在此主要解决的是在HUE过程中集成MYSQL管理时，遇到了数据库开发中常见的中文乱码问题。先来看看集成MySQL的配置描述：

这段配置很简单理解起来也难，可实际运行过程中就遇到了两个难题，先是显示出现乱码问题，另外就是配置中给的文档链接地址是**404**，真是尴尬啦。追溯下来最后到找到关于
sql-mode
设置，想下应该是支持MySQL的命令吧，然后就在配置最后一段加入如下的命令：
1
| options={ "init_command":"SET NAMES `utf8`"}
|
实验了一下，乱码问题OK，中文显示正常。
其实要不生产环境的话就不用如此的折腾，最简单的办法就是更新my.ini配置，你懂的。
