设置adminPassword无效; linux部署在Azure资源管理器中

问题描述 投票：0回答：1

我正在使用ARM模板来部署linux机器。在我的Microsoft.Compute/virtualMachines部署中，我有包括这个属性（以下the docs）

    "osProfile": {
        "computerName": "computer-name-here",
        "adminUsername": "[parameters('AdminUserName')]",
        "adminPassword": "password following rules here",
        "linuxConfiguration": {
           "disablePasswordAuthentication": false
        }
        "secrets": []
    },

问题是使用该用户名和密码登录不适用于VM。

当机器旋转时，ssh user@host失败，说公钥验证失败。当我使用特殊标志强制要求输入密码时，结果相同。

当我检查VM的自动化脚本时，我看到我的属性已经通过，但缺少adminPassword。我假设他们正在从控制台中删除它以确保安全性，但是SSH客户端肯定会让它看起来像忽略了我配置的参数并只启用了ssh密钥访问。

是否可以使用Azure登录用户名/密码，或者我错过了什么？

编辑更多细节：

生成我的osProfile的方式是通过一个模板执行此操作:(注意我在用户名前加上“密码”以确保替换是正确的）

    "authConfig-sshpublickey": {
        "adminUsername": "[concat('pubkey-',parameters('AdminUserName'))]",
        "adminPassword": "",
        "linuxConfiguration": {
            "disablePasswordAuthentication": true,
            "ssh": {
                "publicKeys": [
                    {
                        "path": "[concat('/home/', parameters('AdminUserName'),'/.ssh/authorized_keys')]",
                        "keyData": "[parameters('AdminCredential')]"
                    }
                ]
            }
        }
    },
    "authConfig-password": {
        "adminUsername": "[concat('password-',parameters('AdminUserName'))]",
        "linuxConfiguration": null,
        "adminPassword": "[parameters('AdminCredential')]"
    },
    "authConfig": "[variables(concat('authConfig-',parameters('AdminAuthType')))]"

然后我在VM中设置它，如下所示：

    "osProfile": {
        "computerName": "[concat(variables('namePrefixes').vm, '-', copyIndex())]",
        "adminUsername": "[variables('authConfig').adminUsername]",
        "adminPassword": "[variables('authConfig').adminPassword]",
        "linuxConfiguration": "[variables('authConfig').linuxConfiguration]"
    },

因为在运行时我使用的是AdminAuthType = password，所以它正在进行替换。

我运行模板，它正确设置了我的所有基础架构，然后我进入Azure控制台，检查生成的VM的自动化脚本，我看到了：

            "osProfile": {
                "computerName": "[parameters('extra stuff here')]",
                "adminUsername": "password-myuser",
                "linuxConfiguration": {
                    "disablePasswordAuthentication": false
                },
                "secrets": []
            },

所以，结论：

  1. 它取代了密码验证
  2. 当我明确告诉它时，它正在插入linuxConfiguration。
  3. adminPassword没有显示在自动化脚本中，但如前所述，我不确定这是出于安全原因，还是从未真正实现过。

确切的答案是肯定的，可以通过Azure上的用户名/密码登录。使用您发布的模板，您可以忽略属性“linuxConfiguration”和“secrets”。简单的模板可以是这样的：

"osProfile": {
                    "computerName": "[variables('vmName')]",
                    "adminUsername": "[parameters('adminUsername')]",
                    "adminPassword": "[parameters('adminPassword')]"
                },

没有属性“linuxConfiguration”，因此不会配置ssh密钥。以及下面的整个模板示例：

此外，NSG规则将检查它是否允许流量。希望这会帮助你。

更新

使用密码创建VM时，创建VM后模板中的密码配置如下所示，由于安全性，您无法看到密码：

如果使用公共ssh密钥创建VM，它将是这样的：

您可以在用于创建VM的模板中设置两种身份验证方式。请选择一个来设置。如果您选择密码，请按照我上面发布的模板进行操作。
