三、环境初始化

1、设置Linux主机名

各自节点执行修改主机名命令：

hostnamectl set-hostname node06.research.com

hostnamectl set-hostname node07.research.com

hostnamectl set-hostname node10.research.com

每个节点上都添加一下内容至 /etc/hosts：

10.295.102.6 node06.research.com
10.295.102.7 node07.research.com
10.295.102.10 node10.research.com

2、关闭集群防火墙

每个节点上执行

systemctl stop firewalld && systemctl disable firewalld && iptables -F

3、关闭集群selinux

vi /etc/selinux/config

SELINUX=disabled

修改成disabled之后重启linux系统生效

4、设置集群时钟同步

所有节点设置亚洲上海海时区

[root@node06 ~]# timedatectl set-timezone Asia/Shanghai

[root@node07 ~]# timedatectl set-timezone Asia/Shanghai

[root@node10 ~]# timedatectl set-timezone Asia/Shanghai

#所有节点安装ntp

[root@node06 ~]# yum install -y ntp

#选取node06为ntp的主节点

[root@node06 ~]# vi /etc/ntp.conf

#time

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

#当外部时间不不可⽤用时，可使⽤用本地硬件时间

server 127.127.1.0 iburst local clock

#允许哪些⽹网段的机器器来同步时间

restrict 172.21.230.0 mask 255.255.255.0 nomodify notrap

#开启ntpd及查看状态

[root@node06 ~]# systemctl start ntpd

[root@node06 ~]# systemctl status ntpd

5、每个节点部署JDK

[root@node06 ~]# mkdir /usr/java
[root@node06 ~]# tar -zxf cdh/jdk-8u191-linux-x64.tar.gz -C /usr/java/
[root@node06 ~]# chown -R root:root /usr/java/jdk1.8.0_191
[root@node06 ~]# echo "export JAVA_HOME=/usr/java/jdk1.8.0_191" >> /etc/profile
[root@node06 ~]# echo "export PATH=/usr/java/jdk1.8.0_191/bin:${PATH}" >> /etc/profile
[root@node06 ~]# source /etc/profile
[root@node06 ~]# which java
/usr/java/jdk1.8.0_191/bin/java

[root@node06 ~]# java -version
java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)

6、主节点部署MySQL

参考：https://github.com/Hackeruncle/MySQL/blob/master/MySQL%205.7.11%20Install.txt

7、创建CDH源数据库、用户、amon服务的数据库

create database cmf DEFAULT CHARACTER SET utf8;
create database amon DEFAULT CHARACTER SET utf8;
grant all on cmf.* TO 'cmf'@'%' IDENTIFIED BY 'www.research.com';
grant all on amon.* TO 'amon'@'%' IDENTIFIED BY 'www.research.com';
flush privileges;

8、主节点部署JDBC

[root@node06 ~]# mkdir -p /usr/share/java
[root@node06 ~]# cp cdh/mysql-connector-java-5.1.47.jar /usr/share/java/
[root@node06 ~]# cd /usr/share/java/
[root@node06 java]# mv mysql-connector-java-5.1.47.jar mysql-connector-java.jar
[root@node06 java]#

四、CDH部署

1、离线部署CM server及agent

1.1【所有节点】创建软件目录解压软件

[root@node06 opt]# mkdir cloudera-manager
[root@node06 opt]# cd
[root@node06 ~]# cd cdh
[root@node06 cdh]# tar -zxf cm6.3.1-redhat7.tar.gz -C/opt/cloudera-manager

1.2【06主节点执行】选择06为主节点作为cm server，直接部署

[root@node06 cdh]# cd /opt/cloudera-manager/cm6.3.1/RPMS/x86_64/
[root@node06 x86_64]# rpm -ivh cloudera-manager-daemons-6.3.1-1466458.el7.x86_64.rpm --nodeps --force
[root@node06 x86_64]# rpm -ivh cloudera-manager-server-6.3.1-1466458.el7.x86_64.rpm --nodeps --force

1.3【所有节点(包含主节点)】选择所有节点作为cm agent，直接部署

cd /opt/cloudera-manager/cm6.3.1/RPMS/x86_64
rpm -ivh cloudera-manager-daemons-6.3.1-1466458.el7.x86_64.rpm --nodeps --force
rpm -ivh cloudera-manager-agent-6.3.1-1466458.el7.x86_64.rpm --nodeps --force

1.4【所有节点】修改agent配置，指向server节点06

sed -i "s/server_host=localhost/server_host=node06.research.com/g" /etc/cloudera-scm-agent/config.ini

1.5【修改主节点】的server配置

[root@node06 x86_64]# vim /etc/cloudera-scm-server/db.properties

com.cloudera.cmf.db.type=mysql

com.cloudera.cmf.db.host=node06.research.com

com.cloudera.cmf.db.name=cmf

com.cloudera.cmf.db.user=cmf

com.cloudera.cmf.db.password=www.research.com

com.cloudera.cmf.db.setupType=EXTERNAL

2、主节点部署离线parcel源

2.1 安装httpd

yum install -y httpd

2.2 部署离线parcel源

[root@node06 ~]# mkdir -p /var/www/html/cdh6_parcel
[root@node06 ~]# cp cdh/CDH-6.3.1-1.cdh6.3.1.p0.1470567-el7.parcel /var/www/html/cdh6_parcel/
[root@node06 ~]# mv cdh/CDH-6.3.1-1.cdh6.3.1.p0.1470567-el7.parcel.sha1 /var/www/html/cdh6_parcel/CDH-6.3.1[root@node[root@node06 ~]# mv cdh/CDH-6.3.1-1.cdh6.3.1.p0.1470567-el7.parcel.sha1 /var/www/html/cdh6_parcel/CDH-6.3.1-1.cdh6.3.1.p0.1470567-el7.parcel.sha
[root@node06 ~]# mv cdh/manifest.json /var/www/html/cdh6_parcel/
[root@node06 ~]# systemctl start httpd

2.3 页面访问http://10.295.102.6/cdh6_parcel/

3、06主节点启动server

[root@node06 ~]# systemctl start cloudera-scm-server
[root@node06 ~]# ll /var/log/cloudera-scm-server/
total 20
-rw-r----- 1 cloudera-scm cloudera-scm 16679 Dec 10 18:27 cloudera-scm-server.log
