CDH及其他资源下载

百度网盘 请输入提取码pan.baidu.com

提取码 : u07l

一、前置任务

创建docker自定义网络

docker network create --subnet=172.10.0.0/16 CDH

下载上述资源

在下载后CDH文件夹中，Dockerfile同级目录执行以下命令来创建基础系统镜像

docker build -t centos7-cdh .

二、构建主节点

2.1 初始化环境

启动容器

docker run -d `
--add-host cm.hadoop:172.10.0.2 `
--net CDH `
--ip 172.10.0.2 `
-h cm.hadoop `
-p 10022:22 `
-p 7180:7180 `
--name cm.hadoop `
--privileged=true `
-v /sys/fs/cgroup:/sys/fs/cgroup:ro --tmpfs /run --tmpfs /run/lock `
--stop-signal=RTMIN+3 `
centos7-cdh `
/usr/sbin/init

拷贝hadoop_CDH资源文件夹到主节点

docker cp hadoop_CDH cm.hadoop:/root/hadoop_CDH

进入主节点

docker exec -it cm.hadoop /bin/bash

设置root密码

passwd
1009
1009

安装常用证书，然后换清华源,升级并安装基础软件包

centos | 镜像站使用帮助 | 清华大学开源软件镜像站 | Tsinghua Open Source Mirrormirrors.tuna.tsinghua.edu.cn

清华镜像

yum install -y ca-certificates 
#换源
yum update -y && yum upgrade -y
yum install -y kde-l10n-Chinese telnet reinstall glibc-common vim wget ntp net-tools ca-certificates sshpass pssh
yum clean all

2.2 配置中文环境

(
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

2.3 设置时间同步

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

调整时区

cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

启动ntp服务

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

2.4 搭建本地yum源

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

2.5安装jdk

cd /var/www/html/cloudera-repos/

rpm -ivh oracle-j2sdk1.8-1.8.0update181-1.x86_64.rpm

2.6安装配置MySQL数据库

cd /root/hadoop_CDH/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-5.7.27-1.el7.x86_64.rpm \
&& rpm -ivh mysql-community-client-5.7.27-1.el7.x86_64.rpm \
&& rpm -ivh mysql-community-server-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_CDH/mysql/ \
&& yum clean all \
&& rpm -qa |grep mysql

2.7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;
CREATE DATABASE scm DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
CREATE DATABASE amon DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
CREATE DATABASE rman DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
CREATE DATABASE hue DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
CREATE DATABASE metastore DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
CREATE DATABASE sentry DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
CREATE DATABASE nav DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
CREATE DATABASE navms DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
CREATE DATABASE oozie DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
GRANT ALL ON scm.* TO 'scm'@'%' IDENTIFIED BY '123456Aa.';
GRANT ALL ON amon.* TO 'amon'@'%' IDENTIFIED BY '123456Aa.';
GRANT ALL ON rman.* TO 'rman'@'%' IDENTIFIED BY '123456Aa.';
GRANT ALL ON hue.* TO 'hue'@'%' IDENTIFIED BY '123456Aa.';
GRANT ALL ON metastore.* TO 'hive'@'%' IDENTIFIED BY '123456Aa.';
GRANT ALL ON sentry.* TO 'sentry'@'%' IDENTIFIED BY '123456Aa.';
GRANT ALL ON nav.* TO 'nav'@'%' IDENTIFIED BY '123456Aa.';
GRANT ALL ON navms.* TO 'navms'@'%' IDENTIFIED BY '123456Aa.';
GRANT ALL ON oozie.* TO 'oozie'@'%' IDENTIFIED BY '123456Aa.';
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/'

使用密码登录进入mysql

mysql -u root –p

登陆后执行

source /root/c.sql

2.8配置mysql jdbc驱动

mkdir -p /usr/share/java/ \
&& cd /root/hadoop_CDH/mysql-jdbc/;tar -zxvf mysql-connector-java-5.1.48.tar.gz \
&& cp  /root/hadoop_CDH/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_CDH/mysql-jdbc/ \
&& ls /usr/share/java/

2.9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

2.10配置parcel库

cd /opt/cloudera/parcel-repo/;mv /root/hadoop_CDH/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_CDH/parcel/ \
&& chown -R cloudera-scm:cloudera-scm /opt/cloudera/parcel-repo/* \
&& ll /opt/cloudera/parcel-repo/

2.11初始化scm库

/opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm scm 123456Aa.

2.12启动cloudera-server服务

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

三、配置从节点

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。

3.1创建多个worker容器

docker run -d `
--add-host cm.hadoop:172.10.0.2 `
--add-host cdh01.hadoop:172.10.0.3 `
--net CDH `
--ip 172.10.0.3 `
-h cdh01.hadoop `
-p 20022:22 `
--name cdh01.hadoop `
--privileged=true `
-v /sys/fs/cgroup:/sys/fs/cgroup:ro --tmpfs /run --tmpfs /run/lock `
--stop-signal=RTMIN+3 `
centos7-cdh `
/usr/sbin/init 

以此类推

docker run -d `
--add-host cm.hadoop:172.10.0.2 `
--add-host cdh02.hadoop:172.10.0.4 `
--net CDH `
--ip 172.10.0.4 `
-h cdh02.hadoop `
-p 30022:22 `
--name cdh02.hadoop `
--privileged=true `
-v /sys/fs/cgroup:/sys/fs/cgroup:ro --tmpfs /run --tmpfs /run/lock `
--stop-signal=RTMIN+3 `
centos7-cdh `
/usr/sbin/init

3.2配置免密

进入所有从节点，配置root密码和主节点一样。

进入主节点，/etc/hosts添加如下

172.10.0.2      cm.hadoop cm
172.10.0.3      cdh01.hadoop cdh01
172.10.0.4      cdh02.hadoop cdh02
172.10.0.5      cdh03.hadoop cdh03

按照下面指示创建脚本文件

脚本

修改config.sh后把/etc/hosts和/root/Shell发送给所有节点一份

bash scp_to_all.sh /etc/hosts /etc/
bash scp_to_all.sh /root/Shell /root

配置主节点到所有节点的免密

bash ssh_one_to_all.sh

创建host.txt文件，写入从节点名称

cdh01.hadoop
cdh02.hadoop
cdh03.hadoop

3.3装基本工具

给所有从节点安装常用证书

pssh -h host.txt yum install -y ca-certificates

创建tmp.sh，写入以下内容

sed -e 's|^mirrorlist=|#mirrorlist=|g' \
         -e 's|^#baseurl=http://mirror.centos.org/centos|baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos|g' \
         -i.bak \
         /etc/yum.repos.d/CentOS-*.repo

让从节点都执行这个本地(主节点)脚本，来更新清华源

pssh -h host.txt -I < tmp.sh 
pssh -h host.txt -t 360 yum makecache -y
pssh -h host.txt -t 360 yum update -y
pssh -h host.txt -t 360 yum upgrade -y

安装基础软件包

pssh -h host.txt -t 360 yum -y install kde-l10n-Chinese telnet reinstall glibc-common vim wget ntp net-tools
pssh -h host.txt -t 360 yum -y clean all

3.4配置中文环境变量

将以下内容写入tmp.sh

(
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

pssh -h host.txt -I < tmp.sh

3.5配置NTP时间同步服务

更改四个时钟服务器

bash scp_to_all.sh /etc/ntp.conf /etc

调整时区

pssh -h host.txt cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

启动ntp服务，将以下写入sh

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

pssh -h host.txt -I < tmp.sh

这里出现Failure并不代表从节点调整时间失败，可以手动检查一下

3.6配置MySQL JDBC

写入sh后pssh

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/
