Create Oracle user
Oracle cannot be installed under the root account, so you need to create a user specifically for the installation of Oracle, and you need to create the dba and oinstall user groups.
[root@localhost oracle]#groupadd dba
[root@localhost oracle]#groupadd oinstall
The following commands will create the dba and oinstall user groups:
The following command will create the oracle user and set the password
[root@localhost oracle]#useradd -g oinstall -G dba oracle
[root@localhost oracle]#passwd oracle
Changing password for user oracle.
New UNIX password: [Type password here]
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password: [Type password again here]
passwd: all authentication tokens updated successfully.
The following command will assign the oracle installation directory (/opt/oracle) to the oracle user oinstall user group
[root@localhost oracle]#chown –R oracle:oinstall /opt/oracle
