Hi Cesar,

      I have tried different combinations of setting:

1. The default setting, the service can start, but galaxy cannot connect to

local      all           all                           ident

host       all           all           127.0.0.1/32       ident

host       all           all           ::1/128  ident

2. the working setting on the Ubuntu machine (pgsql 9.1), but on CentOS, the service cannot start

local      all           all                           peer     

host       all           all           127.0.0.1/32       md5

host       all           all           ::1/128  md5

3. The setting I used to test the new created pgsql user and password under command line. Yes, the password is required under command line as planned

local      all           postgres                              ident

local      all           all                           md5

host       all           all           127.0.0.1/32       ident

host       all           all           ::1/128  ident

4. Your suggestion works magically

local      all           all                           ident

host       all           all           127.0.0.1/32       ident

host       all           all           ::1/128  ident

      I cannot thank you enough for this simple but magical tip, before which I never thought about to change host lines as “local” word is so attempting to set anything for localhost in that line.

Best regards!

Jun,

You need to change the value of host in 

pg_hba.conf from ident to trust and then start your psql service

Hi all,

       I followed the instruction on https://wiki.galaxyproject.org/Admin/Config/Performance/ProductionServer and managed to migrate to a postgresql on a Ubuntu machine. However when I tried on a CentOS 6.5, it failed.The steps are:

1. Create psql user galaxy: under psql prompt,

a. CREATE USER galaxy WITH PASSWORD 'galaxy';

b. CREATE DATABASE galaxy;

c. GRANT ALL PRIVILEGES ON DATABASE galaxy to galaxy;

2. test the created account: change authentication method to password in pg_hba.conf  and the username/password works

3. add postgresql://galaxy:galaxy@localhost/galaxy to universal_wsgi.ini

4. sh run.sh gave me the error saying  FATAL: Ident authentication failed for user “galaxy”

5. even I changed back to the default IDENT authentication for postgresql in pg_hba.conf, the same error message appeared.

Could anyone help me to spot the error here?

Best regards!

Jun
