1. Install MariaDB:

   # yum install mariadb mariadb-server MySQL-python
   

2. Set some needed MariaDB configuration parameters:

   # vim /etc/my.cnf
   
     bind-address = 172.16.0.192
     default-storage-engine = innodb
     innodb_file_per_table
     collation-server = utf8_general_ci
     init-connect = 'SET NAMES utf8'
     character-set-server = utf8
   

3. Enable and start the MariaDB service:

   # systemctl enable mariadb.service
   # systemctl start mariadb.service
   

4. Initialize MariaDB security. Say ‘yes’ to all prompts, and set a good root password:

   # mysql_secure_installation
   

5. Set up the MySQL client configuration. Replace *MYSQL_ROOT* with your own:

   # vim /root/.my.cnf
   
     [client]
     user=root
     password=*MYSQL_ROOT*
   

6. Confirm that you are able to connect to MySQL:

   # mysql
   
     > quit
   

7. Install RabbitMQ:

   # yum install rabbitmq-server
   

8. Enable and start the RabbitMQ service:

   # systemctl enable rabbitmq-server.service
   # systemctl start rabbitmq-server.service
   

9. Create the “openstack” RabbitMQ user:

   # rabbitmqctl add_user openstack *RABBIT_PASS*
   # rabbitmqctl set_permissions openstack ".*" ".*" ".*"
