我无法从我的机器连接到运行Postgres的服务器。我想我已经正确配置了它。服务器上没有防火墙。
我在Ubuntu 12.04 LTS上运行Postgres 9.1.9
这是来自/etc/postgresql/9.1/main/pg_hba.conf
local all postgres peer
# TYPE DATABASE USER ADDRESS METHOD
local all all peer
host all all 0.0.0.0/0 md5
host all all ::1/128 md5
我在/etc/postgresql/9.1/main/postgresql.conf中有listen_addresses = '*'
我已多次停止并启动该服务。
netstat -tulnp

tcp6 0 0 :::5432 :::* LISTEN 30239/postgres
我的iptable是空的。
当我尝试使用
连接到服务器时psql -U postgres -h <MY_IP>
我明白了:
psql: could not connect to server: Operation timed out
Is the server running on host "<MY_IP>" and accepting
TCP/IP connections on port 5432?
有任何帮助吗?感谢
