1.概述

本文檔描述CENTOS7.2操作系統部署CDH企業版的過程。Cloudera企業級數據中心的安裝主要分爲4個步驟：

1.集羣服務器配置，包括安裝操作系統、關閉防火牆、同步服務器時鐘等；
2.外部數據庫安裝
3.安裝Cloudera管理器；
4.安裝CDH集羣；
5.集羣完整性檢查，包括HDFS文件系統、MapReduce、Hive等是否可以正常運行。

這篇文檔將着重介紹Cloudera管理器與CDH的安裝，並基於以下假設：

1.操作系統版本：CENTOS7.2
2.MariaDB數據庫版本爲10.2.1
3.CM版本：CDH 5.10.0
4.CDH版本：CDH 5.10.0
5.採用ec2-user對集羣進行部署
6.您已經下載CDH和CM的安裝包

2.前期準備

2.1.hostname及hosts配置

集羣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/etc/hostname進行配置。

以cm節點（172.31.2.159）爲例：

hostname配置

/etc/hostname文件如下：

ip-172-31-2-159

或者你可以通過命令修改立即生效

ec2-user@ip-172-31-2-159 ~$ sudo hostnamectl  set-hostname ip-172-31-2-159

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

hosts配置

/etc/hosts文件如下:

172.31.2.159 ip-172-31-2-159
172.31.12.108 ip-172-31-12-108
172.31.5.236 ip-172-31-5-236
172.31.7.96 ip-172-31-7-96

以上兩步操作，在集羣中其它節點做相應配置。

2.2.禁用SELinux

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

ec2-user@ip-172-31-2-159 ~$ sh ssh\_do\_all.sh  node.list "sudo setenforce 0"

集羣所有節點修改/etc/selinux/config文件如下：

SELINUX=disabled
SELINUXTYPE=targeted

2.3.關閉防火牆

集羣所有節點執行 sudo systemctl stop命令，此處通過shell批量執行命令如下：

[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh node.list "sudo systemctl stop firewalld"
[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh node.list "sudo systemctl disable firewalld"
[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh node.list "sudo systemctl status firewalld"

2.4.集羣時鐘同步

在CentOS7.2的操作系統上，已經默認的安裝了chrony，配置chrony時鐘同步，將cm（172.31.2.159）服務作爲本地chrony服務器，其它3臺服務器與其保持同步，配置片段：

172.31.2.159配置與自己同步

[ec2-user@ ip-172-31-2-159 ~]$ sudo vim /etc/chrony.conf
server ip-172-31-2-159 iburst
#keyfile=/etc/chrony.keys

集羣其它節點：在註釋下增加如下配置

[ec2-user@ip-172-31-12-108 ~]$ sudo vim /etc/chrony.conf
# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).
server ip-172-31-2-159 iburst
#keyfile=/etc/chrony.keys

重啓所有機器的chrony服務

[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh node.list "sudo systemctl restart chronyd"

驗證始終同步，在所有節點執行chronycsources命令，如下使用腳本批量執行

[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh node.list "chronyc sources"

2.5.配置操作系統repo

掛載操作系統iso文件

[ec2-user@ip-172-31-2-159 ~]$ sudo mkdir /media/DVD1
[ec2-user@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

[ec2-user@ip-172-31-2-159 ~]$ sudo vim /etc/yum.repos.d/local_os.repo
[local_iso] 
name=CentOS-$releasever - Media
baseurl=file:///media/DVD1
gpgcheck=0
enabled=1
[ec2-user@ip-172-31-2-159 ~]$ sudo yum repolist

2.6.安裝http服務

安裝httpd服務

[ec2-user@ip-172-31-2-159 ~]$ sudo yum -y install httpd

啓動或停止httpd服務

[ec2-user@ip-172-31-2-159 ~]$ sudo systemctl start httpd
[ec2-user@ip-172-31-2-159 ~]$ sudo 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

[ec2-user@ip-172-31-2-159 ~]$ sudo mkdir /var/www/html/iso
[ec2-user@ip-172-31-2-159 ~]$ sudo scp -r /media/DVD1/* /var/www/html/iso/
[ec2-user@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
[ec2-user@ip-172-31-2-159 ~]$ sudo yum repolist

2.7.安裝MariaDB

由於centos7默認使用的是5.5.52版本的MariaDB，此處使用的10.2.1版本，點擊，在官網下載rpm安裝包：

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

將包下載到本地，放在同一目錄，執行createrepo命令生成rpm元數據。

此處使用apache2，將上述mariadb10.2.1目錄移動到/var/www/html目錄下, 使得用戶可以通過HTTP訪問這些rpm包。

[ec2-user@ip-172-31-2-159 ~]$ sudo mv mariadb10.2.1 /var/www/html/

安裝MariaDB依賴

[ec2-user@ip-172-31-2-159 ~]$ yum install libaio perl perl-DBI perl-Module-Pluggable perl-Pod-Escapes perl-Pod-Simple perl-libs perl-version

製作本地repo

[ec2-user@ip-172-31-2-159 ~]$ sudo vim /etc/yum.repos.d/mariadb.repo 
[mariadb]
name = MariaDB
baseurl = http://172.31.2.159/ mariadb10.2.1
enable = true
gpgcheck = false
[ec2-user@ip-172-31-2-159 ~]$ sudo yum repolist

安裝MariaDB

[ec2-user@ip-172-31-2-159 ~]$ sudo yum -y install MariaDB-server MariaDB-client

啓動並配置MariaDB

[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!

