Docker安装MySQL8.0

本文中记录的是利用Docker安装MySQL8.0。因为工作经常要使用SQL，学习的MySQL5.7的语法已经不能完全满足需求，必须要x学习下最新的MySQL8.0，因为它有很多最近的函数和方法其老版本没有的，所以利用Docker安装了一个用来学习该版本的语法。

安装过程

首先需要下载和启动Docker，自行解决

查看Docker命令

拉取mysql镜像

docker ps   # 查看镜像
docker pull mysql:8.0   # 拉取指定的MySQL版本8.0
docker pull mysql   # 默认拉取最新mysql版本，肯定是8.0
docker search mysql   # 搜索mysql相关的镜像

查看mysql镜像

第一次启动

docker run -p 3308:3306 --name Peter  -e MYSQL_ROOT_PASSWORD=yourpassword -d mysql:latest

解释下这条命令的参数：

-p 3308:3306：将容器内服务端口3306映射到本机的3308端口（本机端口:容器服务端口）
--name Peter：给容器取名字
-e MYSQL_ROOT_PASSWORD=yourpassword：docker的MySQL默认的root密码是随机的，改一下默认的root用户密码yourpassword
-d mysql:latest：在后台运行mysql:latest镜像产生的容器

docker run -p 本地主机端口号:容器服务端口号 --name 容器名字 [-e 配置信息修改] -d 镜像名字

之后的启动MySQL：docker start Peter

解决连接报错-修改密码

MySQL8.0之后更改了密码的加密规则，只要在命令窗口把加密方法改回去

进入mysql容器

docker exec -it Peter bash   # 1、进入创建的镜像
mysql —uroot -p   # 2、登陆MySQL，需要输入自己设置的密码

修改密码

alter user 'root'@'%' identified by 'your_password' password expire never;
alter user 'root'@'%' identified with mysql_native_password by 'your_password';
flush privileges;   -- 刷新权限
