3.10. 在 Azure 中启动并连接到 RHEL 虚拟机

流程

1. 创建虚拟机：

   $ az vm create \
       -g <resource_group> -l <azure_region> -n <vm_name> \
       --vnet-name <vnet_name> --subnet <subnet_name> --size Standard_A2 \
       --os-disk-name <simple_name> --admin-username <administrator_name> \
       --generate-ssh-keys --image <path_to_image>

   示例:

   $ az vm create \
   -g azrhelclirsgrp2 -l southcentralus -n rhel-azure-vm-1 \ 

   1

   
   --vnet-name azrhelclivnet1 --subnet azrhelclisubnet1 --size Standard_A2 \
   --os-disk-name vm-1-osdisk --admin-username clouduser \ 

   2

   
   --generate-ssh-keys --image rhel10
   
   {
     "fqdns": "",
     "id": "/subscriptions//resourceGroups/azrhelclirsgrp/providers/Microsoft.Compute/virtualMachines/rhel-azure-vm-1",
     "location": "southcentralus",
     "macAddress": "",
     "powerState": "VM running",
     "privateIpAddress": "10.0.0.4",
     "publicIpAddress": "<public_ip_address>",
     "resourceGroup": "azrhelclirsgrp2"
   }

   1

   --generate-ssh-keys 选项会在 ~/.ssh 目录中创建一个私钥和公钥对文件。

   2

   公钥被添加到 --admin-username 选项所指定的用户的虚拟机上的 authorized_keys 文件中。

   详情请参阅 SSH 验证方法的类型。请注意 publicIpAddress，您需要在下一步中登录到虚拟机。

2. 启动 SSH 会话并登录到 Azure 虚拟机：

   [clouduser@localhost]$ ssh -i /home/clouduser/.ssh/id_rsa clouduser@<public_ip_address>
   
   The authenticity of host '<public_ip_address>' can't be established.
   Are you sure you want to continue connecting (yes/no)? yes
   Warning: Permanently added '<public_ip_address>' (ECDSA) to the list of known hosts.
