c "sh ~/start-hadoop.sh"
docker exec -it hive bash -c "sh ~/init_hive.sh"
docker exec -it zeppelin bash -c "$ZEPPELIN_HOME/bin/zeppelin-daemon.sh start"
echo finished
docker ps
（3）容器停止并移除：stop_container.sh
docker stop hadoop-maste
docker stop hadoop-node1
docker stop hadoop-node2
docker stop hive
docker stop mysql
docker stop zeppelin
echo stop containers
docker rm hadoop-maste
docker rm hadoop-node1
docker rm hadoop-node2
docker rm hive
docker rm mysql
docker rm zeppelin
echo rm containers
docker ps
六、运行测试
依次执行如下脚本：
1、创建子网
./build_network.sh
2、启动容器
./start_container.sh
3、进入主节点：
docker exec -it hadoop-maste /bin/bash
jps一下，进程是正常的
4、访问集群子节点
ssh hadoop-node2
一样可以看到，与主节点类似的进程信息
说明集群已经是搭建起来。
5、Spark测试
访问：http://localhost:38080
进入Zeppelin交互界面，新建一个note，使用Spark为默认的解释器
import org.apache.commons.io.IOUtils import java.net.URL import java.nio.charset.Charset // Zeppelin creates and injects sc (SparkContext) and sqlContext (HiveContext or SqlContext) // So you don't need create them manually // load bank data val bankText = sc.parallelize( IOUtils.toString( new URL("http://emr-sample-projects.oss-cn-hangzhou.aliyuncs.com/bank.csv"), Charset.forName("utf8")).split("\n")) case class Bank(age: Integer, job: String, marital: String, education: String, balance: Integer) val bank = bankText.map(s => s.split(";")).filter(s => s(0) != "\"age\"").map( s => Bank(s(0).toInt, s(1).replaceAll("\"", ""), s(2).replaceAll("\"", ""), s(3).replaceAll("\"", ""), s(5).replaceAll("\"", "").toInt ) ).toDF() bank.registerTempTable("bank")
可视化报表，如下图：
说明Spark已经是成功运行。
下一章，将对本套环境各个模块做测试。
OVER！
