解决方法:
!、打开Postgresql安装目录下的data文件夹,找到pg_hba.conf文件并打开
在# TYPE DATABASE USER CIDR-ADDRESS METHOD的下面:
加上一句:
host all all 0.0.0.0/0 md5
2、更改postgresql.conf下
#listen_addresses = 'localhost' # what IP address(es) to listen on;
为
listen_addresses = '*' # what IP address(es) to listen on;
记得去掉listen_addresses前的#号
