這篇文章主要給大家介紹了關(guān)于Python如何實(shí)現(xiàn)MySQL實(shí)例初始化的相關(guān)資料，文中通過示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧。

前言

相信每位程序員對(duì)mysql應(yīng)該都不陌生，MySQL是一個(gè)關(guān)系型數(shù)據(jù)庫管理系統(tǒng)，由瑞典MySQL AB 公司開發(fā)，目前屬于 Oracle 旗下產(chǎn)品。我們?cè)谌粘ｉ_發(fā)中少不了要接觸mysql。

騰訊云上的mysql實(shí)例，初始化的時(shí)候，需要自己點(diǎn)擊“初始化按鈕”，然后還要手動(dòng)輸入16位復(fù)雜的密碼，這個(gè)操作比較繁瑣，而且如果你一次建立多個(gè)實(shí)例，這個(gè)操作量就很大了，所以必須想辦法提高效率，于是就有了下文，批量調(diào)用sdk api來實(shí)現(xiàn)。

本文主要給大家介紹了關(guān)于Python實(shí)現(xiàn)MySQL實(shí)例初始化的相關(guān)內(nèi)容，分享出來供大家參考學(xué)習(xí)，下面話不多說了，來一起看看詳細(xì)的介紹吧。

示例代碼

代碼準(zhǔn)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():
 # 這里添加 N多實(shí)例id，可以批量進(jìn)行初始化，不用再界面點(diǎn)擊操作了。
 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()

初始化實(shí)例腳本initstance.py，準(zhǔn)備執(zhí)行代碼：
