系统版本 centos7 （最小化安装即可）
2台机器 内存2g（控制节点建议可以给到4-6g，因为2g我试验起来感觉比较卡顿，dashboard感觉反应有些缓慢），cpu2个 硬盘100g，每台机器需要2个网卡，具体可以查看
说明：
下面是官方截图：

openstack官网 配置说明
openstack安装步骤：
1.[ntp安装]
ntp主要为同步时间所用，时间不同步，可能造成你不能创建云主机
yum install chrony
vi /etc/chrony.conf增加
server NTP_SERVER iburst
allow 你的ip地址网段（允许你的ip地址网段可以访问ntp）
systemctl enable chronyd.service(加入系统自启动)
systemctl start chronyd.service（启动ntp服务）
注意：在centos7以前的版本安装ntp
yum install ntp
ntpdate time.nist.gov(同步时钟)
hwclock -w （写入bios）
2.[openstack packages]
安装openstack最新的源：
yum install centos-release-openstack-mitaka
yum install https://rdoproject.org/repos/rdo-release.rpm
yum upgrade (更新源)
yum install python-openstackclient（安装opentack必须的插件）
yum install openstack-selinux（可选则安装这个插件，我直接关闭了selinux，因为不熟，对后续不会有影响）
3.[database]
openstack支持很多的数据库，MySQL or PostgreSQL等
这里我们使用mysql。
yum install mariadb mariadb-server python2-PyMySQL（mariadb是mysql的新版本而已，无需惊讶）
vi /etc/my.cnf
加入：
[mysqld]
bind-address = 192.168.1.48（安装mysql的机器的IP地址）
default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci
character-set-server = utf8
将mysql加入自启动
systemctl enable mariadb.service
启动mysql
systemctl start mariadb.service
设置mysql属性：
直接输入脚本命令：
mysql_secure_installation
按照相关设置即可
注意：注意检查mysqld是否运行。3306端口是否起来
3.[rabbitmq]
安装openstack的消息使者rabbitmq，如果rabbitmq没有运行起来，你的整openstack平台将无法使用。rabbitmq使用5672端口。
yum install rabbitmq-server
systemctl enable rabbitmq-server.service（加入自启动）
systemctl start rabbitmq-server.service（启动）
rabbitmqctl add_user openstack RABBIT_PASS（增加用户openstack，密码自己设置替换掉RABBIT_PASS）
rabbitmqctl set_permissions openstack ".*" ".*" ".*"（给新增的用户授权，没有授权的用户将不能接受和传递消息）
4.[memcached]
memcache为选择安装项目。使用端口11211
yum install memcached python-memcached
systemctl enable memcached.service
systemctl start memcached.service
5.[keystone认证服务]
注意：在之前需要设置好hosts解析，控制节点和计算节点都要做。我的为：
192.168.1.48 control
192.168.1.49 compute
登录数据库创建keystone数据库。
mysql -u root -p
CREATE DATABASE keystone;
设置授权用户和密码：
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
IDENTIFIED BY '密码';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
IDENTIFIED BY '密码';
生成admin_token的随机值：
openssl rand -hex 10
安装keystone
yum install openstack-keystone httpd mod_wsgi
vi /etc/keystone/keystone.conf
使用刚刚生成的随机值替换掉：
admin_token = 随机值（主要为安全，也可以不用替换）
配置数据库连接：
connection = mysql+pymysql://keystone:密码@数据库ip地址/keystone
设置：provider = fernet、
同步keystone数据库：keystone-manage db_sync（一点要查看数据库是否生成表成功）
初始化keys：
keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
配置apache：
vi /etc/httpd/conf/httpd.conf
将ServerName 后面改成主机名，防止启动报错
ServerName control
生成wsgi配置文件：
vi /etc/httpd/conf.d/wsgi-keystone.conf加入：
Listen 5000
Listen 35357
WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
WSGIProcessGroup keystone-public
WSGIScriptAlias / /usr/bin/keystone-wsgi-public
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
Require all granted
WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
WSGIProcessGroup keystone-admin
WSGIScriptAlias / /usr/bin/keystone-wsgi-admin
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
Require all granted
启动httpd：
systemctl enable httpd.service
systemctl start httpd.service
6.[创建keystone的service目录和endpoint]
export OS_TOKEN=上面生成的随机值
export OS_URL=http://control:35357/v3
export OS_IDENTITY_API_VERSION=3
创建keystone的service：
openstack service create --name keystone --description "OpenStack Identity" identity （identity这个认证类型一定不可以错）
创建keystone的endpoint：
openstack endpoint create --region RegionOne \
identity public http://control:5000/v3
openstack endpoint create --region RegionOne \
identity internel http://control:5000/v3
openstack endpoint create --region RegionOne \
identity admin http://control:35357/v3
7.[创建域，用户，租户，角色]
创建默认域default:
openstack domain create --description "Default Domain" default
创建admin的租户：
openstack project create --domain default \
--description "Admin Project" admin
创建admin用户：
openstack user create --domain default \
--password-prompt admin（会提示输入密码为登录dashboard的密码）
创建admin角色：
openstack role create admin
将用户租户角色连接起来：
openstack role add --project admin --user admin admin
创建服务目录：
openstack project create --domain default \
--description "Service Project" service
创建demo信息类似admin：
openstack project create --domain default \
--description "Demo Project" demo
openstack user create --domain default \
--password-prompt demo
openstack role create user
openstack role add --project demo --user demo user
创建完成之后可以使用命令验证：
openstack --os-auth-url http://control:35357/v3 \
--os-project-domain-name default --os-user-domain-name default \
--os-project-name admin --os-username admin token issue
输入密码之后，有正确的输出即为配置正确。
可将环境变量设置为脚本：
vi admin-openrc 加入：
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=xxxx
export OS_AUTH_URL=http://control:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
demo的变量类似即可。
运行使用 . admin-openrc或者使用source admin-openrc
验证输入命令：
openstack token issue
有正确的输出即为配置正确。
8.[glance镜像服务]
建立glance数据
登录mysql
mysql -u root -p
CREATE DATABASE glance;
授权
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
IDENTIFIED BY '密码';
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
IDENTIFIED BY '密码';
运行环境变量：
. admin-openrc
创建glance用户信息：
openstack user create --domain default --password-prompt glance
openstack role add --project service --user glance admin
创建镜像服务目录：
openstack service create --name glance \
--description "OpenStack Image" p_w_picpath
创建镜像endpoint：
penstack endpoint create --region RegionOne \
p_w_picpath public http://control:9292
penstack endpoint create --region RegionOne \
p_w_picpath internal http://control:9292
penstack endpoint create --region RegionOne \
p_w_picpath admin http://control:9292
安装：
yum install openstack-glance
vi /etc/glance/glance-api.conf
配置数据库连接：
connection = mysql+pymysql://glance:密码@数据库ip/glance
找到[keystone_authtoken]（配置认证）
加入：
auth_uri = http://control:5000
auth_url = http://control:35357
memcached_servers = control:11211
auth_type = password
project_domain_name = default
user_domain_name = default

找到[keystone_authtoken]（配置认证）
加入：

同步数据库：
glance-manage db_sync
启动glance：
systemctl enable openstack-glance-api.service \
openstack-glance-registry.service
systemctl start openstack-glance-api.service \
openstack-glance-registry.service
验证：
运行环境变量：
. admin-openrc
下载一个比较小的镜像：
wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img
上传镜像：
openstack p_w_picpath create "cirros" \
--file cirros-0.3.4-x86_64-disk.img \
--disk-format qcow2 --container-format bare \
--public
查看：
openstack p_w_picpath list
有输出 证明glance配置正确
