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>

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

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 "
"

hdfs namenode -format -force

echo -e "
"

$HADOOP_HOME/sbin/start-dfs.sh

echo -e "
"

$HADOOP_HOME/sbin/start-yarn.sh

echo -e "
"

$SPARK_HOME/sbin/start-all.sh

echo -e "
"

hdfs dfs -mkdir /mr-history

hdfs dfs -mkdir /stage


echo -e "
":

（2）重启脚本：restart-hadoop.sh

#!/bin/bash
echo -e "
"

echo -e "
"

$HADOOP_HOME/sbin/start-dfs.sh

echo -e "
"

$HADOOP_HOME/sbin/start-yarn.sh

echo -e "
"

$SPARK_HOME/sbin/start-all.sh

echo -e "
"

hdfs dfs -mkdir /mr-history

hdfs dfs -mkdir /stage


echo -e "
"

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("
"))

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。
