Verifying the Installation
Use the gs_checkos tool provided by openGauss to check the OS status.
Prerequisites
- The hardware and network are working properly.
- The trust relationship of user root among the hosts is normal.
- Only user root is authorized to run the gs_checkos command.
Procedure
Log in to a server as user root.
Run the following command to check OS parameters of servers where the openGauss nodes are deployed:
gs_checkos -i A
Check the OS parameters to ensure that the openGauss has passed the pre-installation check and can efficiently operate after it is installed. For details about the check items, see “gs_checkos” in the Tool Reference.
Examples
Before running the gs_checkos command, execute the gs_preinstall script to prepare the environment. The following uses parameter A as an example:
gs_checkos -i A
