我知道这是一篇过时的文章，OP可能已经亲自解决了这个问题，但对于其他人来说:

I know this is an old post and the OP already may has solved this by himself but for others:

SetEnv ENVIRONMENT setting

这将是httpd.conf文件中正确的语法.另外，此代码应放在文件末尾.

This would be the correct Syntax inside of the httpd.conf file. Also, this code should be put at the end of the file.

保存httpd.conf后，需要重新启动apache服务器.否则，将不会在此" apache会话中设置环境变量！

After saving httpd.conf the apache server needs to be restarted. Otherwise the environment variable will not be set in "this" apache session!

此致， 杨嘉美
