fabric 如何实现两级 ssh+切换超级用户的操作

比如:
user A on localhost--->remote1, change to superuser B--->remote C, execute command

试着在fabric里写:
sudo('ssh remote c && command', sudo_user=superuser B)
可以登入到remote C服务器里,但直接就卡在那,无法执行剩下的command

有看到资料里写使用gateway,但切换超级用户不知道怎么操作.

请问一下有什么好的实现方式? 谢谢

可以直接在remote1上运行
sudo('ssh remote C "your command", sudo_user=Superuser B)

command

Remote

用两个fabfile分开B和C的操作，先把对C的操作从A扔到B上，在A中操纵B执行fab命令

你可以看原作者的:

或者这样?

# coding=utf-8

from fabric.api import run, env
from fabric.exceptions import NetworkError

via = [('user1@server1:22', '123'),
('user2@server2:22', '456'),
('user3@serve3:22', '789')]

try:
for host, passwd in via:
env.gateway = env.host_string
env.host_string = host
env.password = passwd
run('id')

except NetworkError as e:
print e
