进入mysql容器
操作vi etc/mysql/my.cnf
默认是不安装vi编辑器的，下面安装vi
更新安装包
apt-get update
安装vim
执行这条语句
apt-get install vim
到修改docker容器里面的mysql数据库密码了
启动mysql容器
docker exec -it mysql /bin/bash
编辑配置文件
我这里是没有这个配置文件，直接编辑即可，有的忽略
vi /etc/mysql/conf.d/docker.cnf
加上这4段
[mysqld]
skip-host-cache
skip-name-resolve
skip-grant-tables 跳过权限认证
保存退出
root@25cf6844e4d5:/# exit
exit
重启mysql容器
我命名的mysql容器名是mysql01，按照自己的名字重启
[root@rzk ~]# docker restart mysql01
mysql01
进入mysql容器,连接mysql
docker exec -it mysql /bin/bash
[root@rzk ~]# docker exec -it mysql01 /bin/bash
root@25cf6844e4d5:/# mysql -u root -p
Enter password:

[mysqld]
skip-host-cache
skip-name-resolve
skip-grant-tables 跳过权限认证

启动
-d 后台运行
-p 端口映射
-v 卷挂载
-e 环境配置
–name 容器名字
-v /home/mysql/data:/var/lib/mysql 把mysql里面的东西挂载到data里面
[root@iZwz94cw1gup8aldclit1qZ home]# docker run -d -p 3310:3306 -v /home/mysql/conf:/etc/mysql/conf.d -v /home/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -睿共享 -name mysql01 mysql:5.7

启动成功之后，我们本地使用sqlyog来连接测试一下
sqlyog -连接到服务器的3310 — 331- 和容器内的3306映射，这个时候我们可以连接上了在本地测试一个
睿共享 数据库，查看一下我们映射的路径是否ok！步骤在SQLyog 新建一个test数据库，然后去终端mysql/data查看会不会出现一个test名字的文件
