无法使用 Ansible 获取 .bashrc [英] Not possible to source .bashrc with Ansible

问题描述

我可以通过 ssh 连接到远程主机并执行 source/home/username/.bashrc - 一切正常.但是，如果我这样做:

I can ssh to the remote host and do a source /home/username/.bashrc - everything works fine. However if I do:

- name: source bashrc
  sudo: no
  action: command source /home/username/.bashrc

我明白了:

failed: [hostname] => {"cmd": ["source", "/home/username/.bashrc"], "failed": true, "rc": 2}
msg: [Errno 2] No such file or directory

我不知道我做错了什么...

I have no idea what I'm doing wrong...

推荐答案

在 ansible 中使用 source 有两种选择.一种是使用shell:"命令和/bin/sh(ansible 默认值).源"被称为."在/bin/sh 中.所以你的命令是:

You have two options to use source with ansible. One is with the "shell:" command and /bin/sh (the ansible default). "source" is called "." in /bin/sh. So your command would be:

- name: source bashrc
  sudo: no   
  shell: . /home/username/.bashrc && [the actual command you want run]

请注意，您必须在获取 .bashrc b/c 之后运行命令，每个 ssh 会话都是不同的 - 每个 ansible 命令都在单独的 ssh 事务中运行.

Note you have to run a command after sourcing .bashrc b/c each ssh session is distinct - every ansible command runs in a separate ssh transaction.

您的第二个选择是强制 Ansible shell 使用 bash，然后您可以使用source"命令:

Your second option is to force Ansible shell to use bash and then you can use the "source" command:

- name: source bashrc
  sudo: no   
  shell: source /home/username/.bashrc && [the actual command you want run]
  args:
     executable: /bin/bash

最后，我会注意到，如果您使用的是 Ubuntu 或类似设备，您可能希望实际获取/etc/profile"，这更完全地模拟了本地登录.

Finally, I'll note that you may want to actually source "/etc/profile" if you're on Ubuntu or similar, which more completely simulates a local login.
