通过 docker-compose 快速部署 Hadoop 集群详细教程

一、概述

docker-compose 项目是docker官方的开源项目， 负责实现对docker容器集群的快速编排，来轻松高效的管理容器，定义运行多个容器。

  • 通过docker-compose来部署应用是非常简单和快捷的。但是因为docker-compose是管理单机的，所以一般通过docker-compose部署的应用用于测试、poc环境以及学习等非生产环境场景。生产环境如果需要使用容器化部署，建议还是使用K8s。

  • Hadoop集群部署还是稍微比较麻烦点的，针对小伙伴能够快速使用Hadoop集群，这里就使用docker-compose来部署Hadoop集群。

关于docker-compose介绍可以参考我以下几篇文章：

  • Docker三剑客之Compose
  • docker-compose 进阶篇

如果需要通过k8s来部署Hadoop环境，可以参考我之前的以下几篇文章：

  • 【云原生】Hadoop on k8s 环境部署
  • 【云原生】Hadoop HA on k8s 环境部署

Hadoop NameNode HA 架构： Hadoop YARN HA 架构：

二、安装 docker 和 docker-compose

1）安装 docker

# 安装yum-config-manager配置工具
yum -y install yum-utils
# 建议使用阿里云yum源：（推荐）
#yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# 安装docker-ce版本
yum install -y docker-ce
# 启动并开机启动
systemctl enable --now docker
docker --version

2）安装 docker-compose

官方安装地址教程：docs.docker.com/compose/ins…

curl -SL https://github.com/docker/compose/releases/download/v2.16.0/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker-compose --version

三、docker-compose deploy

在讲Hadoop之前这里先补充几个重要的知识点，其实在k8s里面也讲过，只是这里正对docker-compose再来讲解一次。

1）设置副本数

replicas_test.yaml

version: '3'
services:
  replicas_test:
    image: registry.cn-hangzhou.aliyuncs.com/bigdata_cloudnative/centos:7.7.1908
    restart: always
    command: ["sh","-c","sleep 36000"]
    deploy:
      replicas: 2
    healthcheck:
      test: ["CMD-SHELL", "hostname"]
      interval: 10s
      timeout: 5s
      retries: 3

执行

docker-compose -f replicas_test.yaml up -d
docker-compose -f replicas_test.yaml ps

从上图可知，通过配置 deploy.replicas 来控制创建服务容器的数量，但是并非所有场景都适用，下面Hadoop的有些组件是不适用的，像要求设置主机名和容器名的时候，就不太适用通过这个参数来调整容器的数量。

2）资源隔离

docker-compose的资源隔离跟k8s里面的是一样的，所以通过下面示例就很好理解了，示例如下：

resources_test.yaml

version: '3'
services:
  resources_test:
    image: registry.cn-hangzhou.aliyuncs.com/bigdata_cloudnative/centos:7.7.1908
    restart: always
    command: ["sh","-c","sleep 36000"]
    deploy:
      replicas: 2
      resources:
        # 容器资源申请的最大值，容器最多能适用这么多资源
        limits:
          cpus: '1'
          memory: 100M
        # 所需资源的最小值，跟k8s里的requests一样，就是运行容器的最小值
        reservations:
          cpus: '0.5'
          memory: 50M
    healthcheck:
      test: ["CMD-SHELL", "hostname"]
      interval: 10s
      timeout: 5s
      retries: 3

执行

docker-compose -f resources_test.yaml up -d
docker-compose -f resources_test.yaml ps
# 查看状态
docker stats deploy-test-resources_test-1

四、docker-compose network

network 在容器中是非常重要的一个知识点，所以这里重点以示例讲解的方式来看看不同docker-compose项目之间如果通过名称访问，默认清楚下，每个docker-compose就是一个项目（不同目录，相同目录的多个compose属于一个项目），每个项目就会默认生成一个网络。注意，默认情况下只能在同一个网络中使用名称相互访问。那不同项目中如何通过名称访问呢，接下来就一示例讲解。

test1/test1.yaml

version: '3'
services:
  test1:
    image: registry.cn-hangzhou.aliyuncs.com/bigdata_cloudnative/centos:7.7.1908
    container_name: c_test1
    hostname: h_test1
    restart: always
    command: ["sh","-c","sleep 36000"]
    healthcheck:
      test: ["CMD-SHELL", "hostname"]
      interval: 10s
      timeout: 5s
      retries: 3

test2/test2.yaml

version: '3'
services:
  test2:
    image: registry.cn-hangzhou.aliyuncs.com/bigdata_cloudnative/centos:7.7.1908
    container_name: c_test2
    hostname: h_test2
    restart: always
    command: ["sh","-c","sleep 36000"]
    healthcheck:
      test: ["CMD-SHELL", "hostname"]
      interval: 10s
      timeout: 5s
      retries: 3

