# Install New GPU Server Environment
###### tags: `BO`
## OS (ubuntu 18.04)
You know how to do. Borrow ubuntu USB from James.

## GPU Driver
Take `NVIDIA-Linux-x86_64-450.57` for example
+ download from: https://www.nvidia.com.tw/Download/index.aspx?lang=tw
+ switch to terminal mode: `ctrl+alt+F3`
+ turn off UI by `sudo service lightdm stop`
+ set it executable: `chmod +x NVIDIA-Linux-x86_64-450.57.run`
+ install: `sudo ./NVIDIA-Linux-x86_64-450.57.run`
+ <font color=red>google all errors</font>
+ reboot computer: `sudo reboot`
+ check install successed: `nvidia-smi`, output should look like
## Nvidia Docker Runtime
+ follow the steps to install Docker-CE from [here](https://docs.docker.com/v17.09/engine/installation/linux/docker-ce/ubuntu/).

    $ sudo apt-get remove docker docker-engine docker.io containerd runc
    $ sudo apt-get update
    $ sudo apt-get install \
        apt-transport-https \
        ca-certificates \
        curl \
        gnupg-agent \
        software-properties-common
    $ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

    # verify
    $ sudo apt-key fingerprint 0EBFCD88

    $ sudo add-apt-repository \
       "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
       $(lsb_release -cs) \
       stable"
    $ sudo apt-get update
    $ sudo apt-get install docker-ce docker-ce-cli containerd.io

    # verify
    $ sudo docker run hello-world
        

+ follow [here](https://github.com/NVIDIA/nvidia-docker) to install nvidia docker runtime

    $ distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
    $ curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
    $ curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list

    $ sudo apt-get update && sudo apt-get install -y nvidia-container-toolkit
    $ sudo systemctl restart docker

+ verify:
+ start an L1 container and type `nvidia-smi` inside it. You should get gpu info if nvidia docker runtime installed successfully.

## FAQ

### `An NVIDIA kernel module 'nvidia-drm' appears to already be loaded in your kernel`
+ If facing the error above while sudo `./NVIDIA-Linux-x86_64-460.84.run`, then refer to the second solution of [this](https://clay-atlas.com/blog/2020/03/04/nvidia-chinese-note-how-to-disable-drm/)

$ sudo -i
$ systemctl isolate multi-user.target
$ modprobe -r nvidia-drm
