Django通过ssh跳转连接mysql，setting.py设置

server = SSHTunnelForwarder(
    ssh_address_or_host='33.103.212.66',  # 跳板机B地址
    ssh_port=22,  # 跳板机B端口
    ssh_username='root',
    ssh_password='crmQ@cI@voBe%k!fNdffdafdfsdf',
    # local_bind_address=('127.0.0.1', 22),  # 这里必须填127.0.0.1
    remote_bind_address=('10.111.12.123', 3306) # 目标机器A地址，端口
)
server.start()
