Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password)

sftp -b batchfile username@remote_host

報錯：Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password)

因為SSH不能訪問你的authorized_keys，所以必需先認證然后才能訪問

remote_host，root登陸

# mkdir /etc/ssh/<username> 

# cp /home/<username>/.ssh/authorized_keys /etc/ssh/<username>/

# chmod 755 /etc/ssh/<username>

# chmod 600 /etc/ssh/<username>/authorized_keys

# chown -R username:username /etc/ssh/<username> 

3. 編輯配置文件/etc/ssh/sshd_config並添加下列內容

# vi /etc/ssh/sshd_config

AuthorizedKeysFile    /etc/ssh/%u/authorized_keys

4. 重啟SSH

# /etc/init.d/sshd restart
