1、创建self-service网络
（1）加载系统变量：
[root@ren3 ~]# source openrc
（2）创建网络：
[root@ren3 ~]# openstack network list [root@ren3 ~]# openstack network create my_network +---------------------------+--------------------------------------+ | Field | Value | +---------------------------+--------------------------------------+ | admin_state_up | UP | | availability_zone_hints | | | availability_zones | | | created_at | 2019-10-17T07:33:52Z | | description | | | dns_domain | None | | id | 062d2b07-339e-4d54-aaca-6b9169d17f6c | | ipv4_address_scope | None | | ipv6_address_scope | None | | is_default | None | | mtu | 1450 | | name | my_network | | port_security_enabled | True | | project_id | 640da7a471524d35a3efca2692b9555a | | provider:network_type | vxlan | | provider:physical_network | None | | provider:segmentation_id | 85 | | qos_policy_id | None | | revision_number | 3 | | router:external | Internal | | segments | None | | shared | False | | status | ACTIVE | | subnets | | | updated_at | 2019-10-17T07:33:52Z | +---------------------------+--------------------------------------+ [root@ren3 ~]# openstack network list +--------------------------------------+------------+---------+ | ID | Name | Subnets | +--------------------------------------+------------+---------+ | 062d2b07-339e-4d54-aaca-6b9169d17f6c | my_network | | +--------------------------------------+------------+---------+
（3）在网络上创建子网
[root@ren3 ~]# openstack subnet create --network my_network --dns-nameserver 8.8.8.8 --gateway 12.12.12.1 --subnet-range 12.12.12.0/24 --allocation-pool start=12.12.12.10,end=12.12.12.20 my_network.subnet +-------------------+--------------------------------------+ | Field | Value | +-------------------+--------------------------------------+ | allocation_pools | 12.12.12.10-12.12.12.20 | | cidr | 12.12.12.0/24 | | created_at | 2019-10-17T07:40:38Z | | description | | | dns_nameservers | 8.8.8.8 | | enable_dhcp | True | | gateway_ip | 12.12.12.1 | | host_routes | | | id | 54175b19-fada-4875-b00c-20e556433bdf | | ip_version | 4 | | ipv6_address_mode | None | | ipv6_ra_mode | None | | name | my_network.subnet | | network_id | 062d2b07-339e-4d54-aaca-6b9169d17f6c | | project_id | 640da7a471524d35a3efca2692b9555a | | revision_number | 2 | | segment_id | None | | service_types | | | subnetpool_id | None | | updated_at | 2019-10-17T07:40:38Z | +-------------------+--------------------------------------+ [root@ren3 ~]# openstack subnet list +-----------------+-----------------+------------------+---------------+ | ID | Name | Network | Subnet | +-----------------+-----------------+------------------+---------------+ | 54175b19-fada-4 | my_network.subn | 062d2b07-339e- | 12.12.12.0/24 | | 875-b00c- | et | 4d54-aaca- | | | 20e556433bdf | | 6b9169d17f6c | | +-----------------+-----------------+------------------+---------------+
2、创建一个路由器
（1）创建路由
[root@ren3 ~]# openstack router list [root@ren3 ~]# openstack router create router +-------------------------+--------------------------------------+ | Field | Value | +-------------------------+--------------------------------------+ | admin_state_up | UP | | availability_zone_hints | | | availability_zones | | | created_at | 2019-10-17T07:41:55Z | | description | | | distributed | False | | external_gateway_info | None | | flavor_id | None | | ha | False | | id | 84d406c2-3923-4a52-9368-9e310a40edb9 | | name | router | | project_id | 640da7a471524d35a3efca2692b9555a | | revision_number | None | | routes | | | status | ACTIVE | | updated_at | 2019-10-17T07:41:55Z | +-------------------------+--------------------------------------+ [root@ren3 ~]# openstack router list +-----------+--------+--------+-------+-------------+-------+------------+ | ID | Name | Status | State | Distributed | HA | Project | +-----------+--------+--------+-------+-------------+-------+------------+ | 84d406c2- | router | ACTIVE | UP | False | False | 640da7a471 | | 3923-4a52 | | | | | | 524d35a3ef | | -9368-9e3 | | | | | | ca2692b955 | | 10a40edb9 | | | | | | 5a | +-----------+--------+--------+-------+-------------+-------+------------+
（2）在路由器上添加自助网络子网作为接口：
[root@ren3 ~]# neutron router-interface-add router my_network neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead. Unable to find subnet with name or id 'my_network' [root@ren3 ~]# neutron router-interface-add router my_network.subnet neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead. Added interface 9c86abfa-c5d5-44c7-9aea-bd254c64781c to router router.
