# Customize system user and group By default, Redis Enterprise Software is installed with the user:group `redislabs:redislabs`. During installation, you can specify the user and group that own all Redis Enterprise Software processes. ## Considerations - Custom installation user is supported on Red Hat Enterprise Linux. - You must create the user and group before installing Redis Enterprise Software. - You must install Redis Enterprise Software on all nodes in the cluster with the same user and group. - You can specify an LDAP user as the installation user. - If you specify the user only, then installation is run with the primary group that the user belongs to. ## Install with custom user or group To customize the user or group during [installation](http://redis.io/docs/latest/operate/rs/installing-upgrading/install/install-on-linux), include the `--os-user` or `--os-group` [command-line options](http://redis.io/docs/latest/operate/rs/installing-upgrading/install/install-script) when you run the `install.sh` script. ```sh sudo ./install.sh --os-user --os-group ```
