免sudo安装Ollama

To install Ollama without using sudo, you can follow these steps to set it up in your user space. This approach allows you to avoid requiring administrative privileges, making it suitable for shared environments or systems where you do not have root access.

Installation Steps

1. Download the Ollama Binary
   Use curl to download the Ollama binary directly to your home directory or a preferred location where you have write access:

   curl -L https://ollama.com/download/ollama-linux-amd64.tgz -o ollama-linux-amd64.tgz
   

2. Create a Local Directory
   Create a directory in your home folder to store the Ollama files. This example uses ~/.local, but you can choose any directory where you have write permissions:

   mkdir -p ~/.local
   

3. Extract the Downloaded File
   Extract the downloaded .tgz file into the local directory:

   tar -C ~/.local -xzf ollama-linux-amd64.tgz
   

4. Update Your PATH
   To run Ollama from anywhere in your terminal, add the local binary directory to your PATH. You can do this by adding the following line to your shell configuration file (like ~/.bashrc or ~/.bash_profile):

   export PATH="$HOME/.local:$PATH"
   

   After editing the file, make sure to source it to apply the changes:

   source ~/.bashrc  # or source ~/.bash_profile
   

5. Run Ollama
   Now you should be able to run Ollama directly from the command line:

   ollama serve &
   

6. Verify Installation
   Check if Ollama is running correctly by executing:

   ollama --version
   

Additional Notes

• If you encounter any issues with running models, ensure that your environment variables are set correctly, particularly LD_LIBRARY_PATH, if required by any dependencies.
• For users interested in package management without root access, consider using tools like Nix, which allow for easy installation and management of packages in user space without needing sudo privileges[1][2].

By following these steps, you can successfully install and run Ollama on your Linux machine without needing administrative rights.
