在Ruby on Rails应用中执行sudo命令 [英] Execute a sudo command in Ruby on Rails app

问题描述

我正在尝试从Ruby on Rails应用程序执行以下命令:

I am trying to execute a command like this from a Ruby on Rails app:

sudo服务squid3重新启动

sudo service squid3 restart

如果我尝试使用此代码:

If i try it with this code:

output = ´sudo service squid3 retsart´

它不起作用，在控制台中，我看到linux询问密码. 如何使用此命令传递密码?或其他建议...

It don't work, in the console i see that linux asks the password. How can i pass a password with this command? Or other suggestions...

推荐答案

如果系统上可用，请尝试使用sudo -S标志(请检查man):

You can try the sudo -S flag if available on you system (check man):

echo secretPasswd | sudo -S service squid3 restart

这意味着密码将是透明的，因此您可以将需要执行该任务的用户添加到sudoers中(顺便说一句，这会引起另一个安全问题).

This means that the password will be in clear so you can add the user which needs to perform the task to the sudoers (which creates another security issue by the way).
