設置主機名

安裝環境准備工具
其實直接rpm安裝即可，它會自動解決依賴問題包括環境准備工具，但是這樣oracle用戶沒有home目錄，所以單獨先安裝環境准備工具

如果是rhel或者centos，就要手工先下載preinstall的rmp包，然后本地安裝(或者添加oracle linux的yum源來yum安裝)

這默認創建了名為ORCLCDB且pdb名ORCLPDB1的數據庫，當然可以不用這么創建，用傳統的dbca方式
優缺點
實際上這個方式並沒有什么用，比起來靜默安裝也並沒有顯得更容易，只能安裝數據庫軟件，並不能升級數據庫，而且不能用於rac，只能用於安裝單實例數據庫，整個部署沒有給予定制空間比如oracle_home目錄如果和你公司的磁盤規划不一致呢，不過新手可能認為這樣更簡單，這個方式僅試試而已體會一下，實際生產中幾乎是不能用的
