docker安装cdh6.3.2集群（联网版）

一、前言

本次采用的在线安装方式，cdh为6.3.2版本，系统为centos7.4， docker节点可以为任意多个，下文将以3个docker容器为示例进行展示。此方法也可用在docker swarm上，docker容器能够互连，网络互通即可。

二、基础系统镜像制作

说明：此步在安装完docker后进行操作，步骤位置放的不对！！！

因为dockerhub上提供的centos系统为精简系统，使用时会缺少一些组件，制作一个centos7的基础镜像，Dockerfile为：

FROM docker.io/ansible/centos7-ansible
RUN yum -y install openssh-server
RUN yum -y install bind-utils
RUN yum -y install which
RUN yum -y install sudo

在Dockerfile同级目录执行:

docker build -t centos7-cdh .

生成要用的基础centos7的镜像。

三、宿主机初始化

以下在docker的宿主机上进行操作。

3.1配置yum源

yum install -y wget \
&& mkdir -p /etc/yum.repos.d/repo_bak \
&& mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/repo_bak/ \
&& wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo \
&& wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo \
&& yum clean all \
&& yum makecache \
&& yum update –y

3.2安装docker-ce

yum install -y yum-utils device-mapper-persistent-data lvm2 \
&& yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo\
&& yum makecache fast \
&& yum -y install docker-ce \
&& yum clean all \
&& docker version

3.3配置docker

data-root：docker根目录路径
insecure-registries：docker私有仓库地址
registry-mirrors：公共镜像仓库加速地址

mkdir -p /etc/docker/ && \
(
cat <<EOF
{
  "data-root":"/home/docker",
  "registry-mirrors": ["https://1e7waog4.mirror.aliyuncs.com"]
}
EOF
) >>/etc/docker/daemon.json \
&& systemctl start docker \
&& systemctl enable docker \
&& cat /etc/docker/daemon.json \
&& docker version

安装docker命令补全工具

yum install -y bash-completion \
&& source /usr/share/bash-completion/completions/docker \
&& source /usr/share/bash-completion/bash_completion \
&& yum clean all

3.4安装基本工具

yum install -y vim wget ntp net-tools \
&& yum clean all

3.5关闭防火墙

systemctl stop firewalld \
&& systemctl disable firewalld \
&& systemctl status firewalld

3.6设置SELinux模式

setenforce 0 \
|| sed -i 's/enforcing/disabled/g' /etc/selinux/config \
&& sed -i 's/permissive/disabled/g' /etc/selinux/config \
&& getenforce

3.7配置时间同步

vim /etc/ntp.conf

将时钟服务器更改为如下4个

server 0.cn.pool.ntp.org
server 1.cn.pool.ntp.org
server 2.cn.pool.ntp.org       
server 3.cn.pool.ntp.org

注意：若为离线安装，则要将服务器地址改为内网时间服务器地址。

启动设置ntp服务

systemctl start ntpd \
&& systemctl enable ntpd \
&& ntpdate -u 0.cn.pool.ntp.org \
&& hwclock --systohc \
&& date

3.8 创建自定义网络

docker network create --subnet=172.10.0.0/16 hadoop_net \
&& docker network ls

3.9启动容器

docker run -d \
--add-host cm.hadoop:172.10.0.2 \
--net hadoop_net \
--ip 172.10.0.2 \
-h cm.hadoop \
-p 10022:22 \
-p 7180:7180 \
--restart always \
--name cm.hadoop \
--privileged \
centos7-cdh \
/usr/sbin/init \
&& docker ps

四、容器安装ClouderaManager

4.1初始化环境

进入第三步创建的容器中，并将root的登录密码改为root

docker exec –it {dockerId} /bin/bash
su root
passwd
root
root

安装基础环境

yum install -y kde-l10n-Chinese telnet reinstall glibc-common vim wget ntp net-tools \
&& yum clean all

4.2配置中文环境变量

(
cat <<EOF
export LC_ALL=zh_CN.utf8
export LANG=zh_CN.utf8
export LANGUAGE=zh_CN.utf8
EOF
) >> ~/.bashrc \
&& localedef -c -f UTF-8 -i zh_CN zh_CN.utf8 \
&& source ~/.bashrc \
&& echo $LANG

4.3设置NTP时间同步服务

vim /etc/ntp.conf

更改为以下四个时钟服务器

server 0.cn.pool.ntp.org
server 1.cn.pool.ntp.org
server 2.cn.pool.ntp.org       
server 3.cn.pool.ntp.org

启动ntp服务

systemctl start ntpd && \
systemctl enable ntpd && \
ntpdate -u 0.cn.pool.ntp.org && \
hwclock --systohc && \
date

4.4准备MySQL安装包(采用docker独立安装跳过此步)

mkdir -p /root/hadoop_CHD/mysql \
&& wget -O /root/hadoop_CHD/mysql/mysql-5.7.27-1.el7.x86_64.rpm-bundle.tar \
https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.27-1.el7.x86_64.rpm-bundle.tar \
&& ls /root/hadoop_CHD/mysql

