环境:两台华为云服务器

目标：mysql集群（一个管理节点，一个数据节点+SQL节点）

1、已经安装管理节点、ndb_mgmd（成功）

2、在数据节点安装ndbd的时候报错

[root@server2 bin]# ./ndbd --initial
2021-04-26 19:03:13 [ndbd] INFO – Angel connected to ‘121.36.80.187:1186’
2021-04-26 19:03:13 [ndbd] INFO – Angel allocated nodeid: 2
2021-04-26 19:03:13 [ndbd] ERROR – Could not fetch configuration/invalid configuration, error: ‘The hostname this node should have according to the configuration does not match a local interface. Attempt to bind ‘123.60.17.157’ failed with error: 99 ‘Cannot assign requested address’’
[root@server2 bin]#

管理节点的config.ini配置
