參照此博主的博客搭建，本人是3臺虛擬機，按要求配置好hostname以及hosts，ssh等基礎工作。1、虛擬機配置爲：4核8G（定義爲低配，有條件的多加還是比較好）
2、在主服務器上配置HDP的壓縮包，從服務器上部署Mysql或者Maria數據庫，也可以不配置，默認選擇HDP的PostgreSQL數據庫（生產環境不推薦）。
3、儘量選擇離線安裝，HDP壓縮包太大。下載的包放到/var/www/html中。
4、選擇了MySQL數據庫就要在裏面創建表，hive/Oz/superset等在後續安裝中需要database。
5、如果是因爲MySQL的原因，參照此博主博客輸入安裝mysql驅動的命令解決。
6、在安裝過程中出現SSL問題，參考此劉大神博客解決，或次博主https://blog.csdn.net/qq_41805514/article/details/88871477，本人在前兩步完成後解決ssl問題。如果主機安裝還是出現問題，報錯節點找/usr/lib64/python2.7/ssl.py，deafult改成這個PROTOCOL_TLSv1_
二、成功圖片
報錯解決
問題：
DB configs consistency check: no errors and warnings were found.
ERROR: Exiting with exit code 1.
REASON: Server not yet listening on http port 8080 after 50 seconds. Exiting.
方法：
vim /etc/ambari-server/conf/ambari.properties
將以下屬性值增加到120或150秒
server.startup.web.timeout = 120
問題：
部分：

標準錯誤輸出: /var/lib/ambari-agent/data/errors-1312.txt
方法：
Metastore connection URL: jdbc:mysql://hdp001/hive?createDatabaseIfNotExist=true
問題出在URL,hive用戶通過hdp001這臺機器連接mysql需要設置密碼，
前面已經執行過：GRANT ALL PRIVILEGES ON hive.* TO 'hive'@'localhost' IDENTIFIED BY 'hive'; (創建hive用戶)
GRANT ALL PRIVILEGES ON hive.* TO 'hive'@'%' IDENTIFIED BY 'hive';
FLUSH PRIVILEGES; （刷新權限）
已經設置過hive用戶連接的密碼，沒想到還會連接不上
最後執行GRANT ALL PRIVILEGES ON hive.* TO 'hive'@'hdp001' IDENTIFIED BY 'hive',問題解決
問題：Hbase在Ambari中啓動後隨即自動關閉
方法：
ntpd時間，幾臺機器date驗證時間是否一致。
問題：
NameNode Last Checkpoint script alert definition does not trigger based on uncommitted transactions。
報錯誤[Checkpoint Critical]
方法：
sudo su hdfs -l -c 'hdfs dfsadmin -safemode enter'
sudo su hdfs -l -c 'hdfs dfsadmin -saveNamespace'
After that restarting both NameNodes cleared the Alerts.
問題：
Ambari2.4.2 Hbase啓動失敗
HBase Master Process
Connection failed: [Errno 111] Connection refused to bi.corp.mama.cn2:16000
啓動過程是沒有報錯的，都是Success，但是alter提示這個，過一會兒本來Start的HBase Master就自動Stop
辦法：
yum -y install ntp（安裝過的可以直接下一步）
cd /usr/share/zoneinfo/Asia/
ntpdate pool.ntp.org
systemctl start ntpd && systemctl enable ntpd
**SSH上的問題解決辦法要想到各節點之間的免密配置，以及自身0.0.0.0的免密配置。**
**端口上的問題，自建虛擬機不存在，若是阿里雲服務器要在其安全組裏添加端口**
