Installation on a Single Node

1. Create a user group dbgroup.

    ""groupadd dbgroup
   

2. Create a common user omm in the dbgroup user group and set the password to Gauss_234.

    ""useradd -g dbgroup omm
    passwd Gauss_234
   

3. Log in to the host where the openGauss package is installed as user omm and decompress the openGauss package to the installation directory (for example, /opt/software/openGauss).

    ""tar -jxf openGauss-x.x.x-openEuler-64bit.tar.bz2 -C /opt/software/openGauss
   

4. Assume that the decompressed package is stored in the /opt/software/openGauss directory. Go to the simpleInstall directory.

    ""cd /opt/software/openGauss/simpleInstall
   

5. Run the install.sh script to install openGauss.

    ""sh install.sh  -w xxxx
   

   In the preceding command, -w indicates the initial database password (specified by gs_initdb). This parameter is mandatory for security purposes.

6. After the installation is complete, check whether the process is normal by using ps and gs_ctl.

    ""ps ux | grep gaussdb
    gs_ctl query -D /opt/software/openGauss/data/single_node
   

   Run the ps command to display information similar to the following:

    ""omm      24209 11.9  1.0 1852000 355816 pts/0  Sl   01:54   0:33 /opt/software/openGauss/bin/gaussdb -D /opt/software/openGauss/single_node
    omm      20377  0.0  0.0 119880  1216 pts/0    S+   15:37   0:00 grep --color=auto gaussdb
   

   Run the gs_ctl command to display information similar to the following:

    ""gs_ctl query ,datadir is /opt/software/openGauss/data/single_node
    HA state:
        local_role                     : Normal
        static_connections             : 0
        db_state                       : Normal
        detail_information             : Normal
   
    Senders info:
        No information
   
     Receiver info:
    No information
