Can you test: #python2.6 >import psycopg2 >psycopg2.connect(database="prac2", user="postgres", password="password", >host="localhost")
Maybe the server is down, you have a firewall issue or your pg_hba.conf is not open for localhost connections: host all all 127.0.0.1 md5 hostssl all all 127.0.0.1 md5 (use 127.0.0.1 as ipv6 localhost address may conflict) Best regards, Mariano Reingart http://www.sistemasagiles.com.ar http://reingart.blogspot.com On Sun, Sep 25, 2011 at 4:06 PM, lucas <sjluk...@gmail.com> wrote: > hello one and all, > > i am having difficultly connecting postgres 9.1 under web2py v1.98.2 > on a centos 6.0 box which has python 2.6.5. i have psycopg2 2.4 > installed and working in python when i run the test > > #python2.6 web2py -S welcom -N -a 'password' > then >>import psycopg2 >> > > works just fine. however, when i put > > db = DAL('postgres://postgres:passwd@localhost:5432/prac2') > > and attempt to click on database administrator, i get for the > traceback > > Traceback (most recent call last): > File "/opt/web-apps/web2py/gluon/restricted.py", line 192, in > restricted > exec ccode in environment > File "/opt/web-apps/web2py/applications/prac2_with_postgresql/models/ > db.py", line 83, in <module> > db = DAL('postgres://root:@localhost:5432/prac2') > File "/opt/web-apps/web2py/gluon/dal.py", line 3981, in __init__ > raise RuntimeError, "Failure to connect, tried %d times:\n%s" % > (attempts, error) > RuntimeError: Failure to connect, tried 5 times: > could not connect to server: Permission denied > Is the server running on host "localhost" (127.0.0.1) and > accepting > TCP/IP connections on port 5432? > > any ideas on what i have not done properly??? thank you in advance > and have a great day. lucas
