#### 前置准备 ####

# 获取最新的软件包
    apt-get update
    
    # 升级已安装的软件包
    apt-get upgrade
    
    # 提前安装，以便接下来的配置操作
    apt-get -y install gcc automake autoconf libtool make
    apt-get -y install make*
    apt-get -y install zlib*
    apt-get -y install openssl libssl-dev
    apt-get install sudo

### 安装 Python 环境 ###

#### 下载 python ####

cd /usr/local/src
    wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz
    tar -zxvf Python-3.6.8.tgz
    mv Python-3.6.8 py3.6
    cd py3.6

#### make 编译安装 ####

在 /usr/local/src/py3.6 安装目录下执行下面的命令

./configure --prefix=/usr/local/src/py3.6
    make && make install

#### 添加软链接 ####

##### 添加 python3 软链接 #####

ln -s /usr/local/src/py3.6/bin/python3.6 /usr/bin/python3

##### 添加pip3软链接 #####

ln -s /usr/local/src/py3.6/bin/pip3 /usr/bin/pip3

本身有的话忽略就行

#### 验证 python3 环境 ####

敲 python3 和 pip3 有下图的结果就是正常了

#### 安装项目所需的库 ####

##### 首先 #####

需要在 python 项目生成一个 requirement.txt，具体教程可以看

[https://www.cnblogs.com/poloyy/p/13953232.html][https_www.cnblogs.com_poloyy_p_13953232.html]

##### 然后 #####

*  将 requirement.txt 上传到主机
 *  从主机复制到容器内 docker cp requirement.txt jenkins1:/usr/local/src

[![1c16dd9997c1c2ddcbdb0421cd86fde6.png][]][1c16dd9997c1c2ddcbdb0421cd86fde6.png 1]

##### 最后安装项目所需的库 #####

pip3 install -r requirements.txt

### 安装 Allure 环境 ###

#### 官网下载 allure 包 ####

[https://github.com/allure-framework/allure2/releases][https_github.com_allure-framework_allure2_releases]

[![dc437032242dc723a1608889ad18529c.png][]][dc437032242dc723a1608889ad18529c.png 1]

选个最新版本的去下就行，或者自己挑一个版本

#### 将压缩包传送到容器内 ####

1.  先将包上传到主机
2.  然后从主机复制到容器内

docker cp allure-commandline-2.13.6.zip jenkins1:/usr/local/src

#### 解压包 ####

unzip allure-commandline-2.13.6.zip

#### 赋予文件夹所有内容最高权限 ####

mv allure-2.13.6 allure
    chmod -R 777 allure

#### 配置 allure 和 py 环境变量 ####

cat >> /root/.bashrc << "EOF" 
    export PATH=/usr/local/src/allure/bin:$PATH 
    export PATH=/usr/local/src/py3.6/bin:$PATH 
    EOF

记得一行一个回车哦，不然就直接复制粘贴

##### 更新环境变量配置文件 #####

source /root/.bashrc

#### 验证环境变量 ####

allure --version
    python3 --version

### 配置 JDK 环境变量 ###

#### 查看当前的系统已配置的环境变量 ####

export

[![dfaa8712df1fedcb13caae2183512513.png][]][dfaa8712df1fedcb13caae2183512513.png 1]

这里可以看到很多容器本身自带的环境变量

*  Jenkins 的版本
 *  JDK 的安装路径

#### 配置 JDK 环境变量 ####

cat >> /root/.bashrc<< "EOF" 
    export PATH=$JAVA_HOME/bin:$PATH 
    EOF

##### 更新环境变量配置文件 #####

source /root/.bashrc

==========================================================

## 进jenkins容器 ##

进docker容器, 加上-u root 以root用户权限进入容器

> docker exec -it -u root 容器id /bin/bash

查看当前操作系统`cat /etc/issue`

root@cb8e397d5308:/# uname -a
    Linux cb8e397d5308 3.10.0-957.21.3.el7.x86_64 #1 SMP Tue Jun 18 16:35:19 UTC 2019 x86_64 GNU/Linux root@cb8e397d5308:/# cat /etc/issue Debian GNU/Linux 9 \n \l

