我現在所在的公司用的是CDH管理Hadoop集群，前端時間去面試時發現很多企業都在用HDP，於是回來搗鼓來一下HDP的部署方式。部署時也踩過不少坑，這里把正確部署Ambari的方式記錄一下。其實部署Ambari的方式和CDH的部署方式大同小異。
本片博客會詳細介紹如何使用Ambari來安裝HDP發行版本，想要避免去官網踩坑的小伙伴可以這篇筆記很適合你喲！HDP是Hontorworks Data Platform的簡稱，是Hontorworks公司的Hadoop發行版本，在企業中十分流行。同樣著名的還有Cludera公司的CDH發行版本（詳情請參考我的筆記：離線方式部署Cloudera Manager5.15.1）。
一.Ambari簡介
和CDH一樣，Ambari是一款用於部署，管理和監控Hadoop集群服務的開源系統，它實現來以下功能：
1>.安裝一個Hadoop集群：
第一：提供了以向導指引的方式安裝一個集群，可以在任意的主機上安裝Hadoop服務。
第二：提供了對Hadoop服務的配置功能。
2>.管理一個Hadoop集群：
提供了啟動，停止等集群管理功能。
3>.監控Hadoop集群：
第一：提供了一個監控Hadoop集群監控狀態的儀表盤。
第二：提供了一套監控指標體系來手機監控數據。
第三：提供了一套預警框架，可以結合預定的監控指標實現通知告警。
和CDH很像，從設計上看Ambari使用的Master/Slaves架構（主/從架構，由一個Ambari-Server和多個Agent組成）。如下圖所示，它是通過一個Server主進程來實現集群的管理和操作命令的發送，而具體管理動作則由安裝在每台目標主機上的Agent進程進行執行。例如通過Ambari啟動HDFS服務的時候，首先會由Ambari-Server向安裝來HDFS服務所在主機的Agent進程發送啟動指令，然后再有相關Agent進程執行其所在主機的本地命令來啟動HDFS的相應服務。
二.集群服務規划設計
在正式安裝之前，我們還需要完成一些前期准備工作，包括集群服務的設計，服務器環境准備和用於安裝Ambari的本地yum倉庫等。
yum（全稱為Yellow dog Updater，Modified）是一個在Fedora和RedHat以及CentOS中的Shell前端軟件包管理器。基於RPM包管理，能夠從指定的服務器自動下載RPM包並且安裝，可以自動處理依賴性關系，並且一次安裝所有的以來的軟件包，無須繁瑣地一次次下載，安裝。
在了解了集群服務器角色的職責划分之后，現在可以開始設計以下集群節點的服務划分了。Ambari通過集成HDP這樣一個Hadoop發行版安裝包來實現對應組件服務的安裝。接下來，我們看看截止到HDP2.5版本，它都提供了那些核心服務。
1>.NameNode
分布式文件系統HDFS主控服務，主要用於保存文件系的元數據信息以及操作路由。
2>.SecondNameNode
專職用於幫助NameNode合並快照日志文件的服務，以緩解NameNode壓力。
3>.DataNodes
分布式文件系統HDFS的數據存儲服務，主要你提供文件數據塊的存儲和查詢功能。
4>.ResourceManger
資源調度系統YARN的主控服務，負責統一的資源分配和調度工作。
5>.NodeManagers
資源調度系統YARN的容器服務，負責具體的任務執行工作，YARN只會將任務分配到安裝了NodeManager服務的主機執行任務。
6>.App Timeline Server
負責存儲在YARN中執行任務的歷史信息，包括任務狀態，任務日志等，並提供對這些信息查詢的能力。
7>.Histroy Server
負責存儲在YARN中執行的任務的歷史信息，包括任務狀態，任務日志等，並提供對這些信息查詢的能力。
8>.Hive Metastore
負責存儲數據倉庫Hive的元數據信息，例如表名稱，表字段和字段屬性等。
9>.HiveServer2
Hive在線查詢服務，支持通過JDBC和ODBC等標准協議查詢數據。
10>.Tez
使用DAG作為計算模型的一款分布式計算引擎，HDP版本里Hive組件的計算引擎使用的正式Tez。
11>.Active HBase Master
分布式NoSQL服務，HBase的主控服務，主要負責Region的分配和DDL操作。
12>.RegionServers
分布式NoSQL服務，HBase的數據存儲服務，主要提供具體數據的存儲與查詢功能。
13>.Zookeeper server
分布式協同管理服務，負責HBase，Ambari Infra 和Kafka等多項服務的協同工作。
14>.Kafka Broker
分布式消息系統Kafka，負責消息的接受，發送，消息主題的管理等工作。
15>.Spark History Server
分布式內存計算框架Spark的任務歷史服務，負責存儲記錄Spark任務的歷史信息，包括任務狀態，執行時間，任務日志和環境變量等信息。同時也提供這些歷史細膩下的查看檢索功能。
16>.Spark Thrift Servers
分布式內存計算框架Spark的在線查詢服務，和Hive的HiveServer2服務類似。支持通過JDBC和OBDC等標准協議查詢數據。
17>.Knox Gateway
網關服務，可以代理HDP中YARN，HBase，HDFS等眾多組件的Restful服務。
18>.Ranger Admin
權限管理服務，可以代理YARN，HBase，HDFS等眾多組件的權限管理功能。
19>.Ranger KMS Server
Ranger的Key管理服務，用於管理Hadoop集群的認證密鑰。
20>.Ranger Usersync
Rabfer的用戶同步服務，負責將Hadoop的集群用戶同步更新到Ranger的內部服務。
21>.Zepplin
交互式在線分析工具，可以直接通過Web界面編寫SQL或代碼的形式使用Spark，Hive等服務進行交互式分析。
22>.Log Search
日志采集與分析服務，負責收集所有Hadoop服務的日志文件並提供集中展示和檢索功能。
23>.Ambari Infra
搜索服務，用於存儲Ranger的審計日志以及Log Search采集到的系統日志等數據。
24>.Clients
各種服務的客戶端程序，包括MapReduce2 Clients，YARN Clients，Hive Clients，Zookeeper Clients，Spark Clients，HBase Clients等等。
在了解上述Ambari可以安裝的核心服務之后，我們可以根據服務列表自行添加服務，這和我們之前部署CDH自定義需要安裝服務幾乎如出一轍。想必部署過CDH的小伙伴，對這個理解起來也非常簡單的，我在這里就不多費口舌啦～
三.環境准備
1>.Ambari目前只支持64位的操作系統，具體操作如下：
1.1>.RHEL(Redhat Enterprise Linux)6或者7；
1.2>.CentOS6或者CentOS7；
1.3>.OEL（Oracle Enterprise Linux）6或者7；
1.4>.SLES（SuSE Linux Enterprise Server）11；
1.5>.Debian 7；
1.6>.Ubantu12 或者14；
2>.配置主機列表（每台主機都需要配置，我本次實驗共計3台服務器）
Ambari所管理的各個服務之間需要使用FQDN來進行訪問，所以我們還需要為各個服務器配置他們的FQDN。Linux系統可以通過主機表配置它的 FQDN，編輯“/etc/hosts”這個配置文件即可。
[root@node101 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 172.30.1.101 node101.yinzhengjie.org.cn 172.30.1.102 node102.yinzhengjie.org.cn 172.30.1.103 node103.yinzhengjie.org.cn [root@node101 ~]# [root@node101 ~]#
FQDN（Fully Qualified Domain Name）：
完全合格域名/全稱域名，是指主機名加上全路徑，全路徑中列出了序列中所有域成員。全域名可以從邏輯上准確地表示處主機在什么地方，也可以說全域名是主機名的一種完全表示形式。
我都實驗環境配置了3台服務器，3台服務器都相同，如下圖：
3>.各個主機配置免密登陸（在“node101.yinzhengjie.org.cn”上操作）

