[root@controller ~]# 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!

Nova计算服务

nova-api: 接受响应所有的计算服务请求，管理虚拟机(云主机)生命周期

nova-compute (多个): 真正管理虚拟机(nova-compute调用libvirt)

nova-scheduler: nova调度器（挑选出最合适的nova-compute来创建虚机)

nova-conductor: 帮助nova-compute代理修改数据库中虚拟机的状态

nova-network 早期openstack版本管理虚拟机的网络(已弃用,neutron)

nova-consoleauth和nova-novncproxy: web版的vnc来直接操作云主机

novncproxy: web版vnc客户端

nova-api-metadata: 接受来自虚拟机发送的元数据请求(配合neutron-metadata-agent,来虚拟机定制化)

启动Linuxbridge代理并配置它开机自启动：
	systemctl enable neutron-linuxbridge-agent.service
	systemctl start neutron-linuxbridge-agent.service

Dashboard服务

(根据情况确定安装控制节点还是计算节点）

此次安装在compute上

安装openstack-dashboard

1
yum -y install openstack-dashboard

systemctl restart httpd.service

控制节点

1
systemctl restart memcached.service

###如服务无法启动,在/etc/httpd/conf.d/openstack-dashboard.conf文件下添加以下字段###

​ WSGIApplicationGroup %{GLOBAL}

Cinder块存储服务

cinder-volume LVM,nfs,gfs,ceph

cinder-api: 接收外部的api请求

cinder-volume: 提供存储空间

cinder-scheduler 调度器,决定将要分配的空间由哪一个cinder-volume提供

cinder-backup 备份存储

controller

a.登录mysql数据库
	mysql -u root -p000000
b.创建cinder数据库
	CREATE DATABASE cinder;
c.创建cinder数据库用户，使其可以对cinder数据库有完全控制权限
	GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'CINDER_DBPASS';
	GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'CINDER_DBPASS';
d.退出数据库
	exit
