Preface

Recently, the computer is often turned off for a long time, and it is always necessary to press the power button for a long time and force it off. I don't know what happened.

Later, when I checked the log when shutting down the phone, I found that mysql could not be stopped. This is annoying! What shall I do? I searched the Internet and didn't find any good solution. You can't press the power button every time you turn it off, can you? The computer is so expensive, and it's my own computer. What if it breaks down?

Delete the mysql? As a code writer, you have to install mysql in the computer. You have to use it every day. In a virtual machine? This seems to work. Whether you can turn off the mysql or not, I'll just shut down the virtual machine. Then I looked at the virtualbox, which had not been opened on my computer for more than a year, and thought that it was not appropriate to dress here. My computer hard disk is 250g, in order to install a mysql, but also to give it a dozen gigabytes of hard disk, and then give it 2G of memory, is not appropriate. What are we going to do? Buckle my mouse, think of the previous year to follow the trend of the study of docker, um, you.

Start installing mysql into docker

Install docker

I can't remember the order of docker. I searched the Internet for the installation command. Is it still very simple? It will be fine as soon as the order is knocked and brushed. (deepin system installed on my computer)

Wget-qO- https://get.docker.com/ | sh

Then you need to start it up, which is also a command.

Sudo service docker start

Docker runs Ubuntu

Docker is installed, how to run a system inside? Only docker can't run mysql! At this point, you need to download a system image, which is the image of Ubuntu. First of all, you need to search for any images that can be searched for in the market with the following command.

/ / Command sudo docker search ubuntu// result NAME DESCRIPTION STARS OFFICIAL AUTOMATEDubuntu Ubuntu is a Debian-based Linux operating sys... 9583 [OK] dorowu/ubuntu-desktop-lxde-vnc Docker image to provide HTML5 VNC interface...

A bunch of images have been found here. Let's choose the one that ranks first.

Now you need to download this image, using the following command:

The sudo docker pull ubuntu:18.04// colon is followed by the version number. If you don't know, you can only check it on the Internet. If you don't write it, you can download the latest one.

But. It is said on the Internet that due to some force majeure, the domestic download image is very slow, so it is necessary to add a mirror image. You need to add a file under the path of / etc/docker: daemon.json, which contains the image address:

{"registry-mirrors": ["http://hub-mirror.c.163.com"]}"

And then restart. Then execute the command above to download the image, then drink some coffee and wait for a while.

After downloading, let's take a look at the images on the computer and use the following command:

Sudo docker images / / result REPOSITORY TAG IMAGE ID CREATED SIZEubuntu 18.04 7698f282e524 2 weeks ago 69.9MB

Here you can see that there is already an image of Ubuntu version 18.04. Now we need to activate this image.

/ command sudo docker run-it-d ubuntu:18.04 / bin/bash// explain run: create a new container and run a command-it: run the container in interactive mode and reassign a pseudo-input terminal, on behalf of-I-t--name ubuntu18: specify a name for the container-d: background run container ubuntu:18.04: image name / bin/bash: run the program in the image If not, the mirror image will just stop.

Now the mirror image is started successfully, but I have to log in. At this point, you need to see which containers are running and execute:

/ / Command sudo docker ps-a minutes ago Up / explain ps: list containers-a: show all containers, including / / result CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES1ce6fa95862c ubuntu:18.04 "/ bin/bash" 6 minutes ago Up 6 minutes brave_mendeleev

Here we can see that there is a container in which NAME is brave_mendeleev. Now let's go into this container. Execute the following command

/ / Command sudo docker exec-it brave_mendeleev / bin/bash// explain brave_mendeleev: container name exec: execute command / / result hjx@hjx-PC:/etc/docker$ sudo docker exec-it brave_mendeleev / bin/bashroot@1ce6fa95862c:/# in the running container

In this way, we successfully logged in to the container whose image is the ubuntu18.04 version. Now we can install mysql in it.

Install mysql in the ubuntu container

Install mysql I like to install it directly with apt. I'll type it directly here:

Apt install mysql-server-5.7

Later, it is found that it can also be successfully installed in the container. After the installation is successful, we need to bind the mysql port in the container to port 3306 of our host. The steps here are:

1: stop the container (or not)

/ / stop container sudo docker stop brave_mendeleev// explain stop: container life cycle management command, which consists of the following commands: start: start the container stop: stop the container restart: restart the container

2: submit the container with mysql installed as a new image

/ / Command sudo docker commit brave_mendeleev ub/mysql// explain commit: create a new image from the container ub/mysql: new image name

3: bind the port and start a new mirror

Uh... The game here is dead. It didn't work out. / (please) / ~ ~

I decided to bind port 3306 when I started ubuntu mirroring, and then perform the above operation again.

After a long operation. After deleting the original container, rebinding port 3306 to start, logging in to the container, and installing mysql, it installed and ran successfully.

A simpler way

Well, just search for the image mysql directly and start it. It's so simple, 😂😂😂😂.

/ / download mysql5.7 image sudo docker pull mysql:5.7// binding port 3306 launch sudo docker run-p 3306 MYSQL_ROOT_PASSWORD=123456-d mysql:5.7// interpretation-e MYSQL_ROOT_PASSWORD=123456: initialize the password of the root user

After that, there are a bunch of other parameters, which I don't need here, so I won't write them.
