1.docker安裝

# centos7 安裝docker
1 安裝依賴
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
2 設置docker yum源為阿里雲
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
  
3 安裝
sudo yum install docker-ce -y
4.配置阿里雲加速器cd /etc/docker 
  daemon.json 文件
  vim  daemon.json
  加入阿里雲加速器地址  72idtxd8隨便填
  { "registry-mirrors": ["https://72idtxd8.mirror.aliyuncs.com"] } 
  保存后，重啟docker拉取鏡像的速度嘎嘎的

2.安裝jenkins

docker pull jenkins/jenkins:lts  # 拉取鏡像
docker image ls -a    # 查看所有鏡像
docker image  inspect  鏡像id  # 查看jenkins的詳細信息及版本
mkdir /home/jenkins_home  # 創建一個jenkins映射目錄
docker run -itd --name=jenkins_01 -p 9090:8080 -v /home/jenkins_01:/home/jenkins_01 jenkins/jenkins:lts
解釋： i 運行容器 it 運行容器 並進入容器執行命令 itd 不會進入容器  --name 給容器起名字   -v 映射目錄

進入容器

docker exec -it jenkins_01 bin/bash
cat /var/jenkins_home/secrets/initialAdminPassword

選擇安裝推薦的插件

設置賬戶密碼安裝完成

重啟：http://你的ip地址:9090/restart

安裝python3 環境

1.官網下載安裝包
https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
Python-3.6.5_.tgz
2. copy 到容器中   或者進入容使用wget下載   在使用容器中使用wget下載比較慢時
docker cp Python-3.6.5_.tgz jenkins_01:/var/jenkins_home/python3

進入容器

docker exec -it -u root 容器id /bin/bash  #進入容器

換源阿里

查看系統，

cat /etc/issue

此時系統默認是debian 9系統，這里yum是沒有的，所以不能用yum安裝了，這里用apt-get代替yum，

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

Debian安裝軟件巨慢，換Debian源為阿里源

注意：換源要對應strech

5是Debian      6是squeeze
7是wheezy      8是jessie
9是stretch

cat /etc/apt/sources.list

內容改為

deb http://mirrors.aliyun.com/debian/ stretch main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch main non-free contrib
deb http://mirrors.aliyun.com/debian-security stretch/updates main
deb-src http://mirrors.aliyun.com/debian-security stretch/updates main
deb http://mirrors.aliyun.com/debian/ stretch-updates main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch-updates main non-free contrib
deb http://mirrors.aliyun.com/debian/ stretch-backports main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch-backports main non-free contrib

更新apt-get

apt-get update

jenkins 容器內安裝python

cd /var/jenkins_home/
mkdir python3
cd python3/
docker cp Python-3.6.5_.tgz jenkins_01:/var/jenkins_home/python3   # 從宿主機中copy到容器中
tar -xvf Python-3.6.5.tgz
cd Python-3.6.5
./configure --prefix=/var/jenkins_home/python3

安裝gcc相關依賴

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

make編譯安裝

在/var/jenkins_home/python3/Python-3.6.8目錄執行make和make install 安裝

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

添加軟連接

添加python3軟鏈接

ln -s /var/jenkins_home/python3/bin/python3.6 /usr/bin/python3

添加pip3軟鏈接

ln -s /var/jenkins_home/python3/bin/pip3 /usr/bin/pip3

檢查環境

輸入pip3 和python3檢查環境

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安裝一個requests包

pip3 install requests

pip 換源

 vim  /etc/pip.conf  # 沒有就新建

修改內容為：
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple

這時候pip3 install requests 會很快

ssl問題

如果pip3安裝的時候遇到報ssl相關問題：pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

這個是因為缺少ssl依賴包，網上的解決方案是yum install openssl-devel ,由於Debian系統沒有yum,用apt-get安裝

apt-get -y install openssl libssl-dev

安裝完成之后只能解決系統自帶的python2對應的pip安裝問題，無法解決python3的pip3安裝問題。

解決辦法：上面編譯的時候需加上參數 --with-ssl

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

重新執行make和make install 就可以了

也可以在python環境檢查是否能導入ssl

root@cb8e397d5308:/var/jenkins_home/python3/Python-3.6.8# python3
Python 3.6.8 (default, Jan  1 2020, 10:15:14)

>>> import ssl
