hi, all I have install calamari server, calamari client and diamond on a centos server, Then i run the following command: {code} [root@centos65 content]# sudo calamari-ctl initialize [INFO] Loading configuration.. [INFO] Starting/enabling salt... [INFO] Starting/enabling postgres... [INFO] Initializing database... [INFO] Initializing web interface... [INFO] You will now be prompted for login details for the administrative user account. This is the account you will use to log into the web interface once setup is complete. Username (leave blank to use 'root'): Email address: xxx@xxxxxxx Password: Password (again): Superuser created successfully. [INFO] Starting/enabling services... [INFO] Restarting services… {code} The command hold on and can not go on. Then i check the log /var/log/calamari/cthulhu.log and find the following error: {code} OperationalError: (OperationalError) could not connect to server: Connection refused Is the server running on host "localhost" and accepting TCP/IP connections on port 5432?
