docker安装Ubuntu20及开启ssh连接

docker安装Ubuntu20及ssh连接

创建一个新的ubuntu容器

sudo docker run --name ubuntu -i -t -d -p 3324:22 homebrew/ubuntu20.04:4.0.20

admin@ubuntu:~$ sudo docker ps
CONTAINER ID   IMAGE                         COMMAND                  CREATED         STATUS          PORTS                                                                                                  NAMES
907e1cb9b00c   homebrew/ubuntu20.04:4.0.20   "/bin/bash"              4 minutes ago   Up 4 minutes    0.0.0.0:3324->22/tcp                                                                                   ubuntu                                                                                ubuntu

进入docker容器

admin@ubuntu:~$ sudo docker exec -it ubuntu /bin/bash
linuxbrew@907e1cb9b00c:~$ 

更新软件源为最新版

linuxbrew@907e1cb9b00c:~$ sudo apt-get update

安装openssh

linuxbrew@907e1cb9b00c:~$ sudo apt-get install openssh-server

安装vim

linuxbrew@907e1cb9b00c:~$ sudo apt-get install vim

修改ssh配置，允许ssh不限制登录方式

sudo vim /etc/ssh/sshd_config

#LoginGraceTime 2m
#PermitRootLogin prohibit-password
PermitRootLogin yes
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10

启动ssh服务

linuxbrew@907e1cb9b00c:~$ sudo /etc/init.d/ssh start
 * Starting OpenBSD Secure Shell server sshd                                [ OK ] 

修改当前用户密码

linuxbrew@907e1cb9b00c:~$ sudo passwd linuxbrew
New password: 
Retype new password: 
passwd: password updated successfully

切换到root用户，并修改root密码

linuxbrew@907e1cb9b00c:~$ sudo su root
root@907e1cb9b00c:/home/linuxbrew# 
root@907e1cb9b00c:/home/linuxbrew# passwd
New password: 
Retype new password: 
passwd: password updated successfully

然后便可以通过ssh连接了，注意连接的端口是：3324
