导读：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 21 服务器地址是127.0.0.1,因为我还在开发脚本.我稍

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.

解决方法

(OP在一个问题编辑中回答.移到这里.见 Question with no answers,but issue solved in the comments (or extended in chat))

OP写道：

It’s SOLVED. I’ve used the options:

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

so the scp command doesn’t try to insert the host in the file known_host file of the user nobody (scp can’t create the file because the user nobody has no home neither ~/.ssh).
