Linux下,kettle连接MySQL资源库问题

Processing stopped because of an error:

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

跪求各位大神请教!!!

mysql数据库是否启动,你的数据库连接参数配置正确了没有

首先感谢楼上两位大神的回答,再说一下问题的错误原因:
1、是因为这部署kettle的这台服务器上没有MySQL的客户端,所以根本无法访问到数据库,太疏忽了。。。
2、接下来换了一台装有MySQL客户端的服务器,进行部署。也是有问题,是由于我创建的资源库用户没有权限访问那台数据库(只开通了外网连接权限,未开通localhost权限)
---赋予权限(外网)
grant all on lisnew.* to ods_rep@"%" identified by 'ods_rep';
---赋予权限(内网/本地)
grant all privileges on . to ods_rep@localhost identified by 'ods_rep';
【注】:ods_rep用户为资源库用户,命令含义可在百度查询
所以,总体来说,还是连接数据库的问题,希望有所帮助!
