在docker上安装mysql有两种方式
1.通过Dockerfile构建
2.直接在docker hub上拉取镜像安装
=================本篇采用方法2=====================
1.搜索查找docker hub上的mysql镜像
docker search mysql
2.拉取官方镜像 标签为5.7，在此之前，先创建一个mysql目录，在目录中拉取
问题：在拉取过程中会出现龟速的问题
解决问题的方法：https://www.cnblogs.com/sxdcgaq8080/p/9198748.html
下载完成之后
3.下载完成之后，可以通过命令查看本地现有的所有镜像
docker images
也可以通过命令，通过Image ID查看具体某个镜像的详细信息
docker inspect 0d16d0a97dd1
4.运行docker镜像，即创建并实例化了一个容器
docker run -p 33060:3306 --name mysql4SXD -v $PWD/conf:/etc/mysql/conf.d -v $PWD/logs:/logs -v $PWD/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=398023 -d mysql:5.7
命令说明：
-
-p 33060:3306：将容器的 3306 端口映射到主机的 33060 端口。
- --name mysql4SXD ： 给实例化本镜像生成的容器起个名字
-
-v -v $PWD/conf:/etc/mysql/conf.d：将主机当前目录下的 conf/my.cnf 挂载到容器的 /etc/mysql/my.cnf。
-
-v $PWD/logs:/logs：将主机当前目录下的 logs 目录挂载到容器的 /logs。
-
-v $PWD/data:/var/lib/mysql ：将主机当前目录下的data目录挂载到容器的 /var/lib/mysql 。
-
-e MYSQL_ROOT_PASSWORD=398023：初始化 root 用户的密码。
- -d mysql:5.7 ： 后面跟的内容就是上面docker pull 拉取时候后面写的内容 ,本文上面的命令是：
执行命令如下：
附录一个最简单的命令：
docker run -p 33061:3306 --name mysql --restart=always -e MYSQL_ROOT_PASSWORD=jiayou -d mysql:5.7
启动一个叫mysql的docker实例，对外端口33061，设置的root密码是jiayou ,使用的镜像是 mysql:5.7 --restart=always表示无论容器的退出代码是什么，Docker都会自动重启该容器。
再附录一个启动时候处理了时区问题的命令：【具体的使用参考：https://www.cnblogs.com/sxdcgaq8080/p/10057385.html】
docker run -p 33061:3306 --name mysql --restart=always -e MYSQL_ROOT_PASSWORD=398023 -v /etc/localtime:/etc/localtime:ro -v /etc/timezone:/etc/timezone:ro -d mysql:5.7
额外的参数 更改了mysql时区的问题。
5.最后查看容器的运行状况
docker ps
6.也可以查看容器的详细信息

7.查看mysql的运行日志
docker logs mysql4SXD