4>.編寫集群管理腳本
在配置FQDN和免密鑰登陸后，咱們就可以編寫一些集群的管理腳本，便於我們下發文件到其他節點中。
[root@node101 ~]# vi /usr/local/bin/xcall.sh #我們創建該腳本時，直接就把它放在默認的“PATH”環境變量中。因此編輯好后只要有執行權限就可以在任意路徑調用它啦！ [root@node101 ~]# [root@node101 ~]# [root@node101 ~]# cat /usr/local/bin/xcall.sh #!/bin/bash #@author :yinzhengjie #blog:http://www.cnblogs.com/yinzhengjie #EMAIL:y1053419035@qq.com #判斷用戶是否傳參 if [ $# -lt 1 ];then echo "請輸入參數" exit fi #獲取用戶輸入的命令 cmd=$@ for (( i=101;i<=103;i++ )) do #使終端變綠色 tput setaf 2 echo ============= node${i}.yinzhengjie.org.cn : $cmd ============ #使終端變回原來的顏色，即白灰色 tput setaf 7 #遠程執行命令 ssh node${i}.yinzhengjie.org.cn $cmd #判斷命令是否執行成功 if [ $? == 0 ];then echo "命令執行成功" fi done [root@node101 ~]# [root@node101 ~]# [root@node101 ~]# chmod +x /usr/local/bin/xcall.sh #別忘記添加執行權限喲！ [root@node101 ~]# [root@node101 ~]# xcall.sh cat /etc/redhat-release #我們在這里可以測試一些咱們的腳本是否好使～ ============= node101.yinzhengjie.org.cn : cat /etc/redhat-release ============ CentOS Linux release 7.2.1511 (Core) 命令執行成功 ============= node102.yinzhengjie.org.cn : cat /etc/redhat-release ============ CentOS Linux release 7.2.1511 (Core) 命令執行成功 ============= node103.yinzhengjie.org.cn : cat /etc/redhat-release ============ CentOS Linux release 7.2.1511 (Core) 命令執行成功 [root@node101 ~]# [root@node101 ~]#

