ORACLE-BASE - Oracle Database 12c Release 1 (12.1) Installation On Oracle Linux 6

Please click the above link. I used the above link as reference and I have did the following installation in oracle linux 6

I have unziped the linuxamd64_12c_database* to database.

for pre-requiste I simply did 11G pre-requiste and the prequiste completed sucessfully for 12c database install.

so you can go for 

yum install

or

yum install oracle-rdbms-server-11gR2-preinstall -y

running root scripts 

$ su - root
Password: 
[root@ovs1 ~]# /media/12c_db/product/12.1.0/dbhome_1/root.sh
Performing root user operation for Oracle 12c 

The following environment variables are set as:
    ORACLE_OWNER= oracle
    ORACLE_HOME=  /media/12c_db/product/12.1.0/dbhome_1

Enter the full pathname of the local bin directory: [/usr/local/bin]: 
The file "dbhome" already exists in /usr/local/bin.  Overwrite it? (y/n) 
[n]: y
   Copying dbhome to /usr/local/bin ...
