Read first the Connection dialog
page to understand the dialog fields( host, port, user, etc. ), SSH tunnel, etc..
You can connect to Postgres using the user 'postgres'. The default port is 5432.
If you connect from a remote computer you have to enable the access from remote computers.
Check the following if you cannot connect to the database:
Enable Remote Connections
Step 1: Edit pg_hba.conf
On Postgres server there is a file called pg_hba.conf. On Windows it is located in the installation folder /data, on linux in /var/lib/pgsql/data/.
Edit the pg_hba.conf file and append the following configuration line, replacing 10.10.29.0 with your client machine IP :
host all all 10.10.29.0/24 trust
More simple, you can allow all hosts to connect by adding this line:
host all all 0.0.0.0/0 md5
Then restart the server. For this you may use the command below (replace the path to data folder).
pg_ctl.exe -D <path_to_data_folder> restart
Step 2 : Edit postgres.conf
To enable listening for all hosts, edit the file postgresql.conf ( on Windows located in Postgres installation folder /data, on linux in /var/lib/pgsql/data/ ),
find configuration line that read as follows: listen_addresses='localhost'. Change it to listen_addresses='*'
Eventually you can change this to your IP address. For example listen_addresses='188.8.131.52'
Search on google for 'postgresql enable remote access' to find further documentation.
Change User Password
You may change a user password from psql
using the statement below.
The default password is the one you set during Postgres installation.
ALTER USER <someUser> PASSWORD '<newPassword>';
Start Postgres Service
If Postgres service is not running, you won't be able to connect.
To enable Postgres Service follow this steps:
- Go to Start -> Control Panel -> System and Security -> Administrative Tools -> Component Services
- Open Service Local
- Find your postgres service name setup during installation (For Example: postgresql-9.3)
- Right click on the service name and click start.
To start the postgres service on linux just type in the console: service postgres start
Allow Postgres Connect Through Firewall
Open Windows Firewall by clicking the Start button Picture of the Start button, and then clicking Control Panel. In the search box, type firewall, and then click Windows Firewall.
In the left pane, click Advanced settings. Administrator permission required If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
In the Windows Firewall with Advanced Security dialog box, in the left pane, click Inbound Rules, and then, in the right pane, click New Rule.
Follow the instructions in the New Inbound Rule wizard. Make sure to select Add Port.
For the Port name use Postgres.
For the specific local port use 5432
Make sure to check off Allow the Connection
For When does this rule apply?
Put a check in Domain, private, and public.
Make sure to follow the directions above for creating an Outbound rule...basically the same way except you click Outbound Rules on the left pane.
We look forward to include more logic in our application which would allow us to use SSL connections.
