1 概述本文档描述CENTOS7.2操作系统部署CDH企业版的过程。Cloudera企业级数据中心的安装主要分为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；
2.外部数据库安装
3.安装Cloudera管理器；
4.安装CDH集群；
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。
这篇文档将着重介绍Cloudera管理器与CDH的安装，并基于以下假设：
CDH版本：CDH 5.10.0
5.采用ec2-user对集群进行部署
6.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/etc/hostname进行配置。
以cm节点（172.31.2.159）为例：
/etc/hostname文件如下：
| ip-172-31-2-159 |
|:----|
或者你可以通过命令修改立即生效
| ec2-user@ip-172-31-2-159 ~$ sudo hostnamectl set-hostname ip-172-31-2-159 |
|:----|
注意：这里修改hostname跟REDHAT6的区别
/etc/hosts文件如下:
| 172.31.2.159 ip-172-31-2-159172.31.12.108 ip-172-31-12-108172.31.5.236 ip-172-31-5-236172.31.7.96 ip-172-31-7-96 |
|:----|
以上两步操作，在集群中其它节点做相应配置。
在所有节点执行sudo setenforce 0 命令，此处使用批处理shell执行：
| ec2-user@ip-172-31-2-159 ~$ sh ssh_do_all.sh node.list "sudo setenforce 0" |
|:----|
集群所有节点修改/etc/selinux/config文件如下：
| SELINUX=disabledSELINUXTYPE=targeted |
|:----|
集群所有节点执行 sudo systemctl stop命令，此处通过shell批量执行命令如下：
在CentOS7.2的操作系统上，已经默认的安装了chrony，配置chrony时钟同步，将cm（172.31.2.159）服务作为本地chrony服务器，其它3台服务器与其保持同步，配置片段：
| ec2-user@ip-172-31-2-159 ~$ sh ssh_do_all.sh node.list "sudo systemctl restart chronyd" |
|:----|
| ec2-user@ip-172-31-2-159 ~$ sh ssh_do_all.sh node.list "chronyc sources" |
|:----|
| ec2-user@ip-172-31-2-159 ~$ sudo yum -y install httpd |
|:----|
| ec2-user@ip-172-31-2-159 ~$ sudo systemctl start httpdec2-user@ip-172-31-2-159 ~$ sudo systemctl stop httpd |
|:----|
MariaDB-10.2.1-centos7-x86\_64-client.rpm MariaDB-10.2.1-centos7-x86\_64-common.rpm MariaDB-10.2.1-centos7-x86\_64-compat.rpm MariaDB-10.2.1-centos7-x86\_64-server.rpm将包下载到本地，放在同一目录，执行createrepo命令生成rpm元数据。
此处使用apache2，将上述mariadb10.2.1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。
[ec2-user@ip-172-31-2-159 ~]$ sudo systemctl start mariadb
[ec2-user@ip-172-31-2-159 ~]$ sudo /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 fo
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 fa
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!
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。
配置Web服务器
此处使用apache2，将上述cdh5.10.0/cm5.10.0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。
| ec2-user@ip-172-31-2-159 ~$ sudo mv cdh5.10.0/ cm5.10.0/ /var/www/html/ |
|:----|
| ec2-user@ip-172-31-2-159 ~$ sudo yum -y install cloudera-manager-server |
|:----|
| ec2-user@ip-172-31-2-159 ~$ sudo systemctl start cloudera-scm-server |
|:----|
| ec2-user@ip-172-31-2-159 ~$ sudo netstat -lnpt | grep 7180tcp 0 0 0.0.0.0:7180 0.0.0.0:* LISTEN 6890/java |
