Red Hat Training
A Red Hat training course is available for Red Hat Virtualization
Appendix E. Preparing a Local Manually-Configured PostgreSQL Database for Use with the Red Hat Virtualization Manager
Optionally configure a local PostgreSQL database on the Manager machine to use as the Manager database. By default, the Red Hat Virtualization Manager's configuration script,
engine-setup
, creates and configures the Manager database locally on the Manager machine. For automatic database configuration, see Section 3.3, “Configuring the Red Hat Virtualization Manager”. To configure the Manager database on a machine that is separate from the machine where the Manager is installed, see Appendix D, Preparing a Remote PostgreSQL Database for Use with the Red Hat Virtualization Manager.
Use this procedure to set up the Manager database with custom values. Set up this database before you configure the Manager; you must supply the database credentials during
engine-setup
. To set up the database, you must first install the rhevm package on the Manager machine; the postgresql-server package is installed as a dependency.
Note
The
engine-setup
and engine-backup --mode=restore
commands only support system error messages in the en_US.UTF8
locale, even if the system locale is different.
The locale settings in the
postgresql.conf
file must be set to en_US.UTF8
.
Important
The database name must contain only numbers, underscores, and lowercase letters.
Procedure E.1. Preparing a Local Manually-Configured PostgreSQL Database for use with the Red Hat Virtualization Manager
- Initialize the PostgreSQL database, start the
postgresql
service, and ensure that this service starts on boot:# su -l postgres -c "/usr/bin/initdb --locale=en_US.UTF8 --auth='ident' --pgdata=/var/lib/pgsql/data/" # systemctl start postgresql.service # systemctl enable postgresql.service
- Connect to the psql command line interface as the
postgres
user:# su - postgres $ psql
- Create a user for the Manager to use when it writes to and reads from the database. The default user name on the Manager is
engine
:postgres=# create role user_name with login encrypted password 'password';
- Create a database in which to store data about the Red Hat Virtualization environment. The default database name on the Manager is
engine
:postgres=# create database database_name owner user_name template template0 encoding 'UTF8' lc_collate 'en_US.UTF-8' lc_ctype 'en_US.UTF-8';
- Connect to the new database and add the
plpgsql
language:postgres=# \c database_name database_name=# CREATE LANGUAGE plpgsql;
- Ensure the database can be accessed remotely by enabling md5 client authentication. Edit the
/var/lib/pgsql/data/pg_hba.conf
file, and add the following line immediately underneath the line starting withlocal
at the bottom of the file:host [database name] [user name] 0.0.0.0/0 md5 host [database name] [user name] ::0/0 md5
- Restart the
postgresql
service:# systemctl restart postgresql.service
Optionally, set up SSL to secure database connections using the instructions at http://www.postgresql.org/docs/8.4/static/ssl-tcp.html#SSL-FILE-USAGE.
