三、安装Docker、docker-compse

1、docker安装

docker安装命令汇总

# sudo yum update -y
# sudo yum install -y docker
# systemctl start docker
# systemctl enable docker
# systemctl status docker
# docker version
  • docker版本查询
[root@hcss-ecs-2d95 ~]# docker version
Client:
 Version:         1.13.1
 API version:     1.26
 Package version: docker-1.13.1-209.git7d71120.el7.centos.x86_64
 Go version:      go1.10.3
 Git commit:      7d71120/1.13.1
 Built:           Wed Mar  2 15:25:43 2022
 OS/Arch:         linux/amd64

Server:
 Version:         1.13.1
 API version:     1.26 (minimum version 1.12)
 Package version: docker-1.13.1-209.git7d71120.el7.centos.x86_64
 Go version:      go1.10.3

 Experimental:    false
[root@hcss-ecs-2d95 ~]# docker-compose version
Docker Compose version v2.20.3

2、docker-compose安装

# 下载插件
sudo curl -L "https://github.com/docker/compose/releases/download/2.20.3/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

PS:若直接在云服务器中下载受阻，可以先将软件包下载到本地后，再上传到云服务器中。

# 授权
sudo chmod +x /usr/local/bin/docker-compose

# 查看docker-compose版本
docker-compose version

四、方法① 使用Docker安装部署MySQL服务

# 拉取mysql镜像
sudo docker pull mysql:5.7.33

# 查看拉取的镜像
sudo docker image ls

# 启动MySQL服务
sudo docker run -it --rm --name xybdb -e MYSQL_ROOT_PASSWORD=12345678 -d mysql:5.7.33

# 进入容器bash-shell
sudo docker exec -it xybdb bash -p

# 查看容器内目录结构
ls -al
# drwxr-xr-x   2 root root    6 Apr 10  2021 docker-entrypoint-initdb.d

# 在shell中连接数据库
mysql -u root -p -h 127.0.0.1

# 显示当前数据库
mysql> show databases;

# 停止xybdb容器
sudo docker container stop xybdb

# 查看是否删除
sudo docker container ls -a

具体操作过程演示：

拉取mysql镜像动画演示

image-20230917101429891

使用`docker pull命令`拉取mysql镜像

五、方法② 使用docker-compse安装部署MySQL服务（可选）

## 编辑文件目录
# 创建mysql目录
[root@hcss-ecs-2d95 ~]# mkdir mysql

# 数据库初始化脚本目录
[root@hcss-ecs-2d95 ~]# mkdir mysql/initdb

# 数据库数据存储目录
[root@hcss-ecs-2d95 ~]# mkdir mysql/datadir

# 创建docker-compose.yml
version: "3"
services: 
  mysql:
    restart: always
    image: mysql:5.7.33	# 指定Docker镜像名
    ports:
      - 3306:3306
    container_name: xyb_mysql-server
    volumes:
      - ./mysql/initdb:/initdb:/docker-entrypoint-initdb.d  # 启动初期数据绑定位置
      - ./mysql/datadir:/var/lib/mysql					    # 数据库数据存储位置指定
    environment:
      - MYSQL_ROOT_PASSWORD=12345678		# 设定数据库root用户名密码

# 编译服务
[root@hcss-ecs-2d95 ~]# docker-compose build

# 容器启动
[root@hcss-ecs-2d95 ~]# docker-compose up -d

# 查询容器状态
[root@hcss-ecs-2d95 ~]# docker-compose ps
[root@hcss-ecs-2d95 ~]# nmap 127.0.0.1

Starting Nmap 6.40 ( http://nmap.org ) at 2023-09-17 15:11 CST
Nmap scan report for localhost (127.0.0.1)
Host is up (0.0000040s latency).

22/tcp   open  ssh
25/tcp   open  smtp
3306/tcp open  mysql

Nmap done: 1 IP address (1 host up) scanned in 1.59 seconds

# 连接mysql client
[root@hcss-ecs-2d95 ~]# docker exec -it xyb_mysql-server -p

# 执行myweb容器内的命令
[root@hcss-ecs-2d95 ~]# docker-compose run mysql ls

# 查看容器输出日志
[root@hcss-ecs-2d95 ~]# docker-compose logs -f mysql

# 容器停止
[root@hcss-ecs-2d95 ~]# docker-compose stop

# 容器停止+容器删除（容器+网络）
[root@hcss-ecs-2d95 ~]# docker-compose down

# 容器停止+消除（容器+网络+镜像）
[root@hcss-ecs-2d95 ~]# docker-compose down --rmi all

# 查看docker-compose服务
[root@hcss-ecs-2d95 ~]# docker-compose ps

具体操作演示步骤如下：

[root@hcss-ecs-2d95 ~]# docker-compose up -d
[+] Running 2/2
 ✔ Network root_default        Created                         0.0s

六、连接MySQL—phpMyAdmin管理工具

  • 编辑docker-compose.yml配置文件
version: '3'
services: 
  phpmyadmin: 
    image: phpmyadmin:latest
    container_name: web_phpmyadmin
    ports: 
      - 80:80
    environment: 
      - PMA_HOST=121.37.153.196
      - PMA_USER=root
      - PMA_PASSWORD=12345678
  • 启动phpmyAdmin管理工具
[root@hcss-ecs-2d95 ~]# docker-compose build

[root@hcss-ecs-2d95 ~]# docker-compose up -d

[root@hcss-ecs-2d95 ~]# docker-compose ps
NAME                IMAGE               COMMAND                  SERVICE             CREATED             STATUS
     PORTS
web_phpmyadmin      phpmyadmin:latest   "/docker-entrypoint.…"   phpmyadmin          14 seconds ago      Up 12 seconds       0.0.0.0:80->80/tcp
xyb_mysql-server    mysql:5.7.33        "docker-entrypoint.s…"   mysql               14 minutes ago      Up 14 minutes       0.0.0.0:3306->3306/tcp, 33060/tcp

具体操作演示如下：
