Install Virtual Machine

• Install Virtual Machine
  docker-machine create --engine-registry-mirror=https://nm7he5wc.mirror.aliyuncs.com -d virtualbox zdy

• View information
  docker info

• Set up shared folders
  Open virtualbox
  Click on the settings of virtual machine zdy
  Click on the shared folder
  Click +
  Add fixed or temporary distribution directory

• Add a bridge card
  Click network-network card 3, change to network bridge, modify to allow all

• Login with putty tool
  Log in with username = docker password = tcuser
  After logging in, use sudo -i or sudo su to go to the root user

Install mysql

• Download mysql image
  docker pull mysql:latest
  docker pull mysql choose the name with the highest start to download

• View mirror
  docker images

• Run the container

  • Writing 1
    docker run --name dockermysql -p 3307:3306 -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql

    --name Set an alias for the mysql instance. -p 3307 is the externally exposed port. 3306 is the internal port 
     -e MYSQL_ROOT_PASSWORD Set the mysql login password -d Run as a daemon (run in the background) The last mysql is the mirror name 
    

  • Writing 2
    docker run -itd --name mysql1 -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 mysql

  • Writing 3
    docker run -itd --name mysql1 -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -v /d/volume/mysql:/var/lib/mysql mysql
    -v /d/volume/mysql:/var/lib/mysql means to mount the d drive/volume/mysql folder to the /var/lib/mysql path

• Install mariadb (sister version of mysql)
  docker run -p 3306:3306 -v /home/data/mariadb:/var/lib/mysql:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root --name mariadb -d mariadb:latest
  -v /zdy/mysql:/var/lib/mysql `
  The colon is in front of the host directory, followed by the path in the docker container.

  I tested it by sharing the window directory to the host, and then mounting to a certain path, unable to create a container
  It just throws an exception after creating some files
  docker logs mariadb just mentioned that when creating the database file, the binary file is in error. It is suspected that the ntfs and linux file formats are different.

• View running container
  docker ps

• Into the container
  docker exec -it mysql1 /bin/bash

• Login mysql
  mysql -uroot -p123456

• Authorize
  grant all privileges on . to ‘root’@’%’ ;
  flush privileges;

• Host connection mysql in docker
  You can check ifip in ifconfig, usually beginning with 192.168.99
  ip=192.168.99.*

• Upgrading from 5.7 to 8.0 will not change the authentication method of existing users, but new users will use the new caching_sha2_password by default.

The client does not support the new encryption method.
One of the methods, modify the user's password and encryption method
ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘password’;
New features of mysql8.* caching_sha2_password password encryption method
The previous version of mysql password encryption used mysql_native_password
The newly added user password uses caching_sha2_password by default
If you upgrade based on the previous mysql, the password encryption used by the user is mysql_native_password
If the previous password encryption method is used, modify the file /etc/my.cnf

• Database time zone issues:
  There is a problem with serverTimezone=UTC parameter when linking to the database
  Just change to serverTimezone=Asia/Shanghai!

• If you need to access the container in boot2docker outside the virtualbox

  The port mapping of the virtualbox virtual host needs to be enabled for external programs to connect to the database in docker
  Select the virtual host-settings-network-network card (NAT is usually network card 1)-advanced-port forwarding-port forwarding rules (pop-up window) + settings

Install redis

	docker search  redis 
	docker pull redis:latest 
	docker run --name redis  -d -p 6379:6379 redis
	docker ps
	docker exec -it redis /bin/bash

Install tomcat

	docker pull tomcat:latest 
	docker run --name tomcat -p 8080:8080 -v $PWD/test:/usr/local/tomcat/webapps/test -d tomcat  	
	docker exec -it tomcat /bin/bash

Install ngnix

	docker pull nginx:latest
	docker run --name nginx-test -p 8080:80 -d nginx

–Name nginx-test: container name.
-p 8080:80: Port mapping, mapping the local 8080 port to the 80 port inside the container.
-d nginx: Set the container to always run in the background.

Export container

cd the path to export
 docker export container name|container id> backup file name.tar	

docker export mariadb > my_mariadb.tar

Import container backup into image, install image

cat file name.tar | docker import-image_name:tag
cat my_mariadb.tar |docker import - mymariadb:0.0.1

• View imported images with docker images
  Run after importing, the original operating parameters must be brought, otherwise it will not work normally,
  and be sure to add the content of the command part (query via docker ps --no-trunc)
  For example:
  The following cannot be executed successfully
  docker run --name mymariadb1 -d mymariadb:0.0.1 docker-entrypoint.sh - mysqld
  The following can be started, but the host cannot connect to 3306
  docker run -v /home/data/mariadb:/var/lib/mysql --name mymariadb -d mymariadb:0.0.1 docker-entrypoint.sh mysqld
  The following can be executed successfully
  docker run -p 3306:3306 -v /home/data/mariadb:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root --name mymariadb -d mymariadb:0.0.1 docker-entrypoint.sh mysqld
