1.概述
本文檔主要描述離線環境下，CentOS6.5作業系統部署CDH5.12.1企業版的過程。本安裝文檔主要分為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叢集
4.叢集完整性檢查（包括HDFS檔案系統、MapReduce、Hive等服務是否可以正常運作）
這篇文檔将着重介紹Cloudera管理器與CDH的安裝，并基于以下假設：
1.作業系統版本：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.采用root對叢集進行部署
6.您已經下載下傳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
叢集中各個節點之間能互相通信使用靜态IP位址。IP位址和主機名通過/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）。
以伺服器（172.31.6.148）為例：
- hostname配置
修改/etc/sysconfig/network檔案：
[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後需要重新開機伺服器。
檢查hostname是否修改成功：
[root@ip-172-31-6-148~]# hostnameip-172-31-6-148.fayson.com
[root@ip-172-31-6-148 ~]#
- hosts配置
/etc/hosts檔案如下:
[root@ip-172-31-6-148~]# more /etc/hosts127.0.0.1 localhost.localdomain localhost::1 localhost6.localdomain6 localhost6172.31.6.148 ip-172-31-6-148.fayson.com172.31.5.190 ip-172-31-5-190.fayson.com172.31.10.118 ip-172-31-10-118.fayson.com172.31.9.33 ip-172-31-9-33.fayson.com[root@ip-172-31-6-148 ~]#
以上兩步操作，在叢集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 指令
[root@ip-172-31-6-148~]# sudo setenforce 0
修改叢集所有節點的/etc/selinux/config檔案，内容如下：
[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
在叢集所有節點執行如下操作，并永久關閉防火牆
[root@ip-172-31-6-148~]# service iptables stopiptables: 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配置作業系統本地yum源
- 挂載作業系統iso檔案
[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 -hFilesystem 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 ~]#
- 配置作業系統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
檢視yum源清單是否有建立的localrepo
[root@ip-172-31-6-148~]# yum repolistLoaded plugins: fastestmirror, prestoLoading mirror speeds from cached hostfile
* base: mirror.0x.sg
* extras: mirror.0x.sg

2.5安裝http服務
- 使用yum安裝http服務
在叢集其中一節點上安裝http服務，執行如下指令：
[root@ip-172-31-6-148~]# yum -y install httpd
如上圖所示則表明安裝成功。
- 将httpd服務加入系統自啟動服務并設定開機啟動
[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 httpdhttpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off[root@ip-172-31-6-148 ~]#
- 啟動http服務
[root@ip-172-31-6-148~]# service httpd startStarting httpd: [ OK ]
2.6重做作業系統yum源
在2.5安裝了httpd服務後，重新制作作業系統的yum源，使用http的方式，操作如下：
- 在/var/www/html目錄下建立centos6.5目錄
[root@ip-172-31-6-148html]# mkdir centos6.5[root@ip-172-31-6-148 html]# lltotal 4drwxr-xr-x 2 rootroot 4096 Sep 4 16:04 centos6.5[root@ip-172-31-6-148 html]#
- 将/mnt/iso目錄下的所有檔案拷貝至/var/www/html/centos6.5目錄下
[root@ip-172-31-6-148html]# 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
将/etc/yum.repo.d/os.repo配置檔案同步到叢集所有節點的/etc/yum.repo.d/目錄下
2.7叢集時鐘同步
在叢集的所有伺服器上安裝ntp服務，用于叢集時鐘同步，此處選擇ip-172-31-6-148.fayson.com伺服器作為本地NTP伺服器，叢集其它節點與其保持同步，配置如下：
- 在叢集所有節點安裝ntp服務，指令如下
[root@ip-172-31-6-148~]# yum -y install ntp
如上圖顯示，則說明安裝成功。
- 将ntpd加入系統自啟動服務并設定開機啟動
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 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburstserver 127.127.1.0 #local clockfudge 127.127.1.0 stratum 10
- 叢集其它節點配置如下
[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 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburstserver 172.31.6.148 iburst
- 重新開機叢集所有節點的ntpd服務
[root@ip-172-31-6-148~]# service ntpd restartShutting 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指令
[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。
- 将mysqld加入系統自啟動服務并設定開機啟動
[root@ip-172-31-6-148~]# chkconfig --add mysqld[root@ip-172-31-6-148 ~]# chkconfig mysqld on
- 啟動并配置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, andyou 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] yNew 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 MySQLinstallation should now be secure.Thanks for usingMySQL!
[root@ip-172-31-6-148 ~]#
注意：标紅部分為輸入項，出現“Thanks for using MySQL!”則表示初始化成功。
