from fabric.api import *
import os

host_local = ['10.11.6.203']
host_remote1 = ['10.11.6.204']
host_remote2 = ['10.11.6.205']
host_remote = []
host_remote.extend(host_remote1)
host_remote.extend(host_remote2)
host_all = []
host_all.extend(host_local)
host_all.extend(host_remote)

#env.hosts = host_remote
env.port = xxx
env.password = 'xxx'
env.user = 'fengya'
#env.warn_only = True
env.roledefs = {
    'local': host_local,
    'remote1': host_remote1,
    'remote2': host_remote2,
    'remote': host_remote,
    'all': host_all
}

@parallel
def test():
  with cd("/tmp"):
    run("pwd")
    put("/tmp/localfile1","remotefile1",mode=0777)
  run("ls -l /tmp/remotefile1")
  sudo("touch /tmp/remotefile2",user="zhuzi")
  run("ls -l /tmp/remotefile2")
