php执行scp主机密钥验证失败

我正在尝试使用scp来复制文件。我使用PHP的命令shell_exec来执行此命令:

scp -i/home/raul/nueva_clave -q -v /home/raul/www/CA/app/tmp/ImagenWeb TA-adm@127.0.0.1:/home/TA-adm/images/IMG_3846.JPG 2>&1

服务器地址是127.0.0.1因为我还在开发脚本。我稍后会改变它。

我正在使用scp而不是PHP的ssh2_scp_send,因为我不想在我的proyect中写入服务器的密码。相反,我想使用公钥。但是当我在PHP中执行时,这就是结果:

如果我在终端中与我的用户执行此命令,我没有问题。我想问题是用户没人正在执行scp。我正在使用Ubuntu。

1 个答案:

答案 0 :(得分:1)

(OP在问题编辑中回答。移到这里。见Question with no answers, but issue solved in the comments (or extended in chat)

OP写道:

  

它已经解决了。我使用了以下选项:

-o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no
  

因此scp命令不会尝试将主机插入用户nobody known_host文件中scp无法创建文件,因为用户没有人没有~/.ssh}。