5>.本篇博客的操作系統環境如下
由於Ambari是使用Java語言開發實現的，所以其部署的服務還需要安裝Java環境，Ambari支持1.7或者1.8版本。推薦使用1.8版本，因為jdk1.7官網以及不維護了。
大家可以自行去Oracle官網下載相應的jdk，我這里給出下載地址：https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html（推薦下載tar.gz的安裝包）。

如果你的內網有ntpd服務器的話直接修改每台服務器的“/etc/ntp.conf”配置文件即可，將ntpd服務器的IP地址寫進去。如果沒有話，那就自己部署一個即可，詳情請參考：https://www.cnblogs.com/yinzhengjie/p/9480665.html。我這里就是在“node101.yinzhengjie.org.cn”主機上部署了ntp服務器，並修改了以下參數：
然后在“node102.yinzhengjie.org.cn”和“node103.yinzhengjie.org.cn”這2台主機上配置了周期性的計划任務：

四.搭建本地yum源倉庫（實現離線安裝）
安裝Ambari系統本身以及通過Ambari安裝HDP發行版中的Hadoop服務都需要通過yum的方式進行安裝。由於本片博客場景定位的是企業級應用，而企業內部的服務器處於安全考慮通常會通過防火牆隔絕外網環境。就算服務器可以直接聯網，HDP那么多達到數G的安裝包大小也不適合通過互聯網直接安裝。所以需要在局域網搭建一套Ambari和HDP的本地yum源倉庫用於進行安裝。本篇博客將會安裝Ambari2.6.0以及對應的HDP2.6.3.0版本。

大家可以直接在服務端跟我一樣使用wget工具下載，如果網速不好端朋友，可以直接用我已經下載好端軟件，我這里給出百度雲鏈接：
2>.安裝WEB服務器
這里我們可以使用Apache來當作HTTP服務器。當然你也可以用Nginx，由於CentOS的yum源默認就支持可以安裝httpd服務，因此我就偷個懶就直接用httpd吧。

