Cloudera在2018年11月29日发布了CDH5.16.1，新功能介绍可以参考Fayson之前的文章《0466-CDH5.16.1和CM5.16.1的新功能》。本文档主要描述如何在Redhat7.4安装CDH5.16.1。Cloudera大数据平台的安装主要分为4个步骤：
1.集群服务器配置，包括安装操作系统、关闭防火墙、同步服务器时钟等，又称为集群安装的前置准备，关于更多前置条件准备也可以参考Fayson之前的的文档《CDH安装前置准备》；
2.安装Cloudera Manager；
3.通过Cloudera Manager的Web UI向导式安装CDH集群；
4.集群完整性检查，包括HDFS文件系统、MapReduce、Hive等是否可以正常运行。
本文操作说明基于以下假设：
1.操作系统版本：Redhat7.4
2.CDH和CM版本均为5.16.1
3.采用root对集群进行部署
4.您已经下载CDH和CM的安装包
集群中各个节点之间能互相通信使用静态IP地址。IP地址和主机名通过/etc/hosts配置，主机名通过/etc/hostname进行配置。
以cm节点（172.31.13.38）为例：
/etc/hostname文件如下：
ip-172-31-13-38.ap-southeast-1.compute.internal或者你可以通过命令修改立即生效
[root@ip-172-31-13-38 ~]$ hostnamectl set-hostname ip-172-31-13-38.ap-southeast-1.compute.internal<font face="微软雅黑" size=4 color=red >注意：这里修改hostname跟REDHAT6的区别
/etc/hosts文件如下:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.31.13.38 ip-172-31-13-38.ap-southeast-1.compute.internal
172.31.11.232 ip-172-31-11-232.ap-southeast-1.compute.internal
172.31.11.9 ip-172-31-11-9.ap-southeast-1.compute.internal
172.31.13.166 ip-172-31-13-166.ap-southeast-1.compute.internal以上两步操作，在集群中其它节点做相应配置。确认需要安装的4台主机的hosts文件：
在所有节点执行setenforce 0 命令，此处使用批处理shell执行：
[root@ip-172-31-13-38 ~]$ sh ssh_do_all.sh node.list "setenforce 0"
集群所有节点修改/etc/selinux/config文件如下：
SELINUX=disabled
SELINUXTYPE=targeted检查所有机器是否已修改成功：
sh ssh_do_all.sh node.list "cat /etc/selinux/config | grep SELINUX"
集群所有节点执行systemctl stop firewalld命令，此处通过shell批量执行命令如下：
[root@ip-172-31-13-38 ~]$ sh ssh_do_all.sh node.list "systemctl stop firewalld"
[root@ip-172-31-13-38 ~]$ sh ssh_do_all.sh node.list "systemctl disable firewalld"
[root@ip-172-31-13-38 ~]$ sh ssh_do_all.sh node.list "systemctl status firewalld"
在Redhat7.x的操作系统上，已经默认的安装了chrony，我们这里先卸载chrony，然后安装ntp。使用ntp来配置各台机器的时钟同步，将cm（172.31.13.38）服务作为本地ntp服务器，其它3台服务器与其保持同步。
1.所有机器卸载chrony
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "yum -y remove chrony"
2.所有机器安装ntp
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "yum -y install ntp"
3.cm机器配置时钟与自己同步
[root@ip-172-31-16-68 shell]# vim /etc/ntp.conf
#server 0.rhel.pool.ntp.org iburst
#server 1.rhel.pool.ntp.org iburst
#server 2.rhel.pool.ntp.org iburst
#server 3.rhel.pool.ntp.org iburst
server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 10
4.集群其它节点，配置找cm机器去同步
#server 0.rhel.pool.ntp.org iburst
#server 1.rhel.pool.ntp.org iburst
#server 2.rhel.pool.ntp.org iburst
#server 3.rhel.pool.ntp.org iburst
server 172.31.13.38
5.重启所有机器的ntp服务
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "systemctl restart ntpd"
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "systemctl status ntpd"
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "systemctl enable ntpd"
6.验证始终同步，在所有节点执行ntpq -p命令，如下使用脚本批量执行
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "ntpq -p"
左边出现*号表示同步成功。
所有节点执行
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "echo vm.swappiness = 10 >> /etc/sysctl.conf"
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "sysctl vm.swappiness=10"
所有节点执行：
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "echo never > /sys/kernel/mm/transparent_hugepage/defrag "
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "echo never > /sys/kernel/mm/transparent_hugepage/enabled"
设置开机自关闭
将如下脚本添加到/etc/rc.d/rc.local文件中
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同步到所有节点

[root@ip-172-31-2-159 ~]$ sudo yum repolist1.安装MariaDB
[root@ip-172-31-13-38 ~]# yum -y install mariadb
[root@ip-172-31-13-38 ~]# yum -y install mariadb-server
2.启动并配置MariaDB
[root@ip-172-31-13-38 ~]# systemctl start mariadb
[root@ip-172-31-13-38 ~]# systemctl enable mariadb
[root@ip-172-31-13-38 ~]# /usr/bin/mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we‘ll need the current
password for the root user. If you‘ve just installed MariaDB, and
you haven‘t set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] Y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] Y
... Success!
Normally, root should only be allowed to connect from ‘localhost‘. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] n
... skipping.
By default, MariaDB comes with a database named ‘test‘ that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] Y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] Y
... Success!
Cleaning up...
All done! If you‘ve completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
3.建立CM，Hive等需要的表

