我正在尝试通过SSH将我的python程序连接到远程MySQL数据库。
我正在使用Paramiko进行SSH和SQLAlchemy。
这是我到目前为止所做的:
import paramiko
from sqlalchemy import create_engine
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('host', port=port, username='user', password='pass')
engine = create_engine('mysql+mysqldb://user:pass@host/db')
我收到错误:
sqlalchemy.exc.OperationalError: (_mysql_exceptions.OperationalError) (2003, "Can't connect to MySQL server on 'mcsdev.croft-it.com' (60)")

抱歉,我之前发过了重复的答案。以下是针对您的问题量身定制的更详细的答案;)
如果您仍然需要通过SSH连接到远程MySQL数据库,我使用了一个名为sshtunnel的库,它包装和简化了paramiko(sshtunnel的依赖)的使用。
使用此代码,我认为你会很高兴:
from sshtunnel import SSHTunnelForwarder
from sqlalchemy import create_engine
server = SSHTunnelForwarder(
('host', 22),
ssh_password="password",
ssh_username="username",
remote_bind_address=('127.0.0.1', 3306))
server.start()
engine = create_engine('mysql+mysqldb://user:pass@127.0.0.1:%s/db' % server.local_bind_port)
# DO YOUR THINGS
server.stop()

此代码对我有用
import pymysql
import paramiko
from paramiko import SSHClient
from sshtunnel import SSHTunnelForwarder
from sqlalchemy import create_engine
#ssh config
mypkey = paramiko.RSAKey.from_private_key_file('your/user/location/.ssh/id_rsa')
ssh_host = 'your_ssh_host'
ssh_user = 'ssh_host_username'
ssh_port = 22
#mysql config
sql_hostname = 'your_mysql_host name'
sql_username = 'mysql_user'
sql_password = 'mysql_password'
sql_main_database = 'your_database_name'
sql_port = 3306
host = '127.0.0.1'
with SSHTunnelForwarder(
(ssh_host, ssh_port),
ssh_username=ssh_user,
ssh_pkey=mypkey,
remote_bind_address=(sql_hostname, sql_port)) as tunnel:
engine = create_engine('mysql+pymysql://'+sql_username+':'+sql_password+'@'+host+':'+str(tunnel.local_bind_port)+'/'+sql_main_database)
connection = engine.connect()
print('engine creating...')
sql = text(""" select * from nurse_profiles np limit 50""")
nurseData = connection.execute(sql)
connection.close()
nurseList = []
for row in nurseData:
nurseList.append(dict(row))
print('nurseList len: ', len(nurseList))
print('nurseList: ', nurseList)

ubuntu server
在数字海洋上使用ssh key
接受的答案对我不起作用,我必须指定ssh_private_key
,这是您的私钥的路径
from sqlalchemy import create_engine
from sshtunnel import SSHTunnelForwarder
server = SSHTunnelForwarder(
('133.22.166.19', 22),
ssh_password="123ABC123",
ssh_username="erfan",
ssh_private_key=r'C:\Users\Erfan\.ssh\id_rsa',
remote_bind_address=('127.0.0.1', 3306)
)
server.start()
engine = create_engine(
f'mysql+mysqldb://root:safepassword123@127.0.0.1:{server.local_bind_port}'
)
dbs = engine.execute('SHOW DATABASES;')
for db in dbs:
print(db)
server.stop()
