How do I use Ollama server environment variables on Mac

On macOS, Ollama runs in the background and is managed by the menubar app. If adding environment variables, Ollama will need to be run manually.

1. Click the menubar icon for Ollama and choose Quit Ollama.

2. Open a new terminal window and run the following command (this example uses OLLAMA_HOST with an IP address of 123.1.1.1):

   OLLAMA_HOST=123.1.1.1 ollama serve
   

How do I use Ollama server environment variables on Linux?

If Ollama is installed with the install script, a systemd service was created, running as the Ollama user. To add an environment variable, such as OLLAMA_HOST, follow these steps:

1. Create a systemd drop-in directory and add a config file. This is only needed once.

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

2. For each environment variable, add it to the config file:

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

3. Reload systemd and restart Ollama:

   systemctl daemon-reload
   systemctl restart ollama
   

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. Refer to the section above for how to use environment variables on your platform.

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. For example, to add all ports on 192.168.1.1 and https://example.com, use:

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

Refer to the section above for how to use environment variables on your platform.

Where are models stored?

• macOS: ~/.ollama/models.
• Linux: /usr/share/ollama/.ollama/models

How do I set them to a different location?

If a different directory needs to be used, set the environment variable OLLAMA_MODELS to the chosen directory. Refer to the section above for how to use environment variables on your platform.

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

No, Ollama runs entirely locally, and conversation data will never leave your machine.

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. 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. Refer to the section above for how to use environment variables on your platform.

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, the 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.

Why is networking slow in WSL2 on Windows 10?

This can impact both installing Ollama, as well as downloading models.

Open Control Panel > Networking and Internet > View network status and tasks and click on Change adapter settings on the left panel. Find the vEthernel (WSL) adapter, right click and select Properties. Click on Configure and open the Advanced tab. Search through each of the properties until you find Large Send Offload Version 2 (IPv4) and Large Send Offload Version 2 (IPv6). Disable both of these properties.
