Installation Using an RPM Package

This section describes how to install the openGauss database on openEuler 22.03 LTS by running the yum command.

Supported Architectures and OSs

This installation method is supported only on openEuler 22.03 LTS.

Currently, installing openGauss by running the yum command is only supported on openEuler 22.03 LTS and only the ARM64 and x86_64 architectures are supported.
The database integrated into the openEuler system is built based on the capabilities of the openGauss Lite edition.
Only a standalone database instance is installed by using an RPM package. To upgrade the database, you can only replace binary files. Gray upgrade is not supported.
By default, the IP address and port number 127.0.0.1:7654 of the installed database instance are used for listening. If remote connection is required, you need to manually change the value of listen_address in the postgresql.conf file.
The user openGauss is created by default during database installation and is not deleted after the database is uninstalled.

After the OS is installed, run the yum install command to install the database.
yum install opengauss -y
During the OS installation, set software to openGauss. The openGauss database is installed by default during the OS installation.

Run the su - opengauss command to switch to the user opengauss.
Run the ps ux command to check the process. The binary installation directory is /usr/local/opengauss, and the default startup data directory is /var/lib/opengauss/data.
Run the gsql -d postgres -p 7654 -r command to connect to the database. The default port number is 7654. After the database is connected, the database can be properly used.