说明：

1、通过wget下载mysql安装十分慢，可以使用window系统的电脑讯雷等下载工具下载后，将安装包放至宿主机，再使用docker cp mysql-5.7.27-1.el7.x86_64.rpm-bundle.tar {容器ID}:/root/hadoop_CHD/mysql命令将安装包放至容器中，前提是容器的/root/hadoop_CHD/mysql目录必须事先创建。

2、可以将mysql部署在一个独立的容器中，若采用此方法则跳此步，单独部署的方法在此不再阐述。

4.5准备MySQL JDBC驱动

mkdir -p /root/hadoop_CHD/mysql-jdbc \
&& wget -O /root/hadoop_CHD/mysql-jdbc/mysql-connector-java-5.1.48.tar.gz \
https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.48.tar.gz \
&& ls /root/hadoop_CHD/mysql-jdbc

说明：

1、通过wget下载安装十分慢，可以使用window系统的电脑讯雷等下载工具下载后，将安装包放至宿主机，再使用docker cp mysql-connector-java-5.1.48.tar.gz {容器ID}:/root/hadoop_CHD/mysql-jdbc命令将安装包放至容器中，前提是容器的/root/hadoop_CHD/mysql-jdbc目录必须事先创建。

4.6准备Cloudera-Manager安装包

mkdir -p /root/hadoop_CHD/cloudera-repos \
&& wget -O /root/hadoop_CHD/cloudera-repos/allkeys.asc \
https://archive.cloudera.com/cm6/6.3.0/allkeys.asc \

&& wget -O /root/hadoop_CHD/cloudera-repos/enterprise-debuginfo-6.3.0-1281944.el7.x86_64.rpm \
https://archive.cloudera.com/cm6/6.3.0/redhat7/yum/RPMS/x86_64/enterprise-debuginfo-6.3.0-1281944.el7.x86_64.rpm \
&& wget -O /root/hadoop_CHD/cloudera-repos/oracle-j2sdk1.8-1.8.0+update181-1.x86_64.rpm \
https://archive.cloudera.com/cm6/6.3.0/redhat7/yum/RPMS/x86_64/oracle-j2sdk1.8-1.8.0+update181-1.x86_64.rpm \
&& ll /root/hadoop_CHD/cloudera-repos

说明：

1、通过wget下载mysql安装十分慢，可以使用window系统的电脑讯雷等下载工具下载后，将安装包放至宿主机，再使用docker cp 下载的rpm {容器ID}:/root/hadoop_CHD/cloudera-repos命令将安装包放至容器中，前提是容器的/root/hadoop_CHD/cloudera-repos目录必须事先创建。

4.7准备Parcel包

mkdir -p /root/hadoop_CHD/parcel \
&& wget -O /root/hadoop_CHD/parcel/ CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel \
https://archive.cloudera.com/cdh6/6.3.2/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel \
&& wget -O /root/hadoop_CHD/parcel/manifest.json \
https://archive.cloudera.com/cdh6/6.3.2/parcels/manifest.json \
&& ll /root/hadoop_CHD/parcel

说明：

1、通过wget下载mysql安装十分慢，可以使用window系统的电脑讯雷等下载工具下载后，将安装包放至宿主机，再使用docker cp 下载的parcel {容器ID}:/root/hadoop_CHD/parcel命令将安装包放至容器中，前提是容器的/root/hadoop_CHD/parcel目录必须事先创建。

2、随着时间推移官网可能会不定期删除测试不稳定的版本，可能导致上述链接无可用的下载资源，可以进入https://archive.cloudera.com/cdh6/找到想要的版本进行下载。

4.8 搭建本地yum源

yum -y install httpd createrepo \
&& systemctl start httpd \
&& systemctl enable httpd \
&& cd /root/hadoop_CHD/cloudera-repos/ && createrepo . \
&& mv /root/hadoop_CHD/cloudera-repos /var/www/html/ \
&& yum clean all \
&& ll /var/www/html/cloudera-repos

4.9安装jdk

cd /var/www/html/cloudera-repos/;rpm -ivh oracle-j2sdk1.8-1.8.0+update181-1.x86_64.rpm

4.10 安装配置MySQL数据库(采用docker独立安装跳过此步)

cd /root/hadoop_CHD/mysql/;tar -xvf mysql-5.7.27-1.el7.x86_64.rpm-bundle.tar \
&& yum install -y libaio numactl \
&& rpm -ivh mysql-community-common-5.7.27-1.el7.x86_64.rpm \

&& rpm -ivh mysql-community-libs-compat-5.7.27-1.el7.x86_64.rpm \
&& echo character-set-server=utf8 >> /etc/my.cnf \
&& rm -rf /root/hadoop_CHD/mysql/ \
&& yum clean all \
&& rpm -qa |grep mysql

4.11数据库授权

(
cat <<EOF
set password for root@localhost = password('123456Aa.');
grant all privileges on *.* to 'root'@'%' identified by '123456Aa.';
flush privileges;

SHOW DATABASES;
EOF
) >> /root/c.sql

获取MySQL初始密码

systemctl start mysqld && grep password /var/log/mysqld.log | sed 's/.*\(............\)$/\1/'

