创建Dockerfile
首先,创建目录mysql,用于存放后面的相关东西。
root@localhost:~$ 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,替换成你自己的名字
root@localhost:~/mysql$ docker build -t mysql .
创建完成后,我们可以在本地的镜像列表里查找到刚刚创建的镜像
root@localhost:~/mysql$ docker images |grep mysql mysql 5.6 2c0964ec182a 3 weeks ago 329 MB
查找Docker Hub上的mysql镜像

这里我们拉取官方的镜像,标签为5.6
root@localhost:~/mysql$ docker pull mysql:5.6
等待下载完成后,我们就可以在本地镜像列表里查到REPOSITORY为mysql,标签为5.6的镜像。
root@localhost:~/mysql$ docker run -p 3306:3306 --name mymysql -v $PWD/conf/my.cnf:/etc/mysql/my.cnf -v $PWD/logs:/logs -v $PWD/data:/mysql_data -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6 21cb89213c93d805c5bacf1028a0da7b5c5852761ba81327e6b99bb3ea89930e root@localhost:~/mysql$
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
