在之前的博客我们搭建了基本得Docker 环境。 如下：
Linux 7.7 安装 Docker
https://www.cndba.cn/dave/article/4100
但是使用vim更改docker 中的文件时，提示没有vim 命令。
[root@www.cndba.cn ~]# docker exec -it mysqlserver bash
root@34ad82852c64:/# vi /etc/mysql/my.cnf
bash: vi: command not found
此时需要安装vim 命令，但通过debian 官方的源，更新太慢：

所以需要更改apt-get的源，但docker中现在还没有vim命令，所以无法直接修改。这里使用cp命令，曲线救国一下，先将源文件cp到物理主机，修改之后，在cp回去。
