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
