带有多个参数的 Vagrant ssh [英] Vagrant ssh with multiple arguments

问题描述

我在使用 vagrant ssh 执行多个命令时遇到问题.

I am having problems executing multiple commands with vagrant ssh.

为了在 vagrant 环境中运行一些测试，我执行以下命令:

In order to run some tests in vagrant environment I execute following commands:

1. vagrant ssh 应用
2. sudo su deploy
3. cd/some/dir/for/test
4. 源 env/bin/activate
5. python manage.py test

我设法达到了第 3 点，但无法执行第 4 点.我的尝试如下:

I managed to get to point 3 but could not execute the 4th point. My attempt is as follows:

vagrant ssh app -- -t 'cd /some/dir/for/test; sudo su deploy'

但是在 sudo 命令之后，如果我再写一些命令，它们就不会被执行.

But after the sudo command if I write some more commands they are not executed.

我还需要将测试输出重定向到 vagrant 环境之外的原始 shell.

I will also need to redirect the tests output to original shell, outside the vagrant environment.

推荐答案

您可以在一个命令中完成所有操作:

you can do it all in a single command:

vagrant ssh app -- -t 'sudo -u deploy /some/dir/for/test/env/bin/python /some/dir/for/test/env/manage.py test'

在这里你可以通过给 sudo 一个参数来避免无用的 su 调用，这样它就可以使用 -u 参数.那么bin/activate命令只是在改变环境，所以你之后调用的python是来自env/bin/python的那个，所以你可以直接调用它使用其完整路径.

here you can avoid the useless su call by giving an argument to sudo so it runs a command as the given user, using the -u argument. Then the bin/activate command is only changing the environment, so the python you're calling thereafter is the one from env/bin/python, so you can directly call it using its full path.

据您所知，如果您想在单个 sudo 调用中链接由 ; 分隔的两个命令，则应在您的 sudo 命令中生成一个 shell，即: sudo sh -c运行这个；运行那个".

And for your knowledge, if you want to chain two commands separated by ; in a single sudo call, you shall spawn a shell in your sudo command, i.e.: sudo sh -c "run this; run that".
