Installing Oracle Weblogic 14c (14.1.1) in linux.

Creating users and groups

As root, run the following commands to create the Oracle user and groups:

# sudo -i

The below commands must be executed as root.

Add the groups required by Oracle.

Create the Oracle Inventory group:

# groupadd oinstall

Create the Oracle DBA group:

# groupadd dba

Create the home directory for the Oracle user:

# mkdir /home/oracle/

Create the directory for installing Oracle:

# mkdir -p /u01/app/oracle

Then create the Oracle user account that is a member of the dba group, has the /home/oracle/ home directory and uses /bin/bash as the default shell:

# useradd -g oinstall -G dba -d /home/oracle -s /bin/bash oracle

Set the password for the oracle user (don’t forget this password):

# passwd oracle

Set the oracle user as the owner of the Oracle home directory and Oracle installation directory. The oracle user is a member of the oinstall group.

# chown -R oracle:oinstall /home/oracle

# chown -R oracle:oinstall /u01/app/oracle

Create the directory for Oracle Inventory:

# mkdir -p /u01/app/oraInventory

Set the oracle user as the owner for the Oracle Inventory directory:

# chown -R oracle:oinstall /u01/app/oraInventory

# chmod -R 775 /u01
