II. Configuration of environment variables

OllamaYou can install Ollama with one click on your computer like any other software, but it is recommended that you configure the system environment variables according to your actual needs. Below are the instructions for configuring environment variables for Ollama.

For beginners, we strongly recommend that you configure the OLLAMA_MODELS to change the model storage location. By default, Ollama models are stored in the user directory on the C drive under the .ollama/models folder, which takes up space on the C drive. Changing it to another partition will allow you to better manage your storage.

Step 1: Locate the entry point for setting system environment variables.

Method 1: Start->Settings->About->Advanced System Settings->System Properties->Environmental Variables.

Method 2: This computer -> Right click -> Properties -> Advanced System Settings -> Environment Variables.

Method 3: Start->Control Panel->System and Security->System->Advanced System Settings->System Properties->Environmental Variables.

Method 4: Win+R to open the Run window, enter sysdm.cpl, enter to open System Properties, select the Advanced tab, and click Environment Variables.

Step 2: Setup OLLAMA_MODELS Environment Variables (change the model storage location)

1. In " environment variable " Window's " System variables (S) " area (or the "User Variables (U)" area, depending on your needs), click the " new (W)... " button.
2. In " Variable name (N) " input box, type: OLLAMA_MODELS (Note the case, all capitalization is recommended).
3. In " Value of variable (V) " input box, enter the model storage path you want to set. For example, if you want to store the model on the E drive of the ollama\models folder, you can enter in the "Variable Value (V)": E:\ollama\models (Please modify the disk letter and folder path according to your actual situation).
   • Attention: Make sure you enter the path Already Existing Folders or The parent directory of the folder you wish to create exists . Ollama may be automatically created when it is first run models folder, but it's a good idea to create the ollama folder to make sure the path is correct.
   • Example: In order to store the model on the E-disk of the ollama\models folder, you can enter it in the "Variable Value (V)": E:\ollama\models
4. Click " recognize " button, close " New system variables " (or "New User Variable") window.

Attention: If you don't know how to set OLLAMA_MODELS environment variable, you can refer to the following example.

(Optional) Settings OLLAMA_HOST environment variable (modify the listening address).

If you need to make your Ollama service accessible to other devices on the LAN, you can configure the OLLAMA_HOST Environment variables.

1. Also in " environment variable " Window's " System variables (S) " area (or the "User Variables (U)" area), click the " new (W)... " button.
2. In " Variable name (N) " input box, type: OLLAMA_HOST
3. In " Value of variable (V) " input box, type 0.0.0.0:11434 (or the port number you want to specify; the default port is 11434).
   • 0.0.0.0 Indicates listening to all network interfaces to allow LAN access.
   • 11434 is the Ollama default port.
   • Example: 0.0.0.0:11434
4. Click " recognize " button, close " New system variables " (or "New User Variable") window.

Step 3: Restart Ollama or PowerShell to make the environment variables take effect
