1、创建网络和子网
[[email protected] ~]# source admin-openrc.sh [[email protected] ~]# neutron net-create flat --shared --provider:physical_network physnet1 --provider:network_type flat Created a new network: +---------------------------+--------------------------------------+ | Field | Value | +---------------------------+--------------------------------------+ | admin_state_up | True | | id | 61b74dc3-e39a-4a35-ad7a-64c71e2740d7 | | mtu | 0 | | name | flat | | port_security_enabled | True | | provider:network_type | flat | | provider:physical_network | physnet1 | | provider:segmentation_id | | | router:external | False | | shared | True | | status | ACTIVE | | subnets | | | tenant_id | 8a3b7f9f1b2c4f7eaf7780d268e672d1 | +---------------------------+--------------------------------------+ [[email protected] ~]# [[email protected] ~]# neutron subnet-create flat 172.16.80.0/24 --name flat-subnet --allocation-pool start=172.16.80.180,end=172.16.80.230 --dns-nameserver 114.114.114.114 --gateway 172.16.80.2 Created a new subnet: +-------------------+----------------------------------------------------+ | Field | Value | +-------------------+----------------------------------------------------+ | allocation_pools | {"start": "172.16.80.180", "end": "172.16.80.230"} | | cidr | 172.16.80.0/24 | | dns_nameservers | 114.114.114.114 | | enable_dhcp | True | | gateway_ip | 172.16.80.2 | | host_routes | | | id | ec1e5cb6-e1c2-462c-865e-85383a97a434 | | ip_version | 4 | | ipv6_address_mode | | | ipv6_ra_mode | | | name | flat-subnet | | network_id | 61b74dc3-e39a-4a35-ad7a-64c71e2740d7 | | subnetpool_id | | | tenant_id | 8a3b7f9f1b2c4f7eaf7780d268e672d1 | +-------------------+----------------------------------------------------+ 查看创建的网络 [[email protected] ~]# neutron net-list +--------------------------------------+------+-----------------------------------------------------+ | id | name | subnets | +--------------------------------------+------+-----------------------------------------------------+ | 61b74dc3-e39a-4a35-ad7a-64c71e2740d7 | flat | ec1e5cb6-e1c2-462c-865e-85383a97a434 172.16.80.0/24 | +--------------------------------------+------+-----------------------------------------------------+
2、创建公钥和私钥，添加到openstack中
[[email protected] ~]# source demo-openrc.sh [[email protected] ~]# ssh-keygen -q -N "" Enter file in which to save the key (/root/.ssh/id_rsa): /root/.ssh/id_rsa already exists. Overwrite (y/n)? y [[email protected] ~]# nova keypair-add --pub-key .ssh/id_rsa.pub mykey [[email protected] ~]# nova keypair-list +-------+-------------------------------------------------+ | Name | Fingerprint | +-------+-------------------------------------------------+ | mykey | 1c:e7:78:fe:de:e1:0d:b4:1f:55:b9:a1:01:4b:21:52 | +-------+-------------------------------------------------+
3、创建一个安全组放行icmp和ssh
[[email protected] ~]# nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0 +-------------+-----------+---------+-----------+--------------+ | IP Protocol | From Port | To Port | IP Range | Source Group | +-------------+-----------+---------+-----------+--------------+ | icmp | -1 | -1 | 0.0.0.0/0 | | +-------------+-----------+---------+-----------+--------------+ [[email protected] ~]# nova secgroup-add-rule default tcp 22 22 0.0.0.0/0 +-------------+-----------+---------+-----------+--------------+ | IP Protocol | From Port | To Port | IP Range | Source Group | +-------------+-----------+---------+-----------+--------------+ | tcp | 22 | 22 | 0.0.0.0/0 | | +-------------+-----------+---------+-----------+--------------+ [[email protected] ~]# nova flavor-list +----+-----------+-----------+------+-----------+------+-------+-------------+-----------+ | ID | Name | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public | +----+-----------+-----------+------+-----------+------+-------+-------------+-----------+ | 1 | m1.tiny | 512 | 1 | 0 | | 1 | 1.0 | True | | 2 | m1.small | 2048 | 20 | 0 | | 1 | 1.0 | True | | 3 | m1.medium | 4096 | 40 | 0 | | 2 | 1.0 | True | | 4 | m1.large | 8192 | 80 | 0 | | 4 | 1.0 | True | | 5 | m1.xlarge | 16384 | 160 | 0 | | 8 | 1.0 | True | +----+-----------+-----------+------+-----------+------+-------+-------------+-----------+ [[email protected] ~]# nova image-list +--------------------------------------+--------+--------+--------+ | ID | Name | Status | Server | +--------------------------------------+--------+--------+--------+ | 6772deca-7b31-4f97-affa-668518b22972 | cirros | ACTIVE | | +--------------------------------------+--------+--------+--------+ [[email protected] ~]# neutron net-list +--------------------------------------+------+-----------------------------------------------------+ | id | name | subnets | +--------------------------------------+------+-----------------------------------------------------+ | 61b74dc3-e39a-4a35-ad7a-64c71e2740d7 | flat | ec1e5cb6-e1c2-462c-865e-85383a97a434 172.16.80.0/24 | +--------------------------------------+------+-----------------------------------------------------+ [[email protected] ~]# nova secgroup-list +--------------------------------------+---------+------------------------+ | Id | Name | Description | +--------------------------------------+---------+------------------------+ | 4751243a-79a7-4629-b12e-e5f7030d1c85 | default | Default security group | +--------------------------------------+---------+------------------------+
4、创建虚拟机
[[email protected] ~]# nova boot --flavor m1.tiny --image cirros --nic net-id=61b74dc3-e39a-4a35-ad7a-64c71e2740d7 --security-group default --key-name mykey martin +--------------------------------------+-----------------------------------------------+ | Property | Value | +--------------------------------------+-----------------------------------------------+ | OS-DCF:diskConfig | MANUAL | | OS-EXT-AZ:availability_zone | | | OS-EXT-STS:power_state | 0 | | OS-EXT-STS:task_state | scheduling | | OS-EXT-STS:vm_state | building | | OS-SRV-USG:launched_at | - | | OS-SRV-USG:terminated_at | - | | accessIPv4 | | | accessIPv6 | | | adminPass | XxwtiCC7LWQr | | config_drive | | | created | 2016-11-02T14:20:44Z | | flavor | m1.tiny (1) | | hostId | | | id | a1d9a40f-ca6a-4e69-854f-671a16f3374c | | image | cirros (6772deca-7b31-4f97-affa-668518b22972) | | key_name | mykey | | metadata | {} | | name | martin | | os-extended-volumes:volumes_attached | [] | | progress | 0 | | security_groups | default | | status | BUILD | | tenant_id | 3653ec22551f472b94e9438bcd9097bf | | updated | 2016-11-02T14:20:45Z | | user_id | da1ed7fb5f494091a633afd6da29f900 | +--------------------------------------+-----------------------------------------------+
5、安装dashboard
[[email protected] ~]# yum install openstack-dashboard -y [[email protected] openstack-dashboard]#vim /etc/openstack-dashboard/local_settings ALLOWED_HOSTS = [‘*‘, ‘localhost‘] OPENSTACK_HOST = "172.16.80.130" OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user" CACHES = { ‘default‘: { ‘BACKEND‘: ‘django.core.cache.backends.memcached.Memcac hedCache‘, ‘LOCATION‘: ‘172.16.80.130:11211‘, } } TIME_ZONE = "Asia/ShangHai" [[email protected] openstack-dashboard]# systemctl restart httpd
6、创建云主机
中途有报错

解决办法，修改计算节点的配置文件
vif_plugging_is_fatal=false
vif_plugging_timeout=0
[[email protected] nova]# systemctl restart libvirtd openstack-nova-compute
7、登录测试
[[email protected] nova]# ssh [email protected] The authenticity of host ‘172.16.80.184 (172.16.80.184)‘ can‘t be established. RSA key fingerprint is b5:e8:9c:7c:15:22:26:09:6e:f4:aa:e0:61:79:25:f7. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added ‘172.16.80.184‘ (RSA) to the list of known hosts.
