Fabric : 10.101.90.5
Master : 10.101.90.6
Slave: 10.101.90.7
我将奴隶添加到群组中，我收到以下错误：
mysqlfabric group add mygroup 10.101.90.7
Password for admin:
Fabric UUID: 5calable-a007-feed-food-cab3fe13249e
Time-to-live: 1
ServerError: Error accessing server(10.101.90.7):
2003: Cannot connect to MySQL server on '10.101.90.7:3306'(113 No route to host)
有谁知道为什么会这样？我该如何解决？
