我通过xshell，ssh或者telnet连接容器，都是在报错

经过查询发现，原来是容器没有安装openssh服务，openssh服务是负责ssh登录的，一坑接一坑
现在镜像有了，天下我有，安装openssh即可
查询需要看装的服务
yum search openssh

安装完毕后，还需要启动服务
systemctl restart sshd
查看是否启动成功
systemctl status sshd

telnet检测一下
telnet 10.10.20.198 2229
返回

说明端口可以连接
ssh远程登陆
但是让我输入密码，但是我创建容器之后没有地方创建密码的地方
在docker desktop点进对应的容器中创建密码
passwd
返回
sh: passwd: command not found
没有对应服务，继续安装对应服务
yum install passwd -y
安装好后
passwd
返回
Changing password for user root.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
连续输入两次需要更改的密码即可
再通过xshell远程登陆，这次没有问题，顺利登陆容器