执行验证结果如下：

docker-compose -f test1/test1.yaml up -d
docker-compose -f test2/test2.yaml up -d
# 查看network，会生成两个network，如果两个yaml文件在同一个目录下，只会生成一个，它们也就属于同一个network下，是可以通过名称相互访问的。这里是在不同的目录下，就会生成两个network，默认情况下，不同的network是隔离的，不能通过名称访问的。yaml文件所在的目录名就是项目名称。这个项目名称是可以通过参数指定的，下面会细讲。
docker network ls
# 互ping
docker exec -it c_test1 ping c_test2
docker exec -it c_test1 ping h_test2
docker exec -it c_test2 ping c_test1
docker exec -it c_test2 ping h_test1
# 卸载
docker-compose -f test1/test1.yaml down
docker-compose -f test2/test2.yaml down

接下来我们加上network再进行测试验证

  • test1/network_test1.yaml

在 test1/network_test1.yaml 定义创建新network，在下面test2/network_test2.yaml引用test1创建的网络，那么这两个项目就在同一个网络中了，注意先后执行顺序。

version: '3'
services:
  network_test1:
    image: registry.cn-hangzhou.aliyuncs.com/bigdata_cloudnative/centos:7.7.1908
    container_name: c_network_test1
    hostname: h_network_test1
    restart: always
    command: ["sh","-c","sleep 36000"]
    # 使用network
    networks:
      - test1_network
    healthcheck:
      test: ["CMD-SHELL", "hostname"]
      interval: 10s
      timeout: 5s
      retries: 3
# 定义创建新网络
networks:
  test1_network:
    driver: bridge
  • test2/network_test2.yaml
version: '3'
services:
  network_test2:
    image: registry.cn-hangzhou.aliyuncs.com/bigdata_cloudnative/centos:7.7.1908
    container_name: c_network_test2
    hostname: h_network_test2
    restart: always
    networks:
      - test1_network
    command: ["sh","-c","sleep 36000"]
    healthcheck:
      test: ["CMD-SHELL", "hostname"]
      interval: 10s
      timeout: 5s
      retries: 3
# 引用test1的网络
networks:
  # 项目名_网络名，可以通过docker network ls查看network名称
  test1_test1_network:
    external: true

执行验证结果如下：

docker-compose -f test1/network_test1.yaml up -d
docker-compose -f test2/network_test2.yaml up -d
# 查看网络
docker network ls
# 互ping
docker exec -it c_network_test1 ping -c3 c_network_test2 
docker exec -it c_network_test1 ping -c3 h_network_test2
docker exec -it c_network_test2 ping -c3 c_network_test1
docker exec -it c_network_test2 ping -c3 h_network_test1
# 卸载，注意顺序，要先卸载应用方，要不然network被应用了是删除不了的
docker-compose -f test2/network_test2.yaml down
docker-compose -f test1/network_test1.yaml down

从上实验可知，只有多个项目在同一个网络里才可以通过主机名或着容器名访问的。

五、docker-compose 项目

默认的项目名称就是当前yaml文件所在的目录名称，上面讲解network的时候生成的网络名称也会最前面的项目名称，但是项目名称是可以自定义的，示例讲解如下：

# test.yaml
version: '3'
services:
  test:
    image: registry.cn-hangzhou.aliyuncs.com/bigdata_cloudnative/centos:7.7.1908
    restart: always
    command: ["sh","-c","sleep 36000"]
    healthcheck:
      test: ["CMD-SHELL", "hostname"]
      interval: 10s
      timeout: 5s
      retries: 3

