一： 关于CDP DC 7.0.3 概述

1.1 CDP dc 7.0.3

CDP DC7.0.3是Cloudera与Hortonworks合并后，第一个融合CDH和HDP所有组件的on-premise版本，CDP Data Center主要由Cloudera Runtime构成，Cloudera Runtime由超过35个开源项目组成，当然CDP Data Center还包括其它功能如管理功能Cloudera Manager，Key Management，专业支持等，如下图所示：

1.2 Cloudera Runtime的主要组件版本如下图所示：

二： 系统环境初始化

2.1 系统环境介绍

OS: rhel7.7x64 
cat /etc/hosts 
---
192.168.100.21  rhel01.flyfish
192.168.100.22  rhel02.flyfish
192.168.100.23  rhel03.flyfish
192.168.100.24  rhel04.flyfish
192.168.100.25  rhel05.flyfish
192.168.100.26  rhel06.flyfish
---
本次采用 前四台 机器

2.2 无密钥登录配置

做root用户无密钥认证
 ssh-keygen ---一直敲回车到最后
 cat id_rsa.pub >> authorized_keys 
 将所有的公钥导入authorized_keys  分发到 所有的 机器的.ssh/ 下面
 然后测试

2.3关闭 firewalld，iptables 与 selinux

所有节点都要配置：
yum install -y firewall* iptable* 
  (1) 关闭firewalld
 systemctl stop firewalld.service
 systemctl disable firewalld.service
 firewall-cmd --state
 (2) 关闭iptables 
 iptables -F
 systemctl stop iptables.service 
 service iptables save
 systemctl disable iptables.service 
 (3) 禁用 selinux 
  sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config  
  setenforce 0
  getenforce 0
  sestatus
  重启机器
  reboot

2.4 所有机器更改RHEL7.7X64的文件句柄数

vim /etc/security/limits.conf
---
*               soft    nofile          65535
*               hard    nofile          1029345
*               soft    nproc           unlimited
*               hard    nproc           unlimited
*               soft    memlock         unlimited
*               hard    memlock         unlimited
---

ansible cdh7 -m copy -a "src=/etc/security/limits.conf dest=/etc/security/" 

2.5 时间同步：

所有机器 yum install chrony*
1. rhel01.flyfish:
vim /etc/chrony.conf 增加
----
注释掉相关默认的server
server ntp1.aliyun.com iburst
allow 192.168.100.0/24
service chronyd start
chkconfig chronyd on 
2. rhel02.flyfish----rhel04.flyfish 同步rhel01.flyfish
vim /etc/chrony.conf
----
注释掉默认的server
server 192.168.100.21 iburst
----
service chronyd stop 
service chronyd start 
chkconfig chronyd on

2.8 设置swap

将所有的swap为1，并即时生效
ansible cdh7 -m shell -a "echo '1' > /proc/sys/vm/swappiness"
ansible cdh7 -m shell -a "sysctl -a | grep vm.swappiness"

vim /etc/sysctl.conf 
----
最后加上：
vm.swappiness = 1 
----
sysctl -p

2.8 设置最大透明数

ansible cdh7 -m shell -a "echo 'never' > /sys/kernel/mm/transparent_hugepage/defrag"
ansible cdh7 -m shell -a "echo 'never' > /sys/kernel/mm/transparent_hugepage/enabled"
ansible cdh7 -m shell -a "cat /sys/kernel/mm/transparent_hugepage/enabled"
ansible cdh7 -m shell -a "cat /sys/kernel/mm/transparent_hugepage/defrag"

修改所有节点的/etc/rc.d/rc.local文件的权限以实现开机执行
ansible cdh7 -m shell -a "chmod +x /etc/rc.d/rc.local"
vim /etc/rc.d/rc.local
---
最后加上：
if test -f /sys/kernel/mm/transparent_hugepage/enabled; 
then
echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; 
then
echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi
---
ansible cdh7 -m copy -a "src=/etc/rc.d/rc.local dest=/etc/rc.d/"
ansible cdh7 -m shell -a "tail -f /etc/rc.d/rc.local"

2.9 配置httpd 服务器

ansible rhel01.flyfish -m yum -a "state=present name=httpd"
ansible rhel01.flyfish -m service -a "name=httpd state=started"
ansible rhel01.flyfish -m shell -a "ps -ef |grep httpd"

