CentOS7搭建Python3+JupyterNotebook遠程訪問環境

一.  配置准備：

• Oracle 雲服務賬號
• 雲主機一台：操作系統 CentOS7
• Xshell 連接
• Chrome 瀏覽器

二.  安裝步驟

1.  創建雲主機
   • 創建OCI虛擬網絡VCN
     新建VCN網絡：
     

     配置Security List（打開訪問端口即可）：
     

   • 創建計算實例
     

     

   • 通過Xshell連接到此實例
     

     並通過修改配置文件，允許root用戶的登錄。

2.  安裝Python3
   創建安裝目錄，下載 Python3.6.5 安裝包，並將壓縮包解壓到對應目錄中
   

   mkdir /opt/Python3
   cd /opt/Python3/
   wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
   tar -xvf Python-3.6.5.tgz
   ls -l

   

   安裝 Python3 依賴包

   yum -y install zlib zlib-devel
   yum -y install bzip2 bzip2-devel
   yum -y install ncurses ncurses-devel
   yum -y install readline readline-devel
   yum -y install openssl openssl-devel
   yum -y install openssl-static
   yum -y install xz lzma xz-devel
   yum -y install sqlite sqlite-devel
   yum -y install gdbm gdbm-devel
   yum -y install tk tk-devel
   yum -y install gcc

   配置Python安裝環境，並編譯、安裝Python3

   cd Python-3.6.5/
   ./configure --with-ssl --prefix=/opt/Python3
   make
   make install

   

   配置Python3環境變量

   [root@demo-instance ~]# vim ~/.bash_profile

   # .bash_profile

   # Get the aliases and functions
   if [ -f ~/.bashrc ]; then
   . ~/.bashrc
   fi

   # User specific environment and startup programs

   export python=/opt/Python3/bin

   PATH=$PATH:$HOME/bin:/opt/Python3/bin

   export PATH

   編輯關聯

   mv /usr/bin/python /usr/bin/python_bak
   ln -s /opt/Python3/bin/python3 /usr/bin/python
   3 ln -s /opt/Python3/bin/python3 /usr/bin/python3

   

   升級pip

   python -m pip install --upgrade pip

   

    

3.  安裝Jupyter Notebook
   通過pip安裝Jupyter Notebook
   

   python3 -m pip install jupyter
   2 ln -s /opt/Python3/bin/jupyter /usr/bin/jupyter

   通過jupyter notebook命令啟動Jupyter服務器，查看是否安裝成功

   [root@demo-instance Python-3.6.5]# jupyter notebook --allow-root
   [I 09:03:32.473 NotebookApp] Serving notebooks from local directory: /opt/Python3/Python-3.6.5
   [I 09:03:32.473 NotebookApp] The Jupyter Notebook is running at:
   [I 09:03:32.473 NotebookApp] http://localhost:8888/?token=9fb8cc50c87a1f5a35c2d57d0722dc1c0f58f5be892a6532
   [I 09:03:32.473 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
   [W 09:03:32.479 NotebookApp] No web browser found: could not locate runnable browser.
   [C 09:03:32.479 NotebookApp] 
       
       To access the notebook, open this file in a browser:
           file:///root/.local/share/jupyter/runtime/nbserver-24125-open.html
       Or copy and paste one of these URLs:
           http://localhost:8888/?token=9fb8cc50c87a1f5a35c2d57d0722dc1c0f58f5be892a6532

   至此，Jupyter Notebook安裝成功。
   
   

4.  配置外部訪問
   關閉防火牆（CentOS7）
   

   systemctl stop firewalld.service
   systemctl disable firewalld.service 

   生成Jupyter Notebook配置文件

   jupyter notebook --generate-config

   

   通過 ipython 創建登錄密碼：

   

   編輯生成的配置文件 /root/.jupyter/jupyter_notebook_config.py，並在文件頭添加如下配置信息：

   c.NotebookApp.ip='0.0.0.0' # 就是設置所有ip皆可訪問
   c.NotebookApp.password = u'sha1:7b115a66b162:e6bc039abf83eab1947dd9445d9fe408c659e3d2' #前邊保存的密碼信息
   c.NotebookApp.open_browser = False #禁止自動打開瀏覽器
   c.NotebookApp.port =8888 #隨便指定一個端口，默認為8888

   

   先 reboot 機器，然后使用命令 jupyter nodebook 啟動服務器

   

   通過瀏覽器訪問地址：http://ipaddress:8888/
   

   輸入創建的密碼，即可登錄Jupyter Notebook的工作區：
