本节开始安装Dashboard，用于对OS进行管理，仅在CT01进行操作

1、安装

apt install openstack-dashboard

2、修改配置
/etc/openstack-dashboard/local_settings.py

OPENSTACK_HOST = "CT01"
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default"
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"

#Dashboard节点
ALLOWED_HOSTS = ['*']

SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

CACHES = {
    ' default' : {
        ' BACKEND' : 'django.core.cache.backends.memcached.MemcachedCache' ,
        ' LOCATION' : 'CT01:11211' ,
    }
}

OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST

OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True

OPENSTACK_API_VERSIONS = {
"identity": 3,
"image": 2,

3、重启服务

service apache2 reload

4、浏览器打开网页
http://CT01/horizon
可以用admin或user01用户进行访问

PS：出现500错误

#查看apache日志发现，是下面文件权限设置有问题，改一下就好了
sudo chown www-data:www-data /var/lib/openstack-dashboard/secret_key

5、用下面的步骤创建实例

2、主机资源规划
一共使用了五台虚拟机，一台主控，一台做云计算（需打开虚拟化支持），一台做云存储，两台做对象存储
每台虚拟机都有两块网卡，一块为HostOnly用于内部通讯，一块为NAT，用于软件安装

3、IP及Hostname设置
以主控为例，每一个节点都要设置
/etc/hostname

CT01

/etc/hosts

10.0.3.10   CT01
10.0.3.11   PC01
10.0.3.12   BS01
10.0.3.13   OS01
10.0.3.14   OS02

/etc/network/interfaces

#hostonly
auto enp0s3
iface enp0s3 inet static
address 10.0.3.10
netmask 255.255.255.0

#nat
auto enp0s8
iface enp0s8 inet static
address 172.16.172.70
netmask 255.255.0.0
dns-nameserver 8.8.8.8
dns-nameserver 114.114.114.114

4、系统升级
每一个节点都要执行

apt install software-properties-common
add-apt-repository cloud-archive:ocata
apt update
apt dist-upgrade

5、时间同步
5.1、主控节点

#安装chrony
apt install chrony

#编辑配置文件，修改下面几行
vi /etc/chrony/chrony.conf
server 52.187.51.163 iburst
allow 10.0.3.0/24
allow 172.16.172.0/24

#重启服务，并同步时间
service chrony restart
chronyc sources

5.2、其他节点

#安装chrony
apt install chrony

#编辑配置文件，修改下面几行
vi /etc/chrony/chrony.conf
server CT01 iburst

#重启服务，并同步时间
service chrony restart
chronyc sources

6、安装python-openstackclient
每一个节点都要执行

apt install python-openstackclient
