[root@elephant x86_64]# service cloudera-scm-server-db start
The files belonging to this database system will be owned by user "cloudera-scm".
This user must also own the server process.

The database cluster will be initialized with locale en_US.UTF8.
The default text search configuration will be set to "english".
