gpg 加密失败：文件打开错误
我已经为此发疯了..
我在 CentOS 服务器上安装了 gnupg，并尝试加密上传的文件（通过 PHP 页面上传）。在服务器上通过命令行，它运行得很好。但是通过 php 脚本，它会失败并出现以下错误：
gpg: /path-to-my-file/my-file: encryption failed: file open error
用户 apache （我认为用于运行 exec 命令）在文件的目录中具有读/写权限。
文件上传正常（当我从代码中删除未加密文件的删除后我可以看到它）并且可以通过 php 站点正确删除。
我运行的命令如下 知道
/path-to-gpg/gpg --homedir=/path-to-my-home-gnupg/.gnupg -e -r therecipient@email the-unencrypted-file
如何解决这个问题吗？ 谢谢
I have been going nuts with this..
I have gnupg installed on my CentOS server and I try to encrypt uploaded files (uploaded via a PHP page). On the server via the command line, it works perfectly. But via the php script, it fails with this error:
gpg: /path-to-my-file/my-file: encryption failed: file open error
The user apache (which I think is used to run the exec command) has read/write in the directory of the file.
The file is uploaded fine (I can see it afterward as I removed the deletion of the unencrypted file from my code) and can be deleted correctly via the php site.
the command I run is the following
/path-to-gpg/gpg --homedir=/path-to-my-home-gnupg/.gnupg -e -r therecipient@email the-unencrypted-file
Any idea how I could tackle this?
thanks

有几件事需要检查：
system("ls " .escapeshellarg($file))并检查结果 - 是否找不到文件？没有权限？这将帮助您调试。system("whoami")以确保 PHP 按照您认为的方式运行。" 然后复制+粘贴命令并从 shell 运行它，以确保文件的路径是您期望的路径。
另外，我相信 CentOS 默认运行 SELinux…如果您安装了它，请检查日志（在
/var/log/中）以查看 SELinux 是否阻止 Apache 执行 GPG。A few things to check:
system("ls " . escapeshellarg($file))and check the result — is it file not found? Permission denied? That will help you debug.system("whoami")to make sure PHP is running as who you think it is.echo "<pre>ls " . escapeshellarg($file) . "</pre>"then copy+paste the command and run it from the shell to make sure that the path to the file is what you expected it to be.Also, I believe CentOS runs SELinux by default… If you've got it installed, check the logs (in
/var/log/) to see if SELinux is preventing Apache from executing GPG.尝试在详细模式下使用实际的 apache 用户权限运行命令：
Try running the command with actual apache user privileges in verbose mode:
