##openstack服务安装通用步骤
a:mysql中创库授权
b:在keystone创建系统账号,并关联角色
c:在keystone上创建服务名称,注册api
d:安装相关软件包
e:修改配置文件
f:同步数据(创表)
g:启动服务
h:验证

c:启动

systemctl restart openstack-nova-compute.service
systemctl enable neutron-linuxbridge-agent.service
systemctl start neutron-linuxbridge-agent.service

d:控制节点验证

neutron agent-list

##在计算节点上安装dashboard服务
a:安装

yum install openstack-dashboard -y

b:配置
#上传local_settings文件

cat local_settings >/etc/openstack-dashboard/local_settings

c:启动

systemctl enable httpd.service
systemctl start httpd.service

#控制节点创建网络

neutron net-create --shared --provider:physical_network provider --provider:network_type flat WAN
neutron subnet-create --name subnet-wan --allocation-pool 
start=10.0.0.100,end=10.0.0.200 --dns-nameserver 223.5.5.5 
--gateway 10.0.0.254 WAN 10.0.0.0/24

#控制节点创建硬件配置方案

openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano

如果出现如下这种错误

在计算节点编辑/etc/nova/nova.conf 文件中的libvirt
