安裝成功！
2、配置ambari-server
檢查SELinux是否關閉：
這裡的狀態是關閉的，繼續進行下一步。
使用指定的使用者：
輸入:no，
輸入:hadoop
輸入no，輸入hadoop使用者
檢查防火牆：
這裡我們的防火牆是關閉的，進行下一步
檢查JDK
這裡我們選擇自己安裝的JDK
選擇:3
輸入JDK的安裝路徑:/usr/local/jdk1.8
GPL License
選擇下載安裝GPL License
輸入：y
資料庫配置
這裡我們選擇內建的PostgreSQL資料庫
輸入：n
[[email protected] root]$ sudo service ambari-server setup
Using python /usr/bin/python
