This section describes how to install and configure the freecell service for Red Hat Enterprise Linux 7 and CentOS 7.
Before you install and configure the freecell service, you must create a database, service credentials, and API endpoints.
To create the database, complete these steps:
Use the database access client to connect to the database
server as the root
user:
$ mysql -u root -p
Create the freecell_solver
database:
CREATE DATABASE freecell_solver;
Grant proper access to the freecell_solver
database:
GRANT ALL PRIVILEGES ON freecell_solver.* TO 'freecell_solver'@'localhost' \
IDENTIFIED BY 'FREECELL_SOLVER_DBPASS';
GRANT ALL PRIVILEGES ON freecell_solver.* TO 'freecell_solver'@'%' \
IDENTIFIED BY 'FREECELL_SOLVER_DBPASS';
Replace FREECELL_SOLVER_DBPASS
with a suitable password.
Exit the database access client.
exit;
Source the admin
credentials to gain access to
admin-only CLI commands:
$ . admin-openrc
To create the service credentials, complete these steps:
Create the freecell_solver
user:
$ openstack user create --domain default --password-prompt freecell_solver
Add the admin
role to the freecell_solver
user:
$ openstack role add --project service --user freecell_solver admin
Create the freecell_solver service entities:
$ openstack service create --name freecell_solver --description "freecell" freecell
Create the freecell service API endpoints:
$ openstack endpoint create --region RegionOne \
freecell public http://controller:XXXX/vY/%\(tenant_id\)s
$ openstack endpoint create --region RegionOne \
freecell internal http://controller:XXXX/vY/%\(tenant_id\)s
$ openstack endpoint create --region RegionOne \
freecell admin http://controller:XXXX/vY/%\(tenant_id\)s
Install the packages:
# yum install
Edit the /etc/freecell_solver/freecell_solver.conf
file and complete the following
actions:
In the [database]
section, configure database access:
[database]
...
connection = mysql+pymysql://freecell_solver:FREECELL_SOLVER_DBPASS@controller/freecell_solver
Start the freecell services and configure them to start when the system boots:
# systemctl enable openstack-freecell_solver-api.service
# systemctl start openstack-freecell_solver-api.service
