1、准备工作

1.1 环境

centos7、jdk8、mysql5.7、python2.7

1.2文件下载

1.2.1 cloudmanger地址

https://archive.cloudera.com/cm6/6.0.0/redhat7/yum/RPMS/x86_64/ 

• cloudera-manager-agent-6.0.0-530873.el7.x86_64.rpm
• cloudera-manager-daemons-6.0.0-530873.el7.x86_64.rpm
  

• cloudera-manager-server-6.0.0-530873.el7.x86_64.rpm

  1.2.2 资源下载地址

  https://archive.cloudera.com/cdh6/6.0.0/parcels/

• CDH-6.0.0-1.cdh6.0.0.p0.537114-el7.parcel.sha256

• manifest.json

2、开始安装

2.1 服务器配置

2.1.1 修改HOST和主机名

1. vim /etc/hosts修改host，例如
   
   198.168.12.1 cdh1
   
   192.168.12.2 cdh2
   
   192.168.12.3 cdh3
   
   不能有大写字母和下划线

2. vim /etc/hostname修改主机名,修改完后三台机器分别执行hostname ***(当前节点的主机名)

   2.1.2 配置免密登录

3. ssh-keygen -t rsa -P ‘‘ -f ~/.ssh/id_rsa b、ssh-copy-id 每台服务器地址

   2.1.3 关闭防火墙

4. 临时关闭 systemctl stop firewalld

5. 禁止开机启动 systemctl disable firewalld

   2.1.4 安装jdk，配置环境变量

   这个大家都会，如果不会可以参考这个教程
   
   https://www.cnblogs.com/ocean-sky/p/8392444.html

   2.1.5 其他依赖

   每台服务器yum安装依赖包：redhat-lsb、portmap、httpd、mod_ssl、openssl-devel、python-psycopg2、MySQL-python、chkconfig、python、chkconfig、bind-utils、libxslt、zlib、sqlite、cyrus-sasl-plain、cyrus-sasl-gssapi、fuse、fuse-libs

   2.2 Mysql5.7安装(在主节点安装)

   2.2.1 安装

6. wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
7. yum -y install mysql57-community-release-el7-10.noarch.rpm
8. yum -y install mysql-community-server
9. 启动 systemctl start mysqld.service
10. 查看运行状态 systemctl status mysqld.service
11. 查看初始密码 grep "password" /var/log/mysqld.log
12. 登录后修改密码（尽量复杂一点，太简单了验证不通过，也可以查看如何关闭mysql校验规则） ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘new password‘;
13. 卸载yum源防止自动更新 yum -y remove mysql57-community-release-el7-10.noarch
    

14. 安装MySQL-shared-compat或MySQL-shared软件包(这是Cloudera Manager Agent软件包安装所必需的)yum install MySQL-shared-advanced

    2.2.2 创建CDH相关数据库

• create database scm default character set utf8 default collate utf8_general_ci;
• grant all on scm.* to ‘scm‘@‘%‘ identified by ‘password‘;
• create database amon default character set utf8 default collate utf8_general_ci;
• grant all on amon.* to ‘amon‘@‘%‘ identified by ‘password‘;
• create database rman default character set utf8 default collate utf8_general_ci;
• grant all on rman.* to ‘rman‘@‘%‘ identified by ‘password‘;
• create database hue default character set utf8 default collate utf8_general_ci;
• grant all on hue.* to ‘hue‘@‘%‘ identified by ‘password‘;
• create database metastore default character set utf8 default collate utf8_general_ci;
• grant all on metastore.* to ‘hive‘@‘%‘ identified by ‘password‘;
• create database sentry default character set utf8 default collate utf8_general_ci;
• grant all on sentry.* to ‘sentry‘@‘%‘ identified by ‘password‘;
• create database nav default character set utf8 default collate utf8_general_ci;
• grant all on nav.* to ‘nav‘@‘%‘ identified by ‘password‘;
• create database oozie default character set utf8 default collate utf8_general_ci;

• grant all on oozie.* to ‘oozie‘@‘%‘ identified by ‘password‘;

  2.3 CDH安装

1. mkdir /opt/cloudera-manager
2. 将cloudera-manager-agent-6.0.0-530873.el7.x86_64.rpm、cloudera-manager-daemons-6.0.0-530873.el7.x86_64.rpm 、cloudera-manager-server-6.0.0-530873.el7.x86_64.rpm
   复制到/opt/cloudera-manager文件夹中
3. 按 daemons、server、agent顺序解压
4. 修改文件/etc/cloudera-scm-agent/config.ini中serverhost指定server节点
5. 下载mysql-connector-java-5.1.47.jar包并复制为/usr/share/java/mysql-connector-java.jar
6. 在主节点执行
   /opt/cloudera/cm/schema/scmpreparedatabase.sh mysql -h 主节点ip --scm-host 主节点ip scm scm
7. mkdir -p /opt/cloudera/parcel-repo
8. 将CDH-6.0.0-1.cdh6.0.0.p0.537114-el7.parcel、CDH-6.0.0-1.cdh6.0.0.p0.537114-el7.parcel.sha256、manifest.json复制到/opt/cloudera/parcel-repo
9. 将CDH-6.0.0-1.cdh6.0.0.p0.537114-el7.parcel.sha256 重命名为 CDH-6.0.0-1.cdh6.0.0.p0.537114-el7.parcel.sha

10. 在manifest.json文件中，找到对应版本的秘钥，复制到CDH-6.0.0-1.cdh6.0.0.p0.537114-el7.parcel.sha文件中。
    11.启动systemctl start cloudera-scm-agent、systemctl start cloudera-scm-server

    2.4 集群配置

    2.4.1 禁用透明大页面压缩

    echo never > /sys/kernel/mm/transparent_hugepage/defrag
    
    echo never > /sys/kernel/mm/transparent_hugepage/enabled

    2.4.1 分配组件

    访问http://192.168.1.1:7180开始配置集群组件
    因为是先安装集群后编写文档，没有截图就没有详细些。
