我试图使用ufw使用sudo ufw allow 5432 / tcp在ubuntu上打开端口5432
然后我使用nmap来查看端口5432是否已打开,我得到了这个：
root@domain:~# sudo nmap -sS -O 127.0.0.1 Starting Nmap 5.21 ( http://nmap.org ) at 2011-12-01 14:28 MSK Nmap scan report for localhost.localdomain (127.0.0.1) Host is up (0.000084s latency).

1xx.xxx.xxx.xxx是我服务器的IP.
我编辑了pg_hba.conf：
# DO NOT DISABLE! # If you change this first entry you will need to make sure that the # database # super user can access the database using some other method. # Noninteractive # access to all databases is required during automatic maintenance # (custom daily cronjobs,replication,and similar tasks). # # Database administrative login by UNIX sockets local all postgres ident # TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only local all all ident # IPv4 local connections: host all all 0.0.0.0/0 md5 # IPv6 local connections: host all all ::1/128 md5
但是5432端口尚未打开.
