Docker 安装 mysql
方法一、docker pull mysql
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
[email protected]:~/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。
[email protected]:~/mysql$ docker images |grep mysql mysql 5.6 2c0964ec182a 3 weeks ago 329 MB
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。
[email protected]:~$ 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
[email protected]:~/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
[email protected]:~/mysql$ docker images |grep mysql mysql 5.6 2c0964ec182a 3 weeks ago 329 MB
使用mysql镜像
运行容器
[email protected]:~/mysql$ docker run -p 3306:3306 --name mymysql -v $PWD/conf:/etc/mysql/conf.d -v $PWD/logs:/logs -v $PWD/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.621cb892[email protected]runoob:~/mysql$
命令说明:
-p 3306:3306:将容器的 3306 端口映射到主机的 3306 端口。
-v -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 $PWD/data:/var/lib/mysql :将主机当前目录下的data目录挂载到容器的 /var/lib/mysql 。
-e MYSQL_ROOT_PASSWORD=123456:初始化 root 用户的密码。
查看容器启动情况
[email protected]:~/mysql$ docker ps CONTAINER ID IMAGE COMMAND ... PORTS NAMES21cb89213c93 mysql:5.6 "docker-entrypoint.sh" ... 0.0.0.0:3306->3306/tcp mymysql

最新官方MySQL(5.7.19)的docker镜像在创建时映射的配置文件目录有所不同,在此记录并分享给大家:
官方原文:
The MySQL startup configuration is specified in the file
/etc/mysql/my.cnf
, and that file in turn includes any files found in the/etc/mysql/conf.d
directory that end with.cnf
. Settings in files in this directory will augment and/or override settings in/etc/mysql/my.cnf
. If you want to use a customized MySQL configuration, you can create your alternative configuration file in a directory on the host machine and then mount that directory location as/etc/mysql/conf.d
inside themysql
container.大概意思是说:
MySQL(5.7.19)的默认配置文件是 /etc/mysql/my.cnf 文件。如果想要自定义配置,建议向 /etc/mysql/conf.d 目录中创建 .cnf 文件。新建的文件可以任意起名,只要保证后缀名是 cnf 即可。新建的文件中的配置项可以覆盖 /etc/mysql/my.cnf 中的配置项。
具体操作:
首先需要创建将要映射到容器中的目录以及.cnf文件,然后再创建容器