3.Cloudera Manager安裝

3.1.配置本地repo源

將Cloudera Manager安裝需要的7個rpm包下載到本地，放在同一目錄，執行createrepo命令生成rpm元數據。

[ec2-user@ip-172-31-2-159 cm]$ ls
cloudera-manager-agent-5.10.0-1.cm5100.p0.85.el7.x86_64.rpm

配置Web服務器

此處使用apache2，將上述cdh5.10.0/cm5.10.0目錄移動到/var/www/html目錄下, 使得用戶可以通過HTTP訪問這些rpm包。
```
[ec2-user@ip-172-31-2-159 ~]$ sudo mv cdh5.10.0/ cm5.10.0/ /var/www/html/
```

製作Cloudera Manager的repo源

[ec2-user@ip-172-31-2-159 ~]$ sudo vim /etc/yum.repos.d/cm.repo 
[cmrepo]
name = cm_repo
baseurl = http://172.31.2.159/cm5.10.0.0
enable = true
gpgcheck = false
[ec2-user@ip-172-31-2-159 yum.repos.d]$ sudo yum repolist

驗證安裝JDK

[ec2-user@ip-172-31-2-159 ~]$ sudo yum -y install oracle-j2sdk1.7-1.7.0+update67-1

3.2 安裝Cloudera Manager Server

通過yum安裝ClouderaManager Server

[ec2-user@ip-172-31-2-159 ~]$ sudo yum -y install cloudera-manager-server

初始化數據庫

[ec2-user@ip-172-31-2-159 ~]$ sudo /usr/share/cmf/schema/scm_prepare_database.sh mysql cm cm password

5.Kudu安裝

CDH從5.10開始，打包集成Kudu1.2，並且Cloudera正式提供支持。這個版本開始Kudu的安裝較之前要簡單很多，省去了Impala_Kudu，安裝完Kudu，Impala即可直接操作Kudu。

以下安裝步驟基於用戶使用Cloudera Manager來安裝和部署Kudu1.2

5.1.安裝csd文件

1.下載csd文件

[root@ip-172-31-2-159 ~]# wget http://archive.cloudera.com/kudu/csd/KUDU-5.10.0.jar

2.將下載的jar包文件移動到/opt/cloudera/csd目錄

[root@ip-172-31-2-159 ~]# mv KUDU-5.10.0.jar /opt/cloudera/csd

3.修改權限

[root@ip-172-31-2-159 ~]# chown cloudera-scm:cloudera-scm /opt/cloudera/csd/KUDU-5.10.0.jar 
[root@ip-172-31-2-159 ~]# chmod 644 /opt/cloudera/csd/KUDU-5.10.0.jar

4.重啓Cloudera Manager服務

[root@ip-172-31-2-159 ~]# systemctl restart cloudera-scm-server

5.2.安裝Kudu服務

1.下載Kudu服務需要的Parcel包

[root@ip-172-31-2-159 ~]# wget http://archive.cloudera.com/kudu/parcels/5.10/KUDU-1.2.0-1.cdh5.10.1.p0.66-el7.parcel
[root@ip-172-31-2-159 ~]# wget http://archive.cloudera.com/kudu/parcels/5.10/KUDU-1.2.0-1.cdh5.10.1.p0.66-el7.parcel.sha1
[root@ip-172-31-2-159 ~]# wget http://archive.cloudera.com/kudu/parcels/5.10/manifest.json

2.將Kudu的Parcel包部署到http服務

[root@ip-172-31-2-159 ~]# mkdir kudu1.2
[root@ip-172-31-2-159 ~]# mv KUDU-1.2.0-1.cdh5.10.1.p0.66-el7.parcel* kudu1.2/
[root@ip-172-31-2-159 ~]# mv manifest.json kudu1.2
[root@ip-172-31-2-159 ~]# mv kudu1.2/ /var/www/html/
[root@ip-172-31-2-159 ~]# systemctl start httpd

3.檢查http顯示Kudu正常：

4.通過CM界面配置Kudu的Parcel地址，並下載，分發，激活Kudu。

5.通過CM安裝Kudu1.2

添加Kudu服務

選擇Master和Tablet Server

配置相應的目錄，<font face="微軟雅黑" size=4 color=red >注：無論是Master還是Tablet根據實際情況數據目錄(fs_data_dir)應該都可能有多個，以提高併發讀寫，從而提高Kudu性能

啓動Kudu服務

安裝完畢

5.3.配置Impala

在CDH5.10中，安裝完Kudu1.2後，默認Impala即可直接操作Kudu進行SQL操作，但爲了省去每次建表都需要在TBLPROPERTIES中添加kudu_master_addresses屬性，建議在Impala的高級配置Kudu Master的地址：

--kudu\_master\_hosts=ip-172-31-2-159:7051

6.快速組件服務驗證

6.1.HDFS驗證(mkdir+put+cat+get)

[root@ip-172-31-2-159 ~]# hadoop fs -mkdir -p /lilei/test_table
