1.当前权限不足，无法写入配置文件application/database.php

2.具体看这个：https://b.abczn.com/2017/04/01/thinkphp-5-0-lnmp%E7%8E%AF%E5%A2%83%E4%B8%8B-warning-require-open_basedir-restriction-in-effect-file-%E6%8A%A5%E9%94%99%E5%A4%84%E7%90%86/

3.我的本地解决

[HOST=c.lmyperson.com]
open_basedir=/www/wwwroot/fastadmin/:/tmp/:/proc/
[PATH=/www/wwwroot/fastadmin]
open_basedir=/www/wwwroot/fastadmin/:/tmp/:/proc/

4.ok
