本文主要介紹了openstack 虛擬機(jī)配置VIP的實(shí)現(xiàn)步驟,包括查詢可用子網(wǎng)、創(chuàng)建VIP地址、綁定VIP到虛擬機(jī)端口等,具有一定的參考價值,感興趣的可以了解一下
1、查詢openstack可使用的子網(wǎng)
[root@test-opctrl ~]# openstack network list +--------------------------------------+---------------+--------------------------------------+ | ID | Name | Subnets | +--------------------------------------+---------------+--------------------------------------+ | 1c9e03f5-5983-49b9-997d-1ba5315da1e2 | net-vlan-1860 | a2204645-c397-42a4-8eb2-52e9ea181d7c | | 2f32187f-e20a-4d67-ae9e-7c6949d03813 | net-vlan-1850 | 8cb50523-d91e-4558-8e89-cd0c84f9fb0f | | 75084d12-883d-4c66-bf27-88cc3adb1d79 | net-vlan-1800 | fdbf0a71-3551-4092-b0be-d1a1f74a50b3 | | 925f9243-2547-482d-a2c3-2a2bcf6e1653 | net-vlan-1870 | 049b9d6f-fc9a-4a76-9598-6bf113dac642 | +--------------------------------------+---------------+--------------------------------------+
2、創(chuàng)建VIP地址
創(chuàng)建port來占用Vip，保證neutron不會將此IP在分配出去，避免后續(xù)虛擬機(jī)自動分配P沖突問題
命令示例：openstack port create --fixed-ip subnet=<subnet_id>,ip-address=<vip_address> <vip-port-name>
subnet_id：openstack集群中子網(wǎng)的Subnets ID
vip_address：需要給虛擬機(jī)配置的VIP
vip-port-name：VIP的端口名稱
3、將VIP綁定至虛擬機(jī)端口
allowed_address_pairs：allowed_address_pairs 是 OpenStack Neutron 中的一個屬性，允許用戶在虛擬機(jī)（VM）接口上配置額外的 IP 地址或 MAC 地址
a）獲取虛擬機(jī)現(xiàn)有端口ID
命令示例：openstack port list --server <server-name> [root@test-opctrl ~]# openstack port list --server test-out-nginx01 +--------------------------------------+------+-------------------+-----------------------------------------------------------------------------+--------+ | ID | Name | MAC Address | Fixed IP Addresses | Status | +--------------------------------------+------+-------------------+-----------------------------------------------------------------------------+--------+ | c7b2115b-6bdd-4608-9229-5d53e4d2bc0b | | fa:16:3e:ff:74:45 | ip_address='10.35.180.1', subnet_id='fdbf0a71-3551-4092-b0be-d1a1f74a50b3' | ACTIVE | +--------------------------------------+------+-------------------+-----------------------------------------------------------------------------+--------+ [root@test-opctrl ~]# openstack port list --server test-out-nginx02 +--------------------------------------+------+-------------------+-----------------------------------------------------------------------------+--------+ | ID | Name | MAC Address | Fixed IP Addresses | Status | +--------------------------------------+------+-------------------+-----------------------------------------------------------------------------+--------+ | a7ae1767-d10e-49bf-a7a8-12ae0ecc8fd1 | | fa:16:3e:16:55:bc | ip_address='10.35.180.2', subnet_id='fdbf0a71-3551-4092-b0be-d1a1f74a50b3' | ACTIVE | +--------------------------------------+------+-------------------+-----------------------------------------------------------------------------+--------+
b）為虛擬機(jī)端口添加allowed_address_pairs配置
使用 openstack port set 命令來配置 allowed_address_pairs
命令示例：openstack port set --allowed-address ip-address=<ip_address>,mac-address=<mac_address> <port_id>
只指定 IP 地址而不指定 MAC 地址。系統(tǒng)將自動允許此 IP 與當(dāng)前端口的 MAC 地址配對
命令示例：openstack port set --allowed-address ip-address=<ip_address> <port_id>
[root@test-opctrl ~]# openstack port set --allowed-address ip-address=10.35.180.100 c7b2115b-6bdd-4608-9229-5d53e4d2bc0b +-----------------------+-----------------------------------------------------------------------------+ | Field | Value | +-----------------------+-----------------------------------------------------------------------------+ | admin_state_up | UP | | allowed_address_pairs | ip_address='10.35.180.100/32', mac_address='fa:16:3e:ff:74:45' | | binding_host_id | test-opnode01 | | binding_profile | | | binding_vif_details | datapath_type='system', ovs_hybrid_plug='True', port_filter='True' | | binding_vif_type | ovs | | binding_vnic_type | normal | | created_at | 