基础软件包的安装
安装openstack仓库
# yum install -y centos-release-openstack-mitaka
安装openstack客户端
# yum install -y python-openstackclient
安装openstack SElinux管理包
# yum install -y openstack-selinux
Mysql数据库部署
#状态数据存放于mysql
# yum install -y mariadb mariadb-server python2-PyMysql
#消息代理rabbitmq
# yum install -y rabbitmq-server
# Openstack验证服务keystone 其中openstack-keystone是基础包 httpd是web服务器 wsgi是Python的网关接口 memcached存放token的缓存 Python-memcached是Python连接memcached的包
# yum install -y openstack-keystone httpd mod_wsgi memcached python-memcached
数据库操作：
0）# mysql_secure_installation #设置密码，删除测试库等
1）创建以下文件并导入数据库
# more /tmp/mysql.sql
