1.概述
本文檔主要描述離線環境下，CentOS6.5操作系統部署CDH5.12.1企業版的過程。本安裝文檔主要分爲4個步驟：
1.前期準備（包括hostname、關閉防火牆、關閉SELinux、時鐘同步等）
2.安裝Cloudera Manager Server
3.安裝CDH集羣
4.集羣完整性檢查（包括HDFS文件系統、MapReduce、Hive等服務是否可以正常運行）
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：CentOS6.5
2.MySQL版本：5.1.73
3.CM版本：CM 5.12.1
4.CDH版本：CDH 5.12.1
5.採用root對集羣進行部署
6.您已經下載CDH和CM的安裝包（CDH使用parcels包方式安裝）
2.前期準備
2.1hostname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（推薦hostname使用FQDN完全域名的方式配置）。
以服務器（172.31.6.148）爲例：
- hostname配置
修改/etc/sysconfig/network文件：
[root@ip-172-31-6-148~]# vim /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=ip-172-31-6-148.fayson.com
注意：修改hostname後需要重啓服務器。
檢查hostname是否修改成功：
[root@ip-172-31-6-148~]# hostname
ip-172-31-6-148.fayson.com
[root@ip-172-31-6-148 ~]#
- hosts配置
/etc/hosts文件如下:
[root@ip-172-31-6-148~]# more /etc/hosts
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
172.31.6.148 ip-172-31-6-148.fayson.com
172.31.5.190 ip-172-31-5-190.fayson.com
172.31.10.118 ip-172-31-10-118.fayson.com
172.31.9.33 ip-172-31-9-33.fayson.com
[root@ip-172-31-6-148 ~]#
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
[root@ip-172-31-6-148~]# sudo setenforce 0
修改集羣所有節點的/etc/selinux/config文件，內容如下：
[root@ip-172-31-6-148~]# vim /etc/selinux/config
This file controls the state ofSELinux on the system.
SELINUX= can take one of these three values:
enforcing - SELinux security policyis enforced.
permissive - SELinux printswarnings instead of enforcing.
disabled - No SELinux policy isloaded.
SELINUX=disabled
SELINUXTYPE= can take one of these twovalues:
targeted - Targeted processes areprotected,
mls - Multi Level Securityprotection.
SELINUXTYPE=targeted
2.3關閉防火牆
在集羣所有節點執行如下操作，並永久關閉防火牆
[root@ip-172-31-6-148~]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
[root@ip-172-31-6-148 ~]# chkconfig iptables off
[root@ip-172-31-6-148 ~]#
2.4配置操作系統本地yum源
- 掛載操作系統iso文件
[root@ip-172-31-6-148~]# mkdir /mnt/iso
[root@ip-172-31-6-148 ~]# mount -o loop CentOS-6.5-x86_64-minimal.iso/mnt/iso/
[root@ip-172-31-6-148 ~]# df -h
Filesystem Size UsedAvail Use% Mounted on
/dev/xvde 99G 3.4G 91G 4% /
tmpfs 7.4G 0 7.4G 0%/dev/shm
/root/CentOS-6.5-x86_64-minimal.iso 398M 398M 0 100% /mnt/iso
[root@ip-172-31-6-148 ~]#
- 配置操作系統repo
[root@ip-172-31-6-148~]# vim /etc/yum.repos.d/os.repo
localrepo
name=CentOS6.5
baseurl=file:///mnt/iso
gpgcheck=false
enabled=true
查看yum源列表是否有新建的localrepo
[root@ip-172-31-6-148~]# yum repolist
Loaded plugins: fastestmirror, presto
Loading mirror speeds from cached hostfile

