Configuring Fabric for EC2
原标题:Configuring Fabric For EC2

I am trying to create a fabfile.py so that I can deploy on EC2. I have the following in my fabfile.py:

from __future__ import with_statement
from fabric.api import *


def ec2():
    env.hosts = [ 111.111.111.111 ] 
    env.user =  ubuntu 
    env.key_filename =  /path/to/my/pem/key.pem 

def run_ls():
    run( ls -alt )

111.111.111.111 is the elastic ip of my instance, and i alway login with ubuntu, not root. when i run the following command

fab ec2 run_ls

i see the following output:

[111.111.111.111] Executing task  run_ls 
[111.111.111.111] run: ls -alt

Fatal error: Host key for 111.111.111.111 did not match pre-existing key! Server s key was changed recently, or possible man-in-the-middle attack.

Aborting.

Not sure what is going on, but I can t find to seem any great tutorials on using fabric on ec2, and I do not know how that is possible.

Update:

Looks like

env.hosts = [ 111.111.111.111 ] 

您无需实际使用URL。

env.hosts = [ mywebsite.com ]

确保你的弹性方案附属于此。 我认为,关键名称只是一个论点,但当你通过阵列时,地雷正在发挥作用:

env.user = "ubuntu"
env.key_filename = ["my_key.pem",]

或许你应当尝试使用你所邀请的公开主人姓名,如:

env.roledefs.update({
     prod : [ ec2-52-14-72-225.us-west-1.compute.amazonaws.com ],
})

You can also use the --disable-known-hosts switch to ignore this error.

ssh-keygen -R 111.111.111.111
