fabric的兩種並行方法代碼

fabric是一種python類庫，基於ssh協議的命令列工具用於應用部署和系統任務管理，下面來說一下fabric代碼並行啟動並執行兩種方式：

1：參數 -P

 from fabric.api import *  host1 = 'root@ip1:22'  host2 = 'root@ip2:22'   env.hosts = [host1, host2 ]   env.passwords = {      host1: "p1",      host2: "p2"  }                                                                                                                                                                                                                     def backup_and_cp():      with cd("/home/**"):          run('ls')

 　　然後  運行 fab -P  backup_and_cp就可以了

2：裝飾器

import timefrom fabric.api import *host1 = 'root@ip1:22'host2 = 'root@ip2:22'  env.hosts = [host1, host2 ]  env.passwords = {      host1: "p1",      host2: "p2"  }  @parallel                                                                                                                                                                                                                     def backup_and_cp():      with cd("/home/**"):          run('ls')

運行 fab backup_and_cp就OK了
