今天在线上环境使用cp.push模块拉取minion端文件时，出现如下错误

# salt 192.168.xxx.xxx cp.push   /etc/fstab
192.168.xxx.xxx:
    The minion function caused an exception: Traceback (most recent call last):
      File "/usr/lib/python2.6/site-packages/salt/minion.py", line 1332, in _thread_return
        return_data = executor.execute()
      File "/usr/lib/python2.6/site-packages/salt/executors/direct_call.py", line 28, in execute
        return self.func(*self.args, **self.kwargs)
      File "/usr/lib/python2.6/site-packages/salt/modules/cp.py", line 876, in push_dir
        ret = push(tmpfile, upload_path=tmpupload_path)
      File "/usr/lib/python2.6/site-packages/salt/modules/cp.py", line 799, in push
        load_path_list = os.path.split(load_path_split_drive)
      File "/usr/lib64/python2.6/posixpath.py", line 82, in split
        i = p.rfind('/') + 1
    AttributeError: 'tuple' object has no attribute 'rfind'

 

然后在测试环境使用cp.push模块正常，

# salt 192.168.62.200  cp.push /etc/fstab 
192.168.62.200:
    True

 

对比测试环境跟线上环境salt版本,

线上环境

# salt --version
salt 2016.3.3 (Boron)

测试环境

# salt --version
salt 2016.11.3 (Carbon)

 

版本不一致,对比cp模块源码，发现报错代码行前后有一些差异

将线上环境/usr/lib/python2.6/site-packages/salt/modules/cp.py 备份并删除799行代码中的冒号(:) 重新执行命令发现正常拉去minion文件

# salt 192.168.xxx.xxx cp.push   /etc/fstab

将cp.py模块推送到各个minion