这里查到的是Debian系统(不是ubuntu， 也不是centos)，这里yum是没有的，所以不能用yum安装了，这里用apt-get代替yum  
先执行更新apt-get

> apt-get update

## 容器内部安装python3环境 ##

#### 下载python3安装包 ####

进入容器内部, linux安装python3环境,参考这篇[https://www.cnblogs.com/yoyoketang/p/10195102.html][https_www.cnblogs.com_yoyoketang_p_10195102.html]

root@cb8e397d5308:/var/jenkins_home# cd /var/jenkins_home/
    root@cb8e397d5308:/var/jenkins_home# mkdir python3 root@cb8e397d5308:/var/jenkins_home# cd python3/ root@cb8e397d5308:/var/jenkins_home/python3# wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz root@cb8e397d5308:/var/jenkins_home/python3# tar -xvf Python-3.6.8.tgz root@cb8e397d5308:/var/jenkins_home/python3# ls Python-3.6.8 Python-3.6.8.tgz root@cb8e397d5308:/var/jenkins_home/python3# cd Python-3.6.8 root@cb8e397d5308:/var/jenkins_home/python3/Python-3.6.8# ./configure --prefix=/var/jenkins_home/python3 checking build system type... x86_64-pc-linux-gnu checking host system type... x86_64-pc-linux-gnu checking for python3.6... no checking for python3... no checking for python... python checking for --enable-universalsdk... no checking for --with-universal-archs... no checking MACHDEP... linux checking for --without-gcc... no checking for --with-icc... no checking for gcc... no checking for cc... no checking for cl.exe... no configure: error: in `/var/jenkins_home/python3/Python-3.6.8': configure: error: no acceptable C compiler found in $PATH See `config.log' for more details

执行 `./configure --prefix=/var/jenkins_home/python3`时报上面错：configure: error: no acceptable C compiler found in $PATH

#### apt-get 安装依赖包 ####

这个是因为缺少gcc相关依赖包，使用apt-get代替yum安装相关依赖包

apt-get -yinstall gcc automake autoconf libtool make
    apt-get -y install make*
    apt-get -y install zlib* apt-get -y install openssl libssl-dev apt-get install sudo

## make编译安装 ##

在/var/jenkins\_home/python3/Python-3.6.8目录执行make和make install 安装

./configure --prefix=/var/jenkins_home/python3 --with-ssl
    make
    make install

## 添加软链接 ##

添加python3软链接

> ln -s /var/jenkins\_home/python3/bin/python3.6 /usr/bin/python3

添加pip3软链接

> ln -s /var/jenkins\_home/python3/bin/pip3 /usr/bin/pip3

## 检查环境 ##

输入pip3 和python3检查环境

root@cb8e397d5308:/var/jenkins_home/python3/Python-3.6.8# pip3
    
    root@cb8e397d5308:/var/jenkins_home/python3/Python-3.6.8# python3 Python 3.6.8 (default, Jan 1 2020, 10:15:14) [GCC 6.3.0 20170516] on linux Type "help", "copyright", "credits" or "license" for more information. >>> exit()

使用pip3安装一个requests包

> pip3 install requests

## ssl问题 ##

如果pip3安装的时候遇到报ssl相关问题：pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

这个是因为缺少ssl依赖包，网上的解决方案是`yum install openssl-devel` ,由于Debian系统没有yum,用apt-get安装

> apt-get -y install openssl libssl-dev

安装完成之后只能解决系统自带的python2对应的pip安装问题，无法解决python3的pip3安装问题。

解决办法：上面编译的时候需加上参数 --with-ssl

> ./configure --prefix=/var/jenkins\_home/python3 --with-ssl

重新执行make和make install 就可以了

也可以在python环境检查是否能导入ssl

root@cb8e397d5308:/var/jenkins_home/python3/Python-3.6.8# python3
    Python 3.6.8 (default, Jan 1 2020, 10:15:14) [GCC 6.3.0 20170516] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import ssl >>>
