2. 问题（故障）原因

因为docker宿主机没有配置DNS，访问云端rds库访问不通。

3. 解决

（1）docker宿主机配置DNS：

[root@local zcbusServer]# cat /etc/resolv.conf 
; generated by /usr/sbin/dhclient-script
nameserver 10.49.0.30
nameserver 10.49.0.31

（2）zcbus的docker容器整体重启：

[root@local zcbusServer]# ./restart.sh 
Restarting zcbusdb ... done
Restarting zcbuszookeeper ... done
Restarting zcbuskafka ... done
Restarting zcbusserver ... done
Restarting zcbusweb ... done
