添加一个新的providers代码目录

添加页面validate按钮可用设置

manageiq/app/assets/javascripts/controllers/ems_common/ems_common_form_controller.js

在191行 附近如下代码处添加一行代码（$scope.emsCommonModel.emstype == "aliyun" ||）

#!js

$scope.isBasicInfoValid = function() {
    if(($scope.currentTab == "default" && $scope.emsCommonModel.emstype != "azure") &&
      ($scope.emsCommonModel.emstype == "ec2" ||
      $scope.emsCommonModel.emstype == "aliyun" ||
       $scope.emsCommonModel.emstype == "openstack" && $scope.emsCommonModel.default_hostname ||
       $scope.emsCommonModel.emstype == "scvmm" && $scope.emsCommonModel.default_hostname ||
       $scope.emsCommonModel.emstype == "openstack_infra" && $scope.emsCommonModel.default_hostname ||
       $scope.emsCommonModel.emstype == "nuage_network"  && $scope.emsCommonModel.default_hostname ||
       $scope.emsCommonModel.emstype == "rhevm" && $scope.emsCommonModel.default_hostname ||
       $scope.emsCommonModel.emstype == "vmwarews" && $scope.emsCommonModel.default_hostname

添加work

添加 ManageIQ::Providers::Aliyun::CloudManager::RefreshWorker

EVM CloudManager 启用监听

ManageIQ/manageiq/config/settings.yml

https://github.com/ManageIQ/manageiq/blob/euwe-1-rc2/config/settings.yml#L1258
在这个配置文件里面添加：
:ems_metrics_collector_worker_aliyun: {}
ems_metrics_collector_woker_aliyun.png

https://github.com/ManageIQ/manageiq/blob/euwe-1-rc2/config/settings.yml#L1295
添加如下代码：
:ems_refresh_worker_aliyun: {}
ems_refresh_worker_aliyun.png

manageiq/app/models/miq_server/worker_management/monitor/class_names.rb

添加代码：
ManageIQ::Providers::Aliyun::CloudManager::MetricsCollectorWorker
ManageIQ::Providers::Aliyun::CloudManager::RefreshWorker
monitor_class_names.png

monitor_class_names_in_kill_order.png

providers中添加代码

可以参考其他providers，需要添加如下几个文件：
manageiq-providers-aliyun/app/models/manageiq/providers/aliyun/cloud_manager/metrics_collector_worker/runner.rb

manageiq-providers-aliyun/app/models/manageiq/providers/aliyun/cloud_manager/metrics_collector_worker.rb

manageiq-providers-aliyun/app/models/manageiq/providers/aliyun/cloud_manager/refresh_worker.rb

manageiq-providers-aliyun/app/models/manageiq/providers/aliyun/cloud_manager/refresher.rb

aliyun_dirctory.png

aliyun providers 读取信息

在显示套餐详细信息页面中添加aliyun providers 图标 (http://localhost:3000/flavor/show/15)###

图标存放位置：
manageiq/app/assets/images/100

图片名字：
vendor-aliyun.png

添加自动监视

manageiq/lib/miq_automation_engine/service_models

在运行我worker时候，查看evm.log文件的时候发现如下错误，

Error: [uninitialized constant MiqAeMethodService::MiqAeServiceManageIQ_Providers_Aliyun_CloudManager]
[NameError]: uninitialized constant MiqAeMethodService::MiqAeServiceManageIQ_Providers_Aliyun_CloudManager  Method:[rescue in deliver]

参考其他的provider的写法，把aliyun相关的类添加上，一个类一个文件：
MiqAeServiceManageIQ_Providers_Aliyun_CloudManager
在里面每个provider都有很多类，写到哪个类的时候可以手动添加上。

