Php Postfixadmin不与Postgres合作

我对postgres和postfix都是新手，我决定使用postfixadmin和postgres来获得更多经验，我已经完成了不同网站中提到的详细步骤，并且我检查了postgres的另一个工作安装，但没有postfixadmin，但是每当我从中访问setup.php for postfixadmin时，我都会得到：

Error: Can't connect to database
Please edit the $CONF['database_*'] parameters in config.inc.php.
DEBUG INFORMATION:
Connect: failed to connect to database.

我将postfix管理员配置为最初使用postfix用户，但由于默认情况下postfix创建为no login user，因此我创建了另一个名为admin的用户，并在config.inc.php中对其进行了更改，但我仍然收到相同的错误

以下是在系统上创建的与此内容相关的用户：

# cat /etc/passwd
root:x:0:0:root:/root:/bin/bash
postfix:x:89:89::/var/spool/postfix:/sbin/nologin
postgres:x:26:26:PostgreSQL Server:/var/lib/pgsql:/bin/bash
admin:x:500:500::/home/admin:/bin/bash

我在这里配置Postgres中的用户管理员：

# su - postgres
-bash-4.1$ template1
-bash: template1: command not found
-bash-4.1$ template1#
-bash: template1#: command not found
-bash-4.1$ psql template1
psql (8.4.18)
Type "help" for help.
template1=# CREATE USER admin WITH PASSWORD 'complexpassword';
CREATE ROLE
template1=# GRANT ALL PRIVILEGES ON DATABASE postfix to admin;
GRANT
template1=# \q
-bash-4.1$ logout

以下是Postgres的配置：

以下是postgresql.conf：

这里我正在测试用户管理员：

# su - admin
$ psql -d postfix -U admin
psql (8.4.18)
Type "help" for help.
postfix=> exit
postfix-> \q

这里我正在测试postfix用户nologin：

# su - postfix

以下是显示Postgres正在收听posrt 5432的检查：

但真正奇怪的是，当我尝试运行setup.php页面时，我可以看到以下内容：

# netstat -an| grep 5432

pg_hba.conf是：

有人能告诉我怎么回事吗？

在pg_hba.conf中查找此文件与postgresql.conf位于同一目录中，该行以host开头，其中包含127.0.0.1/32，以ident结尾，并将ident更改为md5。重新加载/重新启动Postgres
