1.文章編寫目的

Cloudera在2018年11月29日發布了CDH5.16.1，新功能介紹可以參考Fayson之前的文章《0466-CDH5.16.1和CM5.16.1的新功能》。本文檔主要描述如何在Redhat7.4安裝CDH5.16.1。Cloudera大數據平臺的安裝主要分為4個步驟：

1.集群服務器配置，包括安裝操作系統、關閉防火墻、同步服務器時鐘等，又稱為集群安裝的前置準備，關於更多前置條件準備也可以參考Fayson之前的的文檔《CDH安裝前置準備》；

2.安裝Cloudera Manager；

3.通過Cloudera Manager的Web UI向導式安裝CDH集群；

4.集群完整性檢查，包括HDFS文件系統、MapReduce、Hive等是否可以正常運行。

本文操作說明基於以下假設：

1.操作系統版本：Redhat7.4

2.CDH和CM版本均為5.16.1

3.采用root對集群進行部署

4.您已經下載CDH和CM的安裝包

2.前置準備

2.1.hostname及hosts配置

集群中各個節點之間能互相通信使用靜態IP地址。IP地址和主機名通過/etc/hosts配置，主機名通過/etc/hostname進行配置。

以cm節點（172.31.13.38）為例：

• hostname配置

/etc/hostname文件如下：

ip-172-31-13-38.ap-southeast-1.compute.internal

或者你可以通過命令修改立即生效

[root@ip-172-31-13-38 ~]$ hostnamectl set-hostname ip-172-31-13-38.ap-southeast-1.compute.internal

<font face="微軟雅黑" size=4 color=red >註意：這裏修改hostname跟REDHAT6的區別

• hosts配置

/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
 

以上兩步操作，在集群中其它節點做相應配置。確認需要安裝的4臺主機的hosts文件：

2.2.禁用SELinux

在所有節點執行setenforce 0 命令，此處使用批處理shell執行：

[root@ip-172-31-13-38 ~]$ sh ssh_do_all.sh node.list "setenforce 0"

集群所有節點修改/etc/selinux/config文件如下：

SELINUX=disabled
SELINUXTYPE=targeted

檢查所有機器是否已修改成功：

sh ssh_do_all.sh node.list "cat /etc/selinux/config | grep SELINUX"

2.3.關閉防火墻

集群所有節點執行systemctl stop firewalld命令，此處通過shell批量執行命令如下：

[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"

2.4.集群時鐘同步

在Redhat7.x的操作系統上，已經默認的安裝了chrony，我們這裏先卸載chrony，然後安裝ntp。使用ntp來配置各臺機器的時鐘同步，將cm（172.31.13.38）服務作為本地ntp服務器，其它3臺服務器與其保持同步。

1.所有機器卸載chrony

[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "yum -y remove chrony"

2.所有機器安裝ntp

[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "yum -y install ntp"

3.cm機器配置時鐘與自己同步

[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.集群其它節點，配置找cm機器去同步

#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.重啟所有機器的ntp服務

[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.驗證始終同步，在所有節點執行ntpq -p命令，如下使用腳本批量執行

[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "ntpq -p"

左邊出現*號表示同步成功。

2.5.設置swap

所有節點執行

[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"

2.6.設置透明大頁面

所有節點執行：

[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"

設置開機自關閉

將如下腳本添加到/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

同步到所有節點

2.7.配置操作系統repo

<font face="微軟雅黑" size=4 color=red >Fayson用的是AWS的環境，這步是可以省略的，放在這裏供物理機部署的兄弟們參考。

• 掛載操作系統iso文件

[root@ip-172-31-2-159 ~]$ sudo mkdir /media/DVD1
[root@ip-172-31-2-159 ~]$ sudo mount -o loop 
CentOS-7-x86_64-DVD-1611.iso /media/DVD1/

• 配置操作系統repo

[root@ip-172-31-2-159 ~]$ sudo vim /etc/yum.repos.d/local_os.repo
[local_iso]    
name=CentOS-$releasever - Media
baseurl=file:///media/DVD1
gpgcheck=0
enabled=1
[root@ip-172-31-2-159 ~]$ sudo yum repolist

2.8.安裝http服務

• 安裝httpd服務

[root@ip-172-31-2-159 ~]$ yum -y install httpd

• 啟動或停止httpd服務

[root@ip-172-31-2-159 ~]$ systemctl start httpd
[root@ip-172-31-2-159 ~]$ systemctl stop httpd

• 安裝完httpd後，重新制作操作系統repo，換成http的方式方便其它服務器也可以訪問

[root@ip-172-31-2-159 ~]$ sudo mkdir /var/www/html/iso
[root@ip-172-31-2-159 ~]$ sudo scp -r /media/DVD1/* /var/www/html/iso/
[root@ip-172-31-2-159 ~]$ sudo vim /etc/yum.repos.d/os.repo 
[osrepo]
name=os_repo
baseurl=http://172.31.2.159/iso/
enabled=true
gpgcheck=false
[root@ip-172-31-2-159 ~]$ sudo yum repolist

2.9.安裝MariaDB

1.安裝MariaDB

[root@ip-172-31-13-38 ~]# yum -y install mariadb
[root@ip-172-31-13-38 ~]# yum -y install mariadb-server

2.啟動並配置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

[root@ip-172-31-13-38 ~]# mysql -u root -p
Enter password:
