fabric的兩種并行方法代碼

 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 運行 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')
