Client tools connect to the database through the database master node. Therefore, before connecting, you need to obtain the IP address of the server where the database master node is located and the port number of the database master node.
⚫ Step 1: Log in to the master node of the database as the operating system user omm.
⚫ Step 2: Use the "gs_om -t status --detail" command to query the status of each instance of openGauss.
The IP addresses of the servers where the database master node instance is deployed as above are 192.168.10.11 respectively, and the data path of the database master node is "/srv/BigData/gaussdb/data1/dbnode".
⚫ Step 3: Confirm the port number of the database master node. Check the port number information in the postgresql.conf file under the data path of the database master node found in step 2. An example is as follows:
