使用SUDO时如何保持环境变量 [英] How to keep Environment Variables when Using SUDO

问题描述

当我使用sudo命令时，环境变量不存在。例如，在设置HTTP_PROXY之后，命令 wget 可以正常工作，而没有 sudo 。但是如果我键入 sudo wget ，它表示它不能绕过代理设置。

解决方案

诀窍是通过 sudo visudo 命令将环境变量添加到 sudoers 文件，并添加以下行：

 默认值env_keep + =ftp_proxy http_proxy https_proxy no_proxy
   ArchLinux wiki 的p> 
 
 
 
 
 
 
对于Ubuntu 14，您需要在单行中指定，因为它返回多变量行的错误：
 默认值env_keep + =http_proxy
默认值env_keep + =https_proxy
默认值env_keep + =HTTP_PROXY
默认值env_keep + =HTTPS_PROXY
  
 
When I use any command with sudo the enviroment variables are not there. For example after setting HTTP_PROXY the command wget works fine without sudo. However if I type sudo wget it says it can't bypass the proxy setting.
解决方案
The trick is to add environment variables to sudoers file via sudo visudo command and add these lines:
Defaults env_keep += "ftp_proxy http_proxy https_proxy no_proxy"
taken from ArchLinux wiki.

For Ubuntu 14, you need to specify in separate lines as it returns the errors for multi-variable lines:  
Defaults  env_keep += "http_proxy"
Defaults  env_keep += "https_proxy"
Defaults  env_keep += "HTTP_PROXY"
Defaults  env_keep += "HTTPS_PROXY"
