## **环境** ##

*  Centos 7.4
 *  JDK 1.8

## **主要步骤** ##

以下包含相关所有的步骤，可根据现有环境进行跳过

1.  安装 JDK
2.  安装 Centos
3.  Jenkins 和 Github 配置
4.  配置任务

### **安装 JDK** ###

Jenkins 需要 JDK 才可以运行，我们首先安装 JDK

#### **下载** ####

下载链接查看地址（https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html）

首先点击Accept License Agreement，选择Linux对应版本

***注***若想要直接获取下载链接，使用wget进行下载是不行的，我们可以先点击链接进行下载，然后在chrome中的下载任务中查看下载链接进行复制。

cd /usr/local/src
    wget `your download url`

####     ####

#### **解压** ####

tar -zxvf jdk-8u91-linux-x64.tar.gz

#### **环境变量** ####

将以下内容追加到 /etc/profile末尾,替换你对应的解压路径

JAVA_HOME=/usr/local/tools/jdk1.8.0_144
    JRE_HOME=$JAVA_HOME/jre
    PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
    CLASSPATH=:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib/dt.jar
    export JAVA_HOME JRE_HOME PATH CLASSPATH

#### **启用配置** ####

source /etc/profile

#### **查看版本** ####

java -version

**安装 Jenkins**

使用 yum 进行安装

#安装自动选择最快源的插件
    $ yum install yum-fastestmirror -y
    #添加Jenkins源:
    $ sudo wget -O /etc/yum.repos.d/jenkins.repo http://jenkins-ci.org/redhat/jenkins.repo
    $ sudo rpm --import http://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key
     #安装jenkins
    $ yum install jenkins

####     ####

#### **启动** ####

service jenkins start

**更改端口**

vim /etc/sysconfig/jenkins
    service jenkins restart

### **Jenkins 和 Github 配置** ###

这里的配置就比较多了，主要是在 github 上生成 key,然后在 Jenkins 与项目进行绑定即可

#### **初始化 Jenkins** ####

这几步非常简单，按照提示进行即可

1.  访问你的 IP:8080
2.  cat /var/lib/jenkins/secrets/initialAdminPassword 把密码输入进去
3.  Install suggested plugins 进行安装
4.  设置账户密码

### **配置 Github webhooks** ###

#### **在对项目有写权限的用户上获取 token** ####

进入github –> setting –> Personal Access Token –> Generate new token

![format_png 1][]

点击保存，获取 token,**并保存好你的 token**

#### **设置 webhooks** ####

进入GitHub上指定的项目 –> setting –> WebHooks&Services –> add webhook –> 输入刚刚部署jenkins的服务器的IP

![format_png 2][]

**配置 Jenkins 的 Git Plugin**

新版Jenkins在初始的时候已经默认安装了Git Plugin和相关依赖的Plugin，我们不用在重复进行安装，直接配置即可

系统管理 –> 系统设置 –> GitHub –> Add GitHub Sever

填写 API URL为https://api.github.com

![format_png 3][]

点击旁边的 Add 按钮, 添加 Secret Text

![format_png 4][]

### **配置任务** ###

### **1.新建** ###

回到主页 –> 新建任务 –> 新建一个自由风格的软件项目

![format_png 5][]

**2.配置源码管理**

![format_png 6][]

**3.构建触发器，构建环境**

![format_png 7][]

### **4.编写你的构建脚本** ###

![format_png 8][]

保存，应用

## **问题记录** ##

*  项目会自动 clone 在 /var/lib/jenkins/workspace/
 *  执行的全局脚本确定已经软链到 /usr/bin,否则访问不到
