linux – 无法从我的Mac连接到VM上的PSQL数据库

前端之家收集整理的这篇文章主要介绍了linux – 无法从我的Mac连接到VM上的PSQL数据库前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
尝试使用pgAdmin3从我的Mac上连接到我的CentOS VM上的Psql数据库.出现以下错误
Access to database denied
The server doesn't grant access to the database: the server reports 
FATAL: no pg_hba.conf entry for host "172.16.30.1",user "gpadmin",database "postgres",SSL off

VM的IP地址是172.16.30.139,因此我将其用作主机.我在pg_hba.conf文件添加了以下内容

local all     gpadmin     ident
#host all     gpadmin     127.0.0.1/28      trust
#host all     gpadmin     192.168.249.131/32    trust
local gpperfmon   gpmon                             md5
host     all     all     192.168.2.109   md5

其中192.168.2.109是我的Mac内部IP地址.

任何帮助,将不胜感激.

编辑:

我还运行了一个tcpdump然后尝试连接并查看以下日志(但我不知道如何阅读它们):

解决方法

192.168.2.109可能是您内部网络上的mac地址,但172.16.30.1是虚拟网络上用于与VM通信的mac地址,这是您需要在pg_hba.conf中配置的地址.
