Docker 安装 MySQL

 

# add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added

RUN groupadd -r mysql useradd -r -g mysql mysql  

# add gosu for easy step-down from root

通过Dockerfile创建一个镜像，替换成你自己的名字

runoob@runoob:~/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

runoob@runoob:~/mysql$ docker images |grep mysql

mysql 5.6 2c0964ec182a 3 weeks ago 329 MB

方法二、docker pull mysql

查找Docker Hub上的mysql镜像

runoob@runoob:/mysql$ docker search mysql

这里我们拉取官方的镜像,标签为5.6

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。

使用mysql镜像

运行容器

runoob@runoob:~/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

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/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