五.安裝ambari-server
1>.安裝postgresql數據庫
和CDH一樣，Ambari默認是使用postgresql數據庫來保存元數據它的元數據信息，這需要咱們運維的小伙伴對postgresql數據庫要具有一定的了解，掌握常見的故障拍錯，包括如何配置數據庫的主從同步等等。有的人沒有懶得去學習也可以使用oracle或者mysql來存放元數據信息，當然，即使你使用來別的數據庫，推薦你依然要配置數據庫的主從同步，目的是防治單點故障嘛，你懂的。因此，我們可以總結一下為什么不實用postgrsql數據庫的原因：
第一：需要學習數據庫的成本提升（主從復制）；
第二：postgresql數據庫的性能我們無法保證，因為我們對他的了解情況不深入；
第三：postgresql數據庫的可靠性我們無法保證！
綜上所述，我們在生產環境中不推薦使用內置的數據庫選項，而是應該使用自己安裝的數據庫（單本篇博客依舊會介紹如何使用postgresql數據庫來安裝Ambari服務。），比如關於如何使用mysql存放Ambari元數據的配置案例請參考：https://www.cnblogs.com/yinzhengjie/p/10074613.html。

第一，是否配置好yum源；
第二：是否安裝來postgresql數據庫（如果沒有安裝psotgresql數據庫的話安裝Ambari-Server是會報錯的）；

4>.配置Ambari-Server
在安裝Ambari-Server之后，如果我們直接跳過當前的步驟，直接去執行第5步驟，我們會發現啟動服務報錯，這是因為在啟動服務之前必須要先完成初始配置，執行ambari-server setup命令開始配置。
[root@node101 ~]# ambari-server setup Using python /usr/bin/python #看到這里的數據，同學們估計已經猜到了，沒錯Ambari-Server會通過Python腳本啟動一個交互式的shell程序來引導用戶完成配置，這和CDH幾乎是如出一轍啊！！！ Setup ambari-server Checking SELinux... #咱們再看看這個輸出，說明程序配置首先會檢查是否已經禁用了SELinux，這項配置在之前步驟已經設置過了，所以下面價差的狀態為“disabled” SELinux status is 'disabled' Customize user account for ambari-server daemon [y/n] (n)? n #緊接着，出現了一個交互的場景，問咱們是否要指定Ambari的用戶，這里用戶使用默認的Amabri用戶，輸入字母“n”，或者直接按回車即可。 Adjusting ambari-server permissions and ownership...

5>.啟動Ambari-Server
我們初始化了Ambari-Server的存放元數據信息的數據庫以及配置jdk等環境后（也就是第4步驟），我們就可以啟動Ambari Serveri數據庫啦！
[root@node101 ~]# ambari-server start #輸入相應的啟動命令，你就會發現啟動數據是成功的 Using python /usr/bin/python Starting ambari-server Ambari Server running with administrator privileges. Organizing resource files at /var/lib/ambari-server/resources... Ambari database consistency check started... Server PID at: /var/run/ambari-server/ambari-server.pid Server out at: /var/log/ambari-server/ambari-server.out Server log at: /var/log/ambari-server/ambari-server.log #這個文件是存放日志的，上面2個文件存放的是PID以及 Waiting for server start...................... Server started listening on 8080 #這里自然就是監聽服務的端口啦～我們可以通過webUI的方式去訪問它。 DB configs consistency check: no errors and warnings were found. Ambari Server 'start' completed successfully. #這里提示我們服務啟動成功啦～ [root@node101 ~]#
好啦，既然服務已經啟動成功了，那我們也別閑着了，說干就干吧，訪問一下WebUI吧：
如上圖所示，登陸系統之后，會看到Ambari空空如也的歡迎界面，接下來我們就需要介紹如何通過Ambari新建Hadoop集群。詳情請參考我的博客：手把手教你通過Ambari新建Hadoop集群圖解案例。
