After executing the `userdel ollama` command, I saw this message: ```sh $ sudo userdel ollama userdel: group ollama not removed because it has other members. ``` Which reminded me that I had to remove the dangling group too. For completeness, the uninstall instructions should do this too. Thanks!

# Ollama on Linux
|
||
|
||
## Install
|
||
|
||
Install Ollama running this one-liner:
|
||
>
|
||
```bash
|
||
curl https://ollama.ai/install.sh | sh
|
||
```
|
||
|
||
## Manual install
|
||
|
||
### Download the `ollama` binary
|
||
|
||
Ollama is distributed as a self-contained binary. Download it to a directory in your PATH:
|
||
|
||
```bash
|
||
sudo curl -L https://ollama.ai/download/ollama-linux-amd64 -o /usr/bin/ollama
|
||
sudo chmod +x /usr/bin/ollama
|
||
```
|
||
|
||
### Adding Ollama as a startup service (recommended)
|
||
|
||
Create a user for Ollama:
|
||
|
||
```bash
|
||
sudo useradd -r -s /bin/false -m -d /usr/share/ollama ollama
|
||
```
|
||
|
||
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
|
||
|
||
[Install]
|
||
WantedBy=default.target
|
||
```
|
||
|
||
Then start the service:
|
||
|
||
```bash
|
||
sudo systemctl daemon-reload
|
||
sudo systemctl enable ollama
|
||
```
|
||
|
||
### Install CUDA drivers (optional – for Nvidia GPUs)
|
||
|
||
[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:
|
||
|
||
```bash
|
||
nvidia-smi
|
||
```
|
||
|
||
### Start Ollama
|
||
|
||
Start Ollama using `systemd`:
|
||
|
||
```bash
|
||
sudo systemctl start ollama
|
||
```
|
||
|
||
## Update
|
||
|
||
Update ollama by running the install script again:
|
||
|
||
```bash
|
||
curl https://ollama.ai/install.sh | sh
|
||
```
|
||
|
||
Or by downloading the ollama binary:
|
||
|
||
```bash
|
||
sudo curl -L https://ollama.ai/download/ollama-linux-amd64 -o /usr/bin/ollama
|
||
sudo chmod +x /usr/bin/ollama
|
||
```
|
||
|
||
## Viewing logs
|
||
|
||
To view logs of Ollama running as a startup service, run:
|
||
|
||
```bash
|
||
journalctl -u ollama
|
||
```
|
||
|
||
## Uninstall
|
||
|
||
Remove the ollama service:
|
||
|
||
```bash
|
||
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`):
|
||
|
||
```bash
|
||
sudo rm $(which ollama)
|
||
```
|
||
|
||
Remove the downloaded models and Ollama service user and group:
|
||
```bash
|
||
sudo rm -r /usr/share/ollama
|
||
sudo userdel ollama
|
||
sudo groupdel ollama
|
||
```
