1	runoob@runoob:~/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。

方法二、通过 Dockerfile构建

创建Dockerfile

首先，创建目录mysql,用于存放后面的相关东西。

[Bash shell] 纯文本查看 复制代码

?

1	runoob@runoob:~$ 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

runoob@runoob:~/mysql$ docker run -p 3306:3306 --name mymysql -v $PWD/conf:/etc/mysql/conf.d -v $PWD/logs:/logs -v $PWD/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6 21cb89213c93d805c5bacf1028a0da7b5c5852761ba81327e6b99bb3ea89930e runoob@runoob:~/mysql$

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:/etc/mysql/conf.d：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:/var/lib/mysql ：将主机当前目录下的data目录挂载到容器的 /var/lib/mysql 。
• -e MYSQL_ROOT_PASSWORD=123456：初始化 root 用户的密码。
