docker封装mysql镜像

# 一、概述 #

直接使用官方的镜像

docker pull mysql:5.7

但是mysqld.cnf并没有优化，还是默认的。

# 二、封装镜像 #

创建目录

# dockerfile目录
    mkdir -p /opt/dockerfile/mysql
    # 持久化目录
    mkdir -p /data/mysql/data

/opt/dockerfile/mysql 目录结构如下：

./
    ├── dockerfile
    ├── mysqld.cnf
    └── run.sh

## dockerfile ##

FROM mysql:5.7
    ADD mysqld.cnf /etc/mysql/mysql.conf.d/mysqld.cnf

## mysqld.cnf ##