（3）在路由器上设置网关：（先创建一个外网）

通过实例控制台登录实例虚拟机中，测试网关是否能ping通：
在图像化界面创建实例有两种方式：
（1）不创建新卷（虚机的disk文件保存在计算节点的/var/lib/nova/instances/INSTANCE_ID/）
[root@ren4 instances]# pwd /var/lib/nova/instances [root@ren4 instances]# ls ae4ac65d-8708-4589-8b1c-24b67a533495 compute_nodes _base locks ce360d28-28e2-4344-a9f2-4dd228eadd4a [root@ren4 instances]# cd ce360d28-28e2-4344-a9f2-4dd228eadd4a/ [root@ren4 ce360d28-28e2-4344-a9f2-4dd228eadd4a]# ls console.log disk disk.info [root@ren4 ce360d28-28e2-4344-a9f2-4dd228eadd4a]# cd ../ae4ac65d-8708-4589-8b1c-24b67a533495/ [root@ren4 ae4ac65d-8708-4589-8b1c-24b67a533495]# ls console.log
（2）创建新卷（虚机的disk文件保存在存储节点的/dev/cinder-volumes/）

2、使用虚拟控制台访问实例
[root@ren3 ~]# openstack console url show lamp_instance1 +-------+--------------------------------------------------------------+ | Field | Value | +-------+--------------------------------------------------------------+ | type | novnc | | url | http://192.168.11.3:6080/vnc_auto.html?token=e2b3be5b-ae4d- | | | 48e8-be86-400c1bb467ef | +-------+--------------------------------------------------------------+
3、远程访问实例（创建浮点ip并添加至实例1）
[root@ren3 ~]# openstack floating ip create external_network +---------------------+--------------------------------------+ | Field | Value | +---------------------+--------------------------------------+ | created_at | 2019-10-17T11:44:40Z | | description | | | fixed_ip_address | None | | floating_ip_address | 192.168.11.109 | | floating_network_id | d97c8576-1990-4920-adea-98589cc816ab | | id | 4407b6d6-ae73-46b6-8aec-8fdf65be5035 | | name | None | | port_id | None | | project_id | 640da7a471524d35a3efca2692b9555a | | revision_number | 1 | | router_id | None | | status | DOWN | | updated_at | 2019-10-17T11:44:40Z | +---------------------+--------------------------------------+ [root@ren3 ~]# openstack server add floating ip lamp_instance1 192.168.11.109
查看是否添加了浮点ip：
[root@ren3 ~]# openstack server list +---------------+---------------+--------+----------------+------------+ | ID | Name | Status | Networks | Image Name | +---------------+---------------+--------+----------------+------------+ | ce360d28-28e2 | lamp_instance | ACTIVE | my_network=12. | cirros | | -4344-a9f2-4d | 1 | | 12.12.14, | | | d228eadd4a | | | 192.168.11.109 | | +---------------+---------------+--------+----------------+------------+
测试浮点ip是否通：
[root@ren3 ~]# ping -c 4 192.168.11.109 PING 192.168.11.109 (192.168.11.109) 56(84) bytes of data. 64 bytes from 192.168.11.109: icmp_seq=1 ttl=63 time=6.52 ms 64 bytes from 192.168.11.109: icmp_seq=2 ttl=63 time=1.65 ms 64 bytes from 192.168.11.109: icmp_seq=3 ttl=63 time=2.70 ms 64 bytes from 192.168.11.109: icmp_seq=4 ttl=63 time=2.50 ms --- 192.168.11.109 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3008ms rtt min/avg/max/mdev = 1.656/3.348/6.529/1.878 ms
通过ssh远程连接实例1：
[root@ren3 ~]# ssh cirros@192.168.11.109 The authenticity of host '192.168.11.109 (192.168.11.109)' can't be established. RSA key fingerprint is SHA256:JK9leF3dSxiLvAdDFStoiEuJ9yQ5A0lAoHx1O4rznoM.

