gs_install

Background

Database deployment is a complex process. gs_install, provided by openGauss, is used to install and deploy openGauss.

Installation and deployment of openGauss require you to specify a configuration file, in which the program installation path, instance data directory, the primary/standby relationship, the number of instances, and the service IP address of each instance are specified.

Prerequisites

  • You have successfully executed the gs_preinstall script.
  • The locale parameter for each server is set to the same value.
  • openGauss users must be set during the preinstallation process.

Syntax

  • Install openGauss.

    gs_install -X XMLFILE [--gsinit-parameter="PARAMETER" [...]] [--dn-guc="PARAMETER" [...]] [--alarm-component=ALARMCOMPONENT] [--time-out=SECS] [-l LOGFILE]  
    

    NOTE:

  • Display help information.

    gs_install -? | --help
    
  • Display version information.

    gs_install -V | --version
    

Parameter Description

  • -X

    Specifies the path of the openGauss configuration file.

    Value range: storage paths of XML files

  • -l

    Specifies a log file and its path.

    When -l is not specified and gaussdbLogPath is not set in the XML file, the default value of the -l parameter is $GAUSSLOG/om/gs_install-YYYY-MM-DD_hhmmss.log.

    When -l is not specified but gaussdbLogPath is set in the XML file, the default value of the -l parameter is the combination value of gaussdbLogPath/User name/om/gs_install-YYYY-MM-DD_hhmmss.log.

  • --gsinit-parameter=PARAM

    Specifies the data instance parameters.

    For details about the value range, see parameter description in gs_initdb. Among which, the settings of the -A, -D, -U, -C, and -X parameters do not take effect.

  • --dn-guc=PARAM

    Set a parameter.

    For details about the value range, see parameter description in gs_guc.

  • --time-out=SECS

    Specifies the timeout threshold for startup. Unit: s

    If the value of --time-out is too small, the instance startup may time out due to a large number of instances. If the instance failed to be started within the specified timeout period, an error will be reported. openGauss still runs at the backend. You can wait for a while and then query the openGauss status to check whether openGauss is started successfully.

    Value range: a positive integer. If there is no special requirement, you do not need to set this parameter. The system automatically adjusts the timeout threshold.

  • --alarm-component=alarm_component

    Specifies the absolute path of the component to report alarms.

  • -?, --help

    Displays help information.

  • -V, --version

    Displays version information.
