解决方法

1.经过yum删除现有的openssh-server，而后从新安装openssh-server

 

1. #yum -y remove openssh-server

2. #yum -y install openssh-server

2.设置密钥

#

#sshd-keygen

 

3.修改sshd_config配置文件中的PubkeyAuthentication选项，设置该选项值为yes

vim /etc/ssh/sshd_config

PubkeyAuthentication yes

4.启动sshd

 

#/usr/sbin/sshd

 

5.经过其余服务器链接该container

1. [root@centos-cloudera-1 ~]# ssh 10.10.200.4
