ansible 就可以完成你說(shuō)的任務(wù)啊。
如果你想更多使用 python 代碼來(lái)控制流程，你可以使用另外一個(gè)自動(dòng)化部署工具 fabric

#!/usr/bin/python 

import sys
import pexpect

ip = sys.argv[1]
password = sys.argv[2]
expect_list = ['(yes/no)', 'password:']

p = pexpect.spawn('ssh-copy-id %s' % ip)
try:
    while True:
        idx = p.expect(expect_list)
        print p.before + expect_list[idx],
        if idx == 0:
            print "yes"
            p.sendline('yes')
        elif idx == 1:
            print password
            p.sendline(password)
except pexpect.TIMEOUT:
    print >>sys.stderr, 'timeout'
except pexpect.EOF:
    print p.before
    print >>sys.stderr, '<the end>'

已經(jīng)解決問(wèn)題