代码编写

manageiq-providers-aliyun/app/models/manageiq/providers/aliyun/cloud_manager/refresher.rb
这个文件是provider worker工作的入口，这个文件里面先搜集信息，然后保存信息，相关写法可参考amazon、openstack providers的写法

def parse_legacy_inventory(ems) # 这个方法是搜集云服务的一些信息（套餐、可用区、安全组、镜像、实例等）

def save_inventory(ems, _targets, hashes) # 这个方法保存搜集到的信息，2中保存方法

manageiq-providers-aliyun/app/models/manageiq/providers/aliyun/cloud_manager/refresh_parser.rb
这个文件是搜集信息的具体代码定义处。

def ems_inv_to_hashes #这里就是每个信息的搜集处

套餐(Flavors)

manageiq-providers-aliyun/app/models/manageiq/providers/aliyun/cloud_manager/refresh_parser.rb

def get_flavors # 具体实现参考amazon、openstack providers的写法

添加文件,可参考amazon、openstack providers的写法
manageiq-providers-aliyun/app/models/manageiq/providers/aliyun/cloud_manager/flavor.rb
添加类：
manageiq/lib/miq_automation_engine/service_models
MiqAeServiceManageIQ_Providers_Aliyun_CloudManager_Flavor

可用区(Availability Zones)

app/models/manageiq/providers/aliyun/cloud_manager/refresh_parser.rb

def get_availability_zones # 具体实现参考amazon、openstack providers的写法

添加文件,可参考amazon、openstack providers的写法
app/models/manageiq/providers/aliyun/cloud_manager/availability_zone.rb
添加类：
manageiq/lib/miq_automation_engine/service_models
MiqAeServiceManageIQ_Providers_Aliyun_CloudManager_AvailabilityZone

安全组是在NetworkManager 模块里面的，所以先提阿加 NetworkManager

添加ManageIQ::Providers::Aliyun::NetworkManager::RefreshWorker

EVM NetworkManager 启用监听

ManageIQ/manageiq/config/settings.yml

这里与上边的设置一样，在相关位置添加如下代码(大约是第1370行附近)：

:ems_refresh_worker_aliyun_network: {}

manageiq/app/models/miq_server/worker_management/monitor/class_names.rb

在2个数组中（MONITOR_CLASS_NAMES、MONITOR_CLASS_NAMES_IN_KILL_ORDER）添加如下代码：

ManageIQ::Providers::Aliyun::NetworkManager::RefreshWorker

添加 networkmanager 图标

manageiq/app/assets/images/svg
添加一个图片，名字： vendor-aliyun_network.svg
manageiq/app/assets/images/100
添加一个图片，名字： vendor-aliyun_network.png

NetworkManager代码

app/models/manageiq/providers/aliyun/network_manager.rb
app/models/manageiq/providers/aliyun/network_manager/refresher.rb
app/models/manageiq/providers/aliyun/network_manager/refresh_worker.rb
app/models/manageiq/providers/aliyun/network_manager/refresh_parser.rb
app/models/manageiq/providers/aliyun/network_manager/metrics_collector_worker.rb
app/models/manageiq/providers/aliyun/network_manager/refresh_worker/runner.rb
app/models/manageiq/providers/aliyun/network_manager/metrics_collector_worker/runner.rb

可以看到，Aliyun::NetworkManager 与 Aliyun::CloudManager 文件、代码结构差不多。具体实现也是一样的。

添加安全组(security_groups)

app/models/manageiq/providers/aliyun/network_manager/refresh_parser.rb

def get_availability_zones # 具体实现参考amazon、openstack providers的写法

添加文件,可参考amazon、openstack providers的写法
app/models/manageiq/providers/aliyun/network_manager/security_group.rb
添加类：
manageiq/lib/miq_automation_engine/service_models
MiqAeServiceManageIQ_Providers_Aliyun_NetworkManager_SecurityGroup

