sftp put权限不够

报错如下:

sftp> put play.zip ./
Uploading play.zip to /opt/library/./play.zip
remote open("/opt/library/./play.zip"): Permission denied

原因:
sftp登录以后当前所在目录的owner不是sftp登录者,也就是说当前目录没有write权限,so修改权限,再put上传。如下:

$ sudo chown xuyuzhu -R ./      # ssh登录以后修改目录owner
$ exit
登出
$ sftp xuyuzhu@192.168.63.9     # 重新登录sftp
xuyuzhu@192.168.63.9‘s password:
Connected to 192.168.63.9.
