Python如何实现MySQL实例初始化详解
前言
相信每位程序员对mysql应该都不陌生，MySQL是一个关系型数据库管理系统，由瑞典MySQL AB 公司开发，目前属于 Oracle 旗下产品。我们在日常开发中少不了要接触mysql。
腾讯云上的mysql实例，初始化的时候，需要自己点击“初始化按钮”，然后还要手动输入16位复杂的密码，这个操作比较繁琐，而且如果你一次建立多个实例，这个操作量就很大了，所以必须想办法提高效率，于是就有了下文，批量调用sdk api来实现。
本文主要给大家介绍了关于Python实现MySQL实例初始化的相关内容，分享出来供大家参考学习，下面话不多说了，来一起看看详细的介绍吧。
示例代码
代码准备：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():
# 这里添加 N多实例id，可以批量进行初始化，不用再界面点击操作了。
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()
初始化实例脚本initstance.py，准备执行代码：