添加实例(Instance)

app/models/manageiq/providers/aliyun/network_manager/refresh_parser.rb

get_instances # 具体实现参考amazon、openstack providers的写法

添加文件,可参考amazon、openstack providers的写法
app/models/manageiq/providers/aliyun/cloud_manager/vm.rb 添加类：
manageiq/lib/miq_automation_engine/service_models
MiqAeServiceManageIQ_Providers_Aliyun_CloudManager_Vm

添加方法：
app/models/manageiq/providers/aliyun/cloud_manager/refresher.rb

def post_process_refresh_classes #如果没有这个方法，vm.rb将不能执行
  [::Vm]
end

这里也添加一下：
db/fixtures/miq_searches.yml

# line:43
-attributes:
     name: default_Platform / Aliyun
     description: Platform / Aliyun
     filter: !ruby/object:MiqExpression
       exp:
         "=":
           field: Vm-type
           value: ManageIQ::Providers::Aliyun::CloudManager::Vm
     search_type: default
     search_key: _hidden_
     db: Vm

- attributes: # line:1020
     name: default_Platform / Aliyun
     description: Platform / Aliyun
     filter: !ruby/object:MiqExpression
       exp:
         "=":
           field: VmCloud-type
           value: ManageIQ::Providers::Aliyun::CloudManager::Vm
     search_type: default
     search_key: _hidden_
     db: ManageIQ::Providers::CloudManager::Vm

数据库中，vms表 vendor字段的aliyun支持：
app/models/vm_or_template.rb

VENDOR_TYPES = {  # 如果没有这个，数据库将不能存储实例，数据验证失败
     "google"    => "Google",
     "aliyun"    => "Aliyun",
     "unknown"   => "Unknown"}

添加实例的开机、关机、重启功能

当在网页点击开机后，rails 会给evm 服务发送消息，由EVM 服务来完成的，

  • 添加电源操作Operations模块：
    app/models/manageiq/providers/aliyun/cloud_manager/vm/operations.rb
module ManageIQ::Providers::Aliyun::CloudManager::Vm::Operations
  extend ActiveSupport::Concern
  include_concern 'Guest'
  include_concern 'Power'
end
  • 添加Guest模块，这里是重启服务器的实现部分
    app/models/manageiq/providers/aliyun/cloud_manager/vm/operations/guest.rb
module ManageIQ::Providers::Aliyun::CloudManager::Vm::Operations::Guest
  extend ActiveSupport::Concern
  included do
    supports :reboot_guest do
      unsupported_reason_add(:reboot_guest, unsupported_reason(:control)) unless supports_control?
      unsupported_reason_add(:reboot_guest, _("The VM is not powered on")) unless current_state == "on"
    end
  end

  def raw_reboot_guest
    with_provider_connection { |connection|
      parameters = {:InstanceId => ems_ref}
      connection.RebootInstance(parameters) # retrun {"RequestId"=>"9585CF9B-9049-41A1-B42B-BE3867C26AAB"}
    }
    # Temporarily update state for quick UI response until refresh comes along
    self.update_attributes!(:raw_power_state => "reboot") # show state as suspended
  end
end
  • 添加Power模块，这里是开机、关机实现部分
    app/models/manageiq/providers/aliyun/cloud_manager/vm/operations/power.rb
module ManageIQ::Providers::Aliyun::CloudManager::Vm::Operations::Power
  extend ActiveSupport::Concern

  def raw_start
    with_provider_connection { |connection|
      parameters = {:InstanceId => ems_ref}
      connection.StartInstance(parameters)
    }
    # Temporarily update state for quick UI response until refresh comes along
    self.update_attributes!(:raw_power_state => "powering_up")
  end

  def raw_stop
    with_provider_connection { |connection|
      parameters = {:InstanceId => ems_ref}
      connection.StopInstance(parameters)
    }
    # Temporarily update state for quick UI response until refresh comes along
    self.update_attributes!(:raw_power_state => "shutting_down")
  end
end
  • 最后在vm类中添加Operations的引用
    app/models/manageiq/providers/aliyun/cloud_manager/vm.rb
include_concern 'Operations'
