二.時鍾同步
我們在生產環境中必須同步各個服務器時間是一致的，最好是有內網的時間服務器。 配置時間同步的好處: 可以定位集群故障發生的具體時間; 解決HBase,Kudu等存儲依賴於時間同步的問題(若時間不同步會報錯); CentOS 6.x默認使用ntpd軟件來同步時間的，但在CentOS 7.x版本之后就被更替為chrony來實現時間同步，因此咱們安裝時間同步就是用CentOS 7.x推薦的Chrony來進行時間同步。
1>.安裝chrony
[root@hdp101.yinzhengjie.org.cn ~]# yum -y install chrony Loaded plugins: fastestmirror Determining fastest mirrors * base: mirror.bit.edu.cn * extras: mirror.bit.edu.cn * updates: mirrors.huaweicloud.com ambari-repo | 2.9 kB 00:00:00 base | 3.6 kB 00:00:00 extras | 2.9 kB 00:00:00 mysql-connectors-community | 2.5 kB 00:00:00 mysql-tools-community | 2.5 kB 00:00:00 mysql80-community | 2.5 kB 00:00:00 updates | 2.9 kB 00:00:00 (1/2): extras/7/x86_64/primary_db | 159 kB 00:00:00 (2/2): updates/7/x86_64/primary_db | 5.9 MB 00:00:00 Resolving Dependencies --> Running transaction check ---> Package chrony.x86_64 0:3.4-1.el7 will be installed --> Processing Dependency: libseccomp.so.2()(64bit) for package: chrony-3.4-1.el7.x86_64 --> Running transaction check ---> Package libseccomp.x86_64 0:2.3.1-3.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ============================================================================================================================================================================================================================================================================== Package Arch Version Repository Size ============================================================================================================================================================================================================================================================================== Installing: chrony x86_64 3.4-1.el7 base 251 k Installing for dependencies: libseccomp x86_64 2.3.1-3.el7 base 56 k Transaction Summary ============================================================================================================================================================================================================================================================================== Install 1 Package (+1 Dependent package) Total download size: 306 k Installed size: 788 k Downloading packages: (1/2): libseccomp-2.3.1-3.el7.x86_64.rpm | 56 kB 00:00:00 (2/2): chrony-3.4-1.el7.x86_64.rpm | 251 kB 00:00:00 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Total 957 kB/s | 306 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : libseccomp-2.3.1-3.el7.x86_64 1/2 Installing : chrony-3.4-1.el7.x86_64 2/2 Verifying : libseccomp-2.3.1-3.el7.x86_64 1/2 Verifying : chrony-3.4-1.el7.x86_64 2/2 Installed: chrony.x86_64 0:3.4-1.el7 Dependency Installed: libseccomp.x86_64 0:2.3.1-3.el7 Complete!

2>.禁用本地時間服務器從公網同步時間
[root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf server 0.centos.pool.ntp.org iburst server 1.centos.pool.ntp.org iburst server 2.centos.pool.ntp.org iburst server 3.centos.pool.ntp.org iburst driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# sed -r -i 's@(^server)@#\1@g' /etc/chrony.conf [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]#
3>.新增時間同步服務器為本機地址
[root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# vim /etc/chrony.conf [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf server hdp101.yinzhengjie.org.cn iburst driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]#
4>.設置允許來chronyd服務器端同步時間的客戶端地址
[root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf server hdp101.yinzhengjie.org.cn iburst driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# grep ^#allow /etc/chrony.conf #allow 192.168.0.0/16 [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# sed -r -i 's@#(allow) 192.168.0.0/16@\1 172.200.0.0/21@' /etc/chrony.conf [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# vim /etc/chrony.conf [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf server hdp101.yinzhengjie.org.cn iburst driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync allow 172.200.0.0/21 #允許客戶端IP地址同步 allow 127/8 #允許本地同步時間 logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]#
5>.設置chronyd服務器端允許返回本地時間
[root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf server hdp101.yinzhengjie.org.cn iburst driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync allow 172.200.0.0/21 allow 127/8 logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# grep ^#local /etc/chrony.conf #local stratum 10 [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# sed -r -i 's@#(local)@\1@' /etc/chrony.conf [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/chrony.conf server hdp101.yinzhengjie.org.cn iburst driftfile /var/lib/chrony/drift makestep 1.0 3 rtcsync allow 172.200.0.0/21 allow 127/8 local stratum 10 #即使自己未能通過網絡時間服務器同步到時間，也允許將本地時間作為標准時間授時給其它客戶端，而我們上面設置了禁用默認公網的時間服務器進行同步(換句話說，這里表示不去同步任何服務器的時間)。 logdir /var/log/chrony [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]#
6>.啟動chronyd並設置為開機自啟動
[root@hdp101.yinzhengjie.org.cn ~]# systemctl start chronyd [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# systemctl enable chronyd [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]# systemctl list-unit-files | grep chronyd chronyd.service enabled [root@hdp101.yinzhengjie.org.cn ~]# [root@hdp101.yinzhengjie.org.cn ~]#
7>.查看chronyd正在使用哪個時間服務器進行時間同步

三.部署Ambari集群
1>.瀏覽器訪問"http://hdp101.yinzhengjie.org.cn:8080/",使用默認的用戶名(admin)和密碼(admin)登錄成功后啟動安裝向導(如下圖所示,點擊"LAUNCH INSTALL WIZARD")
2>.自定義集群名稱，並點擊下一步
3>.選擇HDP版本，並選擇本地軟件源倉庫
4>.刪除不相關操作系統的倉庫信息，只保留部署Ambari的操作系統的倉庫信息
5>.注冊主機
6>.確認匹配的主機名稱
7>.等待自動注冊
8>.等待集群自檢
9>.集群自檢完成
如果此步驟和上圖一樣直接跳過下面的閱讀，如果你安裝其它節點存在問題，如下圖所示，別慌，查看日志解決問題才是正道。
查看報錯信息，如下圖所示。
根據報錯信息將hdp101.yinzhengjie.org.cn與hdp[102-103].yinzhengjie.org.cn不同的文件同步后，之前兩個失敗的節點最終狀態變為"Success"狀態。
10>.查看集群自建結果(此步驟可省略，直接進行下一步)
11>.自定義需要安裝的服務(服務勾選少了也沒多大關系,后面可以手動添加服務)
12>.勾選Ambari Metircs(會自動安裝監控已經勾選服務的狀態)服務並點擊"NEXT",如果彈出如下圖所示的提示，點擊"PROCEED ANYWAY"
13>.根據服務器實際資源分配Master服務角色安裝到具體的主機
14>.除了NFSGateway角色(如有需要后續可以自行安裝)不勾選，其它的slave服務都勾選
15>.為Grafana Admin和Activity Explorer's Admin服務設置密碼
16>.自定義各個服務對應數據的存儲路徑(由於我們使用的是root用戶安裝，因此盡管指定的目錄不存在，Ambari會通過root用戶自動創建的喲~)
17>.確認各個服務在操作系統中以哪個用戶身份運行(保持默認即可，直接下一步)
18>.自定義安裝服務的配置並點擊下一步
19>.在Review步驟無需做任何配置，而是對之前幾個步驟的配置有一個大概的信息概覽，如果確認配置五五后點擊"DEPLOY"就正式部署啦
20>.點擊"DEPLOY"會開始初始化任務
21>.初始化完就開始部署了
22>.等待服務自動安裝,啟動和測試
23>.服務安裝成功
24>.安裝完成后點擊上圖的“COMPLETE”會自動進入到"Dashboard"的監控頁面
