Postgresql 设置博士后：Can'；t远程连接到Postgres服务器（debian）

我在从外部服务器连接数据库时遇到问题。我读了很多关于这个主题的话题。什么都没有

Trying 127.0.0.1...
Connected to localhost.localdomain.

Postgresql 8.4/Debian

Trying 127.0.0.1...
Connected to localhost.localdomain.

My/etc/postgresql/8.4/main/postgresql.conf：

listen_addresses = '*'
port = 5432
max_connections = 100

local all all trust
host all all 127.0.0.1/32 trust
host all all ::1/128 trust
host all all 0.0.0.0/0 trust

Trying 127.0.0.1...
Connected to localhost.localdomain.

My/etc/postgresql/8.4/main/pg_hba.conf：

listen_addresses = '*'
port = 5432
max_connections = 100

local all all trust
host all all 127.0.0.1/32 trust
host all all ::1/128 trust
host all all 0.0.0.0/0 trust

Trying 127.0.0.1...
Connected to localhost.localdomain.

netstat-nlp | grep5432

Trying 127.0.0.1...
Connected to localhost.localdomain.

telnet localhost 5432

Trying 127.0.0.1...
Connected to localhost.localdomain.

但是当我尝试从我的计算机连接时，我总是得到“无法建立到的连接”

Trying 127.0.0.1...
Connected to localhost.localdomain.

知道我做错了什么吗？：/感谢您的帮助：）

您是否在运行postgres的服务器上禁用了防火墙？

Trying 127.0.0.1...
Connected to localhost.localdomain.

---

如果没有，请禁用并测试。如果您能够在禁用防火墙后进行连接，则需要打开防火墙中的端口5432。

检查IPTABLES，确保其未运行：

Trying 127.0.0.1...
Connected to localhost.localdomain.

iptables -L

Trying 127.0.0.1...
Connected to localhost.localdomain.

---

如果它正在运行且默认规则已就位，则可能会导致问题。

可能是与IPv6相关的问题，请尝试通过使用

-h

显式添加服务器的ipv4地址来远程连接

Trying 127.0.0.1...
Connected to localhost.localdomain.
