使用SSH Root登录

新的系统安装后，默认情况下禁用Debian Linux上的root登录。当您试图以root用户身份登录到Debian Linux服务器上时，会被拒绝访问。以下是示例信息：
$ ssh root@192.168.1.172 
root@192.168.1.172's 
password: Permission denied, please try again. 
root@192.168.1.172's password:

按照如下步骤启用SSH root登录：

  1. 运行以下命令配置SSH服务器：
    echo "PermitRootLogin=yes" >> /etc/ssh/sshd_config
  2. 重启SSH服务器：

    示例命令和输出：

    # /etc/init.d/ssh restart
[ ok ] Restarting ssh (via systemctl): ssh.service.

    结果：

    您可以用root用户身份使用SSH登录了。如输出以下结果，则表示登录成功：

    $ ssh root@192.168.1.172 root@192.168.1.172's password:
