RPM and Tarball Install

Prerequisites

Download and install the required Java version.

RPM Installation

Perform these steps on each node of your Dremio cluster:

Download and install Dremio via RPM.
```
$ sudo yum install dremio-<VERSION>.rpm
```
(Optional) Enable dremio to start at boot.
```
$ sudo chkconfig --level 3456 dremio on
```
Configure Dremio. See Dremio Configuration for more information.

Default Configuration

The following configurations are created by default when you install Dremio using the RPM package.

Software/File	Location
Software location	/opt/dremio
dremio.conf configuration file	/etc/dremio/dremio.conf
dremio-env environment configuration file	/etc/dremio/dremio-env
Local path (for data location)	/var/lib/dremio
Log directory	/var/log/dremio
PID files directory	/var/run/dremio

Changing the Dremio User and Group

The generic installation steps assume a user called dremio.

To run the Dremio daemon service under a different username (for example, testuser), apply the following changes before configuring.

Update the DREMIO_USER in the /etc/sysconfig/dremio file to testuser.

Apply the following permissions:

sudo chown -R testuser:testuser /var/log/dremio
sudo chown -R testuser:testuser /var/lib/dremio
sudo chown -R testuser:testuser /var/run/dremio

Using a Tarball

Perform these steps on each node of your Dremio cluster:

Create a dremio group.
```
sudo groupadd -r dremio
```

Create a dremio user.

sudo useradd -r -g dremio -d /var/lib/dremio -s /sbin/nologin dremio

Create Dremio directories.

sudo mkdir /opt/dremio
sudo mkdir /var/run/dremio && sudo chown dremio:dremio /var/run/dremio
sudo mkdir /var/log/dremio && sudo chown dremio:dremio /var/log/dremio
sudo mkdir /var/lib/dremio && sudo chown dremio:dremio /var/lib/dremio

Unpack Dremio into the /opt/dremio directory.
```
sudo tar xvf dremio-enterprise-<VERSION>.tar.gz -C /opt/dremio --strip-components=1
```
note
For Community Edition, the Tarball package file name is dremio-community-<VERSION>.tar.gz.
Create a symbolic link for the configuration folder.
```
sudo ln -s /opt/dremio/conf /etc/dremio
```
(Optional) Set up your service configuration (SystemD setup).

a. Copy the unit file for the dremio daemon from <DREMIO_HOME>/share/dremio.service to /etc/systemd/system/dremio.service.
```
sudo cp <DREMIO_HOME>/share/dremio.service /etc/systemd/system/dremio.service
```
b. Restart systemd.
```
sudo systemctl daemon-reload
```
c. (Optional) Enable dremio to start at boot.
```
sudo systemctl enable dremio
```
Configure Dremio. See Dremio Configuration for more information.

Sample Service Configuration

The following snippet shows the configuration in the <DREMIO_HOME>/share/dremio.service file:

    #
    # Installation is assumed to be under /opt/dremio
    #
    [Unit]

    Group=dremio
    RuntimeDirectory=dremio
    ExecStart=/opt/dremio/bin/dremio start-fg
    Restart=on-failure
    # Set maximum number of file descriptors Dremio can open.
    # Dremio requires a large number to work correctly.
