在PHP中使用shell_exec geogig init时权限被拒绝

GeoGig是一个新的地理数据版本控制工具，它与git具有相同的功能。 我正在实现这个新工具，但是当我使用shell_exec（“geogig init”）时，我遇到了一个问题。 我在apache中设置了PATH变量，该变量指向/opt/geogig/bin，其中是geogig的二进制文件，通过该变量，我可以在php中使用命令行geogig。 我的问题是，此命令创建了本地存储库的某个部分，但得到了一个shell_exec抛出的错误：

有人有主意吗？

感谢

GeoGig正在尝试读取或写入一些文件，但用户PHP正在运行，因为该文件没有读取或写入权限。我建议您按照错误消息所说的操作，并“查看日志以了解更多详细信息”。以了解该文件是什么。

我通过使用命令行sudo visudo添加visudo解决了此问题：

secure_path=“……:/opt/geogig/bin”

在文件末尾：

www-data-ALL=NOPASSWD:ALL

在shell_exec中，我添加了“sudo geogig init”

我希望这能帮助任何面临同样问题的人

谢谢你，克里斯