执行SQL脚本

mysql -uroot –p

输入查询出的默认密码，然后执行：

source /root/c.sql

4.12配置mysql jdbc驱动

mkdir -p /usr/share/java/ \
&& cd /root/hadoop_CHD/mysql-jdbc/;tar -zxvf mysql-connector-java-5.1.48.tar.gz \
&& cp  /root/hadoop_CHD/mysql-jdbc/mysql-connector-java-5.1.48/mysql-connector-java-5.1.48-bin.jar /usr/share/java/mysql-connector-java.jar \
&& rm -rf /root/hadoop_CHD/mysql-jdbc/ \
&& ls /usr/share/java/

4.13安装Cloudera Manager

(
cat <<EOF
[cloudera-manager]
name=Cloudera Manager 6.3.0
baseurl=http://172.10.0.2/cloudera-repos/
gpgcheck=0
enabled=1
EOF
) >> /etc/yum.repos.d/cloudera-manager.repo \
&& yum clean all \
&& yum makecache \
&& yum install -y cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server \
&& yum clean all \
&& rpm -qa | grep cloudera-manager

4.14配置parcel库

cd /opt/cloudera/parcel-repo/;mv /root/hadoop_CHD/parcel/* ./ \
&& sha1sum CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel | awk '{ print $1 }' > CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel.sha \
&& rm -rf /root/hadoop_CHD/parcel/ \
&& chown -R cloudera-scm:cloudera-scm /opt/cloudera/parcel-repo/* \

&& sleep 2 \
&& tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log | grep "INFO WebServerImpl:com.cloudera.server.cmf.WebServerImpl: Started Jetty server"

五、配置CDH的worker节点

以下为worker容器的准备方式，若为多个时，重复执行以下步骤，创建多个worker节点。

5.1创建多个worker容器

创建2个work容器，

Worker-1:

docker run -d \
--add-host cm.hadoop:172.10.0.2 \
--add-host cdh01.hadoop:172.10.0.3 \
--net hadoop_net \
--ip 172.10.0.3 \
-h cdh01.hadoop \
-p 20022:22 \
--restart always \
--name cdh01.hadoop \
--privileged \
centos7-cdh \
/usr/sbin/init \
&& docker ps

说明：

1、上述黄色部分，因创建不同的容器配置而不同，根据实际情况填写。

Worker-2:

docker run -d \
--add-host cm.hadoop:172.10.0.2 \
--add-host cdh02.hadoop:172.10.0.4 \
--net hadoop_net \
--ip 172.10.0.4 \
-h cdh02.hadoop \
-p 30022:22 \
--restart always \
--name cdh02.hadoop \
--privileged \
centos7-cdh \
/usr/sbin/init \
&& docker ps

5.2安装基本工具

上一步创建的所有容器均执行，修改root的登录密码改为root

docker exec –it {dockerId} /bin/bash
su root
passwd
root
root

然后执行：

yum install -y kde-l10n-Chinese telnet reinstall glibc-common vim wget ntp net-tools \
&& yum clean all

5.3配置中文环境变量

(
cat <<EOF
export LC_ALL=zh_CN.utf8
export LANG=zh_CN.utf8
export LANGUAGE=zh_CN.utf8
EOF
) >> ~/.bashrc \
&& localedef -c -f UTF-8 -i zh_CN zh_CN.utf8 \
&& source ~/.bashrc \
&& echo $LANG

5.4配置NTP时间同步服务

vim /etc/ntp.conf

更改为以下四个时钟服务器

server 0.cn.pool.ntp.org
server 1.cn.pool.ntp.org
server 2.cn.pool.ntp.org
server 3.cn.pool.ntp.org

启动ntp服务

systemctl start ntpd && \
systemctl enable ntpd && \
ntpdate -u 0.cn.pool.ntp.org && \
hwclock --systohc && \
date

5.5配置MySQL JDBC

mkdir -p /usr/share/java/ \
&& wget -O /usr/share/java/mysql-connector-java-5.1.48.tar.gz \
https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.48.tar.gz \
&& cd /usr/share/java/;tar -zxvf mysql-connector-java-5.1.48.tar.gz \
&& cp /usr/share/java/mysql-connector-java-5.1.48/mysql-connector-java-5.1.48-bin.jar /usr/share/java/mysql-connector-java.jar \
&& rm -rf mysql-connector-java-5.1.48 mysql-connector-java-5.1.48.tar.gz \
&& ls /usr/share/java/

说明：

1、通过wget下载安装十分慢，可以使用window系统的电脑讯雷等下载工具下载后，将安装包放至宿主机，再使用docker cp mysql-connector-java-5.1.48.tar.gz {容器ID}:/usr/share/java/命令将安装包放至容器中，前提是容器的/usr/share/java/目录必须事先创建。

5.6修改CM主机的host文件

echo "172.10.0.3      cdh01.hadoop cdh01" >> /etc/hosts
echo "172.10.0.4      cdh02.hadoop cdh02" >> /etc/hosts

注意：不是在worker节点上操作，而是在3.9创建的cloud-manager节点上操作，有多少个work容器，执行多少次，内容按真实情况填写即可。
