neutron命令行创建ELB

Jneee 于 2020-08-09 发布

创建的LB如果不指定tenant_id console上面是看不到的，以下命令大部分都能指定租户ID：--tenant_id 9fbf9f44b8e44cd19933ac1fd9b30f49，这个ID是console上面的项目ID，两种查看方法：

  1. console -> 个人设置 -> 项目ID -> ID
  2. cps控制节点：neutron lbaas-loadbalancer-show LB_name

1. 创建VPC和子网

  1. neutron net-create net-liu

  2. neutron subnet-create –name subnet-liu net-liu 10.0.0.0/24 neutron subnet-create –ip-version 6 net-zhong fd00::/112 –name subnet-ipv6

  3. export token=openstack token issue | grep id | grep -v project_id | grep -v user_id | awk '{print $4}' curl -k -X POST https://network.az1.dc1.domainname.com/v2.0/routers -H “User-Agent: python-neutronclient” -H “Content-Type: application/json” -H “Accept: application/json” -H “X-Auth-Token: $token” -d ‘{“router”:{“name”:”router_name”,”external_gateway_info”:{“network_id”:”294ebbf9-29d9-4248-8bc2-15efad6c172b”,”enable_snat”:false},”distributed”:true,”admin_state_up”:true}}’ 其中network_id 一般填写 dummy_external_network 的ID
  4. neutron router-interface-add router_name subnet_name

2. 创建虚拟机镜像和规格

  1. glance image-create –name=”euler” –visibility public –disk-format=qcow2 –container-format=bare –file /opt/HUAWEI/image/kvm_euler_basetemplate-1.25.5.qcow2

  2. nova flavor-create ovs 21 2048 20 2 nova flavor-key 22 set hw:mem_page_size=1048576

  3. nova boot –flavor ovs –nic net-id=net_id –image euler vm_name
  4. nova boot –image euler –flavor ovs –nic port-id=6a3dc5b3-1843-47da-ba35-9720bf6a589a ljn02

3. 放通安全组

默认安全组已放通出方向流量，只用加个入方向。安全组id用 neutron port-show 查看 ![](http://3ms.huawei.com/hi/index.php?app=home&mod=Attach&act=showTempImage&filename=20200813032142145001m378.png)

  1. neutron security-group-rule-create –direction ingress –remote-ip-prefix 0.0.0.0/0 net_id
  2. neutron security-group-rule-create –direction ingress –remote-ip-prefix ::/0 –ethertype ipv6 net_id

4. 创建ELB

依次为创建负载均衡、监听器、后端服务器组、添加后端member、创建健康检查

  1. neutron lbaas-loadbalancer-create –name lbname subnetname

  2. neutron lbaas-listener-create –name lisname –loadbalancer lbname –protocol UDP –protocol-port 400 protocol 可选 HTTP HTTPS TCP UDP

  3. neutron lbaas-pool-create –listener lisname –name pool_name –lb-algorithm SOURCE_IP –protocol UDP
    1. lb-algorithm 分配策略。可选 ROUND_ROBIN、LEAST_CONNECTIONS、SOURCE_IP
    2. protocol 一般同listener
    3. session_persistence ：会话保持策略，默认为空。可选
      • tcp: SOURCE_IP
      • http：HTTP_COOKIE/APP_COOKIE
  4. neutron lbaas-member-create –name mem_name –subnet subnetname –address 10.0.0.100 –protocol-port 8000 –weight 1 pool_name
    1. address 后端服务器地址
    2. weight 权重
  5. neutron lbaas-healthmonitor-create –delay 30 –max-retries 3 –timeout 3 –type TCP –pool pool_name –name health_name
    1. 创建healthmonitor要指定pool name
    2. delay 健康检查周期
    3. type可选：TCP HTTP UDP PING （新加HTTPS）
    4. http_method 可选 ‘GET’, ‘HEAD’, ‘POST’, ‘PUT’, ‘DELETE’, ‘TRACE’, ‘OPTIONS’, ‘CONNECT’, ‘PATCH’
