安装oracle相关的依赖包：

1	[iyunv@rac12c1 ~]# yum install oracle-rdbms-server-12cR1-preinstall –y

创建用户组和用户，上步操作依据创建了oinstall 54321 dba 54322用户组）和用户oracle（54321），所以执行如下操作创建相关的用户组和用户

添加组

[iyunv@rac12c1 ~]# groupadd -g 54323 oper [iyunv@rac12c1 ~]#  groupadd -g 54325 asmdba [iyunv@rac12c1 ~]# groupadd -g 54328 asmadmin [iyunv@rac12c1 ~]# groupadd -g 54329 asmoper

添加grid用户

1	[[iyunv@rac12c1 ~]# useradd -u 54322 -g oinstall -G dba,asmdba,asmadmin,asmoper grid

为oracle和grid用户设置密码

1 2	[[iyunv@rac12c1 ~]#passwd oracle [iyunv@rac12c1 ~]# passwd grid

确保oracle是oper，asmdba组成员

1	[iyunv@rac12c1 ~]#  usermod  -g oinstall -G dba,oper,asmdba oracle
