环境

系统平台： N/A

版本： 4.1.1

症状

使用psql远程连接数据库报错：Connection refused  和 No route to host。

 

1、psql: could not connect to server: Connection refused

 

[highgo@hgdb ~]$ psql -h 192.168.10.123 -p 5866

psql: could not connect to server: Connection refused

      Is the server running on host "192.168.10.123" and accepting  TCP/IP connections on port 5866?

2、psql: could not connect to server:No route to host 

[highgo@hgdb ~]$ psql -h 192.168.10.123 -p 5866

psql: could not connect to server: No route to host

      Is the server running on host "192.168.10.123" and accepting      TCP/IP connections on port 5866?

问题原因

出现报错Connection refused，表示目标主机明确拒绝了这次连接。

出现报错No route to host，表示可能是一个网络问题，并不是目标主机的回复。