修改 /etc/httpd/conf/httpd.conf 在<IfModule mime_module>中修改以下内容
vim /etc/httpd/conf/httpd.conf
---
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz .parcel
---
service httpd restart 

2.10 安装maridb 数据库

yum install mariadb* 
service mariadb start 
chkonfig mariadb on 
mysql_secure_installation

2.11 创建CM，Hive等需要的表

vim cm.sql
----
create database metastore default character set utf8;
CREATE USER 'hive'@'%' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON metastore. * TO 'hive'@'%';
FLUSH PRIVILEGES;
create database cm default character set utf8;
CREATE USER 'cm'@'%' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON cm. * TO 'cm'@'%';
FLUSH PRIVILEGES;
create database rm default character set utf8;
CREATE USER 'rm'@'%' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON rm. * TO 'rm'@'%';
FLUSH PRIVILEGES;
create database hue default character set utf8;
CREATE USER 'hue'@'%' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON hue. * TO 'hue'@'%';
FLUSH PRIVILEGES;
create database oozie default character set utf8;
CREATE USER 'oozie'@'%' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON oozie. * TO 'oozie'@'%';
FLUSH PRIVILEGES;
create database ranger default character set utf8;
CREATE USER 'rangeradmin'@'%' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON ranger. * TO 'rangeradmin'@'%';
FLUSH PRIVILEGES;
----
mysql -uroot -pflyfish225
source cm.sql

2.12 安装JDBC驱动

mkdir -p /usr/share/java/
tar -zxvf mysql-connector-java-5.1.44.tar.gz
mv mysql-connector-java-5.1.44-bin.jar /usr/share/java
cd /usr/share/java/
mv mysql-connector-java-5.1.44-bin.jar mysql-connector-java.jar 
chmod 777 mysql-connector-java.jar

三： 构建CDP DC 7.0.3

3.1 安装 jdk

所有节点 卸载系统自带jdk
rpm -qa |grep jdk 
rpm -e java-1.8.0-openjdk-1.8.0.222.b03-1.el7.x86_64 copy-jdk-configs-3.3-10.el7_5.noarch java-1.8.0-openjdk-headless-1.8.0.222.b03-1.el7.x86_64 --nodeps 
yum -y install openjdk8-8.0+232_9-cloudera
vim /etc/profile
---
到最后加上jdk 的环境变量
export JAVA_HOME=/usr/java/jdk1.8.0_232-cloudera
export CLASSPATH=.:$JAVA_HOME/jre/lib:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
----
source /etc/profile
java -version 

3.2 配置cdh7.0.3 的源

mv cdh7.0.3 cdh7
cd cdh7 
createrepo .
cd ..
mv cdh7 /var/www/html/

制作Cloudera Manager的repo源
cd /etc/yum.repos.d/
vim cdh.repo
---
[cmrepo]
name = cm_repo
baseurl = http://192.168.100.21/cdh7/
enable = true
gpgcheck = false
---
ansible cdh7 -m copy -a "src=/etc/repos.d/cdh7.repo dest=/etc/repos.d/"
yum repolist

3.3 安装Cloudera Manager Server

yum -y install cloudera-manager-server

初始化数据库
/opt/cloudera/cm/schema/scm_prepare_database.sh mysql cm cm password

启动Cloudera Manager Server
systemctl start cloudera-scm-server
systemctl status cloudera-scm-server
cd /var/log/cloudera-scm-server
tail -100f cloudera-scm-server.log
netstat -nultp |grep 7180

3.4 通过http://192.168.100.21:7180/cmf/login访问CM

用户名：admin
密码： admin

登录到CM，选择60天试用，点击继续

集群安装：

集群名字

识别集群的主机

Parcel Repository & Network Settings

安装 cloudera-scm-agent

分配parcel包

点击Inspect Network Performance和Inspect Hosts，检查主机

定义服务：

点击“继续”，进入下一步，测试数据库连接

首先输入CM的用户名和密码admin/admin
以下4个密码，都需要包含至少一个字母与一个数字，为了安装方便都输入admin@123

安装服务初始化
