I am only used to using the Centos system, but it is very troublesome and inconvenient to compile and install some software, but it becomes easy and convenient in Ubuntu, so I plan to use docker to run the Ubuntu system to make up for the shortcomings and shortcomings of Centos;
Project address : https://hub.docker.com/_/ubuntu/
1. Install the Ubuntu system command:
docker pull ubuntu
This is an extremely streamlined system, without even the most basic wget command; so first, apt-get update is required to upgrade the system and install the apt-get install wget command;
2. Run the command to enter the Ubuntu system:
docker run -ti ubuntu bash
3. The correct way to exit the system :
press first, ctrl+p
and then press, ctrl+q
must not use exit or ctrl+d to exit, so the whole system will exit! ! !
4. Share the host directory to the Ubuntu system:
docker run -it -v /AAA:/BBB ubuntu bash
so that the AAA folder in the root directory of the host is mapped to the container Ubuntu, and can be shared between the two;
5. Log in to the ubuntu mirroring system in docker :
docker run -ti ubuntu /bin/bash
#6866 is the first four digits of the IMAGE ID - you can distinguish which image it is
6. Exit and then enter ubuntu
1. First use docker ps -a to find the corresponding number of the CONTAINER ID (for example: 0a3309a3b29e)
2. Enter the system docker attach 0a3309a3b29e (there is no response at this time, ctrl+c will enter the ubuntu system went)
PS: The command I run
docker run -it -v /download:/download -p 53:53 ubuntu bash
Additional common commands:
1. Check the ubuntu version: cat /etc/issue
2. Modify the ubuntu mirror source to ubuntu:
1. Backup cp /etc/apt/sources.list /etc/apt/sources.list.backup
2. Clear the content and add the following content vi /etc/apt/sources.list

3、更新生效：apt-get update
3. Install and enable ssh to run user remote login
1. Install the sshd command: apt-get install openssh-server openssh-client
2. Edit /etc/ssh/sshd_config , comment out: PermitRootLogin without-password, increase PermitRootLogin yes
3. Start the command
service ssh start
service ssh stop
service ssh restart
