Quickly build the following environment:

VirtualBox

VM environment

docker

Virtual container

Common docker commands
In addition:
Docker container restart strategy:docker inspect 容器ID

Delete old version

sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

Installation: Official website tutorial https://docs.docker.com/engine/install/centos/ (not recommended)

# 推荐
$ sudo yum install docker

Open

$ sudo systemctl start docker
$ sudo systemctl enable docker

Alibaba Cloud Container Image Service: https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors

$ sudo mkdir -p /etc/docker
$ sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://eslh5xx9.mirror.aliyuncs.com"]
}
EOF
$ sudo systemctl daemon-reload
$ sudo systemctl restart docker

MySQL

Start mysql

Exception handling: error creating overlay mount to / var / lib / docker / overlay2

$ sudo docker pull mysql:5.7
$ sudo docker images 

$ sudo docker run --name mysql --privileged=true -p 3307:3306 \
-v /dev/mydata/mysql/log:/var/log/mysql \
-v /dev/mydata/mysql/data:/var/lib/mysql \
-v /dev/mydata/mysql/conf:/etc/mysql \
-e MYSQL_ROOT_PASSWORD=root \
-d mysql:5.7 

• -v File directory (volume) mapping
• /dev/mydata/mysql/log:/var/log/mysql Log mapped to local
• /dev/mydata/mysql/data:/var/lib/mysql Database data is mapped to local
• /dev/mydata/mysql/conf:/etc/mysql Configuration file mapped to local
• MYSQL_ROOT_PASSWORD=root (Required) Set database password

Enter mysql

docker exec -it mysql /bin/bash

Docker official website about MySQL: 5.7: https://hub.docker.com/_/mysql
Docker official website about MySQL: 5.7 Dockerfile: https://github.com/docker-library/mysql/blob/d284e15821ac64b6eda1b146775bf4b6f4844077/5.7/Dockerfile

Modify encoding

vim  /dev/mydata/mysql/conf/my.cnf

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

[mysqld]
init_connect='SET collation_connection=utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake
skip-name-resolve

Restart mysql and enter

 docker restart mysql
 docker exec -it mysql /bin/bash

Start with docker start and start

$ sudo docker update mysql --restart=always

docker update: update the configuration of one or more containers

repeat

installation

$ sudo docker pull redis

Turn on data persistence

vim /dev/mydata/redis/conf/redis.conf

Input configuration

# 启用AOF持久化
appendonly yes

start up

$ sudo docker run --name redis \
-v /dev/mydata/redis/data:/data \
-v /dev/mydata/redis/conf:/etc/redis \
-p 6379:6379  \
-d redis redis-server /etc/redis/redis.conf
$  

Note: The path mapping here cannot be a file, because it will be overwritten as a directory, and an error will be reported when starting again

Start with docker start and start

$ sudo docker update redis --restart=always

Client login

docker exec -it redis redis-cli

docker restart redis
