目录

🍁通过 Dockerfile 构建

• 创建Dockerfile
• 创建目录mysql，用于存放后面的相关东西

mkdir -p ~/mysql/data ~/mysql/logs ~/mysql/conf

- data目录将映射为mysql容器配置的数据文件存放路径
- logs目录将映射为mysql容器的日志目录
- conf目录里的配置文件将映射为mysql容器的配置文件

• 进入创建的mysql目录，创建Dockerfile

• 通过Dockerfile创建一个镜像，替换成自己的名字

docker build -t mysql .

• 创建完成后，可在本地镜像列表中查找到刚刚创建的镜像

docker images |grep mysql

🍁docker pull mysql

• 查找Docker Hub上的mysql镜像

docker search mysql

• 拉取官方的镜像，标签为5.6

docker pull mysql:5.6

• 等待下载完成后就可以在本地镜像列表里查到REPOSITORY为mysql,标签为5.6的镜像。

🍁使用mysql镜像

• 运行容器

docker run -p 3306:3306 --name mymysql -v $PWD/conf/my.cnf:/etc/mysql/my.cnf -v $PWD/logs:/logs -v $PWD/data:/mysql_data -e MYSQL_ROOT_PASSWORD=123456 -d 

• 命令说明： - -p 3306:3306：将容器的3306端口映射到主机的3306端口- -v $PWD/conf/my.cnf:/etc/mysql/my.cnf：将主机当前目录下的conf/my.cnf挂载到容器的/etc/mysql/my.cnf- -v $PWD/logs:/logs：将主机当前目录下的logs目录挂载到容器的/logs- -v $PWD/data:/mysql_data：将主机当前目录下的data目录挂载到容器的/mysql_data- -e MYSQL_ROOT_PASSWORD=123456：初始化root用户的密码
• 查看容器启动情况
