# 前置作業
###### tags: `TensorFlow`

## 一、Ubuntu SSH與防火牆設定

# 更新apt套件資訊
sudo apt-get update
sudo apt-get upgrade

# 安裝net-tools 才可使用ifconfig
sudo apt install net-tools

# 安裝ssh
sudo apt-get install -y openssh-server

# 查看ssh狀態
sudo systemctl status ssh.service

# 設定常駐ssh
sudo systemctl enable ssh.service

# 打開防火牆port8888 讓jupyter notebook或jupyter lab可以連進來
sudo ufw allow 8888

# 重啟防火牆生效設定
sudo systemctl restart ufw

## 二、Jupyter Notebook安裝及設定

# 安裝jupyter notebook
sudo apt-get install jupyter

# 建立jupyter notebook設定檔案
jupyter notebook --generate-config

# 修改jupyter notebook配置
sudo nano /home/[username]/.jupyter/jupyter_notebook_config.py
# 路徑的username要換成自己的

# 將設定檔案內的c.NotebookApp.ip由localhost改為對外開放
c.NotebookApp.ip = '0.0.0.0'
# 儲存後即可由windows連線

# 將設定檔案內的token和密碼要求拿掉
c.NotebookApp.token = ''
c.NotebookApp.password = ''
# 儲存後即可不用token和密碼即可直接連線jupyter notebook

# 啟用jupyter notebook
jupyter notebook

## 三、Jupyter Lab安裝及設定

# 安裝jupyter lab
sudo pip3 install jupyterlab   # 記得加sudo

# 產生jupyter lab設定檔案
jupyter-lab --generate-config  # 不要加sudo 若加sudo會將config存到root底下

# 修改jupyter lab配置
sudo nano /home/[username]/.jupyter/jupyter_lab_config.py
# 路徑的username要換成自己的

# 將設定檔案內的c.NotebookApp.ip由localhost改為對外開放
c.ServerApp.ip = '0.0.0.0'
# 儲存後即可由windows連線

# 將設定檔案內的token和密碼要求拿掉
c.ServerApp.token = ''
c.ServerApp.password = ''
# 儲存後即可不用token和密碼即可直接連線jupyter notebook

# 啟用jupyter lab
jupyter lab

## 四、將Jupyter Lab及Notebook在開機中常駐

# 先進到/etc/systemd/system 資料夾中
cd etc/systemd/system

# 新增一個jupyter-lab.service 檔案
sudo nano jupyter-lab.service
sudo nano jupyter.service # notebook

# 將下列程式碼貼入檔案中
[Unit]
After=network.service

[Service]
ExecStart=jupyter-lab # 若是notebook,就改成jupyter notebook 
User=<username> # 輸入自己的username

[Install]
WantedBy=default.target

# 設定常駐jupyter lab (notebook)
sudo systemctl enable jupyter-lab.service
sudo systemctl enable jupyter.service # notebook

# 開啟jupyter lab (notebook) 在背景執行
sudo systemctl start jupyter-lab.service
sudo systemctl start jupyter.service # notebook

# 查看jupyter lab (notebook) 使用狀態
sudo systemctl status jupyter-lab.service
sudo systemctl status jupyter.service # notebook

若有成功就會出現下列畫面

這樣下次開機後不用再用虛擬機開啟jupter lab後才能用本機端去連線!
