The problem with default.target is that it always points to the target that is currently started. So if you boot into single user mode or the rescue mode still Ollama tries to start. I noticed this because either tried (and failed) to start all the time during a system update, where Ollama definitely is not wanted.

## Install
|
|
|
|
To install Ollama, run the following command:
|
|
|
|
```shell
|
|
curl -fsSL https://ollama.com/install.sh | sh
|
|
```
|
|
|
|
## Manual install
|
|
|
|
> [!NOTE]
|
|
> If you are upgrading from a prior version, you should remove the old libraries with `sudo rm -rf /usr/lib/ollama` first.
|
|
|
|
Download and extract the package:
|
|
|
|
```shell
|
|
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:
|
|
|
|
```shell
|
|
ollama serve
|
|
```
|
|
|
|
In another terminal, verify that Ollama is running:
|
|
|
|
```shell
|
|
ollama -v
|
|
```
|
|
|
|
### AMD GPU install
|
|
|
|
If you have an AMD GPU, also download and extract the additional ROCm package:
|
|
|
|
```shell
|
|
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
|
|
```
|
|
|
|
### ARM64 install
|
|
|
|
Download and extract the ARM64-specific package:
|
|
|
|
```shell
|
|
curl -L https://ollama.com/download/ollama-linux-arm64.tgz -o ollama-linux-arm64.tgz
|
|
sudo tar -C /usr -xzf ollama-linux-arm64.tgz
|
|
```
|
|
|
|
### Adding Ollama as a startup service (recommended)
|
|
|
|
Create a user and group for Ollama:
|
|
|
|
```shell
|
|
sudo useradd -r -s /bin/false -U -m -d /usr/share/ollama ollama
|
|
sudo usermod -a -G ollama $(whoami)
|
|
```
|
|
|
|
Create a service file in `/etc/systemd/system/ollama.service`:
|
|
|
|
```ini
|
|
[Unit]
|
|
Description=Ollama Service
|
|
After=network-online.target
|
|
|
|
[Service]
|
|
ExecStart=/usr/bin/ollama serve
|
|
User=ollama
|
|
Group=ollama
|
|
Restart=always
|
|
RestartSec=3
|
|
Environment="PATH=$PATH"
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target
|
|
```
|
|
|
|
Then start the service:
|
|
|
|
```shell
|
|
sudo systemctl daemon-reload
|
|
sudo systemctl enable ollama
|
|
```
|
|
|
|
### Install CUDA drivers (optional)
|
|
|
|
[Download and install](https://developer.nvidia.com/cuda-downloads) CUDA.
|
|
|
|
Verify that the drivers are installed by running the following command, which should print details about your GPU:
|
|
|
|
```shell
|
|
nvidia-smi
|
|
```
|
|
|
|
### Install AMD ROCm drivers (optional)
|
|
|
|
[Download and Install](https://rocm.docs.amd.com/projects/install-on-linux/en/latest/tutorial/quick-start.html) ROCm v6.
|
|
|
|
### Start Ollama
|
|
|
|
Start Ollama and verify it is running:
|
|
|
|
```shell
|
|
sudo systemctl start ollama
|
|
sudo systemctl status ollama
|
|
```
|
|
|
|
> [!NOTE]
|
|
> 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.
|
|
|
|
## Customizing
|
|
|
|
To customize the installation of Ollama, you can edit the systemd service file or the environment variables by running:
|
|
|
|
```shell
|
|
sudo systemctl edit ollama
|
|
```
|
|
|
|
Alternatively, create an override file manually in `/etc/systemd/system/ollama.service.d/override.conf`:
|
|
|
|
```ini
|
|
[Service]
|
|
Environment="OLLAMA_DEBUG=1"
|
|
```
|
|
|
|
## Updating
|
|
|
|
Update Ollama by running the install script again:
|
|
|
|
```shell
|
|
curl -fsSL https://ollama.com/install.sh | sh
|
|
```
|
|
|
|
Or by re-downloading Ollama:
|
|
|
|
```shell
|
|
curl -L https://ollama.com/download/ollama-linux-amd64.tgz -o ollama-linux-amd64.tgz
|
|
sudo tar -C /usr -xzf ollama-linux-amd64.tgz
|
|
```
|
|
|
|
## Installing specific versions
|
|
|
|
Use `OLLAMA_VERSION` environment variable with the install script to install a specific version of Ollama, including pre-releases. You can find the version numbers in the [releases page](https://github.com/ollama/ollama/releases).
|
|
|
|
For example:
|
|
|
|
```shell
|
|
curl -fsSL https://ollama.com/install.sh | OLLAMA_VERSION=0.5.7 sh
|
|
```
|
|
|
|
## Viewing logs
|
|
|
|
To view logs of Ollama running as a startup service, run:
|
|
|
|
```shell
|
|
journalctl -e -u ollama
|
|
```
|
|
|
|
## Uninstall
|
|
|
|
Remove the ollama service:
|
|
|
|
```shell
|
|
sudo systemctl stop ollama
|
|
sudo systemctl disable ollama
|
|
sudo rm /etc/systemd/system/ollama.service
|
|
```
|
|
|
|
Remove the ollama binary from your bin directory (either `/usr/local/bin`, `/usr/bin`, or `/bin`):
|
|
|
|
```shell
|
|
sudo rm $(which ollama)
|
|
```
|
|
|
|
Remove the downloaded models and Ollama service user and group:
|
|
|
|
```shell
|
|
sudo rm -r /usr/share/ollama
|
|
sudo userdel ollama
|
|
sudo groupdel ollama
|
|
```
|
|
|
|
Remove installed libraries:
|
|
|
|
```shell
|
|
sudo rm -rf /usr/local/lib/ollama
|
|
```
