docker.io/library/mysql:5.7 五、创建mysql容器1.创建数据目录[root@node ~]# mkdir -p /data/mysql
[root@node ~]# cd /data/mysql/
[root@node mysql]# ls 2.运行mysql容器[root@node mysql]# docker run -d --name mysql_01 --restart always -v /data/mysql/db:/var/lib/mysql -p 3541:3306 -e MYSQL_ROOT_PASSWORD=admin -e MYSQL_DATABASE=data mysql:5.7

引言：Docker 的出现，让我们的部署工作变得更加轻松，而 MySQL 数据库是我们常用的数据库之一。那么如何使用 Docker 部署 MySQL 数据库呢？本文将为您一一解答，包括安装 Docker、拉取 MySQL 镜像、创建容器、配置 MySQL 数据库等全方位攻略。
第一步：安装 Docker
首先，我们需要安装 Docker。请到官网（https://www.docker.com/）下载适合您的系统版本。安装完毕后，可以在 Terminal（Windows 用户请使用 PowerShell）中使用以下命令检查 Docker 版本：
docker version
如果检测到版本号，则说明 Docker 安装成功。
第二步：拉取 MySQL 镜像
接下来，我们需要拉取 MySQL 镜像。打开 Terminal（Windows 用户请使用 PowerShell），输入以下命令：
docker pull mysql:tag
其中 tag 为相应的版本号，例如 5.7、8.0 等。拉取完成后，在 Terminal 中输入以下命令，查看是否拉取成功：
docker images
如果拉取成功，则可以看到类似于以下信息：
REPOSITORY TAG IMAGE ID CREATED SIZE
mysql 8.0 8e1e2467f3f1 2 weeks ago 544MB
第三步：创建容器
接下来，我们需要创建容器并启动 MySQL。请使用以下命令：
docker run -p 3306:3306 --name mysql_server -e MYSQL_ROOT_PASSWORD=yourpassword -d mysql:tag
其中：
-p 3306:3306：将容器的 3306 端口映射到主机的 3306 端口。
--name mysql_server：设置容器名称为 mysql_server。
-e MYSQL_ROOT_PASSWORD=yourpassword：设置 MySQL 的 root 密码为 yourpassword。
-d：后台运行容器。
MySQL 容器将在后台运行，可以使用以下命令查看是否启动成功：
docker ps
如果启动成功，则可以看到类似于以下信息：
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
bc7ac57ad8cc mysql:tag \"docker-entrypoint.s…\" 4 minutes ago Up 4 minutes 0.0.0.0:3306->3306/tcp, 33060/tcp mysql_server
第四步：配置 MySQL 数据库
接下来，我们需要在 MySQL 中创建相应的数据库。使用以下命令打开 MySQL：
docker exec -it mysql_server mysql -uroot -p
其中，mysql_server 为容器名称。
输入设置的 root 密码 yourpassword 后，即可进入 MySQL。
在 MySQL 中，我们可以使用以下命令创建数据库：
create database dbname;
其中，dbname 为数据库的名称。
除此之外，我们还需创建用户并授权：
CREATE USER 'username' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON dbname.* TO 'username'@'%';
其中，username 为我们创建的用户名，password 为密码，dbname.* 表示我们授权该用户对 dbname 数据库下的所有表执行所有操作。
第五步：备份和还原数据
在使用 MySQL 进行项目开发的时候，我们需要对数据进行备份，以防止数据丢失。使用以下命令备份 MySQL 数据库：
docker exec mysql_container_name /usr/bin/mysqldump -u root --password=root_password database_name > backup.sql
其中，mysql_container_name 为 MySQL 容器名称，root_password 为 MySQL 的 root 密码，database_name 为要备份的数据库名称。
使用以下命令还原 MySQL 数据库：
docker exec -i mysql_container_name /usr/bin/mysql -u root --password=root_password database_name < backup.sql
其中，mysql_container_name 为 MySQL 容器名称，root_password 为 MySQL 的 root 密码，database_name 为要恢复的数据库名称。
第六步：关闭容器
在项目部署完成后，我们需要关闭 MySQL 容器。使用以下命令：
docker stop mysql_container_name
其中，mysql_container_name 为 MySQL 容器名称。
第七步：启动容器
需要重新启动 MySQL 容器时，请使用以下命令：
docker start mysql_container_name
其中，mysql_container_name 为 MySQL 容器名称。
结语：通过 Docker 部署 MySQL 数据库，可以大大简化我们的部署流程，也可以在数据备份和恢复时更加便捷。本文基于 Docker 19.03.8 和 MySQL 8.0.21 版本进行编写，部分操作可能因版本不同而有所差异，请以实际为准。
