CentOS7搭建Python3+JupyterNotebook远程访问环境

2019-3-17

一. 配置准备：

Oracle 云服务账号
云主机一台：操作系统 CentOS7
Xshell 连接
Chrome 浏览器

二. 安装步骤

创建云主机
- 创建OCI虚拟网络VCN
  新建VCN网络：
  配置Security List（打开访问端口即可）：
- 创建计算实例
- 通过Xshell连接到此实例
  并通过修改配置文件，允许root用户的登录。

安装Python3
创建安装目录，下载 Python3.6.5 安装包，并将压缩包解压到对应目录中

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

安装 Python3 依赖包

 1 yum -y install zlib zlib-devel
 2 yum -y install bzip2 bzip2-devel
 3 yum -y install ncurses ncurses-devel
 4 yum -y install readline readline-devel
 5 yum -y install openssl openssl-devel
 6 yum -y install openssl-static
 7 yum -y install xz lzma xz-devel
 8 yum -y install sqlite sqlite-devel
 9 yum -y install gdbm gdbm-devel
10 yum -y install tk tk-devel
11 yum -y install gcc

配置Python安装环境，并编译、安装Python3

1 cd Python-3.6.5/
2 ./configure --with-ssl --prefix=/opt/Python3
3 make
4 make install

配置Python3环境变量

1 [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

编辑关联

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

升级pip

1 python -m pip install --upgrade pip

安装Jupyter Notebook
通过pip安装Jupyter Notebook

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

通过jupyter notebook命令启动Jupyter服务器，查看是否安装成功

 1 [root@demo-instance Python-3.6.5]# jupyter notebook --allow-root
 2 [I 09:03:32.473 NotebookApp] Serving notebooks from local directory: /opt/Python3/Python-3.6.5
 3 [I 09:03:32.473 NotebookApp] The Jupyter Notebook is running at:
 4 [I 09:03:32.473 NotebookApp] http://localhost:8888/?token=9fb8cc50c87a1f5a35c2d57d0722dc1c0f58f5be892a6532
 5 [I 09:03:32.473 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
 6 [W 09:03:32.479 NotebookApp] No web browser found: could not locate runnable browser.
 7 [C 09:03:32.479 NotebookApp] 
 8     
 9     To access the notebook, open this file in a browser:
10         file:///root/.local/share/jupyter/runtime/nbserver-24125-open.html
11     Or copy and paste one of these URLs:
12         http://localhost:8888/?token=9fb8cc50c87a1f5a35c2d57d0722dc1c0f58f5be892a6532

至此，Jupyter Notebook安装成功。

配置外部访问
关闭防火墙（CentOS7）

1 systemctl stop firewalld.service
2 systemctl disable firewalld.service

生成Jupyter Notebook配置文件

1 jupyter notebook --generate-config

通过 ipython 创建登录密码：

编辑生成的配置文件 /root/.jupyter/jupyter_notebook_config.py，并在文件头添加如下配置信息：

c.NotebookApp.ip='0.0.0.0'  # 就是设置所有ip皆可访问
c.NotebookApp.password = u'sha1:7b115a66b162:e6bc039abf83eab1947dd9445d9fe408c659e3d2' #前边保存的密码信息
c.NotebookApp.open_browser = False #禁止自动打开浏览器
c.NotebookApp.port =8888 #随便指定一个端口，默认为8888
