Python Fabric Laibrary ssh连接

Question

I am unable to understand how should I set username, password, ip and port for my remote host in python fabric. I followed this . But the docs only explains like below:

from fabric.api import run
from fabric.api import env

env.hosts = [
    'newyork',
    'seattle',
    'localhost',
    ]

def host_type():
    run('uname -s')

def diskspace():
    run('df')

I wonder how they are connecting to the hosts network etc without giving any connection or credential information?

Have you checked: http://docs.fabfile.org/en/1.10/usage/fab.html

You should use as a rule of thumb in SSH, SSH keys not password.

from fabric import env
env.hosts = ['user1@host1:port1', 'user2@host2.port2']
env.passwords = {'user1@host1:port1': 'password1', 'user2@host2.port2': 'password2'}
