Logging into PostgreSQL of Yugaware for a YBA Installer-Based Installation

Introduction

This article provides step-by-step instructions to log into PostgreSQL of Yugaware for a YBA (Yugabyte Anywhere) installer-based installation. Ensure you have the appropriate version information for the commands and paths used.

Steps to Connect to PostgreSQL

1. Navigate to the PostgreSQL Binary Directory

   Based on the YugabyteDB version you are using, navigate to the PostgreSQL binary directory. For example, if you are using version 2.21.1.0-b271, the directory path would be:

   cd /opt/yugabyte/software/2.21.1.0-b271/pgsql/bin

    

2. Attempting Connection Without Host Specification

   If you attempt to connect to PostgreSQL without specifying the host (-h option), you may encounter the following error:

   ./psql -U postgres -d yugaware psql: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory Is the server running locally and accepting connections on that socket?

    

3. Correct Command to Connect

   To successfully connect to the PostgreSQL instance, you must specify the host as localhost. Use the following command:

   ./psql -U postgres -d yugaware -h localhost

    

4. Check Bind Address Using netstat

   To verify the bind address of PostgreSQL, you can use the netstat command on the YBA platform node. This can help diagnose if PostgreSQL is listening on the expected address and port.

   Run the following command:

   netstat -tualpn | grep -i 5432

   You might see an output similar to this:

    

   (Not all processes could be identified, non-owned process info
    will not be shown, you would have to be root to see it all.)
   tcp        0      0 127.0.0.1:5432          0.0.0.0:*               LISTEN      -
   tcp        0      0 127.0.0.1:5432          127.0.0.1:44756         ESTABLISHED -
   tcp        0      0 127.0.0.1:5432          127.0.0.1:52286         ESTABLISHED -

    

   Summary

   To connect to PostgreSQL for Yugaware in a YBA installer-based installation, ensure you navigate to the correct PostgreSQL binary directory, specify the host as localhost when connecting, and use netstat to check if PostgreSQL is listening on the correct address and port. Remember, the default listen address for PostgreSQL is 127.0.0.1 or localhost
