ubuntu 18.04 安装mysql 遇到语言格式不兼容性问题解决

安装mysql的时候，遇到了这样一个错误：
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset),
    LC_ALL = (unset),
    LANG = "en_US.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

实际上，在stackooverflow上，有很多解决方法，我的解决方法如下：

自己测试的方法如下：

sudo locale-gen en_US en_US.UTF-8
sudo dpkg-reconfigure locales
