Answer 1

您需要将该行添加到将在登录时获取的文件中，例如： ~/.bash_profile

Answer 2

Using export sets environment variables for current shell only. Once shell is terminated environment variables for that shell no longer exist. In order to set environment variables for all shell that are initiated you should put them in ~/.bash_profile as pointed by mailo.
