### 【Mysql】通过 docker 快速搭建 mysql 环境 ###

#### 1、方式一:查找Docker Hub上的mysql镜像 ####

##### 获取镜像 #####

docker pull mysql:5.6

##### 创建目录 #####

mkdir mysql

##### 获取配置文件 #####

#进入创建的目录里面
    cd mysql
    #启动一个测试类从中获取配置文件
    docker run -p 3307:3306 --name mymysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6
    #复制配置文件
    docker cp mymysql:/etc/mysql .
    mv mysql/ conf
    #复制日志文件
    docker cp mymysql:/var/log/mysql .
    mv mysql logs
    #复制data
    docker cp mymysql:/var/lib/mysql  .
    mv mysql/ data
    #删除容器
    docker rm -f mymysql

##### 启动容器 #####

docker run \
    -p 3307:3306 \
    --name mysql \
    --privileged=true \
    --restart=always \
    -v $PWD/conf:/etc/mysql/conf.d \
    -v $PWD/logs:/var/log/mysql \
    -v $PWD/data:/var/lib/mysql \
    -e MYSQL_ROOT_PASSWORD=123456 \
    -d \
    mysql:5.6

**注意:MYSQL\_ROOT\_PASSWORD是root账户的登录密码,$PWD 为创建mysql的绝对路径**

#### 2、方式二:通过 Dockerfile构建 ####

##### 在mysql目录下创建Dockerfile文件 #####
