我就废话不多说了，大家还是直接看代码吧~

import pymysqlfrom sshtunnel import SSHTunnelForwarderimport pymysql.cursors #以dict形式输出def dbconnect_ssh(ssh_host,ssh_port,keyfile,ssh_user,db_host,db_name,sql,db_port,db_user,db_passwd): with SSHTunnelForwarder( (ssh_host, ssh_port), #ssh_password="sshpasswd", ssh_pkey=keyfile, ssh_username=ssh_user, remote_bind_address=(db_host, db_port) ) as server: db = pymysql.connect( host='127.0.0.1', port=server.local_bind_port, user=db_user, passwd=db_passwd, db=db_name, charset="utf8", cursorclass=pymysql.cursors.DictCursor) cursor = db.cursor() try: cursor.execute(sql) data = cursor.fetchall() db.commit() except: db.rollback() collect = [] for result in data: collect.append(result) db.close() cursor.close() return collectif __name__ == "__main__": ssh_host = "10.10.2.13" #SSH服务器地址 ssh_port = 22 #SSH端口 keyfile = xxxx.key" #SSH密钥 ssh_user = "root" #SSH用户名 db_host = "127.0.0.1" #数据库地址 db_name = 'DBname' #数据库名 sql = 'show tables;' #SQL db_port = 3306 #数据库端口 db_user = 'root' #数据库用户名 db_passwd = '33333' #数据库密码 result = dbconnect_ssh(ssh_host,ssh_port,keyfile,ssh_user,db_host,db_name,sql,db_port,db_user,db_passwd) print (result)

补充知识：Python 使用SSHTunnel 连接内网mysql数据库

准备：

主要模块 sshtunnel， pip install sshtunnel

其余模块 pymysql，playhouse，configparser

简介：

这里用的是数据库连接池和自动的链接断开重连机制，其实最主要的就是sshtunner的建立，所以可以只看service建立的 部分

配置文件：

[mysql]database=ad_insightmax_connections=10stale_timeout=1000host=localhostuser=数据库用户名password=数据库密码port=3306

python 代码

from playhouse.pool import PooledMySQLDatabasefrom playhouse.shortcuts import ReconnectMixinfrom configparser import ConfigParserfrom sshtunnel import SSHTunnelForwarder class RetryMySQLDatabase(ReconnectMixin,PooledMySQLDatabase): _instance = None @staticmethod def get_db_instance(): if not RetryMySQLDatabase._instance: server = SSHTunnelForwarder( ssh_address_or_host='ssh域名或者地址', ssh_port=ssh端口, ssh_password='ssh密码', ssh_username='ssh名称', remote_bind_address=('数据库地址',数据库端口) ) server.start() config = ConfigParser() config.read("./default.cfg",encoding="utf-8") RetryMySQLDatabase._instance = RetryMySQLDatabase( str(config['mysql']['database']), max_connections=int(config['mysql']['max_connections']), stale_timeout=int(config['mysql']['stale_timeout']), host=str(config['mysql']['host']), user=str(config['mysql']['user']), password=str(config['mysql']['password']), port=server.local_bind_port # port=int(config['mysql']['port']) ) return RetryMySQLDatabase._instance

其实主要是在server对象的建立和server.start

希望能给大家一个参考，本人亲测有效。也希望大家多多支持。
