配置http服務(wù)

  1. 查看http服務(wù)documentroot目錄
    默認(rèn)為：/var/www/html
  2. 上傳并解壓安裝包
    將下載的Ambari、HDP、HDP-UTILS安裝包上傳至規(guī)劃的http服務(wù)器documentroot（默認(rèn)：/var/www/html）目錄下
    在documentroot（默認(rèn)：/var/www/html）目錄下創(chuàng)建HDP-UTILS目錄，并將HDP-UTILS-1.1.0.21-centos6.tar.gz移動(dòng)至剛創(chuàng)建的HDP-UTILS目錄下，解壓：tar -zxvf HDP-UTILS-1.1.0.21-centos6.tar.gz
    在documentroot（默認(rèn)：/var/www/html）目錄下解壓Ambari、HDP安裝包：tar -zxvf ambari-2.5.0.3-centos6.tar.gz && tar -zxvf HDP-2.6.0.3-centos6-rpm.tar.gz
  3. 啟動(dòng)httpd服務(wù)
service httpd restart
  1. 驗(yàn)證http服務(wù)
    在瀏覽器中訪問(wèn)如下地址：
    http://192.168.111.135/ambari/centos6
    http://192.168.111.135/HDP/centos6
    http://192.168.111.135/HDP-UTILS
    可獲取相應(yīng)目錄及文件即證明http服務(wù)部署成功

準(zhǔn)備Mysql數(shù)據(jù)庫(kù)

使用Redhat本地源安裝Mysql服務(wù)：yum -y install mysql*
初始化Mysql服務(wù)：/usr/bin/mysql_install_db --defaults-file=/etc/my.cnf --datadir=/var/lib/mysql
啟動(dòng)mysql：service mysqld restart
設(shè)置root賬號(hào)密碼：/usr/bin/mysqladmin -S /var/lib/mysql/mysql.sock -u root password 'root'
登陸mysql開(kāi)放遠(yuǎn)程訪問(wèn)：

#mysql -uroot -proot
>GRANT ALL PRIVILEGES ON *.* TO 'root'@'master01' IDENTIFIED BY 'root' WITH GRANT OPTION;
>GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY 'root' WITH GRANT OPTION;
>FLUSH PRIVILEGES;

安裝Ambari

在規(guī)劃的Ambari-server服務(wù)器上按照提示安裝：

yum -y install ambari-server

設(shè)置Ambari Server

ambari-server setup

注意事項(xiàng)：
jdk選擇1.8
數(shù)據(jù)庫(kù)選擇mysql
數(shù)據(jù)庫(kù)用戶(hù)名密碼root/root
Ambari元數(shù)據(jù)需手工導(dǎo)入mysql數(shù)據(jù)庫(kù)

啟動(dòng)Ambari Server

ambari-server start

安裝HDP服務(wù)

成功啟動(dòng)Ambari Server之后，進(jìn)入頁(yè)面根據(jù)提示安裝服務(wù)組件
服務(wù)組件全部安裝完成之后，會(huì)自動(dòng)啟動(dòng)所有組件，可在Ambari頁(yè)面查看相關(guān)監(jiān)控信息
注意：安裝過(guò)程中如果出現(xiàn)缺少依賴(lài)包的錯(cuò)誤，可根據(jù)日志提示，通過(guò)Redhat本地源或從網(wǎng)絡(luò)下載對(duì)應(yīng)rpm包進(jìn)行安裝

服務(wù)概覽

新特性

Hive View 2.0

  1. QUERY界面
  1. TABLES界面

注意：TABLES界面可以對(duì)hive表元數(shù)據(jù)進(jìn)行編輯操作

  1. SETTINGS界面

注意：SETTINGS界面可以用戶(hù)自定義配置項(xiàng)，且重新登錄后仍然生效

使用Hive View 2.0與之前的Hive View相同，需要關(guān)閉HDFS權(quán)限檢查功能（dfs.permissions.enabled）

  1. 執(zhí)行測(cè)試語(yǔ)句
select tb1.id,count(tb2.id) from dual tb1 join  dual tb2 on tb1.id = tb2.id group by tb1.id order by tb1.id

更完善的Grafana

其它特性有待繼續(xù)研究
