**1、持续化部署工具 jenkins**

（1）手动打包运行过程

（2）使用jenkins实现完整过程

> **Jenkins（安装）**
> 
> **1、在liunx系统中安装相关软件**
> 
> **（1）安装java环境（jdk环境）**
> 
> 第一步 上传jdk安装介质
> 
> 第二步 解压
> 
> 第三步 配置环境变量
> 
> 第四步 使用命令查看jdk是否安装成功

> **yum  -y  install  git**
> 
> **（4）安装Docker**
> 
> 第一步：安装必要的一些系统工具
> 
> yum install -y yum-utils device-mapper-persistent-data lvm2
> 
> 第二步：添加软件源信息
> 
> yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
> 
> 第三步：更新并安装Docker-CE
> 
> yum makecache fast
> 
> yum -y install docker-ce
> 
> 第四步：开启Docker服务
> 
> service docker start
> 
> 第五步、测试是否安装成功
> 
> docker -v
