无法通过 pgadmin3 登录到新的 PostgreSQL 服务器(在 Fedora 上)

Can't login to new PostgreSQL server via pgadmin3 (on Fedora)

我正在尝试在 Fedora 25 上安装 PostgreSQL。

我编辑 postgresql.conf 以包括:

listen_addresses = '*'  
port = 5432

我编辑 pg_hba.conf 以包括:

local   all all                         trust
local   all all 192.168.0.0/24          trust
local   all all 127.0.0.1/32            trust

两者都可以看作是绝望的,但我正在努力建立联系。

我可以通过命令行 psql 访问 PostgreSQL 服务器

但是我无法通过 pgadmin3 建立连接——使用相同的登录凭据。

我收到以下消息:

Ident authentication failed
The server doesn't accept the current user: The server reports 
FATAL: Ident authentication failed for user "postgres" 
If this message appears, the pg_hba.conf entry found for your client / user / database combination is set to "ident" authentication. Some distributions, e.g. Debian, have this by default. To perform ident based authentication successfully, you need additional setup; see the PostgreSQL help for this. For a beginner, it might be more appropriate to use a different authentication method; MD5 encrypted passwords are a good choice, which can be configured by an entry in pg_hba.conf like this: 
host all all 192.168.0.0/24 md5 
This example grants MD5 encrypted password access to all databases to all users on the private network 192.168.0.0/24. 
You can use the pg_hba.conf editor that is built into pgAdmin III to edit the pg_hba.conf configuration file. After changing pg_hba.conf, you need to trigger a server configuration reload using pg_ctl or by stopping and restarting the server process. 

任何人都可以看到任何明显的错误,或者建议我可以尝试的可能性。

为了测试,您可以尝试使用 pg_hba.conf 行(第一行用于 IPv4,第二行用于 IPv6):

host all all 0.0.0.0/0 trust
host all all ::0/0     trust

这允许所有网络连接在没有密码的情况下成功,所以不要在测试后留下这些行。

注意pg_hba.conf是从上到下处理的,使用第一个匹配的行。所以你想把这些线放在最上面。

使用 pg_ctl reload 重新加载后,检查 PostgreSQL 日志文件是否配置文件中有任何错误。

再折腾一番后...
我的 pg_hba.conf 现在是这样的:

# My desperate access - including a very open option...
local all all trust
host all all 0.0.0.0/0 trust

# "local" is for Unix domain socket connections only
local   all             all                                     trust

# IPv4 local connections:
host    all             all             127.0.0.1/32            trust

# IPv6 local connections:
host    all             all             ::1/128                 trust

前两行没有给我做,但当我转后三行时 全部使用 'trust',然后我获得了访问权限 - 也是通过 pgadmin3
