Question

这是我收到的错误，它拒绝连接到数据库

Traceback (most recent call last):
  File "db.py", line 2, in <module>
    conn = psycopg2.connect(host="176.58.104.XXX",database="XXXX", user="XXXXX", password="XXXXX")
  File "c://addr", line 130, in connect
    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
psycopg2.OperationalError: could not connect to server: Connection refused (0x0000274D/10061)
        Is the server running on host "176.58.104.XXX" and accepting
        TCP/IP connections on port 5432?

我已经尽可能地诊断出原因。我的postgresql.conf文件在这里，所以我将它们全部更新了，除了示例

locate postgresql.conf
/etc/postgresql/9.5/main/postgresql.conf
/usr/lib/tmpfiles.d/postgresql.conf
/usr/share/postgresql/9.5/postgresql.conf.sample

与

#------------------------------------------------------------------------------
# CONNECTIONS AND AUTHENTICATION
#------------------------------------------------------------------------------

# - Connection Settings -

#listen_addresses = '*'         # what IP address(es) to listen on;
                                        # comma-separated list of addresses;
                                        # defaults to 'localhost'; use '*' for all

然后更新pg_hba.conf

host    all             all              0.0.0.0/0                       md5
host    all             all              ::/0                            md5

并重新启动sudo systemctl重新启动PostgreSQL

我遵循了这些说明https://zaiste.net/postgresql_allow_remote_connections/

但是我仍然遇到错误

这是我的netstat -nlt，我仍然可以看到我的连接与127.0.0.1绑定

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State
tcp        0      0 127.0.0.1:3306          0.0.0.0:*               LISTEN
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN
tcp        0      0 127.0.0.1:5432          0.0.0.0:*               LISTEN

我错过了一些步骤吗？

Answer 1

默认情况下，＃位于#listen_addresses ='*'前面。

没看到。

尝试连接到数据库Postgres
