Python操做騰訊雲CVM

1、背景

客戶有需求在非工做時間將騰訊雲CVM停機，工做時間又開起來，中止能夠在系統內寫定時任務來，但啓動須要在騰訊雲平臺，就須要使用騰訊雲的API來進行操做，還好騰訊雲SDK for Python ，簡單記錄下。

2、代碼

git 地址
核心代碼

• CVM操做

  class CvmOper():
  def __init__(self,logger):
      config = configparser.ConfigParser()
      config.read('config.py',encoding='utf-8')
      self.instance_list = config['common']['InstanceIds'].split(',')
      print(self.instance_list)
      cred = credential.Credential(config['common']['SecretId'], config['common']['SecretKey'])
      self.clentoper = cvm_client.CvmClient(cred, config['common']['Region'])
  
      self.logger = logger
      self.logger.info("------------------------start cvm of API log-------------")
  def reboot_instance(self):
      """
      重啓cvm
      :return:
      """
      # 設置參數
      request = models.RebootInstancesRequest()
      request.InstanceIds=self.instance_list
      # 發起請求
      response = self.clentoper.RebootInstances(request)
      self.logger.info("public ecs *** reboot successful!")
      self.logger.info(response.to_json_string())
      print(response.to_json_string())

• 配置文件

[common]
# 騰訊雲secretid
SecretId = AKIDjPYbTBU4FF4iAQuxxxxxxxxxxxxxxxxxxxxx
# 騰訊雲secretkey
SecretKey = e7RaXYVP63rUvBNUQxxxxxxxxxxxxxxxx
# cvm 所在地域
Region = ap-shanghai

# 騰訊雲cvm實例id，多個用,隔開
InstanceIds = ins-h8dxxxx

• 日誌記錄

class CvmLog:
    def __init__(self,filename):
        self.filename = filename
    def createDir(self):
        _LOGDIR = os.path.join(os.path.dirname(__file__), 'cvmlog')
        print(_LOGDIR)
        _TIME = time.strftime('%Y-%m-%d', time.gmtime()) + '-'
        _LOGNAME = _TIME + self.filename
        print(_LOGNAME)
        LOGFILENAME = os.path.join(_LOGDIR, _LOGNAME)
        print(LOGFILENAME)
        if not os.path.exists(_LOGDIR):
            os.mkdir(_LOGDIR)
        return LOGFILENAME

    def createlogger(self,logfilename):
        logger= logging.getLogger()
        logger.setLevel(logging.INFO)
        handler = logging.FileHandler(logfilename)
        handler.setLevel(logging.INFO)
        formater = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
        handler.setFormatter(formater)
        logger.addHandler(handler)
        return logger

3、測試

• 單獨執行
  
  

• 配合定時任務部署在服務器上
  使用Python2.7 ，建議使用centos7以上不用單獨安裝python，默認版本便可操做

  git clone https://github.com/redhatxl/my-python-code.git /usr/local/pythoncode

  配置好config.py中騰訊雲平臺的信息後（建議建立單個子用戶，爲子用戶僅受權操做的cvm實例獲取其secretid，secretkey），製做定時任務
  

• 查看日誌
