Creating the group informix and user informix (UNIX, Linux)

In a few situations during a root-based installation, you must create the group informix and user informix before you install the database server on UNIX or Linux operating systems.

Before you begin

You must have root authority to create users or groups.

About this task

You must create the objects before you start the installation application in the following situations:

  • You want to specify a particular identifier (ID) number.
  • The group informix exists on the system; however, the user informix does not. In this case, you must create only user informix.

Procedure

To create the objects:
  1. If necessary, create the group informix by using the following command, where n is a unique identifier (ID) greater than 100:
    • AIX: mkgroup -a n informix
    • UNIX, Linux: groupadd -g n informix
  2. Create the user informix by using the useradd command, where n is a unique identifier (ID) greater than 100:
    • useradd -u n -g informix informix
    Important: Add users to the group informix only if the users need administrative access to the database server.
  3. Create a password for user informix by using the passwd command.
