username = placement
password = openstack

同步数据库

# su -s /bin/sh -c "placement-manage db sync" placement

添加配置/etc/httpd/conf.d/00-placement-api.conf （如果有则跳过）

<Directory /usr/bin>
    <IfVersion >= 2.4>
        Require all granted
    </IfVersion>
    <IfVersion < 2.4>
        Order allow,deny
        Allow from all
    </IfVersion>
</Directory>

服务启动

# systemctl restart httpd

10. Dashboard图形化展示

安装软件包

# yum install -y openstack-dashboard

编辑配置文件/etc/openstack-dashboard/local_settings

ALLOWED_HOSTS = ["*",]

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

CACHES = {
    'default': {
         'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
         'LOCATION': 'controller:11211',
    }
}
OPENSTACK_HOST = "controller"
OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"

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

11. 云环境初始化

镜像初始化

# yum install -y wget
# wget https://download.cirros-cloud.net/0.3.6/cirros-0.3.6-x86_64-disk.img
# . /root/keystonerc_admin
# openstack image create --disk-format qcow2 --container-format bare --public --file cirros-0.3.6-x86_64-disk.img cirros-0.3.6

网络初始化

# openstack network create Public --provider-network-type vlan --provider-physical-network extnet  --provider-segment 10 --external
# openstack subnet create Subnet-Public --no-dhcp --network Public --subnet-range 172.24.4.0/24

# openstack network create vlannet1 --provider-network-type vlan  --provider-physical-network vlannet
# openstack subnet create subnet-vlannet1 --network vlannet1 --subnet-range 10.1.1.0/24

# openstack router create AdminRouter

# openstack router set --external-gateway Public AdminRouter
# openstack router add subnet AdminRouter subnet-vlannet1

Flavor初始化

# openstack flavor create --id 0 --vcpus 1  --ram 256 --disk 1 --public m1.1c.256m.1G

默认安全组规则调整

# openstack security group rule create --protocol any  --ingress --ethertype IPv4  681f291a-507f-49bc-8673-4c1239c3b7fb

Nova创建云主机

# openstack server create --image cirros-0.3.6 --flavor 0  --network vlannet1 VM1

浮动IP绑定

# openstack floating ip create Public --floating-ip-address 172.24.4.217 \
  --fixed-ip-address 10.1.1.217 --port 70567ad4-c49c-44c7-9ee7-63dad9e17e6b
