We are looking for an experienced Linux server administrator or DevOps professional to troubleshoot and fix a PostgreSQL connection issue on our Apache/Passenger-based application.
Issue Details: -Our application fails to connect to the PostgreSQL database and shows the following error:
"connection to server at "172.17.0.1", port 5433 failed: Connection refused Is the server running on that host and accepting TCP/IP connections?"
-The issue seems to be related to database connectivity, firewall settings, or server configuration. -The PostgreSQL database is running on port 5433, not the default 5432. -The application is deployed using Apache + Passenger.
Expected Fix: -Diagnose and fix the PostgreSQL connection issue. -Ensure the application can successfully connect to the database. -Verify and update PostgreSQL, firewall, and network configurations if needed. -Restart necessary services (Apache, Passenger, PostgreSQL) after the fix. -Provide documentation on what was changed for future reference.
Requirements: -Experience with Linux servers (Ubuntu or Debian preferred). -Strong knowledge of PostgreSQL configuration and troubleshooting. -Experience with Apache + Passenger. -Familiarity with Docker (if the database is running inside a container).
If you are confident in fixing this issue, please apply with: -Your relevant experience -Estimated time to complete the fix -Any clarifying questions
Looking forward to working with an expert who can resolve this quickly!
