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
