FAQ

How can I view the logs?

On macOS:

cat ~/.ollama/logs/server.log

On Linux:

journalctl -u ollama

If you're running ollama serve directly, the logs will be printed to the console.

How can I expose Ollama on my network?

Ollama binds to 127.0.0.1 port 11434 by default. Change the bind address with the OLLAMA_HOST environment variable.

On macOS:

OLLAMA_HOST=0.0.0.0:11435 ollama serve

On Linux:

Create a systemd drop-in directory and set Environment=OLLAMA_HOST

mkdir -p /etc/systemd/system/ollama.service.d
echo '[Service]' >>/etc/systemd/system/ollama.service.d/environment.conf

echo 'Environment="OLLAMA_HOST=0.0.0.0:11434"' >>/etc/systemd/system/ollama.service.d/environment.conf

Reload systemd and restart Ollama:

systemctl daemon-reload
systemctl restart ollama

How can I allow additional web origins to access Ollama?

Ollama allows cross origin requests from 127.0.0.1 and 0.0.0.0 by default. Add additional origins with the OLLAMA_ORIGINS environment variable:

On macOS:

OLLAMA_ORIGINS=http://192.168.1.1:*,https://example.com ollama serve

On Linux:

echo 'Environment="OLLAMA_ORIGINS=http://129.168.1.1:*,https://example.com"' >>/etc/systemd/system/ollama.service.d/environment.conf

Reload systemd and restart Ollama:

systemctl daemon-reload
systemctl restart ollama

Where are models stored?

• macOS: Raw model data is stored under ~/.ollama/models.
• Linux: Raw model data is stored under /usr/share/ollama/.ollama/models

Below the models directory you will find a structure similar to the following:

.
├── blobs
└── manifests
   └── registry.ollama.ai
      ├── f0rodo
      ├── library
      ├── mattw
      └── saikatkumardey

There is a manifests/registry.ollama.ai/namespace path. In example above, the user has downloaded models from the official library, f0rodo, mattw, and saikatkumardey namespaces. Within each of those directories, you will find directories for each of the models downloaded. And in there you will find a file name representing each tag. Each tag file is the manifest for the model.

The manifest lists all the layers used in this model. You will see a media type for each layer, along with a digest. That digest corresponds with a file in the models/blobs directory.

How can I change where Ollama stores models?

To modify where models are stored, you can use the OLLAMA_MODELS environment variable. Note that on Linux this means defining OLLAMA_MODELS in a drop-in /etc/systemd/system/ollama.service.d service file, reloading systemd, and restarting the ollama service.

Does Ollama send my prompts and answers back to Ollama.ai to use in any way?

No. Anything you do with Ollama, such as generate a response from the model, stays with you. We don't collect any data about how you use the model. You are always in control of your own data.

How can I use Ollama in Visual Studio Code?

There is already a large collection of plugins available for VSCode as well as other editors that leverage Ollama. You can see the list of extensions & plugins at the bottom of the main repository readme.

How do I use Ollama behind a proxy?

Ollama is compatible with proxy servers if HTTP_PROXY or HTTPS_PROXY are configured. When using either variables, ensure it is set where ollama serve can access the values.

When using HTTPS_PROXY, ensure the proxy certificate is installed as a system certificate.

On macOS:

HTTPS_PROXY=http://proxy.example.com ollama serve

On Linux:

echo 'Environment="HTTPS_PROXY=https://proxy.example.com"' >>/etc/systemd/system/ollama.service.d/environment.conf

Reload systemd and restart Ollama:

systemctl daemon-reload
systemctl restart ollama

How do I use Ollama behind a proxy in Docker?

The Ollama Docker container image can be configured to use a proxy by passing -e HTTPS_PROXY=https://proxy.example.com when starting the container.

Alternatively, Docker daemon can be configured to use a proxy. Instructions are available for Docker Desktop on macOS, Windows, and Linux, and Docker daemon with systemd.

Ensure the certificate is installed as a system certificate when using HTTPS. This may require a new Docker image when using a self-signed certificate.

FROM ollama/ollama
COPY my-ca.pem /usr/local/share/ca-certificates/my-ca.crt
RUN update-ca-certificates

Build and run this image:

docker build -t ollama-with-ca .
docker run -d -e HTTPS_PROXY=https://my.proxy.example.com -p 11434:11434 ollama-with-ca

How do I use Ollama with GPU acceleration in Docker?

The Ollama Docker container can be configured with GPU acceleration in Linux or Windows (with WSL2). This requires the nvidia-container-toolkit. See ollama/ollama for more details.

GPU acceleration is not available for Docker Desktop in macOS due to the lack of GPU passthrough and emulation.
