[postgis-users] PostGIS and Mapserver

[Ethan Alpert]

Try to connect to the postgres server manually with psql:

psql -U postgres -h myserver.mydomain

If you can't connect then the host you are connecting from is not
allowed. Look at the file $PG_HOME/pg_hba.conf and make sure
$PG_HOME/postgresql.conf has networking set up.

Hi list,

I am trying to access postgis via mapserver (a cgi server) but the 
resoult is allways a problem. Could anobody take a look on my problem ?

the stack trace is shown below:

msDrawMap(): Image handling error. Failed to draw layer named 'bairros'.
msPOSTGISLayerOpen(): Query error. couldnt make connection to DB with 
connect string 'user=postgres password=pt dbname=db1 
host=myserver.mydomain port=5432'.
Error reported was 'could not create socket: Permission denied '. This
error occured when trying to make a connection to the specified 
postgresql server.
Most commonly this is caused by
(1) incorrect connection string
(2) you didnt specify a 'user=...' in your connection string
(3) the postmaster (postgresql server) isnt running
(4) you are not allowing TCP/IP connection to the postmaster
(5) your postmaster is not running on the correct port - if its not on 
5432 you must specify a 'port=...'
(6) the security on your system does not allow the webserver (usually 
user 'nobody') to make socket connections to the postmaster
(7) you forgot to specify a 'host=...' if the postmaster is on a 
different machine
(8) you made a typo

My best regards
Ezequias
