# fabirc 配置多組服務器 密碼與密鑰一塊兒使用 key_filename的設置

環境說明

myv myv2 是配置在/etc/hosts 的兩臺 虛擬機 虛擬機ip.

參考英文文檔

官方文檔的例子不是給的很詳細..
http://docs.fabfile.org/en/1.13/usage/env.html

實例

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from fabric.api import *

#只有 student@myv2 這個機器用的是密碼
env.hosts = ['gsx@myv','student@myv2','gsx@myv2']


# This dictionary is largely for internal use, and is filled automatically as a per-host-string password cache. Keys are full host strings and values are passwords (strings).
env.passwords = {
        'student@myv2:22':'1',
}


# http://docs.fabfile.org/en/1.13/usage/env.html
# May be a string or list of strings, referencing file paths to SSH key files to try when connecting. Passed through directly to the SSH layer. May be set/appended to with -i.
env.key_filename = ['~/.ssh/test','~/.ssh/test8']

def remoteRun():
    print "ENV %s" %(env.hosts)
    out = run('whoami')
    print "Output %s"%(out)

@hosts('gsx@myv2','gsx@myv')
def taskSelectHost():
    run('ifconfig')

測試執行

fab -f ./multi_user_and_secret.py  remoteRun taskSelectHost

說明

密碼的填寫 evn.passwords

student@myv 這個用戶是使用密碼登陸,單獨在 evn.passwords裏面配置. 注意配置的方式是 full host strings 即 用戶@IP:port 和 密碼.

密鑰的填寫 env.key_filename

gsx@myv 使用 密鑰 ./ssh/test
gsx@myv2 使用 密鑰 ./ssh/test8

將鏈接使用到的密鑰 填入 env.key_filename 列表中,密鑰填寫順序無關. 不須要hosts與 key_filename 對應起來, 也不須要長度相等 , fabric 會本身嘗試密鑰.(May be a string or list of strings, referencing file paths to SSH key files to try when connecting. Passed through directly to the SSH layer. May be set/appended to with -i.)
