Viewing the Default User

When MOTService runs the gs_preinstall command to prepare the installation user and environment, the user specified by the -U parameter is the default user and the system administrator. The following describes how to view the default user.

Procedure

Log in to FusionInsight Manager, choose Cluster > Services > MOTService, click Instance, and view and record the service IP address of the MOTServer(Active) instance.
Log in to any MOTService node queried in 1 as user omm.
Run the following command to switch to the MOTService installation directory:

cd $MOTSERVER_HOME
Run the following command to configure environment variables:

source .motservice_profile
Run the following command to log in to MOTService and enter the password of the MOTService database user omm:

gsql -d postgres -p 20105

Contact the system administrator to obtain the password of user omm for the MOTService database.
Run the following command to view the default user:

SELECT rolname FROM pg_authid where oid=10;

The following command output shows that the default user is omm.
```
openGauss=# SELECT rolname FROM pg_authid where oid=10;
 rolname
---------
 omm
(1 row)
```
