Hi all,

   PostgreSQL version...: 9.5.5
   OS...........................: Oracle Linux 6.5 64 bits

   I am quite new in the PostgreSQL world and i'm trying to create a new db with the following sintax, using the "postgres" OS user:

 [postgres@vm-ora12 ~]$ createdb -h localhost -p 5432 -U postgres dbdev

createdb: could not connect to database template1: FATAL:  Ident authentication failed for user "postgres"

I did the install via YUM, as "root" user using the PostgreSQL repository. the service is ip and running:

[root@vm-ora12 ~]# service postgresql-9.5 status
postgresql-9.5 (pid  18507) is running...


Why am i getting the above error while trying to create a new database?

Thanks for the attention and help.

Hi,

   thanks for the attention and help.

   Actually, my installation didn't create the ".conf" files. What i have are the ".conf.sample", created at "/usr/pgsql-9.5/share" directory, so i created a copy of the "postgresql.conf" and "pg_hba.conf" and edited as follows:

[root@vm-ora12 share]# cat postgresql.conf
data_directory = '/usr/pgsql-9.5/share'
hba_file = '/usr/pgsql-9.5/share/pg_hba.conf'
ident_file = '/usr/pgsql-9.5/share/pg_ident.conf'


[root@vm-ora12 share]# cat pg_hba.conf
local   all         all                                     trust
host    all         all         127.0.0.1/32          trust
host    all         all         ::1/128                  trust
host    all         all         0.0.0.0/0               md5




After these changes, i restarted the service and i tryied to to create the DB, still without success.

Thanks again for the patience.

Hi,

   i found out where the config files were. I connected to the postgres database, executed the "SHOW data_directory" command and edited the correct "pg_hba.conf". After that, the "createdb" command worked properly.

Thanks for the attention.