repolist: 7,602
[root@ip-172-31-6-148 ~]#
2.5安裝http服務
- 使用yum安裝http服務
在集羣其中一節點上安裝http服務，執行如下命令：
[root@ip-172-31-6-148~]# yum -y install httpd
如上圖所示則表明安裝成功。
- 將httpd服務加入系統自啓動服務並設置開機啓動
[root@ip-172-31-6-148~]# chkconfig --add httpd
[root@ip-172-31-6-148 ~]# chkconfig httpd on
[root@ip-172-31-6-148 ~]# chkconfig --list |grep httpd
httpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[root@ip-172-31-6-148 ~]#
- 啓動http服務
[root@ip-172-31-6-148~]# service httpd start
Starting httpd: [ OK ]
2.6重做操作系統yum源
在2.5安裝了httpd服務後，重新制作操作系統的yum源，使用http的方式，操作如下：
- 在/var/www/html目錄下創建centos6.5目錄
_root@ip-172-31-6-148_html# mkdir centos6.5
[root@ip-172-31-6-148 html]# ll
total 4
drwxr-xr-x 2 rootroot 4096 Sep 4 16:04 centos6.5
[root@ip-172-31-6-148 html]#
- 將/mnt/iso目錄下的所有文件拷貝至/var/www/html/centos6.5目錄下
_root@ip-172-31-6-148_html# scp -r /mnt/iso/*/var/www/html/centos6.5/
- 修改/etc/yum.repo.d/os.repo配置
[root@ip-172-31-6-148~]# vim /etc/yum.repos.d/os.repo
localrepo
name=CentOS6.5
baseurl=http://ip-172-31-6-148.fayson.com/centos6.5
gpgcheck=false
enabled=true
- 檢查yum源是否配置正常
將/etc/yum.repo.d/os.repo配置文件同步到集羣所有節點的/etc/yum.repo.d/目錄下
2.7集羣時鐘同步
在集羣的所有服務器上安裝ntp服務，用於集羣時鐘同步，此處選擇ip-172-31-6-148.fayson.com服務器作爲本地NTP服務器，集羣其它節點與其保持同步，配置如下：
- 在集羣所有節點安裝ntp服務，命令如下
[root@ip-172-31-6-148~]# yum -y install ntp
如上圖顯示，則說明安裝成功。
- 將ntpd加入系統自啓動服務並設置開機啓動
在所有節點執行如下操作：
[root@ip-172-31-6-148~]# chkconfig --add ntpd
[root@ip-172-31-6-148 ~]# chkconfig ntpd on
- 在ip-172-31-6-148.fayson.com上配置與自己同步
[root@ip-172-31-6-148~]# vim /etc/ntp.conf
...
Use public servers from thepool.ntp.org project.
Please consider joining the pool (http://www.pool.ntp.org/join.html).
#server 0.centos.pool.ntp.org iburst
#server 1.centos.pool.ntp.org iburst

#server 3.centos.pool.ntp.org iburst
server 127.127.1.0 #local clock
fudge 127.127.1.0 stratum 10
- 集羣其它節點配置如下
[root@ip-172-31-5-190~]# vim /etc/ntp.conf
...
Use public servers from thepool.ntp.org project.
Please consider joining the pool (http://www.pool.ntp.org/join.html).

#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst
server 172.31.6.148 iburst
- 重啓集羣所有節點的ntpd服務
[root@ip-172-31-6-148~]# service ntpd restart
Shutting down ntpd: [ OK ]
Starting ntpd: [ OK ]
[root@ip-172-31-6-148 ~]#
- 驗證時鐘同步，在所有節點執行ntpq -p命令
[root@ip-172-31-6-148~]# ntpq -p

2.8安裝MySQL
- 安裝MySQL
[root@ip-172-31-6-148~]# yum -y install mysql mysql-server
如上截圖則表示MySQL安裝成功。
- 將mysqld加入系統自啓動服務並設置開機啓動
[root@ip-172-31-6-148~]# chkconfig --add mysqld
[root@ip-172-31-6-148 ~]# chkconfig mysqld on
- 啓動並配置Mysql
[root@ip-172-31-6-148~]# service mysqld start
...
[ OK ]
Starting mysqld: [ OK ]
- 初始化MySQL
[root@ip-172-31-6-148~]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTIONUSE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the passwordwill 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 MySQL
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 MySQL installation has an anonymous user, allowing anyone
to log into MySQL 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 removethem 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, MySQL comes with a database named 'test' that anyone can
access. This is also intended only fortesting, 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 MySQL
installation should now be secure.
Thanks for usingMySQL!
[root@ip-172-31-6-148 ~]#
注意：標紅部分爲輸入項，出現“Thanks for using MySQL!”則表示初始化成功。
