Python如何實現MySQL例項初始化詳解

前言

相信每位程式設計師對mysql應該都不陌生，MySQL是一個關係型資料庫管理系統，由瑞典MySQL AB 公司開發，目前屬於 Oracle 旗下產品。我們在日常開發中少不了要接觸mysql。

騰訊雲上的mysql例項，初始化的時候，需要自己點選“初始化按鈕”，然後還要手動輸入16位複雜的密碼，這個操作比較繁瑣，而且如果你一次建立多個例項，這個操作量就很大了，所以必須想辦法提高效率，於是就有了下文，批量呼叫sdk api來實現。

本文主要給大家介紹了關於Python實現MySQL例項初始化的相關內容，分享出來供大家參考學習，下面話不多說了，來一起看看詳細的介紹吧。

示例程式碼

程式碼準備：initstance.py

 #!/usr/bin/python
 from src.QcloudApi.qcloudapi import QcloudApi
 from time import ctime,sleep
 from getpwd import get_password

 def initinstance(cdbid,no):
 module = 'cdb'
 action = 'CdbMysqlInit'
 config = {
  'Region': 'ap-shanghai','secretId': 'AKIDTsEEl8ZK9mHcotf4OYk2A7uYxxxxxxxx','secretKey': 'IOI0Zw87vYDvhR6a5QZXouomxxxxxxxx','method': 'get'
 }

 pwd=get_password(16)
 params = {
  'cdbInstanceId': cdbid,'charset': 'utf8mb4','port': 3306,'lowerCaseTableNames': 1,'password': pwd
 }

 print params
 try:
  service = QcloudApi(module,config)
  print service.generateUrl(action,params)
  print service.call(action,params)
 except Exception,e:
  print 'exception:',e

 def main():
 # 這裡新增 N多例項id，可以批量進行初始化，不用再介面點選操作了。
 cdbids_hermes=["cdb-1hz14ogho","cdb-1417ds7su"]
 for index,value in enumerate(cdbids_hermes):
  initinstance(value,str((index+1)).zfill(2))
  sleep(1)

 if __name__ == '__main__':
 main()

初始化例項指令碼initstance.py，準備執行程式碼：
