compute1 10.0.0.31
常用服务端口
mariadb：3306
memcached:11211
消息队列：5672和25672
时间同步：123和323
keystone：5000和35357

yum源配置
cd /etc/yum.repos.d/
ls
mkdir qiangge
mv *.repo qiangge
ls
echo '
name=openstack
baseurl=http://192.168.21.92/repo/
gpgcheck=0
name=local
baseurl=http://192.168.21.92/local/
gpgcheck=0' >openstack.repo
yum clean all
yum makecache

确定您的计算节点是否支持虚拟机的硬件加速
egrep -c '(vmx|svm)' /proc/cpuinfo
如果这个命令返回了 one or greater 的值，那么你的计算节点支持硬件加速且不需要额外的配置。
如果这个命令返回了 zero 值，那么你的计算节点不支持硬件加速。你必须配置 libvirt 来使用 QEMU 去代替 KVM
在 /etc/nova/nova.conf 文件的 区域做出如下的编辑：
...
virt_type = qemu

网络服务初始化脚本需要一个超链接/etc/neutron/plugin.ini指向ML2插件配置文件/etc/neutron/plugins/ml2/ml2_conf.ini。如果超链接不存在，使用下面的命令创建它
ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
同步数据库
su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron

Dashboard
contorller
安装软件包
yum install openstack-dashboard
编辑/etc/openstack-dashboard/local_settings文件
在 controller 节点上配置仪表盘以使用 OpenStack 服务：
OPENSTACK_HOST = "controller"
允许所有主机访问仪表板：
ALLOWED_HOSTS = ['*', ]
配置 memcached 会话存储服务：
SESSION_ENGINE = 'django.contrib.sessions.backends.cache'
CACHES = {
'default': {
'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
'LOCATION': 'controller:11211',
}
}
启用第3版认证API:
OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST
启用对域的支持
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True
配置API版本:
OPENSTACKAPIVERSIONS = { "identity": 3, "image": 2, "volume": 2, } 通过仪表盘创建用户时的默认域配置为 default :
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "default"
通过仪表盘创建的用户默认角色配置为 user ：
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"
如果您选择网络参数1，禁用支持3层网络服务：
OPENSTACK_NEUTRON_NETWORK = {
...
'enable_router': False,
'enable_quotas': False,
'enable_distributed_router': False,
'enable_ha_router': False,
'enable_lb': False,
'enable_firewall': False,
'enable_vpn': False,
'enable_fip_topology_check': False,
}
可以选择性地配置时区：
TIME_ZONE = "Aisa/Shanghai"
重启web服务器以及会话存储服务
systemctl restart httpd.service memcached.service
验证操作
在浏览器中输入http://controller/dashboard访问仪表盘。
验证使用admin或者demo用户凭证和default域凭证。
启动实例
创建提供者网络
在控制节点上，加载 admin 凭证来获取管理员能执行的命令访问权限
. admin-openrc
创建网络
neutron net-create --shared --provider:physical_network provider --provider:network_type flat provider
创建子网
neutron subnet-create --name provider --allocation-pool start=10.0.0.101,end=10.0.0.250--dns-nameserver 223.5.5.5 --gateway 10.0.0.254 provider 10.0.0.0/24
检查验证
neutron net-list
neutron subnet-list
创建m1.nano规格的主机
使用m1.nano规格的主机来加载CirrOS镜像
openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano
openstack flavor list
生成和添加秘钥对：
ssh-keygen -q -N ""
openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
验证公钥的添加
openstack keypair list
添加规则到 default 安全组
允许 ICMP (ping)：
openstack security group rule create --proto icmp default
允许安全 shell (SSH) 的访问：
openstack security group rule create --proto tcp --dst-port 22 default
