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
