1. Jenkins简介

Jenkins是一个独立的开源软件项目，是基于Java开发的一种持续集成工具，用于监控持续重复的工作，旨在提供一个开放易用的软件平台，使软件的持续集成变成可能。前身是Hudson是一个可扩展的持续集成引擎。可用于自动化各种任务，如构建，测试和部署软件。Jenkins可以通过本机系统包Docker安装，甚至可以通过安装Java Runtime Environment的任何机器独立运行。

2. Jenkins功能

Jenkins功能包括:

• 持续的软件版本发布/测试项目。
• 监控外部调用执行的工作。

3. 启动

• 首先保证系统中已经安装了jdk，最好是jdk1.5以上。
• 第一种启动方法，切换到jenkins.war存放的目录，输入如下命令:$ java -jar jenkins.war
• 如果需要修改端口可以使用如下命令:
• $ java -jar jenkins.war–httpPort=8081
• 然后在浏览器中(推荐用火狐)输入localhost:8081，localhost可以是本机的ip，也可以是计算机名。就可以打开jenkins。
• 第二种方法是用tomcat打开
• 解压tomcat到某个目录,如/usr/local，进入tomcat下的/bin目录，启动tomcat将jenkins.war文件放入tomcat下的webapps目录下，启动tomcat时，会自动在webapps目录下建立jenkins目录，在地址栏上需要输入localhost:8080/jenkins。

4. tomcat部署
