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!

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!
