我已经从 PGDG ppa 在 Ubuntu Trusty 上安装了 Postgresql 9.4。我创建了一个数据库并将其设置listen-addresses
为“*”。我已在 pg_hba.conf 文件中添加了一个条目。我可以毫无问题地在本地连接。这是我的 pg_hba.conf 中的条目:
host all tarka 192.168.0.0/24 md5
问题是该端口似乎被 UFW 阻止了。我尝试了 ufw 命令的几种变体来允许 postgres,例如
sudo ufw allow postgresql/tcp
sudo ufw allow 5432/tcp
以及最近
sudo ufw allow from 192.168.0.0/24 to any port 5432
我每次都重新启动ufw。
目前的状态是这样的:
sudo ufw status verbose
Status: active
Logging: on (low)
Default: allow (incoming), allow (outgoing), disabled (routed)
New profiles: skip
To Action From
-- ------ ----
22 ALLOW IN Anywhere
5432 ALLOW IN 192.168.0.0/24
22 (v6) ALLOW IN Anywhere (v6)
中的条目iptables
似乎有效:
Chain ufw-user-input (1 references)
target prot opt source destination
ACCEPT tcp -- anywhere anywhere tcp dpt:ssh
ACCEPT udp -- anywhere anywhere udp dpt:ssh
ACCEPT tcp -- 192.168.0.0/24 anywhere tcp dpt:postgresql
ACCEPT udp -- 192.168.0.0/24 anywhere udp dpt:postgresql
尽管如此,当我尝试从远程计算机连接时,ufw 会记录:
Sep 2 13:55:28 estuary kernel: [242754.395342] [UFW BLOCK] IN=eth0 OUT= MAC=94:de:80:27:4a:7e:b4:75:0e:97:21:29:08:00 SRC=192.168.0.13 DST=192.168.0.12 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=43525 DF PROTO=TCP SPT=36382 DPT=21 WINDOW=29200 RES=0x00 SYN URGP=0
事实上,我什至无法通过禁用 ufw 来连接。在所有情况下,nmap
报告端口 5432 均已关闭:
nmap estuary -p5432
Starting Nmap 6.40 ( http://nmap.org ) at 2015-09-02 16:43 PDT
Nmap scan report for estuary (192.168.0.12)
Host is up (0.0059s latency).
PORT STATE SERVICE
5432/tcp closed postgresql
此外,我nginx
作为网络服务器运行,并且可以从另一台计算机完全访问它。
我怎样才能让 ufw(或任何实际执行此操作的东西)停止阻塞端口 5432?

只是注意到在你的问题中你有带有连字符的“listen-addresses” - 文档有一个下划线(“listen_addresses”)
