之前配过一次centos7+python3.10.6，但是python3.10.6里没有ssl，这个弄了好久没成功，不知道哪里不对，用了python3.9.6版本就可以了，记录下。

配置文件

文件夹下就是这些了，Dockerfile就是docker的构建文件，requirements.txt就是python依赖的第三方库，最后.tar.xz就是Python-3.9.6了，也可以进去下载，不过在这下好了，里面就快了。

Dockerfile文件内容如下

FROM centos:7

#  yum 更新
RUN set -ex \
	&& yum -y install zlib-devel bzip2-devel libffi-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make wget \
	&& yum clean all \
	&& mkdir /usr/local/python \
	&& mkdir /home/data

#   复制所有文件 当前目录
COPY .  /home/data

RUN set -ex \
	&& cd /home/data \
	&& tar -xvJf  Python-3.9.6.tar.xz \
	&& cd Python-3.9.6 \
	&& ./configure prefix=/usr/local/python \
	&& make && make install \
	&& yum install -y epel-release \
        && yum install -y python-pip \
	&& rm -f /usr/bin/python \
	&& rm -f /usr/bin/pip \
	&& ln -s /usr/local/python/bin/python3 /usr/bin/python \
	&& ln -s /usr/local/python/bin/pip3 /usr/bin/pip

# 修复因修改python版本导致yum失效问题
RUN set -ex \
    && sed -i "s#/usr/bin/python#/usr/bin/python2.7#" /usr/bin/yum \
    && sed -i "s#/usr/bin/python#/usr/bin/python2.7#" /usr/libexec/urlgrabber-ext-down \
    && yum install -y deltarpm

# 安装python
RUN set -ex \
	&& python -V \
	&& python -m pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --upgrade pip

# # 安装yum 工具
RUN set -ex \
 	&& yum  install -y lrzsz \
	&& yum  install -y net-tools \
 	&& yum  install -y git \
 	&& yum  install -y zip unzip 

# 启动配置
RUN set -ex \
	&& cd /home \
 	&& pip list \
	&& echo "构建成功"

要是docker慢的话，可以把国内的一些源加进去。

docker构建以及自定义

build

docker build -t demo_p:v1 .

run

经过这一步会多一个镜像，运行

docker run -itd --name centos-test demo_p:v1

exec

进去容器

docker exec -it centos-test /bin/bash

查看信息

[root@3fb71a49165c /]# cat /etc/redhat-release

自定义

刚刚 requirements.txt在home/data下

pip install --upgrade pip  -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com
cd home/data
pip install -r requirements.txt  -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

下载jupyter

需要有–user

pip install jupyter  -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com --force-reinstall --user

下载的时候会报这个警告，就是说没有在环境变量里。

 The scripts jupyter-bundlerextension, jupyter-nbextension, jupyter-notebook and jupyter-serverextension are installed in '/root/.local/bin' which is not on PATH.

也会发现jupyter没有加进环境变量，找不到这个命令。

[root@3fb71a49165c data]# jupyter
bash: jupyter: command not found

配置环境变量

添加一下系统变量即可。

打开，插入，刷新

vim /etc/profile

export PATH=/root/.local/bin:${PATH}

source /etc/profile

这下就有了

[root@bdeec8d5baea /]# jupyter notebook
[C 11:27:56.941 NotebookApp] Running as root is not recommended. Use --allow-root to bypass.

将刷新的语句，存在启动里，要不每次进来容器都要刷一次，麻烦。

sudo vi ~/.bashrc

在最后添加

source /etc/profile

就OK了。

导出包

docker commit 3fb71a49165c hahaha:v2

看下镜像

(base) 192:docker_p Hekai$ docker images
REPOSITORY   TAG       IMAGE ID       CREATED              SIZE
hahaha       v2        2001e99e0378   About a minute ago   4.31GB
demo_p       v1        91d6b1aac935   4 hours ago          1.51GB

运行

其中/Users/Hekai/Desktop可替换为本地路径

docker run -it -p 8888:8888 -v /Users/Hekai/Desktop:/workspace  hahaha:v2 /bin/bash

再在容器里键入

jupyter notebook --ip 0.0.0.0 --allow-root

[root@2c63de413d84 /]# jupyter notebook --ip 0.0.0.0 --allow-root
[I 11:39:52.251 NotebookApp] Serving notebooks from local directory: /

    Or copy and paste one of these URLs:

     or http://127.0.0.1:8888/?token=fa79fcfc321957887ecd25752ce99daf320caf0327cdaf1c

链接也给出了，复制一个去浏览器就可以了，目录下面有个workspace，就是咱们本地路径了。

就酱。
