4.10. 创建 HA 节点模板实例和 HA 节点

从快照配置了镜像后，您可以创建节点模板。使用此模板来创建所有 HA 节点。完成以下步骤以创建模板和 HA 节点。

步骤

  1. 创建实例模板。 

    $ gcloud compute instance-templates create InstanceTemplateName --can-ip-forward --machine-type n1-standard-2 --image ConfiguredImageFromSnapshot --service-account ServiceAccountEmailAddress

    Example: 

    [admin@localhost ~] $ gcloud compute instance-templates create rhel-91-instance-template --can-ip-forward --machine-type n1-standard-2 --image rhel-91-gcp-image --service-account account@project-name-on-gcp.iam.gserviceaccount.com
Created [https://www.googleapis.com/compute/v1/projects/project-name-on-gcp/global/instanceTemplates/rhel-91-instance-template].
NAME  MACHINE_TYPE   PREEMPTIBLE  CREATION_TIMESTAMP
rhel-91-instance-template   n1-standard-2          2018-07-25T11:09:30.506-07:00

  2. 在一个区域中创建多个节点。 

    # gcloud compute instances create NodeName01 NodeName02 --source-instance-template InstanceTemplateName --zone RegionZone --network=NetworkName --subnet=SubnetName

    Example: 

    [admin@localhost ~] $ gcloud compute instances create rhel81-node-01 rhel81-node-02 rhel81-node-03 --source-instance-template rhel-91-instance-template --zone us-west1-b --network=projectVPC --subnet=range0
Created [https://www.googleapis.com/compute/v1/projects/project-name-on-gcp/zones/us-west1-b/instances/rhel81-node-01].
Created [https://www.googleapis.com/compute/v1/projects/project-name-on-gcp/zones/us-west1-b/instances/rhel81-node-02].
Created [https://www.googleapis.com/compute/v1/projects/project-name-on-gcp/zones/us-west1-b/instances/rhel81-node-03].

rhel81-node-02  us-west1-b  n1-standard-2               10.10.10.5   192.230.81.253  RUNNING
