Oracle單實例安裝環境一鍵配置腳本（CentOS6 + 11gR2 ）

摘要：這是自己曾經寫的一個在服務器上，一鍵配置安裝環境的腳本，能快速完成安裝前環境的配置。

這是自己曾經寫的一個oracle 11gR2在CentOS6 x86_64服務器上，一鍵配置安裝環境的腳本，能快速完成安裝前環境的配置。

具體完成以下工作：

備份系統配置文件，以防出錯

添加oracle用戶和用戶組

創建安裝目錄

關閉selinux

在.bash_profile中修改環境變量

修改sysctl.conf文件

修改limits.conf文件

修改PAM的login文件

安裝必要的依賴包

使用注意事項：

root的用戶執行，chmod +x oraclePreInstCheck.sh

./oraclePreInstCheck.sh運行后，請仔細閱讀說明，再決定是否使用該腳本

該腳本默認參數適用于2核4G內存的環境，你可以根據需要修改kernelset()部分

執行完后，你檢查一下你的安裝目錄及權限（默認/db/oracle）

該腳本會有提示輸入的地方，請不要挑戰它的健壯性，比如輸入安裝根目錄時，不要帶入空格

腳本只需執行一次，修改系統參數如sysctl.conf之前，都有備份成xxx.ora_bak

請確保可以通過yum方式安裝軟件包（使用掛載DVD鏡像或聯網）

建議結合tee將執行過程記錄在日志文件中，./oraclePreInstCheck.sh | tee oraclePreInstCheck.log
