[Centos7/Openstack]OpenstackNOVA

Controller

 

Prerequisite

1. To create the databases, complete these steps

[root@controller ~]# mysql -u root -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 9
Server version: 10.1.20-MariaDB MariaDB Server

Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]>

Use the database access client to connect to the database server as the root user

 

MariaDB [(none)]> CREATE DATABASE nova_api;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> CREATE DATABASE nova;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> CREATE DATABASE nova_cell0;
Query OK, 1 row affected (0.00 sec)

Create the nova_api, nova, and nova_cell0 databases

 

 

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \
    ->   IDENTIFIED BY 'dkagh1.';
Query OK, 0 rows affected (0.01 sec)


MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \
    ->   IDENTIFIED BY 'dkagh1.'
    -> ;
Query OK, 0 rows affected (0.00 sec)


MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \
    ->   IDENTIFIED BY 'NOVA_DBPASS';
Query OK, 0 rows affected (0.00 sec)


MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \
    ->   IDENTIFIED BY 'dkagh1.';
Query OK, 0 rows affected (0.00 sec)


MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' \
    ->   IDENTIFIED BY 'dkagh1.';
Query OK, 0 rows affected (0.00 sec)


MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' \
    ->   IDENTIFIED BY 'dkagh1.';
Query OK, 0 rows affected (0.00 sec)

Grant proper access to the databases. Replace dkagh1. with a suitable password.

I set a NOVA_DBPASS to dkagh1. 

Then exit the databases access client.

 

 

2. Source the admin credentials to gain access to admin-only CLI connamd

 

3. Create the Compute service credentials