执行

# 先不加参数
docker-compose -f test.yaml up -d
# 查看网络
network ls
# 使用参数自定义项目名称，-p, --project-name，有四种写法
docker-compose -p=p001 -f test.yaml up -d
docker-compose -p p002 -f test.yaml up -d
docker-compose --project-name=p003 -f test.yaml up -d
docker-compose --project-name p004 -f test.yaml up -d
# 查看网络
docker network ls
# 查看所有项目
docker-compose ls

六、Hadoop 部署（非高可用）

1）安装 JDK

# jdk包在我下面提供的资源包里，当然你也可以去官网下载。
tar -xf jdk-8u212-linux-x64.tar.gz
# /etc/profile文件中追加如下内容：
echo "export JAVA_HOME=`pwd`/jdk1.8.0_212" >> /etc/profile
echo "export PATH=\$JAVA_HOME/bin:\$PATH" >> /etc/profile
echo "export CLASSPATH=.:\$JAVA_HOME/lib/dt.jar:\$JAVA_HOME/lib/tools.jar" >> /etc/profile
# 加载生效
source /etc/profile

2）下载 hadoop 相关的软件

### 1、Hadoop

docker build -t hadoop:v1 . --no-cache
# 为了方便小伙伴下载即可使用，我这里将镜像文件推送到阿里云的镜像仓库
docker tag hadoop:v1 registry.cn-hangzhou.aliyuncs.com/bigdata_cloudnative/hadoop:v1
docker push registry.cn-hangzhou.aliyuncs.com/bigdata_cloudnative/hadoop:v1
### 参数解释
# -t：指定镜像名称
# . ：当前目录Dockerfile
# -f：指定Dockerfile路径
#  --no-cache：不缓存

4）配置

配置文件会统一放在最下面提供的资源包里的。

1、Hadoop 配置

主要有以下几个文件：core-site.xml、dfs.hosts、dfs.hosts.exclude、hdfs-site.xml、mapred-site.xml、yarn-hosts-exclude、yarn-hosts-include、yarn-site.xml

2、Hive 配置

主要有以下几个文件：hive-env.sh、hive-site.xml，这篇文章不会讲hive部分，会放到下篇文章讲解。

5）启动脚本 bootstrap.sh

# bootstrap.sh
#!/usr/bin/env sh
wait_for() {
    echo Waiting for $1 to listen on $2...
    while ! nc -z $1 $2; do echo waiting...; sleep 1s; done
}
start_hdfs_namenode() {
        if [ ! -f /tmp/namenode-formated ];then
                ${HADOOP_HOME}/bin/hdfs namenode -format >/tmp/namenode-formated
        fi
        ${HADOOP_HOME}/bin/hdfs --loglevel INFO --daemon start namenode
        tail -f ${HADOOP_HOME}/logs/*namenode*.log
}
start_hdfs_datanode() {
        wait_for $1 $2

        tail -f ${HADOOP_HOME}/logs/*proxyserver*.log
}
start_mr_historyserver() {
        wait_for $1 $2
        ${HADOOP_HOME}/bin/mapred --loglevel INFO  --daemon  start historyserver
        tail -f ${HADOOP_HOME}/logs/*historyserver*.log
}
case $1 in
        hadoop-hdfs-nn)
                start_hdfs_namenode
                ;;
        hadoop-hdfs-dn)

                ;;
        *)
                echo "请输入正确的服务启动命令~"
        ;;
esac

【温馨提示】

  • 如果是不同的compose文件生成的容器，如果不指定一样的network，它们直接是不能通过主机名访问的。
  • depends_on 只能决定容器的启动先后顺序，无法决定容器里服务的启动顺序，作用不大，所以在上面 bootstrap.sh 脚本里加上一个 wait_for 函数来真正控制服务的启动顺序。

7）启动服务

# 这里-f docker-compose.yaml可以省略，如果文件名不是docker-compose.yaml就不能省略，-d 后台执行
docker-compose -f docker-compose.yaml up -d
# 查看状态
docker-compose -f docker-compose.yaml ps

8）测试验证

HDFS：http://ip:30070/

YARN：http://ip:30070/ docker-compose部署非高可用的Hadoop的详细部署就先到这里了，下面继续把高可用的环境部署。

七、Hadoop HA 部署（高可用）

1）安装 JDK

# jdk包在我下面提供的资源包里，当然你也可以去官网下载。
tar -xf jdk-8u212-linux-x64.tar.gz
# /etc/profile文件中追加如下内容：
echo "export JAVA_HOME=`pwd`/jdk1.8.0_212" >> /etc/profile
echo "export PATH=\$JAVA_HOME/bin:\$PATH" >> /etc/profile
echo "export CLASSPATH=.:\$JAVA_HOME/lib/dt.jar:\$JAVA_HOME/lib/tools.jar" >> /etc/profile
# 加载生效
source /etc/profile

