Linux（Ubuntu16.04）下安装Jenkins
jenkins官网https://pkg.jenkins.io
这是Jenkins的Debian软件包存储库，用于自动安装和升级。要使用此存储库，请先将密钥添加到系统中：
wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -
然后追加下列内容到 /etc/apt/sources.list文件中（apt命令下载时会找下面的地址）
deb https://pkg.jenkins.io/debian-stable binary / 即： sudo sh -c 'echo deb https://pkg.jenkins.io/debian-stable binary / >> /etc/apt/sources.list' 更新您的本地包索引，然后最后安装Jenkins：
sudo apt-get update
sudo apt-get install jenkins
安装jenkins后
sudo /etc/init.d/jenkins start //jenkins服务开启 注意端口号是否被占用（8080）
sudo /etc/init.d/jenkins status //查看jenkins服务开启状态
sudo /etc/init.d/jenkins stop //jenkins服务关闭
查看进程中的jenkins
ps aux | grep jenkins
jenkins的日志（/var/log/jenkins/jenkins.log）
more /var/log/jenkins/jenkins.log
启动jenkins 若端口被占用时，需要关闭jenkins服务，更改被占用的端口（一般是改tomcat的）
再开启jenkins服务，查看下日志是否启动成功！
7.进入选择插件安装界面，选择第一个（Install suggested plugins）
8.插件安装完成之后，需要创建第一个用户
9.创建用户之后，就可以使用jenkins了
附：Tomcat下部署Jenkins (win7)
官网下载http://jenkins-ci.org/
直接下载jenkins.war，网上说放到tomcat的webapps下，直接启动tomcat便可，但是访问
http://localhost:8080/jenkins 出现了以下问题,且出现类似于下面的截图（网上的图），jenkins启动失败！
注：我使用的是apache-tomcat-7.0.75，jekins是2.56版本，jdk是1.8.0_131

网上找了些博客资料如下：
http://www.mkyong.com/java/java-unsupported-major-minor-version-51-0/ 大概说的是major.minor version 52.0 = JDK 1.8 / 8 （可我系统java就是1.8）
结果网上说可以用：java -jar jenkins.war 启动方式，最终启动了
