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

dockerfileFROM mysql:5.7

ADD mysqld.cnf /etc/mysql/mysql.conf.d/mysqld.cnf

mysqld.cnf[client]

socket = /var/run/mysqld/mysqld.sock

[mysql]
