mongo replicaset=rs0 com.mongodb.MongoSocketException: centosc

1、描述虚拟机搭建mongo副本集虚拟机的设定的hostname为： centosc。虚拟机IP为 192.168.25.129 搭建三个副本集端口分别为，28017、28018、28019 ，运行mongo副本集报错，报错信息如下：

2、说明及解决办法

    原来没有报错不知道什么原因、可能是mongo集群搭建完一直没有做虚拟机重启可能是。反正出现找个错误原因是实体机无法识别虚拟机hostname名称，在实体机host下添加一行信息：192.168.25.129 即可

    既：
