基础软件包的安装

安装openstack仓库
[root@master1 yum.repos.d]# yum install -y centos-release-openstack-mitaka
安装openstack客户端
[root@master1 yum.repos.d]# yum install -y python-openstackclient
安装openstack SElinux管理包
[root@master1 yum.repos.d]# yum install -y openstack-selinux

Mysql数据库部署
#状态数据存放于mysql
[root@master1 yum.repos.d]# yum install -y mariadb mariadb-server python2-PyMysql

#消息代理rabbitmq
[root@master1 yum.repos.d]# 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
[root@master1 yum.repos.d]# yum install -y openstack-keystone httpd mod_wsgi memcached python-memcached


数据库操作：
0）[root@master1 my.cnf.d]# 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
[root@master1 ~]# more /tmp/mysql.sql 
drop database keystone;
create database keystone;
grant all on keystone.* to 'keystone'@'localhost' identified by 'keystone';
grant all on keystone.* to 'keystone'@'%' identified by 'keystone';

drop database glance;
create database glance;
grant all on glance.* to 'glance'@'localhost' identified by 'glance';
grant all on glance.* to 'glance'@'%' identified by 'glance';

drop database glance;
create database nova;
grant all on nova.* to 'nova'@'localhost' identified by 'nova';
grant all on nova.* to 'nova'@'%' identified by 'nova';


create database nova_api;
grant all on nova_api.* to 'nova'@'localhost' identified by 'nova';
grant all on nova_api.* to 'nova'@'%' identified by 'nova';

create database neutron;
grant all on neutron.* to 'neutron'@'localhost' identified by 'neutron';
grant all on neutron.* to 'neutron'@'%' identified by 'neutron';

yum install -y rabbitmq-server  #安装
systemctl enable rabbitmq-server.service #开机自启
systemctl start rabbitmq-server.service  #启动
rabbitmqctl add_user openstack openstack  #新建用户并赋予权限
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
[root@master1 mnesia]# rabbitmq-plugins list
[root@master1 mnesia]# rabbitmq-plugins enable rabbitmq_management #开启rabbitmq的web管理界面

[root@master1 mnesia]# grep '^[a-z]' /etc/keystone/keystone.conf
