Keetle链接MySQL数据库是报错误，

[weixin_38049770]

 开发四年只会写业务代码，分布式高并发都不会还做程序员？->>>    在用kettle链接MySQL数据库时出现如下错误，已经三天了，不知道解决办法，望大神们帮忙，,这里说明一下，我已经能够用eclipse链接到数据库了， 错误连接数据库 [test] : org.pentaho.di.core.exception.KettleDatabaseException:  Error occurred while trying to connect to the database Error connecting to database: (using class org.gjt.mm.mysql.Driver) Communications link failure The last packet sent successfully to the server was 0 milliseconds ago.
