OpenStack虚拟机VIP配置步骤

以下命令使用于 queens版本中

需要配置vip搭建keepalived高可用集群,因此在openstack上的虚拟机如何绑定vip

操作步骤
1、 执行命令neutron net-list查看网络,找到自己需要设置的网络,获取subnet_id和network_id

[root@node151 ~]# neutron net-list
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
+--------------------------------------+----------+----------------------------------+-----------------------------------------------------+
| id                                   | name     | tenant_id                        | subnets                                             |
+--------------------------------------+----------+----------------------------------+-----------------------------------------------------+
| b79db6a0-b74d-48b8-95e8-8260eaf81b70 | provider | 8e4dd46886834371b71984245a143f58 | b8a9d01c-f547-45c3-a0d4-da7ae1494766 192.168.1.0/24 |
+--------------------------------------+----------+----------------------------------+-----------------------------------------------------+

2、创建port来占用ip(192.168.1.170),保证neutron不会将此IP在分配出去,导致IP冲突问题。

neutron port-create --fixed-ip subnet_id=<subnet_id>,ip_address=<vip> <network_id>

注:

替换subnet_id为neutron net-list中查看到的subnet_id
替换vip为需要配置的vip地址
替换network_ID为neutron net-list中查看到的network_id

[root@node151 ~]# neutron port-create --fixed-ip subnet_id=b8a9d01c-f547-45c3-a0d4-da7ae1494766,ip_address=192.168.1.170 b79db6a0-b74d-48b8-95e8-8260eaf81b70
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

3、执行命令neutron port-list查看端口,找到VIP的Port ID以及需要使用VIP的虚拟机的IP对应的Port id 比如两台虚拟机做HA绑定vip,那么需要查看两台虚拟机的port ID和这个vip的port ID**

[root@node151 ~]# neutron port-list|grep 192.168.1.168
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
| cd86f69a-4779-4a46-a0ea-eed76f176237 |      | 8e4dd46886834371b71984245a143f58 | fa:16:3e:e9:76:dc | {"subnet_id": "b8a9d01c-f547-45c3-a0d4-da7ae1494766", "ip_address": "192.168.1.168"} |
[root@node151 ~]# neutron port-list|grep 192.168.1.156
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
| f3bebead-0e94-4909-8a00-ce43a2fc243a |      | 8e4dd46886834371b71984245a143f58 | fa:16:3e:56:46:33 | {"subnet_id": "b8a9d01c-f547-45c3-a0d4-da7ae1494766", "ip_address": "192.168.1.156"} |
[root@node151 ~]# neutron port-list|grep 192.168.1.170
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
| 46b7784a-6bec-4ca4-8c1f-41dc07e40955 |      | 8e4dd46886834371b71984245a143f58 | fa:16:3e:db:8a:6b | {"subnet_id": "b8a9d01c-f547-45c3-a0d4-da7ae1494766", "ip_address": "192.168.1.170"} |

4、取消安全组对应端口的管理

neutron port-update --no-security-groups <Port_id>
neutron port-update --port_security_enabled=false <Port_id>

注:

替换Port_id为之前neutron port-list中找到的Port_id

[root@node151 ~]# neutron port-update --no-security-groups cd86f69a-4779-4a46-a0ea-eed76f176237
update --port_security_enabled=false f3bebead-0e94-4909-8a00-ce43a2fc243a
neutron port-update --no-security-groups 46b7784a-6bec-4ca4-8c1f-41dc07e40955
neutron port-update --port_security_enabled=false 46b7784a-6bec-4ca4-8c1f-41dc07e40955neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

 5、测试vip联通性

在168和156上分别临时增加ip 192.168.1.170 通过ping命令进行测试即可。
