Question

当我运行带有管道或重定向的任何命令时，它会失败。

master和minion都在Digital Ocean的新Ubuntu 14.04盒子上运行，以测试Salt。

两者都是使用引导脚本从git中提取最新分支来安装的。

这是我得到的：

# salt-call --local cmd.run "ps aux | grep hello" -l debug
[DEBUG   ] Reading configuration from /etc/salt/minion
[DEBUG   ] Using cached minion ID from /etc/salt/minion_id: XXX.XXX.XX
[DEBUG   ] Configuration file path: /etc/salt/minion
[DEBUG   ] Reading configuration from /etc/salt/minion
[DEBUG   ] Failed to import module debian_service. The exeception was No module named systemd. Another attempt will be made to try to resolve dependencies.
[DEBUG   ] compile template:
[ERROR   ] Template does not exist:
[INFO    ] Executing command 'ps aux | grep hello' in directory '/root'
[ERROR   ] Command 'ps aux | grep hello' failed with return code: 1
[ERROR   ] output: error: garbage option

Usage:
  ps [options]

  Try 'ps --help <simple|list|output|threads|misc|all>'
  or 'ps --help <s|l|o|t|m|a>'
  for additional help text.

For more details see ps(1).

没有管道它工作正常，但显然会返回完整的输出。

尝试使用python_shell=True或cmd.shell：

root@323be0968814:/# salt-call --local cmd.run "ps aux | grep hello" python_shell=True
[INFO    ] Executing command 'ps aux | grep hello' in directory '/root'
local:
    root      4796  0.0  0.1 134688 24200 ?        S+   14:50   0:00 /usr/bin/python /usr/bin/salt-call --local cmd.run ps aux | grep hello python_shell=True
    root      4819  0.0  0.0   4444   652 ?        S+   14:50   0:00 /bin/sh -c ps aux | grep hello
    root      4821  0.0  0.0   4444   104 ?        R+   14:50   0:00 /bin/sh -c ps aux | grep hello

root@323be0968814:/# salt-call --local cmd.shell "ps aux | grep hello" 
[INFO    ] Executing command 'ps aux | grep hello' in directory '/root'
local:
    root      4822  0.0  0.1 134688 24204 ?        S+   14:52   0:00 /usr/bin/python /usr/bin/salt-call --local cmd.shell ps aux | grep hello
    root      4845  0.0  0.0   4444   648 ?        S+   14:52   0:00 /bin/sh -c ps aux | grep hello
    root      4847  0.0  0.0   4444   100 ?        R+   14:52   0:00 /bin/sh -c ps aux | grep hello

来自the cmd.run docs（强调我的）：

警告：此函数不通过shell处理命令除非python_shell标志设置为True。 这意味着任何特定于shell的功能，例如'echo'或使用管道，重定向或＆amp;＆amp;，应该迁移到cmd.shell或具有 python_shell =此处设置了真正的标志。

Salt无法使用管道或重定向执行命令
