# 1、应用场景 #

可以将生产环境的数据库数据导到测试环境。

# 2、安装mysql #

## 2.1 查找mysql镜像 ##

## 2.2 拉取mysql5.7镜像 ##

>docker pull mysql:5.7

## 2.3 查看本地镜像列表 ##

>docker images |grep mysql
    docker.io/mysql                                          5.7                 ee7cbd482336        10 days ago         372.1 MB

# 3、启动mysql #

>docker run -p 13306:3306 --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:5.7

*  \-p 13306:3306：将容器的 3306 端口映射到主机的 13306 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。

$PWD/data中会存入数据库中的数据。

# 4、数据复制到测试环境 #

将第3步中的data文件夹复制到测试服务器，在当前目录启动mysql。

>docker run -p 13306:3306 --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:5.7

# 5、其他 #

## 5.1 停止mysql ##

>docker ps #查询容器id
    86e4f747393d        mymysql:5.7.3                              "docker-entrypoint.sh"   32 minutes ago      Up 32 minutes       33060/tcp, 0.0.0.0:13306->3306/tcp   mymysql
    >docker stop 86e4f747393d #停止
    >docker rm 86e4f747393d #删除
    >docker run -p 13306:3306 --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:5.7 #启动

# 5.2 删除镜像 #

>docker images #查找本地镜像
    mymysql                                                  5.7.1               5858ac4f6191        About an hour ago   372.1 MB
    >docker rmi 5858ac4f6191 #删除镜像

**注意：**先删除容器，才能删除镜像。
