在PHP脚本上验证生成的bitbucket ssh密钥

在VPS ssh中，我将：

我不知道它怎么了。在SSH、PHP-CLI上可以，但在Web服务器上不工作，请帮助。谢谢

apache用户www数据没有对包含用户ssh密钥的文件的读取权限，因此无法执行该命令，因为linux正试图通过CGI使用用户www数据执行该命令

至于执行官“whoami”；和exec'echo~。$user；命令，我认为您当前正在直接运行它们，尝试从PHP文件中运行它们并通过Web服务器执行，您肯定会看到不同的用户

因此，如前所述，为apache用户生成一个ssh密钥

并在您的bitbucket帐户上添加具有只读访问权限的公钥。

这是因为默认情况下，ssh将在您的主目录、管理员的主目录中尝试查找您的ssh密钥

当您通过apache执行它时，脚本在远离admin的主目录下运行。虽然您可以通过命令行ssh-i/path/to/key将路径传递给密钥，但将apache读取权限授予admin的密钥是非常不安全的

我将创建一个单独的ssh密钥，并仅将其用于bitbucket读取访问。然后将其放入apache可访问的文件夹中，但不能通过web浏览

现在可以使用以下shell_exec调用来测试连接：

<?php echo shell_exec("ssh -i /path/to/key -vT git@bitbucket.org 2>&1");?>

我生成了两个ssh密钥，一个用于admin，另一个用于www-data-apache-user，我将它们放在bitbucket用户设置中，它就工作了！谢谢你的回复

<?php echo exec("ssh -vT git@bitbucket.org 2>&1");?>

exec('whoami'); //admin
exec('echo ~'.$user); // /home/admin

sudo -u apache ssh-keygen -t rsa

<?php echo shell_exec("ssh -i /path/to/key -vT git@bitbucket.org 2>&1");?>
