Jenkins

Jenkin是什么?

Jenkins是开源CI&CD软件领导者, 提供超过1000个插件来支持构建, 部署, 自动化, 满足任何项目的需要, Jenkins是一个独立的基于Java的程序, 可以立即运行, 包含Windows，Mac OS X和其他类Unix操作系统.

Jenkins的特点:

持续集成和持续交付作为一个可扩展的自动化服务器, Jenkins可以用作简单的CI服务器, 或者变成任何项目的连续交付中心.
Jenkins可以通过其网页界面轻松设置和配置, 其中包括即时错误检查和内置帮助.
通过更新中心中的1000多个插件, Jenkins集成了持续集成和持续交付工具链中几乎所有的工具.
Jenkins 可以通过其插件架构进行扩展, 从而为 Jenkins 可以做的事提供几乎无限的可能性.
Jenkins可以轻松地在多台机器上分配工作，帮助更快速地跨多个平台推动构建，测试和部署.

Jenkins部署:

选用Ubuntu进行部署

  • 建议所有操作在root下部署
  • 关于Ubuntu设置永久DNS的方法:

    $ vim /etc/network/interfaces	     # dns-nameserver 192.168.137.2
    $ vim /etc/systemd/resolved.conf	 # [Resolve] DNS=DNS

Ubuntu的相关配置:

192.168.37.10: jenkins/SVN; 192.168.37.12: 测试机; 192.168.37.14: 生产环境