2）下载 hadoop 相关的软件

### 1、zookeeper
# 下载地址：https://zookeeper.apache.org/releases.html
# zookeeper非高可用用不到
wget https://dlcdn.apache.org/zookeeper/zookeeper-3.8.0/apache-zookeeper-3.8.0-bin.tar.gz --no-check-certificate
tar -xf  apache-zookeeper-3.8.0-bin.tar.gz
### 2、Hadoop
# 下载地址：https://dlcdn.apache.org/hadoop/common/
wget https://dlcdn.apache.org/hadoop/common/hadoop-3.3.5/hadoop-3.3.5.tar.gz --no-check-certificate
### 3、spark
# Spark下载地址：http://spark.apache.org/downloads.html
wget https://dlcdn.apache.org/spark/spark-3.3.2/spark-3.3.2-bin-hadoop3.tgz --no-check-certificate
### 4、flink
wget https://dlcdn.apache.org/flink/flink-1.17.0/flink-1.17.0-bin-scala_2.12.tgz --no-check-certificate

3）构建镜像 Dockerfile

FROM registry.cn-hangzhou.aliyuncs.com/bigdata_cloudnative/centos:7.7.1908
RUN rm -f /etc/localtime && ln -sv /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo "Asia/Shanghai" > /etc/timezone

RUN groupadd --system --gid=10000 hadoop && useradd --system --home-dir /home/hadoop --uid=10000 --gid=hadoop hadoop
# 安装sudo
RUN yum -y install sudo ; chmod 640 /etc/sudoers
# 给hadoop添加sudo权限
RUN echo "hadoop ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers
RUN yum -y install install net-tools telnet wget
RUN mkdir /opt/apache/

COPY bootstrap.sh /opt/apache/
COPY config/hadoop-config/* ${HADOOP_HOME}/etc/hadoop/
RUN chown -R hadoop:hadoop /opt/apache
ENV ll "ls -l"
WORKDIR /opt/apache

开始构建镜像

docker build -t hadoop-ha:v1 . --no-cache
# 为了方便小伙伴下载即可使用，我这里将镜像文件推送到阿里云的镜像仓库
docker tag hadoop:v1 registry.cn-hangzhou.aliyuncs.com/bigdata_cloudnative/hadoop-ha:v1
docker push registry.cn-hangzhou.aliyuncs.com/bigdata_cloudnative/hadoop-ha:v1
### 参数解释
# -t：指定镜像名称
# . ：当前目录Dockerfile
# -f：指定Dockerfile路径
#  --no-cache：不缓存

4）配置

配置文件会统一放在最下面提供的资源包里的。

1、Hadoop 配置

主要有以下几个文件：core-site.xml、dfs.hosts、dfs.hosts.exclude、hdfs-site.xml、mapred-site.xml、yarn-hosts-exclude、yarn-hosts-include、yarn-site.xml

2、Hive 配置

主要有以下几个文件：hive-env.sh、hive-site.xml，这篇文章不会讲hive部分，会放到下篇文章讲解。

5）启动脚本 bootstrap.sh

7）启动服务

# 这里-f docker-compose.yaml可以省略，如果文件名不是docker-compose.yaml就不能省略，-d 后台执行
docker-compose -f docker-compose.yaml up -d
# 查看状态
docker-compose -f docker-compose.yaml ps

8）测试验证

HDFS：http://ip:30070 、http://ip:30071

namenode主节点： namenode备节点： databnode 节点： 通过命令行测试验证：

# 随便登录一个容器即可
docker exec -it hadoop-hdfs-jn-0 bash
hdfs dfs -ls /
hdfs dfs -touchz /test
hdfs dfs -mkdir /test123
hdfs dfs -ls /

YARN：http://ip:30888、http://ip:30889

resourcemanager 主节点： resourcemanager 备节点： nodemanager 节点：

git 地址：gitee.com/hadoop-bigd…
