答案1

sudo 在新的环境中启动该进程，该环境在运行命令之前默认重置。

如果机器管理员没有在 /etc/sudoers 中禁止它，您可以使用它sudo -E command来保留该命令的用户环境变量。

答案2

尽管方法有很多，但您只需按照以下步骤操作即可：

  1. sudo vi /etc/environment
  2. 在文件中添加您的环境变量：JAVA_HOME=/usr/lib/jvm/java-7-oracle/
  3. source /etc/environment
  4. 现在，$JAVA_HOME所有用户都可以访问。
  5. 执行脚本：sudo sh runxnc.sh

答案3

由于您在 sudo 中运行脚本，因此它不会采用您在 gandalf 用户中设置的环境变量。也许将环境变量添加到 /root/.bashrc 会有所帮助！
