## Considerations

- When you install with custom directories, the installation does not run as an RPM file.

- If a `redislabs` directory already exists in the path that you specify, the installation fails.

- All nodes in a cluster must be installed with the same file locations.

- Custom installation directories are not supported for databases using Auto Tiering.

## Configure different mount points for data and log directories {#config-diff-data-log-dirs}

To configure different mount points for data and log directories, use symbolic links:

1. Create a symbolic link for the data directory:

```sh
ln -s </path/to/data/mount/point> /var/opt/redislabs/data
```

1. Create a symbolic link for the log directory:

```sh
ln -s </path/to/log/mount/point> /var/opt/redislabs/log
```

## Limitations

Several Redis Enterprise Software installation reference files are installed to the directory `/etc/opt/redislabs/` even if you use custom installation directories.

- By default, the installation process requires an internet connection to install dependencies and synchronize the operating system clock. To learn more, see [Offline installation]({{< relref "/operate/rs/installing-upgrading/install/offline-installation" >}}).
