我是postgres和postfix的新手，我决定使用Postfix的postfixadmin获得如此实力，我已经完成了不同网站中提到的详细步骤，并且我已经检查了Postgres的另一个工作安装（但是没有postfixadmin ），但每当我从http://mydomain.com:8080访问来自{{3}}的postfixadmin的setup.php时，我都会：
Error: Can't connect to database
Please edit the $CONF['database_*'] parameters in config.inc.php.
DEBUG INFORMATION:
Connect: failed to connect to database.
我将postfixadmin配置为最初使用postfix用户，但由于postfix默认创建为无登录用户，所以我创建了另一个名为admin的用户，并在config.inc.php中更改了此项，但我仍然得到相同的错误
以下是在系统上创建的与此相关的用户：
# cat /etc/passwd
root:x:0:0:root:/root:/bin/bash
postfix:x:89:89::/var/spool/postfix:/sbin/nologin
postgres:x:26:26:PostgreSQL Server:/var/lib/pgsql:/bin/bash
admin:x:500:500::/home/admin:/bin/bash
我在Postgres中配置用户admin：
# su - postgres
-bash-4.1$ 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：
-bash-4.1$ psql
psql (8.4.18)
Type "help" for help.
postgres=# \list
List of databases

这是postgresql.conf：
#cat postgresql.conf

我在这里测试用户admin：
# 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

Called by create-mailbox.php if $CONF['maildir_name_hook'] == '<name_of_the_function>'
- allows for customized maildir paths determined by a custom function
- the example below will prepend a single-character directory to the
beginning of the maildir, splitting domains more or less evenly over
36 directories for improved filesystem performance with large numbers
of domains.
Returns: maildir path

以下是显示Postgres正在收听posrt 5432的检查：
#netstat -an|grep 5432

unix 2 [ ACC ] STREAM LISTENING 12136 /tmp/.s.PGSQL.5432
# telnet localhost 5432
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
^]
telnet> quit
Connection closed.
但是当我尝试运行setup.php页面时，我真的很奇怪，我可以看到以下内容：
# netstat -an| grep 5432
tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:45445 127.0.0.1:5432 TIME_WAIT
unix 2 [ ACC ] STREAM LISTENING 12136 /tmp/.s.PGSQL.5432
Postgres'日志包含：
LOG: could not connect to Ident server at address "127.0.0.1", port 113: Connection refused
FATAL: Ident authentication failed for user "postfix"
LOG: could not connect to Ident server at address "127.0.0.1", port 113: Connection refused

而pg_hba.conf是：
local all all ident
host all all 127.0.0.1/32 ident
host all all ::1/128 ident
有人可以指导我出错了吗？
答案 0 :(得分：0)
在pg_hba.conf中查找（此文件与postgresql.conf在同一目录中）以＆＃34; host＆＃34;开头的行，包含＆＃34; 127.0.0.1/32& ＃34;在其中以＆＃34; ident＆＃34;结尾并改变＆＃34; ident＆＃34;到＆＃34; md5＆＃34;。重新加载/重新启动Postgres。
