oracle--oracle18C软件安装（一）

一，安装软件

-----------------------------------------------------------------------------------------------------------------

注意：将安装文件解压到Oracle Home下，这里和Oracle 18c之前的版本不同，之前的版本解压的安装文件可以在任何位置，Oracle 解压的安装文件必须在Oracle Home下。因为仅从Oracle home运行runInstaller命令。不要从任何其他位置运行runInstaller。

最好是拷贝到ORACLE_HOME下面后进行一次授权

chomd -R 755 /u01/
