fabric的两种并行方法代码

 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')

 　　然后  运行 fab -P  backup_and_cp就可以了

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')
