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'@'%';

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.reos.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
