1.下载war包

https://jenkins.io/download/

2.安装

java -jar jenkins.war

解决：

修改Jenkins端口java -jar jenkins.war --httpPort=8081

jenkins plugin提示： Update information obtained: 不可用 ago；
出现堆栈错误；
解决：
我们将.jenkins/hudson.model.UpdateCenter.xml文件内容中的https://updates.jenkins.io/update-center.json改为http://updates.jenkins.io/update-center.json即可；即为https协议改为http协议；然后我们重启一下jenkins，插件即可正常搜索访问；
--------------------------------------------------------------------------------------------------
jenkins时区设置为上海时间
打开 【系统管理】->【脚本命令行】运行下面的命令

System.setProperty('org.apache.commons.jelly.tags.fmt.timeZone', 'Asia/Shanghai')

jenkins 关闭和重启实现方式.
1、关闭Jenkins
只需要在访问jenkins服务器的网址url地址后加上exit。例如我jenkins的地址http://localhost:8080/，那么我只需要在浏览器地址栏上敲下http://localhost:8080/exit 网址就能关闭jenkins服务.
2、重启Jenkies
http://localhost:8080/restart
3、重新加载配置信息
http://localhost:8080/reload

3.项目配置（gerrit提交patch动态触发jenkins自动编译）

①建立gerrit服务器连接

②确保手动触发的可执行性

③项目动态触发条件配置

4.构建脚本
