Build great things at any scale The leading open source automation server, Jenkins provides hundreds of plugins to support building, deploying and automating any project.html
其是一款开源自动化部署服务器，由java编写，目的是为了持久集成。前端
具体步骤
项目和远程仓库
将最新的代码推送到远程仓库
远程仓库和Jenkins
定时获取远程仓库上最新的完整项目下载到本地
Jenkins与远程服务器
经过jenkins上传到远程服务器
安装
先添加其Debian软件包，而后更新存储库,最后使用存储库apt-get安装jenkins。vue
安装运行环境
安装jdkjava
sudo apt-get install openjdk-8-jdk
复制代码
安装完成以下node

修改默认端口8080
修改 /etc/init.d/jenkins 脚本
sudo vim /etc/init.d/jenkins
复制代码
修改$HTTP_PORT改为所需的端口
# Verify that the jenkins port is not already in use, winstone does not exit
# even for BindException
check_tcp_port "http" "$HTTP_PORT" "1314" "$HTTP_HOST" "0.0.0.0" || return 2
# If the var MAXOPENFILES is enabled in /etc/default/jenkins then set the max open files to the
# proper value
复制代码
修改 /etc/default/jenkins 文件
sudo vim /etc/default/jenkins
复制代码
修改HTTP_PORT改为所需的端口

# that sort of things.

# --httpPort=$HTTP_PORT (default 8080; disable with -1)
# --httpsPort=$HTTP_PORT
# --argumentsRealm.passwd.$ADMIN_USER=[password]
复制代码
重启服务器
sudo systemctl restart jenkins
复制代码
改完后重启出现bug
Warning: jenkins.service changed on disk. Run 'systemctl daemon-reload' to reload units.
复制代码
解决方法：
systemctl daemon-reload
复制代码
systemctl start jenkins
复制代码
新端口是1314
启动jenkins
sudo systemctl start jenkins
复制代码
用下面命令测试或者直接ip+端口或者0.0.0.0:8080访问jenkins
sudo systemctl status jenkins
复制代码
成功以下：

Which events would you like to trigger this webhook?选择just the push event
选择Active
点击Update webhook
jenkins拉取github上vue代码在本地启动
新建任务
任务名随意
选择构建一个自由风格的软件项目，最后肯定
绑定github项目
绑定项目的下载连接
选择Git
在Repositories中的Repository URL填入项目下载连接(http)
Credentials中添加身份信息
在类型中选择Username with password
用户名和密码就是github的帐号和密码，最后肯定
Branches to build选择部署的分支(*/分支名)
构建触发器
选择GitHub hook trigger for GITScm polling
构建
执行shell
命令
cd /var/lib/jenkins/workspace/vue
npm install chromedriver --chromedriver_cdnurl=http://cdn.npm.taobao.org/dist/chromedriver
npm install
npm run dev
复制代码
cd /var/lib/jenkins/workspace/ceres-cms-vue
npm install chromedriver --chromedriver_cdnurl=http://cdn.npm.taobao.org/dist/chromedriver
npm install
npm run build
npm run pm2
pm2 list
复制代码
仓库代码更新自动构建
不用勾选定时构建和轮询SCM
勾选GitHub hook trigger for GITScm polling
这样你的jenkins就能够随着你的代码自动构建了
轮询
定时构建：不管有无最新代码，都按时构建
轮询SCM：只要代码有更新，都会构建
构建语法说明：
首先格式为：* * * * *（五个星）
选项
意思
第一个*表示分钟
取值0~59
第二个*表示小时
取值0~23
第三个*表示一个月的第几天
取值1~31
第四个*表示第几月
取值1~12
第五个*表示一周中的第几天
取值0~7，其中0和7表明的都是周日
使用举例（不加H为时刻以前）：
选项
意思
每隔1分钟构建一次
H/1 * * * *
每隔1小时构建一次
H H/1 * * *
每个月1号构建一次
H H 1 * *
定时构建和轮询SCM使用互不冲突，具体如何组合，须要根据项目状况合理配置；
