网站从LNMP环境迁移到DNMP环境，访问网站时直接显示“Access denied”
其它默认站点访问文件及.php均正常，反复检查目录及用户权限均正常。
查看nginx错误日志中，发现如下错误信息：
[error] 102#102: *103 FastCGI sent in stderr: “PHP message: PHP Warning: Unknown: open_basedir restriction in effect. File(/www/www.xxx.com/wp-admin/index.php) is not within the allowed path(s): (/home/wwwroot/www.xxx.com:/tmp/:/proc/) in Unknown on line 0PHP message: PHP Warning: Unknown: failed to open stream: Operation not permitted in Unknown on line 0Unable to open primary script: /www/www.xxx.com/wp-admin/index.php (Permission denied)” while reading response header from upstream, client: 219.137.64.4, server: www.xxx.com, request: “GET /wp-admin/ HTTP/1.1”, upstream: “fastcgi://172.19.0.3:9000”, host: “www.xxx.com”
修改php.ini中的basedir参数后重启也不见效，折腾一翻后，发现站点目录下.user.ini（防跨目录）
于是打开文件发现里面的路径还是原来旧机器的!=_=，于是修改成当前正常的路径，重启Docker后解决问题！
chattr -i .user.inivi .user.inichattr +i .user.ini🙂
