控制节点、网络节点、计算节点：
一、配置源
1.配置EPEL源
yum install http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
2.配置RDO源
yum install http://rdo.fedorapeople.org/openstack-kilo/rdo-release-kilo.rpm
3.升级系统源
yum upgrade
#以下为经注释，均在控制节点操作
二、安装配置数据库
1.安装数据库
yum install mariadb mariadb-server MySQL-python
2.配置数据库
vim /etc/my.cnf.d/mariadb_openstack.cnf [mysqld] ... bind-address = 10.0.0.11 #设置管理IP
#设置参数 default-storage-engine = innodb innodb_file_per_table collation-server = utf8_general_ci init-connect = 'SET NAMES utf8' character-set-server = utf8
3.启动服务，设置开机自启动
systemctl enable mariadb.service
systemctl start mariadb.service
4.初始化数据库
mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] Y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] Y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] Y
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] Y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] Y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
三、安装配置rabbitmq
1.安装rabbitmq
yum install rabbitmq-server
2.启动服务，设置开机自启动
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service
3.Add the openstack user
rabbitmqctl add_user openstack RABBIT_PASS
Replace RABBIT_PASS with a suitable password.
4.Permit configuration, write, and read access for the openstack user
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
