警告:file_exists()[function.file-exists]:open_basedir限制生效.文件(在/ usr /本地/ Apache /斌/的apachectl)

首先,对不起长标题,我从未预料到这个错误,所以我不知道如何形容它.

我收到这个错误:

Warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(/usr/local/apache/bin/apachectl) is not within the allowed path(s): (/home/:/backup/:/tmp/) in /home/xxxxx/public_html/plugins/system/jch_optimize/jchoptimize/helper.php on line 176

是否意味着tmp目录中的某些内容已被使用或缺少某些内容？

我迷失在这里,我可以从哪里开始？

这是helper.php:

open_basedir 是一种服务器配置安全措施,用于禁止在webroot之外进行文件访问(通常).

这可以防止脚本读取服务器上的随机文件.如果您的服务器已经受到损害,open_basedir可以帮助减少妥协的影响.

一般来说这是一件好事,但你似乎想要做一些有点可疑的事情.

看看你的php.ini,httpd.conf你可以在那里禁用它.

看起来这个脚本想要检查某个插件的文件夹.这是不好的做法,使用apache_get_modules是正确的.您只需删除有问题的代码即可.

这个脚本甚至尝试了shell_exec,这就是为什么你必须非常小心你在互联网上找到的随机代码.在这种情况下,它不是恶意的,但只是很奇怪.
