windows server 2016 使用 git ssh(主机密钥验证失败)

Question

I can do this in CMD under temp_npp user.However, when executed in PHP exec, it returns an error. The user that I print when I access PHP remotely is not the same as the user that I print when I execute my CMD.But I've also put the relevant.ssh files in the remote execution user's configuration directory.

Here's the code

$pro_dir = __DIR__;
$pro_dir  = iconv('utf-8', 'gb2312', $pro_dir);
echo $pro_dir;
echo "<br/>";
chdir($pro_dir);
echo "<br/>";
echo getcwd();
echo "<br/>";
echo shell_exec('echo %username% 2>&1');
echo "<br/>";
echo shell_exec('echo %userprofile% 2>&1');
echo shell_exec('echo %HOMEDRIVE% 2>&1');
echo shell_exec('echo %SYSTEMDRIVE% 2>&1');

$ssh = "\"F:\Program Files\OpenSSH\bin\ssh.exe\"  -vvv git@gitee.com 2>&1";
exec($ssh,$out2);
echo "<br/>";
print_r($out2);
$shell = "\"F:\Program Files\Git\bin\git.exe\" pull 2>&1";
exec($shell,$out);
echo "<br/>";
print_r($out);

Here are the results

Answer 1

read_passphrase: can't open /dev/tty

That suggests a private key protected by a passphrase, which cannot be entered in your non-interactive PHP session.

For testing, try and add to the "remote execution user's configuration directory" (their ~/.ssh folder) a private key without passphrase, to see if it works.
