错误一：

集群初始化时，报错：

replSetInitiate quorum check failed because not all proposed set members responded affirmatively

: 192.168.2.187:27017 failed with Error connecting to 192.168.2.187:27017 :: 

caused by :: Connection refused, 192.168.2.188:27017 failed with Error 

connecting to 192.168.2.188:27017 :: caused by :: Connection refused"

如下：

> rs.initiate(config)

{

"ok" : 0,

"errmsg" : "replSetInitiate quorum check failed because not all proposed set members responded affirmatively: 192.168.2.187:27017 failed with Error connecting to 192.168.2.187:27017 :: caused by :: Connection refused, 192.168.2.188:27017 failed with Error connecting to 192.168.2.188:27017 :: caused by :: Connection refused",

"code" : 74,

"codeName" : "NodeNotFound"

}

问题原因：

主从库配置文件里没有配置 bind_ip参数，默认只能远程连接数据库

可以在从节点远程连接主库进行测试

mongo --host 192.168.2.222 --port 27017

也会出现Connection refused错误

解决方案：

主从库配置文件mongodb.conf添加bind_ip参数，重启数据库。

bind_ip = 0.0.0.0
