一鍵準備Oracle安裝

在Linux下安裝Oracle軟件以前,有至關工做須要準備,包括創建用戶、配置內核參數、配置資源限制參數、配置Oracle用戶環境等,十分繁瑣。即使十分熟悉,也須要花費必定的精力來準備。說白了,作這些事情有點相似於低水平重複建設,雖沒有多大技術含量,卻又不得不作。如今將這些準備工做作成腳本,這樣能夠近乎實現一鍵準備Oracle安裝。node

說明:c++

1> 該腳本的執行方式爲sh Oracle_Setup_Prepare.sh orcl /u01,兩個參數說明見腳本解釋部分。數據庫

2> 該腳本中涉及到一個文本文件Package_list,是Oracle安裝依賴包的列表。具體內容以下文所示。bash

3> 該腳本主要針對於單實例數據庫安裝。session

4> 安裝信息可參考生成的output.log文件oracle

腳本內容以下:app

[oracle@node3 ~]$ cat Oracle_Setup_Prepare.sh ui

###功能:Preparation for Oracle Installation
###參數:SID BASE
###其中,sid指的是ORACLE_SID
###BASE指的是ORACLE_BASE的一級目錄,如ORACLE_BASE=/u01/app/oracle,則BASE爲/u01

 PS: 既然sed每次都是在最後一行追加,其實,用echo "***" >> filename便可實現。
