大家好，小弟目前公司需要透過ssh跳板機連到資料庫，而且是用公私鑰的方式 有google很多網頁資料，但試了很多結果都不行，想知道問題到底出在哪，以下是程式碼 ------------------------------------------------------- import pymysql from sshtunnel import SSHTunnelForwarder with SSHTunnelForwarder( ssh_address_or_host = ('ssh跳板機的位址',22), ssh_username = '跳板機使用者帳號', ssh_pkey = '私鑰的絕對路徑', remote_bind_address = ('資料庫位址', 3306) ) as server: conn = pymysql.connect( user = '資料庫使用者帳號', password = '資料庫使用者密碼', database = '資料庫名稱', port = server.local_bind_port, charset = 'utf8') cur = conn.cursor() sql = 'SELECT VERSION()' cur.execute(sql) data = cur.fetchone() print(data) 執行後出現以下錯誤訊息 --------------------------------------------------------------------------- ValueError Traceback (most recent call last) <ipython-input-9-5452d8f5b19d> in <module> 6 ssh_username = 'ycchiang', 7 ssh_pkey = '/Users/ycchiang/.ssh/id_rsa', ----> 8 remote_bind_address = ('int-db.data-test.internal', 3306) 9 ) as server: 10 conn = pymysql.connect( ~/anaconda3/lib/python3.7/site-packages/sshtunnel.py in __init__(self, ssh_address_or_host, ssh_config_file, ssh_host_key, ssh_password, ssh_pkey, ssh_private_key_password, ssh_proxy, ssh_proxy_enabled, ssh_username, local_bind_address, local_bind_addresses, logger, mute_exceptions, remote_bind_address, remote_bind_addresses, set_keepalive, threaded, compression, allow_agent, host_pkey_directories, *args, **kwargs) 903 allow_agent=allow_agent, 904 host_pkey_directories=host_pkey_directories, --> 905 logger=self.logger 906 ) 907 ~/anaconda3/lib/python3.7/site-packages/sshtunnel.py in _consolidate_auth(ssh_password, ssh_pkey, ssh_pkey_password, allow_agent, host_pkey_directories, logger) 1094 1095 if not ssh_password and not ssh_loaded_pkeys: -> 1096 raise ValueError('No password or public key available!') 1097 return (ssh_password, ssh_loaded_pkeys) 1098 ValueError: No password or public key available! 請大大們幫忙解惑～ 如果是用command line的方式可以正確連線，只是想知道上面這種方式該怎麼處理 謝謝各位。 --
