没有流量通过 openstack 浮动 IP 和起搏器/corosync 到达

772

我正在遵循https://fuga.cloud/academy/tutorials/ha-vip-with-corosync-on-openstack/中的步骤。

我错过了为什么进入外部浮动 IP 的流量没有正确到达绑定到相关网络端口的机器上的原因。

下面的代码将创建：

3 台具有外部 ips 的 LB 机器（curl port80 显示 nginx 响应）
3 个额外的网络端口，用于内部故障转移 IP 10.0.0.20{1,2,3}
3 个额外的外部 IP 绑定到这些网络端口（curl port80 超时）

在内部 ping/curl 10.0.0.20{1,2,3} ips 工作得很好。但是，如果我尝试通过外部 IP 访问它 - 超时。此外：tcpdump 显示没有流量到达机器上。

负载均衡器网络端口和机器创建：

vars：子网 10.0.0.0/24，vip = [201,202,203]，lb_count = 3 个安全组：全局允许端口 80

resource "opentelekomcloud_networking_port_v2" "port_lb" {
  depends_on     = ["opentelekomcloud_networking_router_interface_v2.router_interface_1"]
  count          = "${var.lb_count}"

  network_id     = "${opentelekomcloud_networking_network_v2.network_lb.id}"
  admin_state_up = "true"

  security_group_ids = ["${opentelekomcloud_compute_secgroup_v2.secgroup_lb.id}"]

  # all 3 IPs need to be allowed on each port. They are rotating on failover.
  allowed_address_pairs {      
    ip_address = "${cidrhost(var.lb_subnet, element(var.vips, 0))}"
  }
  allowed_address_pairs {      
    ip_address = "${cidrhost(var.lb_subnet, element(var.vips, 1))}"
  }
  allowed_address_pairs {      
    ip_address = "${cidrhost(var.lb_subnet, element(var.vips, 2))}"
  } 
}   

resource "opentelekomcloud_networking_floatingip_v2" "ip_lb" {

  depends_on        = ["opentelekomcloud_networking_floatingip_v2.ip_lb", "opentelekomcloud_networking_port_v2.port_lb"]

  count             = "${var.lb_count}"             
  name              = "${var.environment}-${var.name}-lb-${format("%02d", count.index+1)}"

  block_device {               
    uuid                  = "${var.lb_image_id}"          
    source_type           = "image" 
    volume_size           = "${var.lb_disk_size_gb}"      
    boot_index            = 0  
    destination_type      = "volume"
    delete_on_termination = true
  }

  network {
    port = "${element(opentelekomcloud_networking_port_v2.port_lb.*.id, count.index)}"
  }
}

网络端口 - 10.0.0.20{1,2,3} 的虚拟 ip

resource "opentelekomcloud_networking_port_v2" "port_vip" {
  count          = "${var.lb_count}"
  name           = "${var.environment}-${var.name}-port-vip-${format("%02d", count.index+1)}"
  network_id     = "${opentelekomcloud_networking_network_v2.network_lb.id}"
  admin_state_up = "true"      

  security_group_ids = ["${opentelekomcloud_compute_secgroup_v2.secgroup_lb.id}"]

  fixed_ip = [ { 
    subnet_id = "${opentelekomcloud_networking_subnet_v2.subnet_lb.id}"
    ip_address = "${cidrhost(var.lb_subnet, element(var.vips, count.index))}"
   }]
} 

resource "opentelekomcloud_networking_floatingip_v2" "vip_ip" {
  count    = "${var.lb_count}" 
  pool     = "admin_external_net" 
  port_id  = "${element(opentelekomcloud_networking_port_v2.port_vip.*.id, count.index)}"
}

端口的 Openstack 输出：

丢失的部分是：

device_owner 必须在 port_vip 上设置：neutron:VIP_PORT
port_vip 资源还必须具有 allowed_address_pairs 块（每个负载均衡器 3 个；我将 fixed_ips 添加到上述 port_lb 资源，我将它们列入 port_vip 的白名单）

希望这可以帮助某人
