当gitlab上代码发生变更时，jenkins自动将代码部署到服务器上，常用于测试环境

实现方法

在gitlab上创建一个新的开发分支

在jenkins上安装插件

插件安装完毕后需要对jenkins的配置做一些更改：

1.允许登录用户可以做任何事情

2.关闭跨站伪造保护

新建一个开发分支的任务

生成一个token值

root@jenkins:~# openssl rand -hex 12

填入token值

测试访问连接

#jenkins的地址、job和token拼出的连接，一旦访问此连接将触发构建
root@jenkins:~# curl 192.168.27.12:8080/job/mylinu_develop/build?token=2d6f3d9475277d20545a4182

url测试通过后将其写入gitlab
