Adding user accounts for Linux systems


Adding user accounts for Linux systems
Prev	Defining DB2 user and group accounts	Next

In the following examples that show creating user accounts, you can use the following options:

The -g option specifies the group
The -u option specifies the user ID
The -d option specifies the home directory
The -m option creates the home directory if it doesn't exist
The -s option is the user's logon shell
The final expression is the user's logon.

Create the user accounts on each node in the cluster.

This example shows how to create the user, db2inst1, who is the DB2 UDB instance owner. The instance's home directory is also the mount point: /db2_mnt/db2inst1. The file system that hosts the DB2 UDB instance home directory on shared storage uses this mount point. The DB2 UDB instance home directory must exist on every node. For example:

# useradd -g db2iadm1 -u 1004 -d /db2_mnt/db2inst1 -m -s 
/bin/ksh/ db2inst1

The following examples show how to create user accounts for db2fenc1 and db2as. These users' home directories are under /home in the local file system on each node.

# useradd -g db2fadm1 -u 1003 -d /home/db2fenc1 -m -s /bin/ksh 
db2fenc1
# useradd -g db2asgrp -u 1002 -d /home/db2as -m -s /bin/ksh db2as
