Ubuntu 安装jenkins

首先在jenkins官网上下载jenkins.war包。下载后，将war包上传到jerry/webapps目录下，并在此目录中新建文件jenkins.xml，文件完整内容如下：

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_3.dtd"><!-- ==================================================================Configure and deploy the test web application in $(jetty.home)/webapps/testNote.

注意修改其中jenkins war包的路径。然后cd 到/etc/jetty目录，执行java -jar start.jar 命令启动jetty。启动成功后，访问jenkins：

注意，这里可能需要修改jenkins工作的主目录，后续因为编译任务增多，默认的目录可能不适合。按照如下步骤修改：

使用vi /etc/profile 命令来编辑该文件，在该文件末尾添加：
export JENKINS_HOME=/apphome/jenkins
保存后退出，并在shell中执行source /etc/profile。
重启jetty。