2024-08-16T05:58:02Z | | data_plane_status | None | | description | | | device_id | 1ca2a3a4-875e-49ae-a27f-740e7f555526 | | device_owner | compute:nova | | dns_assignment | None | | dns_name | None | | extra_dhcp_opts | | | fixed_ips | ip_address='10.35.180.1', subnet_id='fdbf0a71-3551-4092-b0be-d1a1f74a50b3' | | id | c7b2115b-6bdd-4608-9229-5d53e4d2bc0b | | ip_address | None | | mac_address | fa:16:3e:ff:74:45 | | name | | | network_id | 75084d12-883d-4c66-bf27-88cc3adb1d79 | | option_name | None | | option_value | None | | port_security_enabled | True | | project_id | b892ab684d4c4ee384c6023e68f018e9 | | qos_policy_id | None | | revision_number | 12 | | security_group_ids | 36d985b0-ff44-49a3-a46e-504fe6ae73cd | | status | ACTIVE | | subnet_id | None | | tags | | | trunk_details | None | | updated_at | 2024-08-16T06:21:24Z | +-----------------------+-----------------------------------------------------------------------------+ [root@test-opctrl ~]# openstack port set --allowed-address ip-address=10.35.180.100 a7ae1767-d10e-49bf-a7a8-12ae0ecc8fd1 +-----------------------+-----------------------------------------------------------------------------+ | Field | Value | +-----------------------+-----------------------------------------------------------------------------+ | admin_state_up | UP | | allowed_address_pairs | ip_address='10.35.180.100/32', mac_address='fa:16:3e:16:55:bc' | | binding_host_id | test-opnode02 | | binding_profile | | | binding_vif_details | datapath_type='system', ovs_hybrid_plug='True', port_filter='True' | | binding_vif_type | ovs | | binding_vnic_type | normal | | created_at | 2024-08-16T05:58:15Z | | data_plane_status | None | | description | | | device_id | 3e84febd-dbf4-47cb-8336-dffcd9e59f33 | | device_owner | compute:nova | | dns_assignment | None | | dns_name | None | | extra_dhcp_opts | | | fixed_ips | ip_address='10.35.180.2', subnet_id='fdbf0a71-3551-4092-b0be-d1a1f74a50b3' | | id | a7ae1767-d10e-49bf-a7a8-12ae0ecc8fd1 | | ip_address | None | | mac_address | fa:16:3e:16:55:bc | | name | | | network_id | 75084d12-883d-4c66-bf27-88cc3adb1d79 | | option_name | None | | option_value | None | | port_security_enabled | True | | project_id | b892ab684d4c4ee384c6023e68f018e9 | | qos_policy_id | None | | revision_number | 12 | | security_group_ids | 36d985b0-ff44-49a3-a46e-504fe6ae73cd | | status | ACTIVE | | subnet_id | None | | tags | | | trunk_details | None | | updated_at | 2024-08-16T06:21:47Z | +-----------------------+-----------------------------------------------------------------------------+
4、使用 Keepalived 配置高可用性 VIP
a）安裝keepalived
[root@test-nginx01 ~]# yum -y install keepalived [root@test-nginx02 ~]# yum -y install keepalived
b）配置 Keepalived
編輯每臺虛擬機(jī)上的 Keepalived 配置文件（通常位于 /etc/keepalived/keepalived.conf）
[root@test-nginx01 ~]# cat /etc/keepalived/keepalived.conf
! Configuration File for keepalived
global_defs {
router_id node1
notification_email {
acassen@firewall.loc
failover@firewall.loc
sysadmin@firewall.loc
}
notification_email_from Alexandre.Cassen@firewall.loc
smtp_server 127.0.0.1
smtp_connect_timeout 30
}
#vrrp_script check_nginx {
# script "killall -0 nginx"
# interval 2
# weight 2
#}
vrrp_instance VI_1 {
state BACKUP
interface eth0
virtual_router_id 88
priority 99
advert_int 1
authentication {
auth_type PASS
auth_pass cn1-test-apisix
}
virtual_ipaddress {
10.35.180.100/32 dev eth0 label eth0:1
}
track_script {
check_nginx
}
}
c）啟動 Keepalived
在所有虛擬機(jī)上啟動并使 Keepalived 服務(wù)自動啟動
[root@test-nginx01 ~]# systemctl start keepalived
[root@test-nginx01 ~]# systemctl enable keepalived
[root@test-nginx01 ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether fa:16:3e:ff:74:45 brd ff:ff:ff:ff:ff:ff
inet 10.35.180.1/24 brd 10.35.180.255 scope global eth0
valid_lft forever preferred_lft forever
inet 10.35.180.100/32 scope global eth0:1
