curl -L https://ollama.com/download/ollama-linux-amd64.tgz -o ollama-linux-amd64.tgz
sudo tar -C /usr -xzf ollama-linux-amd64.tgz
Start Ollama: 
ollama serve
In another terminal, verify that Ollama is running: 
ollama -v

​
AMD GPU install

If you have an AMD GPU, also download and extract the additional ROCm package: 
curl -L https://ollama.com/download/ollama-linux-amd64-rocm.tgz -o ollama-linux-amd64-rocm.tgz
sudo tar -C /usr -xzf ollama-linux-amd64-rocm.tgz

​

curl -L https://ollama.com/download/ollama-linux-arm64.tgz -o ollama-linux-arm64.tgz
sudo tar -C /usr -xzf ollama-linux-arm64.tgz
Create a user and group for Ollama: 
sudo useradd -r -s /bin/false -U -m -d /usr/share/ollama ollama
sudo usermod -a -G ollama $(whoami)
Create a service file in /etc/systemd/system/ollama.service: 
[Unit]
Description=Ollama Service
After=network-online.target

[Service]
ExecStart=/usr/bin/ollama serve
User=ollama
Group=ollama
Restart=always
RestartSec=3
Environment="PATH=$PATH"

[Install]
WantedBy=multi-user.target
Then start the service: 
sudo systemctl daemon-reload
sudo systemctl enable ollama

​
Install CUDA drivers (optional)

Download and install CUDA. Verify that the drivers are installed by running the following command, which should print details about your GPU: 
nvidia-smi

​
Install AMD ROCm drivers (optional)

Download and Install ROCm v6.

​
Start Ollama

Start Ollama and verify it is running: 
sudo systemctl start ollama
sudo systemctl status ollama
While AMD has contributed the amdgpu driver upstream to the official linux kernel source, the version is older and may not support all ROCm features. We recommend you install the latest driver from https://www.amd.com/en/support/linux-drivers for best support of your Radeon GPU.

​

[Service]
