OpenGauss community released openGauss 2.0 recently, with this release, they provide a simplified package with official supporting Centos and OpenEuler. I tried the OpenEuler version on Debian 10 with success, the step is:
1 Download opengauss and unzip to destination folder;
2 Setting enviroment: add $GAUSSHOME, append $GAUSSHOE/bin to $PATH, and $GAUSSHOE/lib to $LD_LIBRARY_PATH;
3 run gs_initdb to test which libs are lack, install them;
4 run gs_initdb to init the database;
5 run gs_ctl to start the database;
6 run gsql to create and grant a login user (initial user is not allowed to login)
7 test connecton and more setting such as remote access. more.
8 create a systemd service:
(1) In /etc/ld.so.conf.d/ create opengauss.conf, add one line in it : /opt/opengauss/lib
(2) download "opengauss.service" put it into /usr/lib/systemd/system/
run : sudo systemctl enable opengauss
and : sudo systemctl start opengauss
process noted as:
user@debian:~$ echo $PATH
/home/user/bin:/opt/opengauss/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
user@debian:~$ echo $LD_LIBRARY_PATH
/opt/opengauss/lib:
user@debian:~$ cd $GAUSSHOME
user@debian:/opt/opengauss$ pwd
/opt/opengauss
user@debian:/opt/opengauss$ gs_initdb -w password -D $GAUSSHOME/data/gsdb --nodename "sgnode" --locale="en_US.UTF-8"
/opt/opengauss/bin/gaussdb: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
no data was returned by command ""/opt/opengauss/bin/gaussdb" -V"
The program "gaussdb" is needed by gs_initdb but was not found in the
same directory as "/opt/opengauss/bin/gs_initdb".
Check your installation.

The files belonging to this database system will be owned by user "user".
This user must also own the server process.
The database cluster will be initialized with locale "en_US.UTF-8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run gs_initdb.
Success. You can now start the database server of single node using:
gaussdb -D /opt/opengauss/data/gsdb --single_node
or
gs_ctl start -D /opt/opengauss/data/gsdb -Z single_node -l logfile
user@debian:/opt/opengauss$ gs_ctl start -D /opt/opengauss/data/gsdb -Z single_node -l logfile

1 Download libpq-og.dll from this repo;
2 Download HeidiSQL;
3 Put libpq-og.dll into HeidiSQL home folder;
4 Start HeidiSQL configuration with libpq-og.dll
5 enjoy
