Verifying the Installation

Use the gs_checkos tool provided by openGauss to check the OS status.


  • 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.


  1. Log in to a server as user root.

  2. 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.


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
Checking items:
    A1. [ OS version status ]                                   : Normal
    A2. [ Kernel version status ]                               : Normal
    A3. [ Unicode status ]                                      : Normal