如果创建了多台虚机，可使用一台有浮动ip的虚机作为其他虚机的跳板机，来远程控制（虚机之间可以互相通信，就不用再给其它虚机添加浮动ip，可以节省外网ip资源）
[root@ren3 ~]# ssh cirros@192.168.11.109 $ $ ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc pfifo_fast qlen 1000 link/ether fa:16:3e:34:6a:2d brd ff:ff:ff:ff:ff:ff inet 12.12.12.14/24 brd 12.12.12.255 scope global eth0 inet6 fe80::f816:3eff:fe34:6a2d/64 scope link valid_lft forever preferred_lft forever $ $ ping 12.12.12.17 PING 12.12.12.17 (12.12.12.17): 56 data bytes 64 bytes from 12.12.12.17: seq=0 ttl=64 time=8.151 ms 64 bytes from 12.12.12.17: seq=1 ttl=64 time=3.266 ms ^C --- 12.12.12.17 ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max = 3.266/5.708/8.151 ms $ $ ssh cirros@12.12.12.17 Host '12.12.12.17' is not in the trusted hosts file.

六、创建块存储
1、创建卷
[root@ren3 ~]# . openrc [root@ren3 ~]# openstack volume list [root@ren3 ~]# openstack volume create --size 1 volume1 +---------------------+--------------------------------------+ | Field | Value | +---------------------+--------------------------------------+ | attachments | [] | | availability_zone | nova | | bootable | false | | consistencygroup_id | None | | created_at | 2019-10-18T06:42:28.402838 | | description | None | | encrypted | False | | id | 644b94e9-416b-4c2c-9606-06dba5f474cc | | migration_status | None | | multiattach | False | | name | volume1 | | properties | | | replication_status | None | | size | 1 | | snapshot_id | None | | source_volid | None | | status | creating | | type | None | | updated_at | None | | user_id | 372fccfd264c4edfb600af3f56052ec7 | +---------------------+--------------------------------------+ [root@ren3 ~]# openstack volume list +------------------+--------------+-----------+------+-------------+ | ID | Display Name | Status | Size | Attached to | +------------------+--------------+-----------+------+-------------+ | 644b94e9-416b-4c | volume1 | available | 1 | | | 2c-9606-06dba5f4 | | | | | | 74cc | | | | | +------------------+--------------+-----------+------+-------------+
2、将该卷添加到一个实例
[root@ren3 ~]# openstack server list +---------------+---------------+--------+----------------+------------+ | ID | Name | Status | Networks | Image Name | +---------------+---------------+--------+----------------+------------+ | ce360d28-28e2 | lamp_instance | ACTIVE | my_network=12. | cirros | | -4344-a9f2-4d | 1 | | 12.12.14, | | | d228eadd4a | | | 192.168.11.109 | | +---------------+---------------+--------+----------------+------------+ [root@ren3 ~]# openstack server add volume lamp_instance1 volume1 [root@ren3 ~]# openstack volume list +------------------+--------------+-----------+------+-------------+ | ID | Display Name | Status | Size | Attached to | +------------------+--------------+-----------+------+-------------+ | 644b94e9-416b-4c | volume1 | attaching | 1 | | | 2c-9606-06dba5f4 | | | | | | 74cc | | | | | +------------------+--------------+-----------+------+-------------+
