解决办法

[root@cent ~]# yum -y remove openssh-server
[root@cent ~]# yum -y install openssh-server

2、生成密钥(可选)

[root@cent ~]# sshd-keygen

3、修改sshd_config配置文件

[root@cent ~]# vim /etc/ssh/sshd_config

# 添加以下内容至文件末尾处 :wq
PubkeyAuthentication yes

4、重新启动sshd

[root@cent ~]# systemctl restart sshd.service
