Hi,
Greetings. I am a beginner to Fabric and liking it. I am trying to
login to 3 remote machines and getting their "/etc/*-release". My local
machine is a windows machine where I have installed Cygwin and all the
fabric related stuff. I have generated ssh key, copied the id-rsa.pub to
authorized key and copied them over to the remote machines as well.
Despite doing them, I am unable to connect them without my password. Fabric
is asking for logging into a remote machine. What is going wrong? What is
the right way to use env.key_filename? Is there anything I have to import?
Surprisingly, it asks for my password only once. It is not asking for the
subsequent servers? Why? I do not want to do this in the command-line using
"- i" option. I want this to be in the fab file itself.
Your help is much appreciated.
A min. working example is here:
=====================================
from fabric.api import *
from fabric.operations import local, put
def dev():
env.user = 'abcd'
env.hosts = ['server01', 'server02', 'server03']
env.key_filename = ['/.ssh/id_rsa.pub']
@serial
def host_info():
print 'Checking unix release of host: ', env.hosts
run('cat /etc/*-release')
=================================
execution:
ss@WW720L46784A /cygdrive/c/SS/backup
$ fab dev host_info -i /.ssh/id_rsa.pub
[sl73caed01] Executing task 'host_info'
Checking unix release of host: ['server01', 'server02', 'server03']
[server01] run: cat /etc/*-release
[server01] Login password:
[server01] out: Red Hat Enterprise Linux Server release 5.5 (Tikanga)
[server02] Executing task 'host_info'
Checking unix release of host: ['server01', 'server02', 'server03']
[server02] run: cat /etc/*-release
[server02] out: Red Hat Enterprise Linux Server release 5.5 (Tikanga)
[server03] Executing task 'host_info'
Checking unix release of host: ['server01', 'server02', 'server03']
[server03] run: cat /etc/*-release
[server03] out: Red Hat Enterprise Linux Server release 5.5 (Tikanga)
Done.
Disconnecting from server01... done.
Disconnecting from server02... done.
Disconnecting from server03... done.
