1. 极简概述
Jenkins是一个独立的开源自动化服务器，可用于自动执行与构建，测试，交付或部署软件相关的各种任务，。
Jenkins可以通过本机系统软件包，Docker安装，甚至可以由安装了Java Runtime Environment（JRE）的任何机器独立运行。
2. Jenkins配置
安装Jenkins很简单，首先安装Java8，然后再安装Jenkins，这里使用Jenkins的2.173版本。包的话，直接去官网下载吧。
2.1 安装JDK
(1) 解压JDK
[root@jenkins ~]# tar zxvf jdk-8u171-linux-x64.tar.gz
[root@jenkins ~]# mv jdk1.8.0_171/ /usr/local/java
(2)添加环境变量
[root@jenkins ~]# vim /etc/profile # 写入如下内容
export JAVA_HOME=/usr/local/java
export PATH=$PATH:$MAVEN_HOME/bin:$JAVA_HOME/bin
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
(3) 立即生效
[root@jenkins ~]# source /etc/profile
[root@jenkins ~]# java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)
2.2 安装Jenkins
(1) 直接用jre跑
[root@jenkins ~]# java -jar jenkins.war --httpPort=8080
(2) 访问Web
http://localhost:8080
(3) 跟着配置
注意：如果这一步出现：Problem accessing /setupWizard/createAdminUser. Reason:，那么直接使用admin登陆。
(4) 安装插件Open Blue Ocean
Blue Ocean为开发人员提供了更具乐趣的Jenkins使用方式，它是从基础开始构建的，实现了一种全新的、现代风格的用户界面，有助于任何规模的团队实现持续交付。它以Jenkins插件的方式安装，并集成于Jenkins的流水线中。
注意：版本2.165可能出现安装失败。解决方法未知。
3. 安装Docker
（1）安装依赖
[root@jenkins ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
[root@jenkins ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
[root@jenkins ~]# yum install docker-ce docker-ce-cli containerd.io
[root@jenkins ~]# sudo systemctl start docker
[root@jenkins ~]# docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
1b930d010525: Pull complete
Digest: sha256:92695bc579f31df7a63da6922075d0666e565ceccad16b59c3374d2cf4e8e50e
Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID:

https://docs.docker.com/get-started/
4. 使用PyInstaller构建Python应用程序
必须条件：
- GitHub账号
4.1 Fork 一个库
该存储库中包含一个简单的Python应用程序，它是一个命令行工具“add2vals”，它输出两个值的相加。如果至少有一个值是字符串，则“add2vals”将这两个值视为字符串，而是将值连接起来。
链接为：https://github.com/jenkins-docs/simple-python-pyinstaller-app
4.2 克隆项目
# 自己创建GitHub这个目录
[root@jenkins GitHub]# pwd
/root/GitHub
[root@jenkins GitHub]# git clone https://github.com/liuhedong135/simple-python-pyinstaller-app.git

4.3 在Jenkins创建管道项目
[root@jenkins GitHub]# ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
Generating public/private rsa key pair.

最后点击下载，并传入到linux，
[root@jenkins ~]# ls -lh
total 3.4M
-rw-r--r-- 1 root root 3.4M Apr 21 10:54 add2vals
drwxr-xr-x 3 root root 43 Apr 22 09:32 GitHub
[root@jenkins ~]# chmod +x add2vals
[root@jenkins ~]# ./add2vals
You entered 0 value/s.
Usage: 'add2vals X Y' where X and Y are individual values.
If add2vals is not in your path, usage is './add2vals X Y'.
If unbundled, usage is 'python add2vals.py X Y'.
[root@jenkins ~]# ./add2vals 1 1
The result is 2
最后我们就成功的将应用打包，并在linux上运行，这个应用是一个简单的计算。
