After you [plan your deployment]({{< relref "/operate/rs/installing-upgrading/install/plan-deployment" >}}), [download a Redis Software installation package]({{< relref "/operate/rs/installing-upgrading/install/prepare-install/download-install-package" >}}), and finish [installation preparation]({{< relref "/operate/rs/installing-upgrading/install/prepare-install" >}}):

1. [Install the Redis Software package]({{< relref "/operate/rs/installing-upgrading/install/install-on-linux" >}}) on one of the nodes in the cluster.

2. Repeat this process for each node in the cluster.

For installation on machines without an internet connection, see [Offline installation]({{< relref "/operate/rs/installing-upgrading/install/offline-installation" >}}).

Permissions and access

• Redis Software installation creates the redislabs:redislabs user and group.

  Assigning other users to the redislabs group is optional. Users belonging to the redislabs group have permission to read and execute (e.g. use the rladmin status command) but are not allowed to write (or delete) files or directories.

• Redis Software is certified to run with permissions set to 750, an industry standard.

  {{<warning>}} Do not reduce permissions to 700. This configuration has not been tested and is not supported. {{</warning>}}

• Redis Software requires umask to be 0022 during installation to correctly set permissions for the installed directories and files.

More info and options

If you've already installed Redis Software, you can also:

• [Upgrade an existing deployment]({{< relref "/operate/rs/installing-upgrading/upgrading" >}}).

• [Uninstall an existing deployment]({{< relref "/operate/rs/installing-upgrading/uninstalling.md" >}}).

Next steps

After your cluster is set up with nodes, you can:

• [Add users]({{< relref "/operate/rs/security/access-control/create-users" >}}) to the cluster with specific permissions. To begin, start with [Access control]({{< relref "/operate/rs/security/access-control" >}}).
• [Create databases]({{< relref "/operate/rs/databases/create" >}}) to use with your applications.
