systemctl restart httpd.service memcached.service

##################启动实例###################
创建提供者网络：
neutron net-create --shared --provider:physical_network provider --provider:network_type flat provider
neutron subnet-create --name provider --allocation-pool start=10.0.0.100,end=10.0.0.200 \--dns-nameserver 8.8.8.8 --gateway 10.0.0.1 provider 10.0.0.0/24

创建m1.nano规格的主机
openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano

生成一个键值对：
ssh-keygen -q -N ""
openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
openstack keypair list

openstack security group rule create --proto icmp default
openstack security group rule create --proto tcp --dst-port 22 default

确定实例选项：
openstack flavor list
openstack image list
openstack network list
openstack security group list
