搭建环境

问题一：使用Ubuntu17，发现源出现问题

# apt-get update
Hit:1 http://ppa.launchpad.net/webupd8team/sublime-text-3/ubuntu zesty InRelease
Ign:2 http://cn.archive.ubuntu.com/ubuntu zesty InRelease
Err:5 http://cn.archive.ubuntu.com/ubuntu zesty Release
  404  Not Found [IP: 91.189.91.23 80]
Err:6 http://cn.archive.ubuntu.com/ubuntu zesty-security Release

  404  Not Found [IP: 91.189.91.23 80]

E: The repository 'http://cn.archive.ubuntu.com/ubuntu zesty Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

改为使用镜像ubuntu18

问题二：卡住安装tzdata

tzdata会以交互方式提醒用户选择使用位置。会在这一直卡住
首选的方法是在Dockerfile的第一条RUN之前加入以下配置：

ENV DEBIAN_FRONTEND=noninteractive
、

问题三：mysql5.6官方文档说命令行方式写密码不安全

mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

安装低版本或把地址账号密码写入my.cnf
添加源
add-apt-repository ‘deb http://archive.ubuntu.com/ubuntu trusty main’
add-apt-repository ‘deb http://archive.ubuntu.com/ubuntu trusty main’

唉，未解决，脑阔炸了
