一、 背景：
- 1、服务器版本： CentOS Linux release 7.4.1708 (Core)
- 2、数据库版本： 5.7.22
- 3、目的：
- 安装mysql5.7.22
- 使用mysql3306 可以登录
二、安装
法1：docker安装
从2017年3月开始，docker版本变化：
| 项目 | 说明 |
|---|---|
| 版本格式 | YY.MM |
| stable版本 | 每个季度发行 |
| edge版本 | 每个月发行 |
| CE社区版 | |
| EE企业版 |
步骤：
#删除系统自带的Docker及依赖
yum remove docker* container-selinux docker-engine
#添加必要的依赖
yum install -y yum-utils device-mapper-persistent-data lvm2
#添加软件源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# 更新并安装 Docker-CE
yum makecache fast
yum install -y docker-ce
#开启Docker服务
systemctl start docker
法2： 实体机安装
步骤：
1、有网环境准备好安装包：
