一、概述

  CDH，全称 Cloudera’s Distribution, including Apache Hadoop。是 Hadoop 众多分支中对应中的一种，由 Cloudera 维护，基于稳定版本的 Apache Hadoop 构建，提供了 Hadoop 的核心（可扩展存储、分布式计算），最为重要的是提供基于 web 的用户界面。

CDH 的优点：版本划分清晰，更新速度快，支持 Kerberos 安全认证，支持多种安装方式（如Yum、rpm 等）。

二、部署规划

  CDH 分为 Cloudera Manager 管理平台和 CDH parcel（parcel 包含各种组件的安装包）。

2.1 Cloudera Manager

Cloudera Manger地址：https://archive.cloudera.com/cm6/6.3.1/redhat7/yum/RPMS/x86_64/

ASC 文件：http://archive.cloudera.com/cm6/6.3.1/allkeys.asc

下载的文件保存在“cloudera-repos”目录下

2.2 CDH parcel

CDH parcel地址：https://archive.cloudera.com/cdh6/6.3.2/parcels/

    └── manifest.json

3 directories, 13 files

三、环境配置

3.1 配置映射

cat>>/etc/hosts <<EOF
192.168.137.129 db01
192.168.137.130 db02
192.168.137.131 db03
EOF

3.2 关闭防火墙&selinux

systemctl stop firewalld
systemctl disable firewalld
setenforce 0 && sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

3.3 配置互信

# 每个节点都执行
ssh-keygen -t rsa # 一路回车
# 将公钥添加到认证文件中
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
# 并设置authorized_keys的访问权限
chmod 600 ~/.ssh/authorized_keys

# 只要在一个节点执行即可
ssh db02 cat ~/.ssh/id_rsa.pub >>~/.ssh/authorized_keys
ssh db03 cat ~/.ssh/id_rsa.pub >>~/.ssh/authorized_keys

# 分发整合后的文件到其它节点
scp ~/.ssh/authorized_keys db02:~/.ssh/
scp ~/.ssh/authorized_keys db03:~/.ssh/

#各节点执行
ssh db01 date
ssh db02 date
ssh db03 date

3.4 创建用户

groupadd hadoop
useradd hadoop -g hadoop
id hadoop

3.5 安装jdk

[root@db01 cdh]# rpm -ivh oracle-j2sdk1.8-1.8.0+update181-1.x86_64.rpm
警告：oracle-j2sdk1.8-1.8.0+update181-1.x86_64.rpm: 头V3 RSA/SHA256 Signature, 密钥 ID b0b19c9f: NOKEY
准备中...                          ################################# [100%]
正在升级/安装...
   1:oracle-j2sdk1.8-1.8.0+update181-1################################# [100%]
cat>>/etc/profile <<EOF
export JAVA_HOME=/usr/java/jdk1.8.0_181-cloudera
export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
EOF
source /etc/profile

3.6 配置NTP

修改时区

ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

安装ntp

扫描二维码关注公众号，回复： 12681533 查看本文章 
yum install ntp -y
  • manager节点

修改/etc/ntp.conf

#server 0.centos.pool.ntp.org iburst
#server 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst
server ntp.aliyun.com
  • node节点
#server 0.centos.pool.ntp.org iburst
#server 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst
server master

启动ntp

systemctl enable ntpd.service
systemctl restart ntpd.service
ntpdc -c loopinfo #查看与时间同步服务器的时间偏差ntpq -p #查看当前同步的时间服务器
ntpstat #查看状态

3.7 安装MySQL驱动程序

需大于5.1.26 否则安装hive报错报错：org.apache.hadoop.hive.metastore.HiveMetaException: Failed to retrieve schema tables from Hive Metastore DB,Not supported

mv ~/mysql-connector-java-5.1.49/mysql-connector-java-5.1.49.jar /usr/share/java/mysql-connector-java.jar

四、安装MySQL

注意：需安装MySQL5.7版本，8.0暂不支持；不能开启GTID，因为要使用create table as select …语法；

4.1 创建MySQL用户组和用户

groupadd mysql
useradd -g mysql mysql -s /sbin/nologin
id mysql

4.2 解压软件&目录配置

tar xf mysql-5.7.32-el7-x86_64.tar
tar xf mysql-5.7.32-el7-x86_64.tar.gz -C /usr/local
tar xf mysql-test-5.7.32-el7-x86_64.tar.gz -C /usr/local
ln -s /usr/local/mysql-5.7.32-el7-x86_64/ /usr/local/mysql
mkdir -pv /data/mysql/{data,logs,tmp,binlog}
chown -R mysql.mysql /data/mysql/
chown -R mysql.mysql /usr/local/mysql/

4.3 配置环境变量

cat>>/etc/profile <<EOF
export PATH=$PATH:/usr/local/mysql//bin/
echo 'export PATH=$PATH:/usr/local/mysql//bin/' >> /etc/profile
EOF
source /etc/profile

4.4 修改配置文件

cat>>/etc/my.cnf <<EOF
