fabric的两种并行方法代码

1：参数 -P

 from fabric.api import *
  host1 = &＃39;root@ip1:22&＃39;
  host2 = &＃39;root@ip2:22&＃39;
 
  env.hosts = [host1, host2 ]
 
  env.passwords = {
      host1: "p1",
      host2: "p2"
  }                                                                                                                                                                                                                   
  def backup_and_cp():
      with cd("/home/**"):
          run(&＃39;ls&＃39;)

 　　然后  运行 fab -P  backup_and_cp就可以了

2：装饰器

import timefrom fabric.api import *host1 = &＃39;root@ip1:22&＃39;host2 = &＃39;root@ip2:22&＃39;
  env.hosts = [host1, host2 ]
  env.passwords = {
      host1: "p1",
      host2: "p2"
  }
  @parallel                                                                                                                                                                                                                   
  def backup_and_cp():
      with cd("/home/**"):
          run(&＃39;ls&＃39;)

运行 fab backup_and_cp就OK了
