我刚刚安装了 Debian 8.6。我想为所有用户设置 http 代理环境变量,所以我/etc/environment
按照以下指南进行编辑Debian 的维基。但是,重新启动后,仅设置 root 用户的环境变量。
这是我的/etc/environment
内容:
http_proxy=http://localhost:8123/
https_proxy=http://localhost:8123/
ftp_proxy=http://localhost:8123/
no_proxy="localhost,127.0.0.1,localaddress,.localdomain.com"
HTTP_PROXY=http://localhost:8123/
HTTPS_PROXY=http://localhost:8123/
FTP_PROXY=http://localhost:8123/
NO_PROXY="localhost,127.0.0.1,localaddress,.localdomain.com"
我通过以下方式检查结果:
echo $http_proxy
当使用 root 以 root 身份登录时sudo su
,它会给出正确的结果(http://localhost:8123/
),但是当使用普通用户时,不会设置变量。我还使用 . 检查所有环境变量env
。
更新:
更多的测试来了。
我添加SET_BY_ETC_ENVIRONMENT="hello"
到/etc/environment
,export SET_BY_ETC_PROFILE="hello"
到/etc/profile
和export SET_BY_HOME_PROFILE="hello"
到/home/perqin/.profile
。
结果如下:
user | login via | SET_BY_ETC_ENVIRONMENT | SET_BY_ETC_PROFILE | SET_BY_HOME_PROFILE
-------|------------------------------|------------------------|--------------------|--------------------
perqin | GUI | no | no | no
root | GUI | no | no | no
perqin | sudo su in terminal from GUI | yes | no | no
root | su in terminal from GUI | yes | no | no
perqin | ssh | yes | yes | yes
root | ssh | yes | yes | no
所以profile
只是在ssh登录时执行。而且它们都没有在 GUI 中应用!我正在使用 Debian 8.6 和 LXDE 桌面环境。
