本文主要記錄基于docker環(huán)境搭建mysql服務(wù)器的過(guò)程，由于我的服務(wù)器上幾個(gè)月前就已經(jīng)安裝過(guò)docker，本文不再講解如何安裝docker。
更新docker
由于之前安裝的docker版本是1.12.6，現(xiàn)在是17+，簡(jiǎn)單做了個(gè)升級(jí)，可以參考CentOS7升級(jí)最新版本Docker

執(zhí)行docker run --rm -i -t -v /data/mysql/master/conf:/home/test mysql /bin/bash，
再執(zhí)行cp /etc/mysql/my.cnf /home/test將mysql配置文件copy一份到本地后exit退出，
如果不復(fù)制此配置文件，后面啟動(dòng)容器時(shí)掛載此配置文件將會(huì)報(bào)錯(cuò)，提示my.cnf不是一個(gè)文件夾。
啟動(dòng)mysql
# cd /data/mysql/master
# docker run -p 127.0.0.1:3306:3306 --restart=always --name mysqlmaster -v $PWD/conf/my.cnf:/etc/mysql/my.cnf -v $PWD/logs:/logs -v $PWD/data:/mysql_data -e MYSQL_ROOT_PASSWORD=123456 -d mysql

最后嘗試登陸mysql，啟動(dòng)并登陸成功。
