1：quota相关配置：
1.1：查看当前配额：
[root@node1 ~]# neutron quota-show admin
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
+---------------------+-------+
| Field | Value |
+---------------------+-------+
| floatingip | 50 |
| network | 100 |
| port | 500 |
| rbac_policy | 10 |
| router | 10 |
| security_group | 10 |
| security_group_rule | 100 |
| subnet | 100 |
| subnetpool | -1 |

1.2：web端修改项目配额：
1.2.1：查看openstack配置文件(/etc/httpd/conf.d/openstack-dashboard.conf)是否开启配额限制：
1.2.2：修改web端配额：
1.3：修改/etc/neutron/neutron.conf：
1.3.1：控制端：
[quotas]
quota_network = 200
quota_subnet = 200
quota_port = 5000
quota_driver = neutron.db.quota.driver.DbQuotaDriver
quota_router = 100
quota_floatingip = 1000
quota_security_group = 100
quota_security_group_rule = 1000
#重启neutron服务
[root@node1 ~]# systemctl restart openstack-nova-api.service neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
15.1.3.2：计算节点：
[quotas]
quota_network = 200
quota_subnet = 200
quota_port = 5000
quota_driver = neutron.db.quota.driver.DbQuotaDriver
quota_router = 100
quota_floatingip = 50
quota_security_group = 100
quota_security_group_rule = 1000
#重启neutron服务
[root@node3 ~]# systemctl restart neutron-linuxbridge-agent
1.4：验证当前配额：
2：修改用户配额
2.1：单独调整单个用户的配额
2.2：修改默认配额
查看当前默认值
[root@node1 ~]# nova quota-defaults
