Ansible:如何为 solaris 全局设置 PATH [英] Ansible: How to globally set PATH for solaris

问题描述

我正在编写 Ansible playbook，以便在 Solaris 服务器上设置和安装我们的应用程序.

I am writing Ansible playbooks to setup and install our applications on Solaris servers.

问题是我需要执行的 (bash) 脚本都假设某个目录位于 PATH 上，即 /data/bin - 如果它通常不会成为问题不适用于 Ansible 忽略所有 .profile 和 .bashrc 配置.

The problem is that the (bash) scripts which I need to execute all assume that a certain directory lies on the PATH, namely /data/bin - which would normally not be a problem were it not for Ansible ignoring all the .profile and .bashrc config.

现在，我知道您可以通过 environment 标志为 shell 任务指定环境，例如:

Now, I know that you can specify the environment for shell tasks via the environment flag, for example like this:

- shell: printenv
  environment:
    PATH: /usr/bin:/usr/sbin:/data/bin

这将正确路径 /data/bin 文件夹，并且 printenv 命令将正确显示(或者我的 bash 脚本将正确运行).

This will properly path the /data/bin folder, and the printenv command will correctly display (or my bash scripts would correctly run).

但是.但是有两个问题:

• 首先，必须一遍又一遍地指定环境非常烦人.我知道您可以在某些剧本基本文件变量和引用中定义环境，但是您仍然必须在每个 上设置 environment: ...shell 任务.
• 其次，上面的例子不允许我动态指定路径，例如作为 PATH: $PATH:/data/bin - 因为 Ansible 以不解析 $PATH 的方式执行此操作，因此该命令会灾难性地失败.所以基本上这将覆盖对 PATH 的任何其他更改.

• First of all it is very annoying to have to specify the environment over and over again. I know that you can define the environment in some playbook base file variable and the reference that, but you still have to set environment: ... on every single shell task.
• Secondly, the above example does not allow me to specify the path dynamically, e.g. as PATH: $PATH:/data/bin - because Ansible executes this in a way which does not resolve $PATH, thus the command fails catastrophically. So essentially this will override any other changes to PATH.

我正在寻找解决方案

• 额外的 PATH 条目应该只添加一次
• 附加的 PATH 条目不应覆盖其他任务添加的条目

• the additional PATH entry should only be added once
• the additional PATH entry should not override entries added by other tasks

附言我在 如何在 Linux 上执行此操作，但它使用了 /etc/environment 而在 Solaris 上不存在.(并且 /etc/profile 再次被 Ansible 忽略.)

P.S. I found this nice explanation on how to do this on Linux, but it makes use of /etc/environment which does not exist on Solaris. (And /etc/profile is once again ignored by Ansible.)

推荐答案

尝试将 -o SendEnv=PATH 添加到 ssh_args 在 ansible.cfg.要求

try adding -o SendEnv=PATH to ssh_args in ansible.cfg. Requires that

• 运行 ansible 的 shell 在 PATH 中有/data/bin.或者，ansible 允许您修改当前/本地 PATH 变量.
• 远程机器已正确设置AcceptEnv.
