详细介绍安装 MySQL 客户端 mysql-workbench 的步骤。
在安装好 MySQL 之后可以需要可视化界面，可以选择官方提供的 mysql-workbench 客户端。
实验环境
Ubuntu 版本：ubuntu 14.04
MySQL版本：MySQL 5.5
mysql-workbench 版本：mysql-workbench-community-6.2.5-1ubu1404-amd64
下载
在火狐Firefox浏览器中输入官方下载地址：https://dev.mysql.com/downloads/workbench/，
然后找到下载地方，如下图所示，在“select Operating System”中选择“Ubuntu Linux”，然后在“Select OS Version”中只有 ubuntu 16 版本，如果你的系统是 ubuntu 16 ，那么可以选择相应的版本进行下载。 
因为我的系统是 ubuntu 14.04，所以需要点击上图右边的“Looking for previous GA versions？”
然后跳转到如下界面，然后选择相应的软件版本 
最后点击右下角的“Download”。
跳转到下面的界面，直接点击“No thanks, just start my download” 
然后保存文件，点击“OK”下载。 
安装
为了避免权限问题出错，我这里使用 root 权限，切换到下载目录，执行如下命令
dpkg -i mysql-workbench-community-6.2.5-1ubu1404-amd64.deb 
如果出现如下提示
