通常,为了安全性,数据库只允许通过ssh来访问。例如:mysql数据库放在服务器A上,只允许数据库B来访问,这时,我们需要用机器C去访问数据库,就需要用C通过ssh连接B,再访问A。

import pymysql from sshtunnel import SSHTunnelForwarder with SSHTunnelForwarder( (sshServerB_ip, sshServerB_port), # B机器的配置 ssh_password = sshServerB_pwd, ssh_username = sshServerB_usr, remote_bind_address = (databaseA_ip, databaseA_port)) as server: # A机器的配置 db_connect = pymysql.connect(host = '127.0.0.1' , # 此处必须是是127.0.0.1 port = server.local_bind_port, user = databaseA_usr, passwd = databaseA_pwd, db = databaseA_db) cur = db_connect.cursor() cur.execute( 'call storedProcedure' ) db_connect.commit() |
以下是自己进行事务管理,并使用peewee框架:
