CentOS 7 安装配置oracle 12c数据库

PC环境：
CentOS-7-x86_64-Everything-1503-01.iso
linuxamd64_12102_database_1of2.zip
linuxamd64_12102_database_2of2.zip

安装界面中文乱码参考：http://xiongjiajia.iteye.com/blog/2226155

注意事项：
1.路径和文件夹不要有空格！
2.注意.bash_profile文件的配置,每个人的路径不同 !
3.记录下给oracle装到哪个地方了，.bash_profile配置文件要用



界面安装完成之后进行下面配置