Enter password:

1.下载CM5.16.1的安装包，地址为：
http://archive.cloudera.com/cm5/redhat/7/x86_64/cm/5.16.1/RPMS/x86_64/cloudera-manager-agent-5.16.1-1.cm5161.p0.1.el7.x86_64.rpm

2.下载CDH5.16.1的安装包，地址为：
http://archive.cloudera.com/cdh5/parcels/5.16.1/CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel

http://archive.cloudera.com/cdh5/parcels/5.16.1/manifest.json
3.将Cloudera Manager安装需要的7个rpm包下载到本地，放在同一目录，执行createrepo命令生成rpm元数据。
[root@ip-172-31-13-38 cm5.16.1]# ll

4.配置Web服务器
将上述cdh5.16.1/cm5.16.1目录移动到/var/www/html目录下, 使得用户可以通过HTTP访问这些rpm包。
[root@ip-172-31-13-38 ~]# mv cm5.16.1/ cdh5.16.1/ /var/www/html/
验证浏览器能否正常访问
5.制作Cloudera Manager的repo源
[root@ip-172-31-13-38 ~]# vim /etc/yum.repos.d/cm.repo
[cmrepo]
name = cm_repo
baseurl = http://172.31.13.38/cm5.16.1
enable = true
gpgcheck = false
[root@ip-172-31-13-38 yum.repos.d]# yum repolist
Loaded plugins: amazon-id, rhui-lb, search-disabled-repos
repo id repo name status
cmrepo cm_repo 7

rhui-REGION-rhel-server-rh-common/7Server/x86_64 Red Hat Enterprise Linux Server 7 RH Commo 233
repolist: 20,909
6.验证安装JDK
yum -y install oracle-j2sdk1.7-1.7.0+update67-1
1.通过yum安装Cloudera Manager Server
yum -y install cloudera-manager-server
2.初始化数据库
[root@ip-172-31-13-38 yum.repos.d]# /usr/share/cmf/schema/scm_prepare_database.sh mysql cm cm password
JAVA_HOME=/usr/java/jdk1.7.0_67-cloudera
Verifying that we can write to /etc/cloudera-scm-server

[ main] DbCommandExecutor INFO Successfully connected to database.
All done, your SCM database is configured correctly!
3.启动Cloudera Manager Server
[root@ip-172-31-13-38 ~]# systemctl start cloudera-scm-server
4.检查端口是否监听
[root@ip-172-31-13-38 ~]# netstat -lnpt | grep 7180
tcp 0 0 0.0.0.0:7180 0.0.0.0:* LISTEN 3331/java
5.通过http://13.250.14.115:7180/cmf/login访问CM
1.admin/admin登录到CM
2.同意license协议，点击继续
3.选择60试用，点击继续
4.点击“继续”
5.输入主机ip或者名称，点击搜索找到主机后点击继续
6.点击“继续”
注意这里列出来的CDH版本都是系统最开始默认的，来自于Cloudera公网的下载源仓库，这里我们需要先将CDH的安装源修改一下。
7.使用parcel选择，点击“更多选项”,点击“-”删除其它所有地址，输入
http://172.31.13.38/cdh5.16.1，点击“保存更改”
保存更改后，这时回到上个页面会看到我们之前准备好的http的CDH5.16.1的源，如果显示不出来，可能http源配置有问题，请参考前面步骤仔细进行检查。
8.选择自定义存储库，输入cm的http地址
9.点击“继续”，进入下一步安装jdk
10.点击“继续”，进入下一步，默认多用户模式，不需要进行任何勾选
11.点击“继续”，进入下一步配置ssh账号密码
12.点击“继续”，进入下一步，安装Cloudera Manager相关到各个节点
13.点击“继续”，进入下一步安装cdh到各个节点
14.点击“继续”，进入下一步主机检查，确保所有检查项均通过
点击完成进入服务安装向导。
1.选择需要安装的服务
2.点击“继续”，进入集群角色分配
3.点击“继续”，进入下一步，测试数据库连接
4.测试成功，点击“继续”，进入目录设置，此处使用默认默认目录，根据实际情况进行目录修改
5.点击“继续”，进入各个服务启动
6.安装成功
7.安装成功后进入CM管理界面主页
CDH从5.13开始，直接打包Kudu，不再需要下载额外的Parcel和csd文件。CDH5.13集成的是Kudu1.5，CDH5.16.1集成的是Kudu1.7。
1.通过CM安装Kudu1.7
添加Kudu服务
2.选择Master和Tablet Server
3.配置相应的目录，注：无论是Master还是Tablet根据实际情况数据目录(fs_data_dir)应该都可能有多个，以提高并发读写，从而提高Kudu性能。
4.启动Kudu服务
5.安装完毕
6.配置Impala
回到主页重启Impala和Hue
至此，CDH5.16.1+Kudu1.7安装完毕。
因为微信单篇文章字数限制，Fayson这里省略了快速组件验证章节。你可以参考Fayson以前的文章。
